Furnace repair in Plano means something different in a 1978 brick ranch off Legacy Drive than it does in a two-story in 75093 built in 2005. The first house still runs original equipment and aging refrigerant and gas lines; the second has two systems and an upstairs unit that shoulders most of the load. Sunstone AC Repair works on the brands you actually own – Goodman, Rheem, York, Daikin – and one call covers your whole system, heating and cooling, so you’re not chasing a second contractor mid-freeze. Call (866) 970-7959 for a free estimate.
Why Plano Homes Are Different
Plano isn’t one HVAC market. It’s two, split roughly by home age along the east-west corridor. Eastern and central neighborhoods around 75023 and 75075 are full of 1970s-80s brick ranch and tract homes now reaching 40 to 50 years old, with original galvanized or early-copper refrigerant lines and undersized attic duct systems. Contractors over here spend their days on full system replacements and retrofits, not new-construction work.
The northern ZIPs – 75024, 75093 and neighbors – are newer, larger two-story homes with zoned multi-system setups and two condensers per house. The failure patterns differ there: upstairs units and oversized second-floor systems that run hard and fail early. Then there’s the heat. North Texas summers push past 100°F with real humidity, and attics over the older east-side homes regularly climb to 140-150°F in August, cooking flex duct and condensate lines. Winter flips the script with ice storms and hard freezes, as in 2021. A Plano heating call in January doesn’t look much like a Plano cooling call in July, and a company that knows both is worth keeping.

Our Main Plano Services
Two calls come in more than any other from Plano homeowners: a system that won’t cool in the summer and a system that won’t heat in the winter.
AC Repair in Plano
Most of the cooling calls we take in Plano trace back to heat, not bad luck. A 1980s ranch home with an attic running near 150°F in August punishes flex duct insulation, condensate lines and refrigerant charge all at once, and that’s why these systems tend to fail in July rather than spring. On the north side of the city, a two-story with dual-zone equipment often has one upstairs unit doing most of the work. We diagnose the actual fault before recommending anything. For a closer look at how we handle it, see AC Repair in Plano.
AC Installation in Plano
Replacing a system in an older east Plano home usually involves more than swapping a condenser. Original refrigerant lines and undersized attic duct often need attention at the same time, and that changes the scope of the job. In the northern two-story neighborhoods, the conversation is usually about zoning and sizing a second-story system correctly instead of repeating an oversized install. We work through load sizing, equipment choice across your brand, and a set install date. Details on that process live on our AC Installation in Plano page.
Furnace Repair in Plano
Plano’s heating season is short but brutal when it hits. The hard freezes and ice storms that come through North Texas, like 2021, put real stress on furnaces and heat pumps that spent nine months idle, and older east-side homes with original builder-grade equipment tend to fail first. We handle furnace repair on Goodman, Rheem, York and Daikin equipment, and we diagnose the problem rather than the upsell.
Gas Furnace Repair
Gas furnaces in Plano’s older ranch homes are frequently original or one replacement old, and the heat exchanger, igniter and gas valve work in those units is where most failures land. North Texas cold snaps make a failed furnace urgent in a way a summer AC problem rarely is.
Signs you need it
You smell gas, hear a clicking igniter that never lights, or the blower runs while the air stays cool.
What it costs in Plano
Typical furnace repair in Plano runs $150 to $700 depending on the failed part, and the written estimate sets the final price.
How we do it
We shut the gas down, test the igniter and flame sensor, inspect the heat exchanger for cracks, verify gas pressure and confirm the blower and limit switch cycle correctly before restarting.
Heat Pump Repair
Heat pumps are common in Plano’s newer northern subdivisions, where dual-zone two-story homes often pair one with a conventional furnace. A hard freeze can leave a heat pump stuck in defrost or icing over, and the fix isn’t always obvious from the thermostat.
Signs you need it
The outdoor unit ices over and stays that way, the system blows cool air in heating mode, or defrost cycles run constantly.
What it costs in Plano
Heat pump repair in Plano typically falls between $150 and $700, with the written estimate setting the final figure.
How we do it
We check the reversing valve, defrost board, outdoor sensor and refrigerant charge, then verify the aux heat strips engage as designed.
What Furnace Repair Costs in Plano
| Item | Typical range in Plano |
|---|---|
| Furnace repair, minor (igniter, sensor, thermostat) | $150 – $350 |
| Furnace repair, mid-level (blower, inducer, control board) | $350 – $550 |
| Furnace repair, major (heat exchanger, gas valve) | $550 – $700 |
Can you repair my furnace the same day in Plano?
In most cases, yes. Standard failures like igniters, flame sensors and blower motors are commonly handled same day, and furnace parts for the major brands are widely available locally. Call (866) 970-7959 for an exact quote – estimates are free.
Do older Plano homes need furnace replacement instead of repair?
Sometimes. A 40-50 year old furnace with a cracked heat exchanger usually isn’t worth repairing, while a newer unit with a failed igniter almost always is. We diagnose first, then tell you honestly which side of the line you’re on. Call (866) 970-7959 for a free estimate.
Brands We Service in Plano
We’re trained and certified on nine of the most-installed residential brands, including Goodman, Rheem, York and Daikin. Knowing the specific failure points on your equipment shortens diagnosis and reduces return visits, and we keep common parts on hand for faster turnaround.

What pushes a Plano job toward the top of these ranges is usually the house, not the equipment: an older ranch home with original refrigerant lines can need line work alongside the repair, and a northern two-story with zoned systems can double the scope. Every job here gets a written upfront price before work starts, and the written estimate is what sets the final bill.

What Plano Customers Say
"AC died in August, which in this city is an emergency. He found a blown capacitor, replaced it out of the truck, and had cold air blowing in under 40 minutes. Charged me about what I'd expect to pay for the part plus a service call."
- Beatriz Garcia"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
