How to Avoid Air Conditioning Breakdowns This Summertime



Every year we go on service calls where the air conditioner isn't really cooling and the cause is limited air flow from a very dirty filter. Dirty filters reduce indoor air quality, make the house less comfy, and can result in frozen indoor coils, ultimately leading to major repairs.

Some thermostats need to be changed in between heating mode and cooling mode. Your air conditioner will not start if the switch is in the wrong position or breaks. Quality digital thermostats rarely fail. Some of the inexpensive ones available from the big boxes might. So what fails? The switch might break; a voltage spike may cause a breakdown, and so on.

6. Obstructed Drain Line

Air conditioners pull moisture out of damp air while reducing the temperature level. The moisture is normally drained out of your house through your plumbing system. We clear the drain lines as part of our spring air conditioning tune-up or you can have it done independently, as needed.
