Furnace repair in Garland, TX usually starts with the same discovery: a system that was never sized for the house it’s sitting in. Most of Garland’s housing went up between 1950 and 1980, and a lot of those ranch homes still run original or once-replaced central equipment with low-pitch attics that bake in summer and freeze hard in January. When a cold snap rolls through North Texas, we see heat pumps and older gas furnaces fail in clusters across the city. Sunstone AC Repair has served Garland since 2018, and we work on nine of the most-installed residential HVAC brands rather than pushing one line. Call (866) 970-7959 for a free estimate.
Why Garland Homes Are Different
Garland’s comfort problems start with the attic. The city is full of post-WWII ranch and tract homes, typically pier-and-beam or early slab construction, and many were built with shallow-pitch attics that leave almost no room for a technician to move. In the older neighborhoods around downtown Garland and near the Duck Creek floodplain, we routinely find attic duct runs that have been crushed or pulled loose by roofers and pest control crews working in that tight space. Homeowners usually don’t notice until a July electric bill jumps or a furnace starts pushing warm air into a bedroom that used to be cold.
The second thing is the building envelope. Original single-pane aluminum windows and R-11 attic insulation are still common in Garland, which means load calculations and duct sizing are a real problem, not a formality. Newer Collin County suburbs were built to modern energy codes from day one; Garland homes often need a system retrofitted around what’s already there. Add brutal summers above 100°F, humidity that sits over 60% from May through September, winter freezes that burst outdoor pipes and kill heat pumps, and spring hail that dents condenser coils, and you get a city where the equipment gets worked hard. We plan for that.

Our Main Garland Services
Two calls bring Garland homeowners to us most often: cooling that quits in the middle of summer and heating that quits in the middle of a freeze. Both get the same brand-agnostic diagnosis.
AC Repair in Garland
Cooling repair in Garland is often a duct story as much as a refrigerant story. When a system runs nonstop from May through September in a 1960s ranch house with single-pane windows, the compressor, blower motor, and capacitor all take a beating. We test the equipment first, then check whether the attic ductwork is actually delivering the air it’s supposed to. Hail damage to condenser coils and fan motors is common after spring storms, and that’s a repair we handle on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. For full details on AC Repair in Garland, including what a typical diagnosis involves, see our dedicated page.

AC Installation in Garland
Replacing a system in Garland means doing a real load calculation, because the old unit was likely undersized or the house has changed since it was installed. We look at the attic, insulation, window type, and duct layout before recommending equipment, and we’ll tell you honestly when a repair makes more sense than a new system. Installation is scheduled, not rushed, and every job ends with a written fixed price so there are no surprises. Read more about AC Installation in Garland if you’re weighing a replacement.

Furnace Repair in Garland
Furnace repair in Garland, TX is a winter job with a Texas twist. The 2021 freeze showed how quickly a heat pump or gas furnace can fail when temperatures drop hard and stay there, and Garland’s older ranch homes are especially exposed because outdoor piping and equipment sit in the open. A furnace that limped through a mild December can quit the night it matters. We handle Furnace Repair on the major brands, and because we also repair and install air conditioning, one call covers your whole comfort system instead of two contractors pointing at each other.
What makes a furnace call in Garland different from a call in, say, a newer Collin County subdivision is the housing stock. Pier-and-beam floors, shallow attics, and original ductwork mean heat loss and airflow problems that a simple part swap won’t fix. We diagnose the equipment, then check whether the ducts and returns are actually moving warm air where it needs to go.
Gas Furnace Repair
Signs you need it
You smell gas near the unit, the burners light and then shut off within seconds, the blower runs but the air stays cool, or the furnace short-cycles through a cold night.
What it costs in Garland
Gas furnace repair in Garland typically falls in the $150 – $700 range, and the written estimate sets the final price.
How we do it
We shut down the unit, test the igniter, flame sensor, gas valve, and heat exchanger, then confirm draft and venting before we replace anything.
Heat Pump Repair
Signs you need it
The system blows cool air in heat mode, the outdoor unit ices over and stays that way, or the aux heat strips run constantly and your electric bill spikes.
What it costs in Garland
Heat pump repair in Garland is typically $150 – $700 depending on the failed component, with the written estimate setting the final price.
How we do it
We check the reversing valve, defrost board, refrigerant charge, and backup heat, then test the system in both modes before we call it done.

What Garland Customers Say
"Ductwork in the attic had a disconnected run that had been dumping cold air into the insulation for who knows how long. He found it, resealed it, and one bedroom that was always hot is now normal."
- Alma Martinez"Blower motor on a 12 year old furnace. He gave me the honest math on repair versus replace and did not push me toward the bigger ticket. We repaired it and it's been fine."
- Tara Doyle"Contactor was pitted and chattering. Cheap part, quick fix, and he showed me the burn on the old one so I could see for myself."
