HVAC Company in Fresno, CA
Coldharbour Heating & Air is an independently owned HVAC company serving Fresno with AC repair, furnace repair, and AC installation. Our dispatch and scheduling are coordinated from our Fresno, Central Valley office, with crews working locally throughout the metro area. The San Joaquin Valley’s extreme heat and poor air quality create conditions here that shorten equipment lifespans and accelerate maintenance needs compared to nearly anywhere else in California. Call us at (817) 402-2972 for a free estimate.
Why Fresno Homes Are Different
Fresno sits at the floor of the San Joaquin Valley heat trap, enduring 70+ days above 100°F annually, often sustaining 105-110°F stretches for weeks at a time. The valley’s thermal inversion layer traps agricultural dust, wildfire smoke, and haze against the valley floor, so outdoor condensers routinely reject heat into air that is itself 105°F+ for sustained periods. This pushes refrigerant head pressures beyond what equipment manufacturers engineer for in milder California markets.
Central and west Fresno contain large swaths of 1950s-1970s tract homes, many with original duct systems routed through unconditioned attics that reach 150°F+ in summer. That heat strips 25-35% of cooling capacity before air ever reaches a register. North Fresno absorbed rapid suburban buildout in the 1990s-2000s, meaning a distinct cohort of gas-pack and split systems in that corridor is now hitting the 20-to-25-year replacement window simultaneously.
During almond, cotton, and grape harvest season, roughly August through October, agricultural dust surges dramatically. We regularly pull evaporator coils completely caked within four to six weeks of a service call. Standard 1-inch filters that would last three months on the coast are effectively useless after three to four weeks here. Winter brings the notorious Tule fog, dense radiation fog that keeps outdoor heat-pump and condenser units in near-constant saturated moisture for weeks, accelerating cabinet and contact corrosion.
Our Main Fresno Services
These are the three services Fresno homeowners call us about most often, each with its own dedicated page for detailed information and pricing.
AC Repair in Fresno
When an AC system fails during a Fresno summer, the indoor temperature can climb past 90°F within hours. Our technicians carry common capacitors, contactors, and refrigerant to restore cooling the same day on most calls. We see a high volume of dirty evaporator coils and failed capacitors during harvest season dust surges, and we stock filters rated for the particulate load this valley produces. AC Repair in Fresno covers our full diagnostic process, common failure patterns, and what same-day repair looks like in your neighborhood.

Furnace Repair in Fresno
Fresno winters are mild compared to mountain markets, but the Tule fog creates unique problems for gas furnaces and heat pumps alike. Ignition failures, flame-sensor corrosion, and heat-exchanger cracks from short-cycling are the calls we handle most when temperatures drop into the 30s. We inspect the full combustion sequence and test for carbon monoxide on every furnace repair. Furnace Repair in Fresno explains our winter service process and what we check before declaring a system safe to run.

AC Installation in Fresno
Installing a new system in Fresno requires sizing for heat-load conditions that exceed standard Manual J assumptions for California. We measure duct losses in 150°F attics, specify condensers rated for high-ambient operation, and seal every joint with mastic, not tape that will cook off. Our install crews handle permit paperwork with the City of Fresno and coordinate inspections so you are not chasing permits yourself. AC Installation in Fresno walks through load calculation, equipment selection, and what a typical replacement timeline looks like.

FAQs About HVAC Company in Fresno
During summer peak, our live dispatchers aim to have a technician to your door the same day you call. We answer the phone 24 hours a day, 7 days a week, and we do not route after-hours calls to voicemail. For non-emergency scheduling, we offer firm arrival windows, not all-day waits. Call (817) 402-2972 to check today’s availability.
Yes, the City of Fresno requires a permit for any new AC installation or furnace replacement. We pull the permit as part of our standard installation process and coordinate the required inspection so you do not need to visit the permit office yourself. This is included in our installation quote, not added later.
Running AC during wildfire smoke or heavy agricultural dust is safe if your system has a clean filter and the outdoor condenser is not clogged. We recommend checking your filter monthly during harvest season and upgrading to a pleated filter with a higher MERV rating if you have respiratory sensitivities. If your system is pulling in smoke or smells, call us to inspect the return air path and filter seal.

What Fresno 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
