AfterHVAC Company in Haslet, TX
Most HVAC calls in Haslet involve systems that are 5 to 15 years old, right when builder-grade equipment starts failing and improper original installation reveals itself. We’re Coldharbour Heating & Air, and our technicians see the same patterns across Haslet’s newer subdivisions: oversized condensers, undersized returns, and ductwork that wasn’t sealed properly the first time. If your AC is blowing warm air in July or your furnace quit on a February morning, call us at (817) 402-2972. A live person answers 24 hours a day, and we’ll give you a firm arrival window, not a four-hour guess.
Our Main Haslet Services
Haslet homeowners call us most often for cooling repairs in summer and heating repairs after the first hard freeze. Each job follows The Kingswell Way: written price first, written guarantee last.
AC Repair in Haslet
Haslet’s unshaded new subdivisions and 140°F+ attic temperatures cook capacitors and compressors faster than the manufacturer expected. We carry common Goodman and Rheem parts on every truck, and most AC Repair in Haslet calls finish same day. Our technicians check refrigerant charge, test the TXV (the valve that meters cooling fluid), and measure static pressure to spot the duct problems that come standard in too many local builds.
Furnace Repair in Haslet
The February 2021 freeze cracked condensate lines and killed defrost boards across Haslet’s newer housing stock, and we still find homes where the original installer never winterized the auxiliary heat kit properly. When you book Furnace Repair in Haslet, we test every heat stage, inspect the heat exchanger for cracks, and verify gas pressure to the burner. No heat is an emergency in North Texas ice, and we treat it that way.
AC Installation in Haslet
Because so many Haslet homes were built with oversized equipment and undersized returns, a proper AC Installation in Haslet starts with a Manual J load calculation, not a square-footage guess. We size the system to the actual heat gain of your specific home, upgrade return ductwork when needed, and hand you a written fixed price before we order equipment. Most installs schedule within a week once you approve the quote.

Why Haslet Homes Are Different
Haslet transformed from a rural Tarrant County crossroads to a booming DFW suburb almost entirely after 2010. That means the housing stock is dominated by large brick-veneer tract homes, 2,200 to 4,000+ square feet, built by volume builders like D.R. Horton and LGI along the I-35W corridor. These houses sit on post-tension concrete slabs with attic-mounted air handlers in unconditioned spaces that bake all summer.
The prairie terrain here offers almost no tree canopy on newer lots, so western sun hits those brick walls full force. North Texas summers now regularly top 105°F, and systems run near-continuously for months. The February 2021 Winter Storm Uri exposed how poorly prepared this new construction was for real cold, with cracked condensate drains and failed defrost boards still showing up in our diagnostics.
Here’s what makes the work predictable: entire streets were built by the same contractor with the same plans. When we find a single 20×20 return choking a 3,500 square foot home on one lot, we know the next six doors down have the identical static pressure problem. That pattern recognition saves our customers time and money.

FAQs About HVAC Company in Haslet
Most Haslet calls schedule same day if you call before early afternoon. Emergency no-heat and no-cooling calls get priority routing, and our Dallas-Fort Worth dispatch keeps trucks staged for 30-to-45-minute arrival across the city. Call (817) 402-2972 and a live person will give you a firm window, not a vague “sometime today.”
Some Sendera Ranch and newer subdivision HOAs require notification for outdoor unit replacements or pad modifications, but standard repairs rarely need HOA approval. We handle permit pulls with the City of Haslet when a full system replacement requires inspection, and we build that time into your written schedule so you’re not chasing paperwork.
Volume builders in the 2010s-2020s growth surge often prioritized speed over precision. We see oversized condensers that short-cycle, single returns choking airflow in 3,500 square foot homes, and ductwork that was never properly sealed. These aren’t age problems, they’re installation problems, and they’re fixable with proper load calculations and duct upgrades.

What Haslet Customers Say
"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"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."
