Furnace repair in Richardson matters more than most homeowners expect from a North Texas suburb. The 1960s and 70s ranch homes built for the Texas Instruments-era workforce in 75080 and 75081 were designed when winter heating was an afterthought, and decades later those systems still struggle through the hard freezes that occasionally roll through. Cooling gets all the attention here, but a furnace that quits in January is a genuine emergency. We’re Sunstone AC Repair, and we work on both sides of your system so you don’t need two contractors. Call (866) 970-7959 for a free estimate.
Why Richardson Homes Are Different
Richardson’s HVAC story is shaped by the Telecom Corridor. Block after block of ranch homes in 75080 and 75081 went up for the Texas Instruments-era workforce, and most of those houses are now at or past the age where original ductwork, undersized electrical panels, and first- or second-generation AC systems need full replacement rather than patching. Many owners are the second or third occupant of the same house, inheriting equipment nobody has documented.
The housing stock splits cleanly. The older core is mostly single-story brick ranches and small tract homes. Toward 75082, near CityLine and the President George Bush Turnpike, you find newer two-story subdivisions and townhomes with tighter envelopes and builder-grade systems still under or just past warranty. The older stock carries the harder problems: original attic ductwork with low R-value insulation, single-pane windows, and 100-150A panels that complicate heat pump or variable-speed upgrades. North Texas summers push past 100°F with high humidity, so systems run near-continuously July through September and condensate and coil issues dominate. The flip side is the occasional hard freeze, like the 2021 Uri event, which stresses heat pumps and exposes attic pipe and emergency-heat failures.

Our Main Richardson Services
Two services bring Richardson homeowners to the phone most often: getting the AC back before the next heat wave, and replacing a system that has finally run out of road.
AC Repair in Richardson
In the older TI-era neighborhoods off Central Expressway, techs routinely find attic ductwork so degraded by decades of 140°F summer attic heat that the flexible duct has collapsed or the inner liner separated. That matters for repair because a system laboring against failing ducts works harder than it should, and we check the whole picture before recommending parts. Richardson’s mature pecan and oak canopy adds another wrinkle: condenser pads in backyards are often shaded and leaf-clogged, which causes high-head-pressure shutdowns that look like refrigerant problems. We diagnose the actual cause before touching the equipment. For AC Repair in Richardson, call (866) 970-7959.
AC Installation in Richardson
Replacement in Richardson is rarely a straight swap. Anything built before the 1980s may need duct evaluation and an electrical check before a new condenser goes in, because an undersized panel can’t carry a modern variable-speed unit without an upgrade. We size to the house, not to the old equipment’s nameplate, and we tell you plainly when the existing ducts will fail the first August after a new system is installed. A quote that ignores the ducts is a quote for a return visit. For AC Installation in Richardson, call (866) 970-7959.
Furnace Repair in Richardson
Furnace repair in Richardson means working on heating systems installed in houses that were never built for serious cold. The 1960s and 70s ranches in 75080 and 75081 often still carry their original or second-generation heating equipment, and when a hard freeze like the 2021 Uri event hits, the failures show up fast: attic pipes, emergency-heat strips, and furnaces that sat idle for nine months. We handle every part of that, and our Furnace Repair work covers gas, electric, and heat pump systems across the city. If your heat is out, call (866) 970-7959. We answer 24/7. Fast dispatch from 7am to 7pm.
Gas Furnace Repair
Signs you need it
You smell gas near the unit, the burner flame is yellow rather than blue, the blower runs but never heats, or the furnace shuts down before reaching temperature.
What it costs in Richardson
Gas furnace repair typically runs $150 – $700, with the exact figure set by the written estimate once we’ve traced the fault.
How we do it
We shut down the gas supply, inspect the heat exchanger and burner assembly for cracks or soot, test the igniter and flame sensor, verify venting, and confirm the unit cycles safely before we leave. Gas and combustion work carries real risk, so this is not a job to attempt yourself.
Heat Pump Repair
Signs you need it
The system heats poorly when temperatures drop below freezing, the outdoor unit ices over and stays frozen, or the backup heat never kicks in during a cold snap.
What it costs in Richardson
Heat pump repair typically runs $150 – $700 depending on whether the issue is a reversing valve, defrost board, or auxiliary heat element.
How we do it
We check refrigerant charge, test the reversing valve and defrost controls, verify the emergency heat strips and sequencer, and confirm the system switches cleanly between modes.

Can you repair a furnace the same day in Richardson?
Often, yes. Most furnace failures are igniters, flame sensors, control boards, or blower motors, and we carry common parts for Goodman, Rheem, and York equipment. Call (866) 970-7959 for an exact quote. Estimates are free.
Is it worth repairing an older furnace in Richardson?
It depends on age and what failed. A heat exchanger crack usually means replacement, while a failed igniter or blower motor is a straightforward repair. We tell you which side of that line your system is on before you decide. Call (866) 970-7959 for advice.

What Richardson 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."
- Nia Robinson
