Frequently Asked Questions

Do you offer same-day furnace repair in San Rafael?

Yes — our trucks are stocked with common furnace parts, so when you call early we can usually dispatch a licensed technician to San Rafael the same day, including emergency no-heat calls.

How much does furnace service or a diagnostic cost?

Our furnace diagnostic starts at a flat $67, and estimates for a new furnace installation are always free, so you know the price before any work begins.

When is furnace installation in San Rafael worth it instead of another repair?

Once a furnace passes 15-20 years and repairs start stacking up — or the heat exchanger cracks — furnace replacement usually pays off in lower PG&E bills, and we’ll walk you through high-efficiency and heat-pump options that qualify for local rebates.

Can you convert my older gas furnace to a heat pump?

Absolutely. Many San Rafael homeowners are going electric, and as a licensed (CA #501853) contractor we size and install heat pumps that work with your existing ductwork and capture available BayREN and TECH Clean California incentives.

Can leaking ductwork cause my furnace to run constantly?

Yes. Because of the heat loss, your home will not warm up at the rate that it should, meaning your heating installation will have to work harder and run longer to try to reach the desired temperature.

Why is my furnace blowing cold air?

A furnace installation blowing cold air can mean you have a clogged air filter, there is a problem with the ignition process, or the thermostat is set incorrectly.

Why is my furnace running but my house isn’t getting warm?

Common reasons for this include leaking ducts, a clogged air filter, or a blocked or closed vent that is not allowing the heat to reach the rooms in your home.

Why is my furnace making a banging or rattling noise?

Rattling and banging noises specifically indicate a loose part in the system or a damaged blower motor. You should call for heater repair in this case.

Why does my furnace smell when I turn it on?

An initial burning smell can be from dust burning as the furnace turns on and should not last long. If a burning plastic smell or rotten egg odor is persisting, this can mean an electrical part is melting or there is a gas issue that needs to be treated immediately.
