If you installed an outdoor air-conditioning unit yourself, but it doesn't cool the house properly, you may wonder whether you did something wrong during the installation. Although it's possible to install an AC unit without a professional's help, you can easily make mistakes along the way. One of the mistakes you might make is installing the unit in a place with very little airflow, stability, and room. You can do the following things to correct the problem.
Create Space Around the Unit
Outdoor condenser units require sufficient space, or clearance, to operate properly during the summer season. Sources recommend placing a unit about two feet away from structures such as walls and plants. This distance allows your unit to expel heated air as well as pull in cool air.
You can check the space between your unit and the structures close to it with a yardstick or tape measure. If the clearance area is less than two feet, move the unit to create the additional space it needs. Be cautious during this step, as you can easily dislodge or pull loose the wires and pipes connecting the outdoor unit to the indoor unit.
After you reposition the outdoor unit, check your home to see whether it feels cooler. If it does, you have solved the problem. If your home still feels warm, you can try to fix the issue with the next step below.
Stabilize the Unit
If you didn't install your unit on a concrete or plastic pad, the unit can lean and block airflow through the condenser coil. Padding also keeps dirt and grass from entering the bottom and sides of the unit. These things can cover or grow on the unit's condenser coil and prevent it from moving heat. The heat may back up into the compressor motor and damage it.
To solve the problem above, have someone help you place the unit on a sturdy pad. If you can't find or use a concrete pad, purchase a plastic pad from your local home and gardening store. The pad should be strong enough to support the weight of your unit and sound enough to not sink into the ground. If you have problems selecting the right pad, contact an AC contractor for assistance. Placing the unit on the wrong type of pad may cause it to tilt or sink in the future.
