HVAC Company in Selma, TX
Most HVAC calls we get from Selma aren’t simple fixes. They’re repeat no-cooling calls driven by vineyard dust choking systems that were already working overtime in 105°F heat. Coldharbour Heating & Air dispatches technicians who understand the San Joaquin Valley’s particular strain on equipment: particulate-laden air, original ductwork from the 1970s, and the temperature swings that come with life on the valley floor. Our 365-Day Done Right Promise applies to every repair we make in Selma, and a live person answers our phones at (817) 402-2972 around the clock.
Why Selma Homes Are Different
Selma sits on the flat floor of the San Joaquin Valley, where summer highs regularly exceed 105°F for weeks at a stretch and the region consistently ranks among the worst in the nation for PM2.5 air quality year-round. That combination forces HVAC equipment to run at maximum capacity while simultaneously choking on particulate-laden air. Winter brings heavy Tule fog that keeps nighttime temperatures near freezing for extended periods, creating heating demand often underestimated in such a hot-summer market.
The housing stock tells the rest of the story. Most Selma homes are modest single-family builds from the 1950s through the early 1990s, many still running original undersized duct systems or only partially upgraded from evaporative cooling to refrigerated central air. Older attic-mounted units with flex duct are common, and insulation levels in the older slab-on-grade homes frequently can’t handle the valley’s extreme temperature swings. From mid-August through September, when raisin drying operations peak, technicians working homes on Selma’s south and east edges routinely pull filters completely loaded with fine vineyard dust within three to four weeks of installation. That failure cycle drives compressor strain we simply don’t see in Fresno’s urban core twelve miles north.
Our Main Selma Services
These are the three services Selma homeowners call us for most often. Each has its own dedicated page with deeper detail on local conditions and pricing.
AC Repair in Selma
AC repair in Selma usually starts with a no-cooling call during August or September, when vineyard dust has clogged the condenser coils and the system’s been running sixteen hours a day. We check refrigerant pressure (the cooling fluid level), test the capacitor (the electrical component that starts the compressor), and inspect the condensate drain for algae buildup common in valley humidity. Most repairs run $150-$650. Our technician will hand you a written price before any work begins, and every repair carries our 365-Day Done Right Promise. AC Repair in Selma has full details on common failures and what to expect.

Furnace Repair in Selma
Furnace repair in Selma catches some homeowners off guard. They moved here for the heat and didn’t expect Tule fog nights to drop into the high twenties. We see cracked heat exchangers in older units, failed igniters on furnaces that sat idle ten months, and limit switches tripped by restricted airflow from dust-packed filters. Most furnace repairs run $150-$700. Before we start, you’ll get a written price that won’t change, and the work is covered for 365 days. Furnace Repair in Selma covers what fails and when to repair versus replace.

AC Installation in Selma
AC installation in Selma requires load calculation that accounts for more than square footage. The particulate load, the intensity of the cooling season, and the condition of existing ductwork all affect sizing and equipment selection. We don’t promise same-day installation; that work is measured, ordered, and scheduled with a firm date. Most new systems run $3,500-$7,500, and we handle rebate and financing paperwork. AC Installation in Selma explains the process and what to budget.

What pushes Selma jobs toward the higher end: vineyard dust damage requiring coil deep-cleaning or compressor replacement, ductwork modifications for systems never properly upgraded from evaporative cooling, and after-hours emergency calls during peak harvest heat. What keeps them lower: straightforward capacitor or contactor replacements, igniter swaps, and scheduled maintenance visits. Either way, the written price we hand you before any work begins is the price you pay. That’s The Kingswell Way, and it’s non-negotiable.

What Selma Customers Say
"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"Furnace wouldn't light the first cold morning. The guy walked me through what he was checking so I actually understood it. Replaced the igniter, wrote up the warranty, and it's been warm since."
- Alicia Romero"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."
