Dalton Heating & Air is the HVAC company Garland homeowners call when a system fails in July or a furnace won’t light on the first cold morning of December. Most of the homes we work on were built between 1960 and 1985, with original ductwork, slab foundations, and equipment that has been patched together for years. That combination of age, Dallas heat, and deferred maintenance means repair calls here are rarely simple. When you call (254) 280-5320, a real person answers and schedules a background-checked technician who arrives inside the stated window with the price in writing before any work begins.
Why Garland Homes Are Different
Garland’s housing stock tells the story of how this city grew. The neighborhoods around Downtown Garland, Duck Creek, and Springpark are full of 1960s and 1970s ranch homes, many still sitting on their original galvanized ductwork. That duct is corroded, leaking, and rarely sized correctly for modern AC systems. We regularly find homes where the return air side is undersized, which makes the blower motor work harder and fail earlier than it should. Add in slab-on-grade construction, and you get evaporator coils that run hot, refrigerant lines that are hard to access, and repairs that take longer than they would in a newer two-story with a proper mechanical closet. None of this is the homeowner’s fault – it’s just what 50-year-old construction looks like in Garland.
The climate compounds all of it. Garland sees stretches of 100°F-plus days from June through September, and AC systems run for months without a break. Capacitors fail, compressors overheat, and condenser coils clog with cottonwood and oak pollen every spring. Winters are milder but unpredictable, and we see the same pattern every year: a furnace that was never serviced sits idle for eight months, then fails on the first night temperatures drop below freezing. The rental market here makes it worse. A large share of Garland’s single-family homes are rentals with deferred maintenance, which means tenants wait longer to report problems and landlords push equipment past its useful life. By the time we’re called, the repair is often an emergency.
Styles & brands we work with
Our Main Garland Services
Garland homeowners call us most often for two reasons: an air conditioner that quit working in the middle of a hot stretch, or a furnace that won’t start when the season turns. Here is what each job involves locally.
AC Repair in Garland
Most Garland AC failures come down to three things: a failed capacitor, a refrigerant leak from an aging evaporator coil, or a compressor that finally gave out after years of 100-degree days. In older ranches near Downtown Garland, we still find R-22 systems in service, and those are often one clogged condenser coil away from a burnout. Our technicians diagnose the exact fault before recommending any work, and the repair price is written down before we touch the equipment. If you need AC Repair in Garland, we’ll give you the number, the part, and the arrival window up front.
Heat Pump Installation in Garland
Heat pumps make sense for Garland homes with no gas line, or for homeowners replacing an aging R-22 system and wanting something more efficient than straight electric heat. The installation is more involved than a simple AC swap – the system has to handle both cooling and heating loads, and the existing ductwork has to be evaluated. We walk homeowners through load calculation, equipment selection, and the full written price before any materials are ordered. For a fixed quote on Heat Pump Installation in Garland, call us and we’ll set an install date at the same time we hand you the price.
Furnace Repair in Garland
Garland furnaces fail differently than the AC side. The heating season is short, so many homeowners skip tune-ups and the first cold snap exposes problems that have been building for years: cracked heat exchangers in aging gas furnaces, blower motors worn out from oversize AC duty, or control boards failing after years of garage heat. We service natural gas and electric furnaces and stock common parts locally, which keeps turnaround faster during the December rush. For Furnace Repair in Garland, we diagnose the fault, quote the repair in writing, and stand behind it for a full year.
Both services run on the same terms: a live person answers the phone around the clock, a uniformed technician shows up inside the window, and the price is in writing before any work starts. That is the Garrison Standard, and it applies on every job without exception.

Most AC and furnace replacements in Garland require a city permit, and licensed installers pull it as part of the job. We handle the paperwork and coordinate inspections. Repairs generally do not need a permit, but we’ll tell you at the estimate if your job does.
Some Garland neighborhoods have deed restrictions on where the condenser can sit, usually screened from street view. We’ll work with whatever your HOA requires. The best step is to pull your HOA guidelines before installation day, and we’ll route the equipment accordingly. We’ll confirm the details at the written estimate so there are no surprises on install day.
