How to keep your ac running strong
Have your unit serviced regularly.
One of the best things you can do to ensure that your air conditioner remains functional is to have the unit serviced on a regular basis. Regular service is important, because it will keep the unit performing optimally.
Also, service and repair should always be performed by a licensed technician. Performing maintenance on your own could lead to more severe problems, and could void any existing warranties on the unit.
