3 Important Home Insulation Q&A

Living in the harsh climates of North America could be really tough. And using conventional heating appliances does not prove to be sufficient for combating with cold. Homes that are located in very harsh climates be it cold or hot climate, need to be insulated in order to keep them warm in Winters and cool in Summers. While the insulation keeps the inside warmth trapped in the Winters and doesn't let the outer cold blows reach the indoor, it also keeps the indoors cool in Summer by not allowing the outdoor heat to reach the inside of the house. This way, insulation works great wonders to maintain a desirable indoor environment in all seasons while making only a limited use of HVAC appliances. But not all homes are insulated. Homes built before 1940’s are either non-insulated or insulated poorly. If yours is one such home that you think needs to be insulated, consider these tips;

How do I decide that my home needs insulation?
That ain't a rocket science. To discover whether your insulation has worn apart, check the attic for loose fills or batts of coloured fibreglass that are exposed. Check exterior walls for patched holes to know if the blown in wall insulation has been made sometime in the past. Roof in one big way to ensure whether or not the home is well insulated. Heat rises from the top and homes that have poor or worn out insulation can have warmer roofs. So here's how you can decide whether or not your home needs insulation but the biggest sign could be you and your family shivering despite having efficient heating appliances.    

Which and how much insulation do I need?
There are different types of insulation materials available in the market, each with its own specific ''R'' value. The R-value is basically the material's heat flow resistive value. Higher the value, higher the resistivity, lower the values, lower the resistivity. Materials with high R values are recommended for harshly cold climates like Chicago while those with low R-value are recommended for warmer climates like Florida. So, the type of insulation depends on the type of climate you live in. Similarly, how much and in which parts do you need insulation depends on several factors;
- The location of your home
- The architecture of your home
- Your budget
- Your preferences (some people are allergic to certain types of insulation material)

How to combat moisture problem when retrofitting insulation?
When retrofitting insulation, there's a problem that put homeowners at great unease and that is of moisture. The moisture that is formed as a result of cooking, bathing, hydronic heating etc reaches the walls and cavities and condenses in insulation material resulting in mould growth, rotting wood or peeling paints etc. In order to combat this problem, it is suggested to face the insulation materials vapour barrier towards the inside of the house in order to avoid the above-mentioned consequences. This is for colder climates. However, the places that see harsh Summer heat and vaporization occur as a result of moist air that travels from outside towards inside, the point of view differs. Better consult your nearby HVAC professional.

6 wise investments that will help you save energy and dollars

What a wonderful season Winter is. A time when snowflakes look like cotton candy falling from the sky, the cool breeze feels like dry cleaning everything around and the hot chocolate & coffee adds to the joys of the Winter when one is lost recalling old memories. There's a lot of joys that are associated with the Winter but there's one worry as well that is linked with it and is common to all homeowners. That is to keep the indoors comfortably warm while also keep the energy bills in control and this is not easy when the temperature outside falls below zero. There are several energy efficient appliances in the market now that are a promising solution to lower energy bills but as the appliances are constantly used, hefty energy bills are a clear consequence. We want you to have enough money to enjoy all the Winter joys so let us talk about the energy saving tips for Winters. Act a little smarter and you will attract dollars back to your wallet.

- Blinds and curtains aren't there just to serve an interior appeal, they are also a source of heat loss just like they are a source of fresh air intake. In Winters, brace yourself for a smart use of these curtains and blinds. Open them in the day when there's Sunlight that can provide the indoor with warmth and close them when there's no source of heat from outside in order to avoid heat loss. This practice might seem ordinary but has the potential to save big.

- Homeowners often leave home appliances turned on as they rush outside the house in hurry. The primary reason for that is they find it hard to switch off appliances one by one. But this swallows a lot of energy units since the appliances when they are switched on continue to take up energy even when, not in use. A quick combat to this laziness is the use of power strips. Use power strips so that you could turn appliances off with one single button.  

- Motion sensors and lighting controls are one wise investment you can make for the entire year. The motion sensors detect movement so when you are away, they automatically turn the electrical connections off.

- You were right if you took sealing windows and doors seriously. They are a big source of heat loss in Winters but there's one more wise investment that you can make and that is by installing energy efficient doors and windows. These doors and windows do not let pass any air through them and are therefore the best combat for heat loss in Winters

- Home insulation has a great potential to lower energy bills by up to 25%. It might seem a hefty investment but it does return your investment with the savings it serves. Insulation once done suffices for several years.

- All things aside, installing a Smart Thermostat can totally astonish you. Not only does this device help save great on energy bills, it also helps extend the lifetime of the appliances by controlling their use.

We have mentioned 6 investments that have the potential to save energy as well as money. But if you're not in a position to make any investment but still want to lower the energy bills while also don't want to die from cold, then try this; make limited use of heating appliances and in order to keep yourself warm, use the layering trick. Wear as many layers of warm clothes as you can.


Time to replace your Furnace!

Think of waking up in the midnight to strange noises. Stepping out of the bedroom and standing right on the staircase, you hear the sound coming from the basement. Gosh! The Furnace is again making those awful noises.
Did this ever happen to you? If yes, you clicked the right page. Furnace users face this and similar situations often. Although such noises do not always necessarily mean that your system is seeking a repair, there are times when they do and do it clearly. Before your system fails on a cold Winter night, take some time to have the noises diagnosed by a professional. In addition to the noise factor, there are some other indications that the Furnace system gives well before taking its last breath. Today, let us help you explore those indications.
  • Age Counts
Before you go on to check any other symptoms of a Furnace expected to fall, a must consider factor is the age. If the unit has already completed its lifespan, there’s no need to suspect any further critical complexities. Go for a replacement! The average lifespan of a furnace is 16-20 years so if your system has reached this age, this is the good time to purchase a new unit.
  • Rising energy consumption
If your electricity bills are rising to a higher extent, if so it may be caused by inefficiencies that come with an outdated furnace. The less efficient a Furnace will become, the more electricity it will suck. Old unit + Rise in energy bills = Go for replacement
  • Irregular or uneven heating
The reason why Furnace is an ideal heating element for many homeowners is its ability to heat the indoors evenly. If your home no longer remains at an even temperature and the Furnace unit is old enough as well, you should better consider replacing your furnace. Your ageing heating system may not be able to distribute warm air evenly causing some rooms to be hot and others to be cold. That's absolutely irritating!
  • Unusual noises
So we just talked about noises in the beginning. Let's talk about them again. Are you hearing some weird noises from your Furnace? Bangs, rattles and changing fan sounds are obvious indications that your furnace may be the at the end of its life.
  • Frequent repairs
If your Furnace frequently asks for a repair, it is actually begging you to bring another unit in its place. If the repairs are costing you every other day, why not make a wise investment and replace the unit with a better model?

As said already, the symptoms show up for several reasons and it is not always a replacement that the unit is seeking, it is, for most of the times. A careful approach is to reach professionals before making the decision of investment. Call a reliable HVAC pro and have your Furnace system diagnosed thoroughly. But even in that case, there are homeowners that doubt HVAC technicians for not giving proper advice, a much wiser approach is to consult multiple technicians, particularly in the case when your system isn't old enough to be considered for the question of replacement. Consult and then decide.


Interesting facts about HVAC system

Did you notice? All those ''Interesting Facts'' are about everything but HVAC. Why that injustice when there are numerous HVAC facts that are interesting and need to be talked about? No one tells so we thought to give a shot to the interesting HVAC facts that the commoners are either partially or completely unaware of. Brace yourself!
First ever AC was installed in New York
Did you know, the first ever Air Conditioner was installed at a publishing company based in New York in 1902. The need for an AC installation was felt when the publishing company faced the issue of uneven drying of paper ink due to high humidity in Summer. To cope this issue, the first ever commercial Air Conditioner was installed at that company.

Size of the Air Conditioner is getting larger
You read it right. Although the size of so many other technologies is getting smaller; computers, phones etc, the size of the Air Conditioners has recently become larger and the primary reason is the increase in the demand of minimum efficiency rating which calls for larger AC units.

Movies were watched for cooling
Here's an interesting fact that you might never have heard before; people used to go to movies not just to watch movies but in the hope of cooling themselves off in hot Summer since the theatres were Air Conditioned and Air Conditioning was not available at that time for common households in the 1930s. So every time they felt hot, they planned for movies.
Huh! Thanks, mother technology for making our homes Air Conditioned. We can watch movies along with a wonderful indoor temperature within the comfort of our homes.

Postponing filter changing can cause system breakdown
9/10 HVAC system breakdowns are caused by lack of maintenance and primarily because of dust and debris. While you might think changing Filters is a 5-minute task and, therefore, is not of any prime importance, you are wrong. Not changing Filters regularly can take your system to the verge of complete breakdown. Clogged filters do not allow a smooth airflow. This makes the motor of Furnace / Air Conditioner to work harder than usual. Although they do bear this overloading for some time, they also end up doing so at any time if the Filter maintenance is completely ignored.

HVAC techs need to licensed
Most homeowners never ask for a license when an HVAC tech reaches them. Although it is the duty of the tech to show his work license before he begins the work, it is also a homeowner's responsibility to ask for the working license from an HVAC technician in order to make sure he is able and experienced to perform the job with satisfaction.
Closing supply vents of unused rooms harm the system
How many times have you heard this suggestion? Of closing the vents of unused rooms? More than many times. The truth is; doing so harms the system because the supplied air doesn't get the passage to enter the rooms and either remain in the duct or returns back from the same passage without changing its temperature, This affects the system's overall efficiency.  

''Summer Breaks'' started due to hot Summer and no Air Conditioning
Did you know ''Summer Breaks'' in schools started in the 1900's when it started to be extremely hot and there was not sufficient Air Conditioning to cool the schools of. In addition to the schools, some other government buildings were also shut off due to the same reason.

HVAC systems don't break up without showing symptoms
Yes, that's true whether or not you agree with it. There are several homeowners who complain that their system broke down suddenly one day. That cannot be true. HVAC system shows symptoms before breaking down. The reason for some people, the breakdown is sudden because they don't pay attention to the symptoms it shows.

That's all from our side for today. Did you find these facts interesting? Do you have any other HVAC interesting fact to share? Share!


Coil Cleaning - 4 Problems 4 Solutions

Air Conditioner technology has now gone old enough and is widely used in common households. Though the use has become common, the basic HVAC awareness troubleshooting still needs to be made common so that homeowners could use their appliances in the right way and could fix them in the right time. This blog talks about some Air Conditioner Coil problems and their solutions.  


Problem#1: Coil Corrosion
One of the primary reasons for Air Conditioner failures and other industrial and home appliances failure is corrosion. As the humidity level and temperature increases, the chemical reactions take place fastly, resulting in corrosion of appliance parts mainly the ones that undergo chemical reactions inside them. Air Conditioner coils corrode because of the same reason. In addition to the temperature effects, another cause of corrosion is the use of caustic, oxidizing and acidic gases and using acidic solutions for cleaning purposes.
The solution is; Eradicate the causes of corrosion! Use non-corrosive chemicals. For cleaning purposes, use corrosion inhibiting and less penetrating agents.

Problem#2: Curved Air Conditioner Coil Fins
Using high-pressure water for cleaning purposes often damage the coil fins and cause them to bend. Other times it is the cleaning chemicals that are too reactive that cause a chemical reaction to take place between the chemical and the coil surface which over time, results in loss of metal.      
Using special equipment and a low-pressure, high-volume formula for cleaning, the coils can be cleaned safely and properly. Also, if a cleaning agent is used, it is highly recommended to use only those cleaning agents that are recommended by professionals in order to avoid any possible damages.

Problem#3: Spray Damages
Keeping Air Conditioner unit close to sensitive property; plants, trees etc can cause serious damage to them as the chemical cleaning is performed. While it is important to use non-corrosive chemicals, it is also important to use chemicals that pose no harm to the nearby property.
If the plants can be moved, move them away from the unit at the time of cleaning or cover them properly else, use plant friendly chemicals. Also, rinse the chemicals properly or otherwise the residual chemicals leave marks and cause corrosion.  

Problem#4: Frozen Evaporator Coils
Frozen evaporator coils is a commonly faced problem. The primary reason of ice buildup on evaporator coils in Summers is a leaking refrigerant. Freon (refrigerant) leaks out of the refrigerant coils and builds up ice beds on the coil. This continuous leaking of refrigerant completely empties the refrigerant gas/liquid, the absence of which makes cooling impossible.  
Refrigerant needs to be refilled but before that, the leaks have to be patched. It is important to patch the leaks properly or seek professional help for the task. Improperly patched leaks keep on leaking the refrigerant resulting in refrigerant loss and needing continuous refilling.

Professional and reliable Coil Cleaning Services:
While there are numerous issues involved in DIY Cleaning that can further lead to other problems, a safer way is to choose professional cleaning services and learn from professionals first how exactly to perform the cleaning.
At Cosmopolitan Mechanical Services Inc. we offer professional Air Conditioner cleaning and maintenance services that involve a proper diagnosis of the appliance, professional maintenance / tune up and expert guidelines. Whether you're having a hard time cleaning the coils, have a refrigerant line issue, want chemical cleaning of coils of something else, contact us for professional and reliable services.

How Attic Insulation affects HVAC efficiency

Ever wondered why HVAC professionals emphasise on the importance of home insulation particularly Attic Insulation? There are wonderful benefits that the Attic Insulation offers but before discovering that, it is important to learn how much energy loss does an uninsulated attic causes you. Roughly, 15% of energy is lost in the attic when it is not insulated.

- Less use of appliances - Energy Saving

An insulated attic home is warmer than usual homes in Winters and cooler than usual homes in Summers. It is because the layer of insulation material keeps the heat and cold outside and bars the outdoor environment to the maximum to affect the indoor environment. As a result, the homes that have their attic, walls or basement insulated require the less use of HVAC appliances since the home easily gets cool in Summers and warm in Winter. Less use of HVAC appliances means saving on energy bills. A one-time insulation that lasts for several years helps save monthly on energy bills.

Attic Insulation

- Less use of HVAC appliances - Extended appliance life

Although a rough estimate of all HVAC appliances is given. For instance, Air Conditioners are supposed to have a lifetime of 10-15 years, Humidifiers a lifetime of 5-10 years, Thermostats a lifetime of 5 or more years etc. However, the fact is; the lifetime of HVAC appliances can be extended. The life expectancy depends on the use and abuse of the appliance. Appliances that are overused break down earlier than the estimated lifespan and those that are used relatively less help comfort for years long. The connection of Attic Insulation with the extended lifespan of HVAC appliances is that insulated homes make less use of heating and cooling appliances. This automatically increases the efficiency as well as the life expectancy.  

- Less use of HVAC appliances - Eco-Friendly

One shouldn't always be thinking only of his own benefits. The times that we are living in are the times of high level of air pollution and the United Nation's Framework Convention on Climate Change has emphasised on the importance of reducing the current level of air pollution else it will adversely deplete the ozone giving way to extremely serious consequences. We know that HVAC appliances including the Air Conditioners, Furnaces, Air Cleaners, Humidifier and others produce residual gases or chemicals that are not safe for the environment. Air Conditioners particularly have been producing the CFCs that are proven to have made serious damage to the environment. Home Insulation and particularly the attic insulation keeps the indoor environment moderate and a limited use of HVAC appliances help save the environment from pollution. Having the home insulated is like thinking for yourself and thinking for the world.

Other Benefits

In addition to the above-mentioned benefits, the other benefits of Attic Insulation include a better indoor air quality since an insulated home does not allow the outside pollution to peek inside. This is helpful in Spring and particularly for the people suffering from COPD. Moreover, an insulated attic reduces the level of outdoor noises.



Does your wife always fight over Thermostat? Do this

Sounds funny? Doesn't it? But if you already have had fights over Thermostat, you can relate to the very statement. It is no gender stereotype, it is in fact, as fact that men and women feel differently when it comes to the outside temperature. So this happens in almost every home that females want the Thermostat to be turned a few degrees up while males of the home prefer it to be turned down to produce more cooling. Today, we'll explore why exactly do men and women have different temperature needs and living in a family, how to fix these differences wisely.

Thermostat Fights

Men feel different than Women because:
There is a genetic difference
We know men are different than women when it comes to genetics. These differences are also present when it comes to body temperature.
Studies show that women have an evenly distributed layer of fat that helps them store heat to their core organs, however, this same layer of fat also contributes in making them feel colder than men because all the major heat goes to the core organs. As a result, as soon as there's a little decrease in the outside temperature, women begin to feel colder and this intensity is more than what men feel because they have heat throughout their body and because of having uneven layers of fat, the heat is spread in most parts to help face the drop in outside temperature.

There's another thing we know about the men-women genetic differences and that is; men have a higher metabolism than women. Since metabolism is responsible for producing bodily heat, bodies of men are warmer than that of women's. This is why women want more outside heat than men.

How to fix Thermostat fights?
It's okay to do nothing if your fights are just little fights that fix up and the difference you and the other member/members feel is just a slight difference but in case it is otherwise; your fights are serious then fix the problem right away with one of the two solutions mentioned below:

- Switch to Programmable Thermostats
There's a wide range of Programmable Thermostats in the market that allow up to 7 days of scheduling. Using a Programmable Thermostat, the temperature of husband's choice can be auto set at his expected time to come home so that he doesn't complain about the temperature. And the wife can enjoy the cooling of her choice through the rest of the day. It's like 50/50.

- Switch to Zoning System
But as said earlier, if your fights and the temperature difference both are serious, you too need to take serious steps. The Programmable Thermostat idea is good but it can still not provide with all time temperature of your choice. A better choice then is Zoning system. By switching to zoning system, it's like everybody having his own Thermostat. Zoning supports up to 7 zones/rooms to be conditioned with different temperatures using one single AC unit. So now you can have a different temperature in the living room and different in the bedroom, different in the kid's room and different in the guest room depending on the requirements of the inmates. And yes, there's no need to fight over the poor Thermostat now. Convert your HVAC system to zoning and the next time it feels like you need more cooling, just go to any room and set the temperature of your choice. Sleep tight!  


Gas vs Electric Furnace - What to choose?

Everything comes with pros and cons. Same is true for Residential Furnaces. While homeowners begin their quest for Furnace purchase, they are often confused between Gas and Electric Furnaces. Although both these Furnaces are efficient and useful, the suitability varies from home to home depending on many factors. A gas Furnace might be the best option for a certain home while an Electric Furnace could be better for some other.
Here we mention the pros and cons of both Electric and Gas Furnaces.  


Electric Furnaces: $670 - $2000

The Pros
If you're low on budget, Electric Furnace could be the best choice for you since they need least initial investment. When it comes to Electric Furnaces, neither storage tanks are required nor special venting and fuel pipes. In addition to that, the Electric units are easy to install small units that can also easily be relocated if the need arises. Also, since Electric Furnaces do not use gas, there is no combustion or risks of gas leaks. Moreover, the lifespan is fair enough; 15-20 years.  
The Cons
Although technology has improved the efficiency of Electric Furnaces way more than their older efficiency, an improvement is still required to make them compete the efficiency of Gas Furnaces. Due to lower efficiency, Electric units are suitable for the less cold climates since they fail to work efficiently in intensely cold weather. Nonetheless, Electric Furnaces are the only choice for homes where there is no gas availability.

Gas Furnaces $1200 - $2,400

The Cons
It is a hefty investment that you'd be making particularly if you're installing a new system altogether since new gas lines will be required as well as an extensive ductwork. A Gas Furnace requires an investment of minimum $1000. If you're on low budget, Gas Furnace is certainly not what is recommended for you.
The Pros
But what begins with huge investment returns in long run. Natural Gas is the cheapest fuel available in Canada. While running a Furnace on Electricity could be costly in terms of utility bills, Gas Furnaces helps save in long run. In addition to that, they are far more efficient than conventional Furnaces and are, therefore, perfect for intense cold climates.

Which Furnace Brand to choose?

After choosing between Electric or Gas, the next thing that causes great bewilderment is which brand to choose? Well if it's not the first time you're purchasing a Furnace, you'll have an easy time choosing depending on your prior experience. The best way to choose the most suitable brand is by making a brand research, checking for customer reviews and most importantly analysing the product's compatibility with your home. One more thing to consider is the warranty. No all companies offer a long warranty. Better to go for a brand that offers as long a warranty as possible.  Our recommendations are Lennox, Amana, Carrier, Rheem and York in particular. While Rheem has been titled the brand that requires least repairing, York has remained the most energy efficient brand in 2013, 2014 and  2016. If there still remains confusion, better throw the ball in the court of an HVAC professional and let him choose for you depending on your requirements.

At Cosmopolitan Mechanical Services Inc. we sell Gas as well as Electric Furnaces of Lennox, Amana, Rheem, York and Carrier. Also, we help homeowners in choosing the right brand by offering Free HVAC consultation.

All about Air Duct Cleaning - 2017

The simplest answer to the question, ‘’Why do Air Ducts need cleaning?’’  is, because they get dirty. Don’t you clean what gets dirty? Then why not ducts? Suppose you haven't cleaned the air ducts since long and have forgotten about changing filters too, what do you think will be inside the duct? Dirt, germs, moulds, hair etc get stuck there, that then become part of the circulating air consequently polluting the air of your house without you seeing it with your naked eye. This pollution, however, can be sensed in the form of flu, breathing problems and various allergies. Well, this is why air ducts need cleaning time to time because the dirt that gathers within the duct cavities drastically affect the indoor Air. Although Filters are of great help, they cannot trap pollutants 100%.


How often should you clean your Ducts?

This question is mainly asked by people who rely on themselves for the cleaning purpose. It is better not to clean ducts more than what is necessary for the reason that continuous opening of the grills of the air duct invite noticeable contaminants and dust into it. The suggested time period of Duct Cleaning is at least once a year whether it is done by individuals themselves or by professionals.

Quick Tips for Duct Cleaning

There are several homeowners who prefer DIY Duct Cleaning. Nothing bad in doing so if one has performed the cleaning process earlier and is veteran enough to perform it like a professional. If you plan for one such DIY Duct Cleaning, here's where to start from:
You have to take precautionary measures for yourself first that include:
1) Wearing a face mask to prevent any type of allergies and dust from going into your lungs.
2) Wear soft fabric gloves as they will protect your hands and will allow you to do your work with ease.
3) Use clean equipment such as a clean vacuum cleaner for maximum suction of dust and debris.
4) Be sure to use a heavy duty vacuum for this purpose as the regular house-cleaning vacuum won’t work as good in this case.
5) Make sure of cleaning the ceiling grilles afterwards.

The total cost of Duct Cleaning

If you are cleaning your ducts after several years, you will have to spare out a significant amount for buying the mandatory equipment. The heavy duty vacuum cost will be the main equipment involved. But if it's a regular process that you do every year, it will not cost as much. You will only have to spend money on little things such as the mask, gloves, blowers, brushes and a few other tools. To put it all together, this process may cost somewhere between $100 - $200.

Professional Duct Cleaning 2017

With the passage of time, people are becoming more aware of the importance of Duct Cleaning. Every year more and more Canadians are moving towards Duct Cleaning that too from professionals since a DIY Duct Cleaning is hectic, time-consuming and sometimes risky too. So the question is, how much would it cost in 2017 if you go for professional Duct Cleaning? Although it depends on per square feet, the minimum cost for Duct Cleaning is $200, however, an estimated maximum for larger areas is around $800.

Bottom Line

To improve the breathing experience at home, save yourself from allergens and maintain a tidy indoor environment, consider Duct Cleaning as an important investment in 2017.

Troubleshoot your Water Heater Problems

Professionals are not always available so it's good to learn some tactics so that you could do things on your own. You might be living in an area where there's no professional service available or face an emergency situation and there's no emergency service in the nearby area. Knowing some DIY hacks is cool as well as benefiting particularly for the times of emergency.
So here, we're presenting some ways to troubleshoot your water heater.

Common Tankless Water Heater Problems
There are a number of problems that the tankless water heater show. The most common of which are; strange sounds, strange smell, rust in water, insufficient provision of hot water and others. These problems do not necessarily need professional help. Just a bit of know how and you're done to troubleshoot your water heater on your own. Hold the gun. Shoot shoot!


No hot water at all! What happened?
People are often exhausted when the hot water provision suddenly stops. Since in the case of tankless hot water, we are supposed to never run short of hot water, a non-supply doesn't make sense. But the trick is simple. The circuit breaker has the problem (in most cases) As the circuit disturbs, the system disturbs and thus fails to provide hot water. So when this happens, check the circuit to see if the current is passing through the terminals. Next, press ''Reset'' and gurrrr the hot water supply has started again.

Noisy Tank
One reason why the tank of a Tankless Water Heater makes noises is the very process of heating. Heating of cold water may produce some noise but you can easily suspect between a normal and an abnormal noise. The reason why a tank would make weird noises is that it has air flowing through it. This can be caused due to leaks in the water supply pipelines. These leaks allow the air to enter into the pipeline. Also, check the thermostat to make sure the water doesn't boil. Tightening of the valve and fixing of the thermostat can easily fix this problem. If there's a minor pipe leak, use a suitable mixture to seal it.

Brownish Water
Sometimes, on turning the hot water supply on, a brownish colour water comes out. This indicates one of the two problems. Either the water you're receiving through the supply lines is dirty or the inner lining of the water heater has been subjected to rust. In the first case, the solution is to install a water purifier at the main supply line if you're concerned about taking bath with clean water. The solution for the rusted inner lining is nothing better than a replacement. Since the water heater is damaged from the inside and will soon completely corrode, any investment on repair will only be a waste of money.

Does water heater lay eggs? From where comes this rotten egg smell?
If you've a long companionship with tankless Water Heaters, you must have experienced this at some point in life. A weird smell comes from the Water Heater or the water coming out of the Water Heater. The smell is like the smell of rotten eggs. This is because of the presence of Sulphur in the main water supply. Using such a smelly water for everyday use is a horrible dream so to fix this, you'd have to install a water softener or a water purifier that cleans water from all types of impurities, Sulphur included. But there are cases when the problem persists even after installing the water cleaners. In that case, a relocation of supply lines and a newly dug water supply is the only choice.

Bottom Line:
We just showed you how you can fix numerous problems related to Tankless Water Heaters. There is no denying the fact that professionals are after all professionals but there are things that you can do with utmost precision as easily as professionals do. Just some quick DIY.
