Clean the fan blades and coils on the condenser fan every spring. Before you do anything, however, turn the power off. Secondly, pop the grill off, take the blades off and clean them as well as the actual unit.

Cover your unit when you are mowing the lawn. Make certain the debris goes away from it. This applies when you are taking care of the leaves in the yard.

Check to determine if the fan condenser on your HVAC system is equipped with oil ports, and if it is, be sure to lubricate every year. Such ports tend to have coverings made of rubber or metal. Pick out a SAE 20 type of oil because it has no detergent, is lightweight, and you should put around 10 drops in the ports but make it to where they don’t get too full.

If you want to know where you should put an outdoor compressor, you should place it somewhere where there is a lot of shade. If you have a unit taking in air that’s cooler, it won’t have to work so hard to cool air that it sends to your home.

When it gets cold outside, turn off the outdoor condensers. When the temperature goes below 60 degrees, shut off the unit in order to prevent damage. Your system will work longer for you this way.

To help lower cooling costs when not at home, make sure the air conditioner is turned off. The house will heat up, but not too much. Obviously, if you leave your air conditioning set at a low temperature all day long even if you’re not home, you’ll be paying to maintain that low temperature.

Do not allow your house to get extremely hot. Expect an air conditioning unit to drop the temperature down 20 degrees within a short amount of time. If the temperature in your home reaches 100 degree Fahrenheit, it will only reduce it to 80 or more. Depending on humidity levels, this isn’t even a safe temperature for a human body to sleep at to recover from summer heat.
