Every year we go on service calls where the air conditioner isn't really cooling and the cause is restricted air flow from a very unclean filter. Dirty filters minimize indoor air quality, make the house less comfy, and can result in frozen indoor coils, eventually leading to major repair work.

5. Thermostat
Some thermostats need to be changed between heating mode and cooling mode. If the switch is in the wrong position or breaks, your air conditioner won't start. The switch may break; a voltage spike may trigger a breakdown, and so on.
6. Obstructed Drain Line
Air conditioners pull moisture out of humid air while reducing the temperature. The wetness is usually drained pipes from your house through your plumbing system. A drain pan ought to exist as a back up with a secondary condensate drain. Algae can grow in these lines, obstructing them up. This can cause water damage in your house. We clear the drain lines as part of our spring cooling tune-up or you can have it done independently, as needed.
