A Little Spring Cleaning Will Make the A/C Happy!
Aside from your system's air filtration needs, an excellent way to improve the performance and reliability of the A/C is to wash the condenser coil with a good spray of water. When a neglected coil is cleaned, your air conditioner can more easily reject heat it removes from the air in the house. A cooling capacity increase of 10% is not unusual, and electrical consumption will decrease as well.
