Now serving Dallas
Dallas is 15 minutes from our Farmers Branch shop on the Tollway or I-35E, so same-day calls are routine across 75201, 75204, 75206, 75214, 75218, 75225, and 75229. We stock R-22 reclaimed refrigerant for older Preston Hollow / Lakewood / Oak Cliff equipment, condensate lift pumps for Uptown and Deep Ellum high-rises, and ECM blower modules for the variable-speed equipment in newer luxury builds.
Dallas heating load context
Dallas is the urban heat-island core — peak attic temps in 1930s-50s Tudor and craftsman homes in Preston Hollow and Lakewood routinely exceed 160°F because the original ductwork is undersized and runs through unconditioned spaces never designed for central air. Uptown and Deep Ellum loft conversions add a different problem: high-rise condensate lifts that fight gravity to drain, and ECM blower boards working hard against long static-pressure runs through concrete ceilings.

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 Dallas?
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 Dallasheating 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 Dallas Homeowners Choose Frosty's for Heating Repair?
Dallas is the widest housing-age spread I work anywhere in DFW, and that one fact shapes every heating-repair call I take inside the loop. A 1920s Lakewood or M Streets bungalow with a retrofitted 80% AFUE gas furnace stuffed into an original gravity-vent flue fails for different reasons than a 1970s Preston Hollow Tudor with a second-generation replacement furnace in a tight mechanical closet, which fails for different reasons than a 2020s Far North Dallas master-plan home with a 96% AFUE condensing furnace venting through PVC sidewall pipes. Same city, three completely different service books. The prewar housing stock especially gets me — original chimneys oversized for a modern induced-draft furnace cause flue gases to condense on the way up, corrode the liner, and backfeed into the home as pressure switch faults or, worse, CO in the supply air.
February 2021 is still the single most important event shaping Dallas heating work. That 8-day hard freeze with sustained sub-20°F temperatures and multi-day power outages either killed furnaces outright (inducer motors seized from repeated cold starts, gas valves froze in position, pressure switches ice-plugged on condensing units) or exposed latent failures that have been limping along ever since. I still find February 2021 damage on Dallas diagnostics in 2026 — hairline heat exchanger cracks from the thermal shock, burner assemblies pitted from running dirty for days, board capacitors that never came back to full spec. Typical Dallas winter repair pricing: hot-surface ignitor $400 flat ($340 for Frosty Club members), flame sensor $400, gas valve $400-$1,200, inducer motor $500-$1,300, pressure switch $250-$550. Every diagnostic includes a CO test at the supply register and visual heat exchanger inspection — crack a heat exchanger, it's condemn-and-replace, never a repair.
Uptown high-rises, Deep Ellum lofts, and newer Lake Highlands and Far North Dallas builds run heat pumps rather than gas furnaces, especially in buildings where gas service is limited or in electric-only master-plan communities. Heat pump winter failures: defrost board ($650-$900), stuck reversing valve ($1,200-$1,800), outdoor TXV ($650-$950), electric heat strip elements ($400-$800 each). Steam off the outdoor unit on a 30°F Dallas morning is the defrost cycle — normal, not a problem. Refrigerant rule: systems are hermetic, so low refrigerant means a leak we locate and fix before recharging. New installs are R-454B or R-32 only; existing R-22 and R-410A systems get serviced as they are. Dallas is 20-25 minutes from our Farmers Branch shop depending on neighborhood. Call (469) 254-0548 — flat-rate, human answer, no commission-driven upsells.

What Do Dallas Homeowners Ask About Heating Repair?
How much does furnace repair cost in Dallas, TX?
Diagnostic $85 flat (waived with any repair). Common Dallas furnace repairs: hot-surface ignitor $400 ($340 for Frosty Club members), flame sensor $400 ($340), gas valve $400-$1,200 ($340-$1,020), inducer motor $500-$1,300 ($425-$1,105), pressure switch $250-$550. Flat-rate — the number I quote before I start is the number you pay.
Could February 2021 still be causing my Dallas furnace problems?
Yes, more often than anyone expects. That 8-day hard freeze damaged Dallas furnaces in ways that didn't fully surface that winter — hairline heat exchanger cracks from thermal shock, burner assemblies pitted from running dirty during outages, inducer motors with bearings stressed by repeated cold starts, and capacitors that degraded without fully failing. I still find February 2021 damage on Dallas heating diagnostics today. Fall tune-ups catch these issues in October before a December freeze exposes them at 11 PM.
Is my Dallas furnace safe to run if the heat exchanger is cracked?
No. A cracked heat exchanger leaks carbon monoxide into supply air — and in prewar Lakewood, M Streets, and Preston Hollow homes with retrofitted modern furnaces fitted into original gravity-vent flues, the risk is elevated because the flue geometry was never designed for induced-draft venting. We condemn cracked-heat-exchanger furnaces and quote full replacement. Every Dallas heating diagnostic includes a CO test at the supply register.
Why does my 1920s Lakewood bungalow furnace keep short-cycling?
Short cycling on a retrofitted prewar Dallas furnace is usually one of three things: an oversized original chimney causing flue gas condensation and pressure switch trips, undersized return ducts built around an old octopus gravity system, or flame sensor fouling from burner residue. $85 diagnostic identifies which. Flame sensor cleaning ($400 flat, $340 for members) solves about 60% of short-cycle calls; the flue issues require a deeper fix and sometimes a B-vent liner retrofit.
Do you repair heat pumps in Dallas?
Yes. Uptown high-rises, Deep Ellum lofts, newer Lake Highlands builds, and most Far North Dallas master-plan communities run heat pumps rather than gas furnaces. Common Dallas heat pump winter failures: defrost board ($650-$900), reversing valve ($1,200-$1,800), outdoor TXV ($650-$950), electric heat strip elements ($400-$800 each). We service Carrier, Trane, Goodman, Lennox, Rheem, and all major residential brands including communicating variable-speed systems.
Can You Still Service Older R-22 Heat Pumps in Dallas?
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 Lake Highlands and Preston Hollow 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 Lake Highlands and Preston Hollow?
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 Lake Highlands and Preston Hollow 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.
