Central AC repair in Costa Mesa: questions
Which Costa Mesa ZIP codes are covered?
92626 and 92627.
What does a capacitor do?
It gives the compressor and fan motors the boost they need to start and run. Capacitors weaken with heat and age and are one of the most common AC repairs.
Why is there water around my furnace?
Cooling produces condensate that drains through a line, often to the outside or a drain. A clogged line, cracked pan or failed condensate pump causes overflow.
