HVAC Company in Murrieta, CA
Coldharbour Heating & Air dispatches technicians from our Inland Empire office to handle AC repair, furnace repair, and AC installation across Murrieta’s master-planned communities. Most calls we get here involve 15-25 year old builder-grade systems originally installed during the late-1990s through mid-2000s housing boom, now failing in pairs as compressors, capacitors, and igniters give out under dual summer heat and winter chill. If your system is down or you’re planning replacement, call us at (817) 402-2972 for a free estimate.
Why Murrieta Homes Are Different
Murrieta sits in an inland valley at roughly 1,000-1,100 feet elevation, more than 30 miles from the Pacific with no reliable marine layer. Summer highs routinely hit 100-107°F from June through September, while winter nights regularly drop into the low-to-mid 30s. That dual demand pattern forces HVAC systems to work hard year-round, a stress load coastal San Diego communities simply don’t face.
Nearly all residential construction here dates to 1997-2008: large two-story stucco tract homes of 2,200-3,500 square feet in communities like Greer Ranch, Spencer’s Crossing, and Bear Creek. Ductwork almost universally runs through unconditioned attics that exceed 140-150°F in summer, accelerating equipment wear and bleeding efficiency. We’ve measured supply air losing 8-12 degrees before it ever reaches a bedroom vent.
The Santa Ana wind events peak September through November, driving dust and chaparral debris straight into hillside condensing units. We see a predictable surge of emergency no-cool calls in October, right when homeowners assume cooling season is finished and stop checking their outdoor units.
Our Main Murrieta Services
These are the three calls we handle most often in Murrieta. Each links to its dedicated local page with deeper detail on that service.
AC Repair in Murrieta
Most summer calls from Murrieta start the same way: the thermostat’s set to 72, the house is pushing 85, and the condenser outside is either silent or humming without the fan turning. We carry capacitors, contactors, and refrigerant on every truck, and we stock coils and compressors sized for the 3.5-5 ton systems common in Murrieta’s larger homes. Because attics here run so hot, we also check duct integrity on every no-cool call; a sealed leak can recover more comfort than a harder-working compressor. AC Repair in Murrieta

Furnace Repair in Murrieta
Winter nights in the low 30s put real load on gas furnaces that sat idle for eight months. We see cracked heat exchangers in 20-year-old Goodman and Rheem units, failed igniters on York systems, and limit switches tripping from restricted airflow caused by dust drawn through attic returns. Every furnace repair includes combustion analysis and a written safety check before we leave. Furnace Repair in Murrieta

AC Installation in Murrieta
With Murrieta’s housing stock hitting simultaneous end-of-life, we’re replacing full systems weekly in Greer Ranch, Mapleton, and the older sections of Bear Creek. Every install starts with a Manual J load calculation (measuring exactly how much cooling and heating your specific home requires), followed by duct inspection and a written fixed price. We handle permit paperwork with the City of Murrieta and coordinate HOA notifications for communities that require them. AC Installation in Murrieta

What Murrieta Customers Say
"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
- Natalie Esposito"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
- Marcus Reilly
