Questions

Common HVAC questions.

Don't see yours? Call (408) 649-3198 and ask us directly.

My AC is blowing warm air. Can you fix it?

Yes. Warm air usually comes from a dirty filter or coil, a failed capacitor or contactor, a tripped breaker, or low refrigerant from a leak. A technician will find the cause and give you a price before any repair begins.

What does water heater maintenance include?

We flush sediment from the tank, test the temperature and pressure relief valve, inspect the anode rod, check the burner or heating elements, and look over the venting and the gas and water connections.

What is a zoning system and how does it work?

Zoning splits your home into areas that each have their own thermostat. Motorized dampers in the ductwork open and close so the system heats or cools only the rooms that need it, which evens out hot and cold spots.

How often should my dryer vent be cleaned?

Once a year for most households, and more often for large families or long vent runs. Clothes that take longer to dry, a hot laundry room or a burning smell all mean it is due.
