To many people, shutting off the Air Conditioner means unplugging the switch and covering the outside condenser unit. While this is a layman approach towards a heavy duty HVAC system like the Air Conditioner, the professional's approach is all the way different. Since we know little about the heating and cooling system, we should rather rely on professional's advice. So here we bring to you; the professional's recommended way of switching off the Air Conditioner for the season. 

1. What you already do - Switch off!!!

You already switch off. So yes, begin by switching off the unit. In the case it is a Central Air Conditioner, switch off first from the Thermostat and later, disconnect the power supply to the condenser unit from the electrical box located close to it. Switch it to ''off'' position.

2. What you don't (usually) do - Clean filter at the end of season

A lot many people, as the summer ends, forget about changing the filter, not realizing the fact that the same duct work would be used to blow warm air in winters. As a result, the filters are usually very dirty when the Furnace is turned on for the first time in winters. From now on; add this to-do of cleaning/replacing filters at the end of summer in your list. 

3. Let the indoor breathe fresh

Nature has its own way to take us through different seasons. You don't have an abrupt change in seasons. They are very subtle and serene. And this is why, as the summer ends, there is a period of moderate weather that neither requires Air Conditioner nor Furnace. And that is the time when you should allow your indoor to breathe fresh air. Some homeowners continue to use Air Conditioners until they see the first blow of Winter (a little exaggeration). This practice results in a very contaminated indoor. Since the indoor does not get sufficient fresh air and becomes more polluted than the outdoor air. So make the most use of the moderate weather period after summers and use only fans if needed. Keep the windows open and let fresh air circulate.

4. Clean the outdoor condenser unit thoroughly

It is recommended to clean the unit before starting using it but the same is recommended as you bid good bye to your unit. First remove the leaves, dust and debris from the unit using a fine brush. A low pressure vacuum will do as well. After that, use a hose to clean the unit with plain water. During this course of action, if any damage to the unit is inspected, get it repaired instantly instead of postponing it for the next summer. This is because the problem might worsen over time.

5. Cover the condenser unit 

One confusion that homeowners face is whether or not to cover the condenser unit. Some say not covering the unit makes it a home to pests and animals. While others say that covering their unit results in excessive moisture accumulation and eventually causing the unit to rust. So what to do?
The right way is to cover the unit but not just with any cloth. Cover it with insulated covers manufactured specifically for the condenser units. If you wish to keep it cheaper, use vinyl tarp waterproof plastic to cover the unit. Use elastic cords to hold it tight around the unit.

The advice of all advices if to provide your unit with proper maintenance throughout the season. The wise homeowners, even at the end of summer, call a maintenance tech to ensure that they are closing the system with no sickness. Make sure you do the same this time.
