AfterHVAC Company in Wilmer, TX
Dalton Heating & Air handles heating and cooling work across Wilmer, TX with written pricing, a live person on the phone around the clock, and a full-year written guarantee on every repair. Wilmer sits in southern Dallas County along I-45, where summers run long and the housing stock ranges from 1970s brick ranch homes to newer developments. That mix means we see everything from aging Goodman condensers to recently installed Daikin heat pumps. When your system fails in August or January, call (361) 306-9515 and a real person answers.
Why Wilmer Homes Are Different
Wilmer’s location along the Trinity River corridor brings real humidity through the cooling season. That moisture forces AC systems to pull more latent heat out of the air, which wears down capacitors and contactors faster than in drier parts of the metroplex. Homes along East Belt Line Road and down toward the Wilmer-Hutchins line tend to be older, with tighter mechanical closets and duct runs that were designed for smaller systems. We regularly see units in Wilmer where someone added on a room or enclosed a garage without resetting the static pressure, and the blower motor has been running hot ever since.
The newer subdivisions south of town near the I-45 frontage have a different profile: builder-grade equipment installed fast, with filter driers skipped and line sets run long. Neither setup is wrong, but each responds differently to repair work. We carry parts for both profiles on the truck, so a diagnostic visit usually ends with the system running the same day.
Our Main Wilmer Services
The two calls we take most from Wilmer homeowners are AC failures in the summer and furnace problems in the winter. Heat pump installation has grown steadily as more homes in the area move toward all-electric systems. Each service has its own page with full pricing and details.
AC Repair in Wilmer
When a condenser sits in full Texas sun off a concrete pad near the back fence, the run capacitor and contactor take the brunt of it. We diagnose the exact fault, put the repair price in writing before any work starts, and finish most calls in a single visit. If your system is low on refrigerant, we find the leak before we top it off – refrigerant recharge, meaning topping off the cooling fluid your system needs to reach set temperature, only makes sense once the leak is sealed. See the full breakdown at AC Repair in Wilmer.
Heat Pump Installation in Wilmer
A heat pump heats and cools from one outdoor unit, which fits Wilmer homes where gas lines were never run or where the furnace room is too tight for a full split system. Installation here means sizing the unit to the home’s actual load, not just swapping in the same tonnage the builder used. We replace the indoor air handler and the outdoor condenser together, set the charge by subcooling, and hand over the written warranty before we leave. Details are on the Heat Pump Installation in Wilmer page.
Furnace Repair in Wilmer
Wilmer’s winters are short but they dip hard enough to freeze pipes in a weekend. A furnace that won’t light is usually a failed igniter or a dirty flame sensor, both of which we carry on the truck. The repair is guaranteed in writing for a full year; if it fails in that time, we return at no charge. For gas furnaces we also check the heat exchanger and flue draft on every call, because a cracked exchanger is a carbon monoxide risk, not a comfort issue. Full scope at Furnace Repair in Wilmer.

Pricing for HVAC Company in Wilmer, TX
| Service | Typical range in Wilmer |
|---|---|
| AC repair | $150 – $650 |
| Furnace repair | $150 – $700 |
| AC installation | $3,500 – $7,500 |
| Preventive tune-up | $80 – $200 |
What pushes a Wilmer job toward the higher end of these ranges is usually access and system age. A condenser squeezed into a side yard with an overgrown hedge takes longer to service, and a 20-year-old system with corroded wiring often needs more than one part. Whatever the number is, you get it in writing before we start, and the price does not change at the door. That is the Garrison Standard, and it is not optional.
