Flower Mound heating load context
Flower Mound runs slightly cooler overnight than the DFW core thanks to the Lewisville Lake breeze, but peak summer attic temps still hit 145-155°F. The 2,500-4,500 sqft two-story homes in Wellington and Bridlewood typically run dual systems — when the upstairs unit fails in July the primary suite hits 90°F in under an hour.

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 Flower Mound?
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 Flower Moundheating 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 Flower Mound Homeowners Choose Frosty's for Heating Repair?
Heating repair in Flower Mound centers on dual-furnace homes and aging gas equipment. Wellington's 2,350+ homes have 25-30 year old furnaces that are well past their expected service life — heat exchangers on these 1995-era 80% AFUE units are the primary safety concern. Bridlewood's golf-course community (1996-2004) runs the same generation of equipment. These homes typically have two separate gas furnaces (one per floor), fed by Atmos Energy natural gas, and when one side goes cold the homeowner often doesn't notice for days because the other furnace masks the failure. I always check both systems during a Flower Mound heating diagnostic.
The heat exchanger conversation on 25-30 year old Wellington and Bridlewood furnaces is a safety conversation, not a repair conversation. A cracked heat exchanger leaks combustion gases — including carbon monoxide — into the supply air that circulates through every bedroom. On dual-furnace homes, a cracked exchanger on the upstairs unit pushes CO directly into sleeping areas. We inspect per NFPA 54 standards and use a combustion analyzer at every supply register. When we condemn an exchanger, we shut the unit down immediately and quote replacement — we don't repair cracked exchangers because they can't be safely restored to factory spec.
Canyon Falls homes (2015+) run newer 96% AFUE two-stage furnaces that are still well within service life, but builder-grade ignitors and pressure switches fail at 7-10 years regardless of brand. Ignitor $400 ($340 for Frosty Club members), flame sensor $400 ($340), pressure switch $250-$550. On modulating furnaces common in premium Flower Mound builds, inducer motor failures ($500-$1,300) and gas valve issues ($400-$1,200) show up more because modulating components cycle more frequently. EPA 608 Universal #2396328, TACLA126718E. Call (469) 254-0548 for $85 diagnostic (waived with repair).

What Do Flower Mound Homeowners Ask About Heating Repair?
How much does furnace repair cost in Flower Mound, TX?
Diagnostic $85 flat (waived with repair). Common Flower Mound furnace repairs: hot-surface ignitor $400 ($340 for Frosty Club members), flame sensor $400 ($340), gas valve $400-$1,200, inducer motor $500-$1,300, pressure switch $250-$550. On dual-furnace homes in Wellington and Bridlewood, we check both units during every diagnostic — no extra charge for the second inspection.
My Flower Mound furnace is 25+ years old — is it safe to keep running?
Possibly not. Wellington homes built in 1995 and Bridlewood homes from 1996-2004 have furnaces well past the 15-20 year expected service life. The primary concern is heat exchanger cracks that leak carbon monoxide into your living space. Every diagnostic on a 20+ year old Flower Mound system includes a combustion analysis and CO check at supply registers per NFPA 54 standards. If we find cracks, we condemn the unit on the spot.
Only one floor of my Flower Mound home is heating — what's wrong?
On dual-furnace Wellington, Bridlewood, and Tour 18 homes, a single cold floor means one of your two furnaces has failed while the other keeps running. Common causes: failed ignitor ($400), tripped pressure switch ($250-$550), or a locked-out control board. The working furnace masks the problem — some homeowners don't notice for days. We diagnose both systems during the $85 visit.
Do you repair heat pumps in Flower Mound?
Yes. Newer all-electric Canyon Falls builds (2015+) and some recent Wellington additions run heat pumps with electric heat strip backup instead of gas furnaces. Common failures include defrost board faults, reversing valve issues, outdoor TXV problems, and electric strip element burnout. Heat pumps briefly run in cooling mode during defrost cycles — steam on a cold morning is normal, not a malfunction.
My Flower Mound furnace smells like rotten eggs — is that a gas leak?
The mercaptan smell (rotten eggs) added to natural gas by Atmos Energy means you have a gas leak. Turn off the furnace at the thermostat, do not flip any light switches, leave the house immediately, and call 911 then Atmos Energy. Do not call us first — gas leaks are a fire department situation. Once Atmos clears the leak source, call (469) 254-0548 and we'll diagnose and repair the furnace side.
Can You Still Service Older R-22 Heat Pumps in Flower Mound?
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 Wellington and Bridlewood 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 Wellington and Bridlewood?
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 Wellington and Bridlewood 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.
