Now serving Plano
Plano is a 20-minute run from our Farmers Branch shop up US-75. Same-day calls are routine, and Frosty Club priority routing matters during 105°F heat-wave weeks when entire blocks need help simultaneously. We stock R-22 reclaimed for the older 75074/75075 Kings Ridge and Parker Road housing, plus ECM blower modules and zoning damper actuators for the variable-speed equipment in Willow Bend, Deerfield, and Legacy West.
Plano heating load context
Plano has more tech workers working from home than almost anywhere in DFW — Toyota North American HQ at Legacy, JPMorgan Chase in Legacy West, Capital One, Liberty Mutual, FedEx Office, Ericsson. Compressors here log 14-16 hours a day instead of the 6-8 a typical 9-to-5 household puts on them, and I've pulled dead compressors out of Deerfield and Prestonwood homes at year 8 simply because the duty cycle is roughly double the manufacturer nameplate design.

Cracked Heat Exchanger: Safety First
A cracked heat exchanger means combustion gases — including carbon monoxide — can leak into your home's air supply. We NEVER repair a cracked heat exchanger. The only safe fix is a full furnace replacement. If I find a crack during diagnostic, I red-tag the unit on the spot and show you our three replacement tiers. Learn more about CO safety at the EPA.

Join Frosty ClubWhat Are the Most Common Heating Problems in Plano?
Texas winters are mild, but furnaces still need regular service — and when they fail on a 28°F January morning, they tend to fail all at once. Here's what I see most often on Planoheating calls, and what each one typically costs to fix.
Furnace won't ignite
Failed hot-surface ignitor ($400) or coated flame sensor ($400). Both are same-day fixes. The $85 diagnostic identifies the exact cause.
Blowing cold air instead of hot
Usually a failed ignitor, bad flame sensor, or a stuck gas valve. We run a combustion analysis to confirm the exact cause before quoting.
Loud buzzing or grinding
Dying inducer motor ($500-$1,300) — the draft fan pulling combustion gases through the heat exchanger. Replace before it takes out the control board.
Short cycling (on/off/on/off)
Dirty flame sensor, failing limit switch, or restricted airflow. Can be an early warning of a heat exchanger issue — we diagnose carefully.
Gas smell or CO alarm
EMERGENCY — leave the house, call Atmos Energy at 866-322-8667, then call us. We locate the leak source and repair or red-tag as required.
Cracked heat exchanger
Carbon monoxide risk — NEVER repaired. Full furnace replacement required for safety. We confirm with combustion analyzer and bore-scope inspection.
Why Do Plano Homeowners Choose Frosty's for Heating Repair?
Plano furnaces get it easier than Chicago equipment, but 20-30 hard-freeze nights a year are more than enough to expose every weak point that hid dormant since April. The no-heat calls we get from Kings Ridge and Prestonwood in December and January cluster around three failures: cracked hot-surface ignitors ($400 flat), sooted-up flame sensors ($400), and sticking gas valves ($400-$1,200). All three present the same way — three ignition attempts, lockout, no flame. On 1980s East Plano furnaces I also pull tired inducer motors ($500-$1,300) whose bearings finally seize after 25 winter starts.
The failure I lose sleep over is the cracked heat exchanger. A crack lets combustion byproducts — including carbon monoxide — bleed into the supply air your family breathes. I don't repair cracked heat exchangers because a weld doesn't restore the OEM thickness or flame pattern; we condemn the furnace and quote a replacement. Every Plano diagnostic includes a supply-register CO reading with a calibrated combustion analyzer plus a visual on the exchanger where the burner compartment access allows. I'd rather lose the repair than let a family breathe CO — that's not negotiable.
A lot of Willow Bend, Deerfield, and Legacy West homes run heat pumps rather than gas. Winter failures look different there: defrost control boards ($450-$650), reversing valves that won't actuate ($900-$1,500), and outdoor TXV starvation. If you see steam coming off your outdoor unit on a 28°F morning, that's a normal defrost cycle, not a problem — the system briefly runs in cooling mode to melt the frost off the coil. Call (469) 254-0548 and we'll sort actual failures from normal operation for $85 flat, waived with the repair.

What Do Plano Homeowners Ask About Heating Repair?
How much does furnace repair cost in Plano, TX?
Diagnostic $85 flat, waived with any repair. Common Plano furnace repairs: hot-surface ignitor $400 ($340 Frosty Club members), flame sensor clean/replace $400 ($340), gas valve $400-$1,200 ($340-$1,020), inducer motor $500-$1,300 ($425-$1,105), pressure switch $250-$550, limit switch $300-$450. Flat-rate means you see the total before any wrench turns — no hourly billing, no parts mark-up guessing.
Is my furnace safe to run with a cracked heat exchanger?
No. Shut it off at the thermostat. A crack leaks CO into the air your family breathes — per EPA guidance on carbon monoxide exposure, even low-level chronic CO causes headaches, nausea, and heart strain. We don't weld exchangers because a field weld doesn't restore OEM specs or flame pattern. We quote a full furnace replacement and get heat restored fast. Every Plano diagnostic includes a supply-register CO measurement with a calibrated analyzer.
Do you repair heat pumps in newer Legacy West homes?
Yes. Heat pumps dominate newer Plano builds — Legacy West, the Shops at Legacy backfill, Deerfield's 2000s-era homes. Typical winter failures we see: defrost board faults, stuck reversing valves, outdoor TXV issues, and low-voltage control wire damage where the outdoor unit sat in weed-whacker range. We service Trane, Carrier, Goodman, Lennox, Rheem, Bryant, and Amana — if it's residential and on the slab, we work on it.
Why does my Plano furnace short-cycle — on two minutes, off two?
Three most common causes in Plano, in order: dirty flame sensor (the #1 fall callback — solves about 60% of short-cycle diagnoses with a $400 cleaning), restricted airflow hitting the high-limit switch (usually a choked filter or caked blower wheel), or a failing pressure switch reading a marginal inducer draft. The $85 diagnostic isolates which; I'll show you the reading on the meter so you're not trusting me blind.
My Plano furnace smells burnt the first time I ran it this fall — dangerous?
First cold-morning run of the season almost always has a brief burnt-dust smell — that's the summer's attic dust burning off the hot-surface ignitor and exchanger. It clears in 10-15 minutes, harmless. Different story if the smell is electrical (ozone, burning plastic), acrid, or smells like sulfur/rotten eggs (natural gas). Electrical: shut off at the breaker, call us. Gas: leave the house, call the gas utility first, then us.
Can You Still Service Older R-22 Heat Pumps in Plano?
Yes — EPA 608 Universal cert #2396328 lets me legally recover, recycle, and recharge R-22 under federal regulations. R-22 production ended in 2020 under the Clean Air Act phase-out (EPA.gov), so it now runs $200 per pound installed. A typical Willow Bend and Deerfield R-22 leak repair totals $650-$1,000: electronic leak detection ($250) or nitrogen leak test ($500) plus recharge at $200/lb. Optional leak seal $350 — but it can void manufacturer warranties, so I only recommend it in specific cases. For systems past 12 years with major leaks, planning the transition to R-454B or R-32 is usually the better economics. Read our R-410A phase-out explainer for DFW homeowners.
Can You Repair My R-410A Heat Pump in Willow Bend and Deerfield?
Yes — heat pumps and ACs use the same refrigerant rules. EPA 608 Universal cert #2396328 covers R-410A heat pump service. AIM Act 2025 phase-out (Energy.gov) only stops new equipment manufacture — existing Willow Bend and Deerfield heat pumps stay serviceable. Repair cost runs the same as AC: $250-$500 for leak detection plus $100/lb recharge. Repair is usually right unless the system is past 12 years old. Read our R-410A phase-out explainer for DFW homeowners.
