San Lorenzo HVAC Questions & Answers

How much does AC repair in San Lorenzo cost?

My AC is not blowing cold air in San Lorenzo. What should I check first?
Check three things: the air filter, since a clogged filter chokes airflow; the outdoor unit, clearing debris and confirming the fan spins; and the breaker. If the indoor coil is iced over, set the system to FAN ONLY for one to two hours to thaw, then call us, because ice means low refrigerant or restricted airflow.
I have no heat in San Lorenzo. Is that an emergency?
If indoor temperatures are falling below the mid 50s Fahrenheit, or there are infants, seniors or anyone with a medical condition in the home, treat it as an emergency. We run 24 hour heating repair in San Lorenzo year-round. If you smell gas, leave the house first, call your gas utility, then call us.
Do you repair heat pumps in San Lorenzo?
Yes. Heat pump repair in San Lorenzo covers reversing valves, defrost boards, low charge, auxiliary heat strips, inverter mini-splits and cold-climate heat pumps.
Why is my furnace short cycling in San Lorenzo?
The most common causes are a dirty filter, a failing flame sensor, a blocked flue or a limit switch tripping from overheating. Short cycling wastes energy and can crack a heat exchanger, so it should be diagnosed quickly.
Do you offer AC tune-ups and furnace tune-ups in San Lorenzo?
Yes. Seasonal maintenance is the cheapest HVAC you will ever buy. An AC tune-up in spring and a furnace tune-up in fall prevents the majority of emergency breakdowns we see in San Lorenzo.
Are you licensed and insured?
Yes. Licensed, insured, EPA 608 certified and background-checked, with permits pulled where required.
Which brands do you service in San Lorenzo?
