AfterHVAC Company in Dallas, GA
Coldharbour Heating & Air handles AC repair, furnace repair, and AC installation for Dallas homeowners, with most repair calls dispatched same day and a live person answering the phone at (817) 402-2972 around the clock. Dallas sits at a difficult climate crossroads: over 100 days above 90°F each year push cooling systems to near-continuous operation from late April through October, while Gulf-Arctic collision events can drop temperatures below 20°F for sustained stretches. That dual-extreme reality, combined with slab-on-grade construction and aging ductwork through 150°F+ attics, makes Dallas HVAC work genuinely different from what you’d see in Houston, Atlanta, or even nearby Marietta.
Why Dallas Homes Are Different
Dallas and its immediate surrounding area are dominated by slab-on-grade tract homes built from the 1950s through the 1990s, many still running original or first-replacement ductwork through brutally hot attic cavities. The 1970s and 1980s vintage homes are especially common here, and they frequently arrived with undersized or poorly sealed flex duct systems that were never engineered for today’s higher efficiency equipment.
The expansive Blackland Prairie clay soil underlying most of Dallas causes ongoing foundation heave and settlement that physically pulls flex duct boots loose from attic air handlers and register boxes over time. It’s a slow-leak failure mode our technicians find constantly on service calls that counterparts in Houston, with its different Gulf Coast soils, or Austin, sitting on limestone substrate, rarely encounter in the same pattern. February 2021’s Winter Storm Uri exposed another Dallas-specific vulnerability: most systems here were engineered almost exclusively for heat load, leaving homeowners with failed heat pumps and no backup capacity during that sustained multi-day hard freeze. Dual-fuel or properly sized emergency heat capacity isn’t an upsell in Dallas; it’s a necessity.
Our Main Dallas Services
Most calls we get from Dallas homeowners fall into three categories: cooling repair during the long summer run season, heating repair when those Arctic fronts push through, and full system replacement when the combination of age and extreme run-hours finally catches up.
AC Repair in Dallas
AC repair in Dallas means dealing with compressors that have been running five to six months straight and refrigerant lines baking in 150°F attics. We see a lot of capacitor failures, contactor pitting, and low refrigerant charges caused by pinhole leaks in the evaporator coil. Our technicians carry common capacitors, contactors, and refrigerant on every truck, and most repairs are finished in a single visit. AC Repair in Dallas covers what to expect when you call, typical turnaround times, and how our 365-Day Done Right Promise works on cooling repairs.
Furnace Repair in Dallas
Furnace repair here runs the gamut from failed igniters and flame sensors on 90% furnaces to heat exchanger cracks on older units that got pushed hard during Winter Storm Uri. Because Dallas systems must handle both extremes, we often find heat pumps with seized reversing valves or backup electric heat strips that haven’t been tested in years and fail when finally needed. Furnace Repair in Dallas explains our diagnostic process, what we check on every heating call, and when a repair makes sense versus when replacement is the safer play.
AC Installation in Dallas
AC installation in Dallas requires load calculations that account for both the brutal summer attic temperatures and the occasional hard freeze, plus a hard look at whether the existing ductwork can handle modern higher-static equipment. We don’t quote over the phone; every installation starts with a room-by-room load calculation, a duct inspection, and a written fixed price that doesn’t change. AC Installation in Dallas walks through sizing, efficiency ratings, financing, and how we handle the rebate paperwork.

Brands We Service in Dallas
Our technicians are trained to service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common capacitors, contactors, igniters, and refrigerant for Rheem, York, and Bryant systems locally, which means faster turnaround on repair calls for those brands. If we don’t have a part on the truck, our Atlanta office coordinates same-day or next-morning pickup so you’re not waiting through a hot Dallas weekend without cooling.
Pricing for HVAC Company in Dallas, GA
| Service | Typical range in Dallas |
|---|---|

What pushes Dallas jobs toward the higher end: attic ductwork repairs requiring work in 140°F+ conditions, refrigerant leaks requiring EPA-compliant recovery and recharge, and heat exchanger replacements on furnaces where the part cost alone runs high. What keeps them lower: straightforward capacitor or contactor swaps, igniter replacements, and tune-ups where no additional issues surface. Every job gets a written price before any work begins, and that price does not change when the technician is at your door. That’s The Kingswell Way, not a policy we apply case by case.

What Dallas 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."
