AC Repair and Maintenance
A broken AC or furnace is a major inconvenience.

Furnace Services in Walnut Creek
Walnut Creek winters easily drop into the 30s on cold nights, and a furnace not firing up right on a January morning goes way past just an inconvenience. Our team keeps your heating system safe, efficient, and ready when you need it.
Gas Furnace Repair
Most Walnut Creek homes run on gas furnaces, and most of our heating calls are repairs. We troubleshoot ignition failures, airflow problems, blower motor issues, and gas safety concerns, then fix them. Check out our Walnut Creek gas furnace repair page for more.
Heating Repair and Maintenance
Annual maintenance keeps ahead of worn parts, dirty burners, and safety issues. Learn more on our heating repair and maintenance page.
Heating Installation and Replacement
If your furnace is past 15 or so years, it’s probably time for a replacement, especially if you’re noticing lower perfromance and frequent repairs. If you need a replacement, we install high-efficiency furnaces sized correctly for your home.
Boiler Services in Walnut Creek
Plenty of older Walnut Creek homes still run on boiler systems for heat and hot water. We’re one of the few local contractors licensed for boiler work.
Boiler Repair, Maintenance, and Installation
We handle the full range of boiler work: diagnostics on a unit that won’t fire, preventative maintenance to keep efficiency up, and replacement when it finally reaches the end of its lifespan.
Commercial HVAC in Walnut Creek
We also handle commercial HVAC for offices, retail, and multi-unit properties across Walnut Creek.

Walnut Creek HVAC FAQs
How much does HVAC service cost in Walnut Creek?
That depends on what’s wrong and what unit you have. A minor repair (like a capacitor or thermostat) will be much less than something bigger like a blower motor or compressor replacement. We don’t like to give quotes blind on the phone, so give us a call and we’ll come out and see what the issue is. Then we’ll give you a qupte so you know exactly what needs to be done and how much it’ll cost.
How often should I have my AC and furnace serviced?
Shoot for once a year; that’s the standard. Your AC in early spring before the heat sets in, and in the fall before winter for your furnace. When you get these tune-ups, you’re allowing yourself to catch any expensive problems before they rear their ugly heads. You’ll end up saving bills, keeping your system lasting longer, and retaining manufacturer warranties.
My AC is running but the house isn’t cooling. What’s wrong?
This is one of the most common calls we get in the Bay Area. It’s usually one of four things: low refrigerant from a leak, a dirty or blocked condenser coil, a failing compressor, or a thermostat that’s not reading correctly. Some of these are quick fixes and some are major repairs. Call us, we’ll come out to look, and let you know what’s going on.
