HVAC Company in Loomis, CA
Most HVAC calls in Loomis run $150-$700 for repairs and $3,500-$7,500 for full AC installation, with same-day response available when temperatures spike past 105°F in the foothills. Coldharbour Heating & Air dispatches technicians from our Sacramento coordination office to serve Loomis homes directly, carrying parts for Goodman, Rheem, York, and Daikin systems on every truck. We’re the local, independently operated face of the Kingswell Guarantee, and you can reach us at (817) 402-2972 any hour, any day.
Why Loomis Homes Are Different
Loomis sits in the Sierra Nevada foothill transition zone where summer heat domes push temperatures to 105-110°F, yet winter nights drop into the upper 20s. That dual-load climate kills light-duty equipment designed for Sacramento’s milder swings. We see it every July: aging single-stage AC units on south- and west-facing homes surrounded by open grassland run at 108°F for days straight, and the compressors give out, usually on the weekend when parts are hardest to get.
The housing stock compounds the problem. Most Loomis homes are custom or semi-custom single-story ranches on half-acre to multi-acre lots, many built during the 1970s-1990s expansion with single-speed equipment and ductwork never sized for modern cooling loads. Attic spaces bake in that foothill sun, and the newer estate homes from the 2000s-2010s bring zoning complexity that demands variable-speed systems. Then there’s the fuel question: many large parcels were never piped for natural gas, so propane remains the default heating fuel. When propane prices spike, Loomis homeowners have direct financial motivation to electrify with heat pumps, a conversation we’re always ready to have.
Wildfire smoke corridor exposure adds another layer. After heavy smoke seasons, we field growing calls for whole-house air purification and MERV-13+ filtration upgrades, systems that need proper static-pressure calculations against existing ductwork.
Our Main Loomis Services
These are the three calls we handle most often in Loomis, each with its own dedicated page and local detail.
AC Repair in Loomis
AC repair in Loomis means dealing with heat-damaged capacitors, burnt contactors, and compressor failures triggered by extended 105°F+ runs. We stock hard-start kits and dual-run capacitors sized for the voltage fluctuations that foothill heat creates, and we carry refrigerant rated for the high-ambient conditions these systems face. Our technicians are trained on nine major brands, so the unit in your home, whether it’s a 1990s Goodman or a newer Daikin, gets diagnosed without a return trip for parts. AC Repair in Loomis covers what we fix most, what it costs, and how fast we can get there when the foothills are baking.

Furnace Repair in Loomis
Furnace repair in Loomis splits two ways: propane-fired systems on the large rural parcels without gas mains, and electric heat strips or heat pumps in newer construction. Propane systems need specialized valve and burner cleaning, and the ignition components fail more often where winter moisture settles into foothill valleys. We carry igniters, flame sensors, and control boards for both propane and electric systems, and we check heat exchanger integrity on every call, cracked or not. Furnace Repair in Loomis details common failures, pricing, and what our 365-Day Done Right Promise covers.

AC Installation in Loomis
AC installation in Loomis requires proper load calculation against that dual-load climate, not the simplified square-footage rules that work closer to Sacramento. Undersized ductwork in 1980s ranches needs assessment before any new equipment goes in, and south-facing homes on open lots need higher-capacity condensers with proper defrost cycles for winter heat pump operation. We provide a written fixed price before ordering equipment, handle rebate paperwork where applicable, and schedule installation once the load calc and duct evaluation are complete. AC Installation in Loomis walks through sizing, brands, and what the process looks like start to finish.

What keeps them lower: straightforward capacitor or igniter swaps, both common and both stocked on our trucks. Every job starts with a written price handed to you before any work begins, part of The Kingswell Way. That price does not change at the door.

Absolutely. Many Loomis homes on large parcels never got natural gas service, so propane furnaces and heaters are common in our work.

The 365-Day Done Right Promise applies to propane work exactly as it does to electric or natural gas systems.

What Loomis Customers Say
"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
- Celeste Ngo"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"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
