Now serving Keller
Keller is about 35 minutes from our Farmers Branch shop via TX-114 west to TX-170. We try to batch Keller routes to keep response time tight, so book early when possible. We stock ECM blower modules, zoning control boards, and TXV kits for the Carrier Infinity / Trane XV communicating dual-zone systems common in Hidden Lakes, Marshall Ridge, Estancia, and the Oaks of Fossil Ridge.
Keller heating load context
Keller homes are predominantly 3,500-5,500 sqft custom two-stories on half-acre-plus lots built 1995-2015, almost all running dual-zone HVAC with two air handlers, two condensers, and zoning dampers. The half-acre-plus lots also mean longer refrigerant line sets — leaks have more places to hide, and TXV / ECM control-board faults on the upstairs zone are the dominant Keller failure mode rather than capacitor or contactor issues.
How Much Does Heating Repair Cost in Keller?
Furnace repair in Keller starts at $85 for the diagnostic (waived with any repair). Most common heating repairs fall in the $250-$1,300 range. We're flat-rate, which means the price quoted before we start is the price you pay at the end. Frosty Club members save 10-15% on every repair.

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 Keller?
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 Kellerheating 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 Keller Homeowners Choose Frosty's for Heating Repair?
Keller heating repair comes with a dual-zone wrinkle that almost no other DFW city has at the same frequency: the 3,500-5,500 sqft two-story KISD family homes in Hidden Lakes, Marshall Ridge, The Oaks of Fossil Ridge, and Bloomfield ship with two furnaces and two air handlers — one for downstairs, one for upstairs — which means diagnosing a no-heat complaint in a Keller home is really two diagnostics in one. I've lost count of the calls where the homeowner says 'the whole heater is broken' and I find one zone running fine while the other has a dead inducer motor or a fouled flame sensor. That zone-specific failure pattern matters for pricing because on a dual-zone Keller repair I only charge one diagnostic ($85 flat, waived with repair), not two.
The 2000s-2010s Keller master-plan housing boom produced a lot of communicating variable-speed systems (Carrier Infinity, Trane ComfortLink II, Lennox iComfort) with tri-zone damper boards that coordinate across both floors. When the handshake between thermostat, zone controller, and variable-speed blower drops — often after a power surge during Tarrant County storms — the whole system can default to emergency strip heat or lock out one zone entirely. Integrated control board replacement runs $600-$1,200 ($510-$1,020 for Frosty Club members). Typical other Keller winter pricing: hot-surface ignitor $400 flat ($340 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 of the active zone and heat exchanger inspection on both furnaces — crack a heat exchanger, it's condemn-and-replace, never a repair.
Newer Keller builds in Estancia and the latest Hidden Lakes phases run heat pumps with electric strip backup for the upstairs zone and gas furnace for the downstairs. 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). Refrigerant rule: systems are hermetic; low refrigerant means a leak I find before recharging. New installs R-454B or R-32 only. Keller is 35 minutes from our Farmers Branch shop — Frosty Club priority scheduling matters on dual-zone diagnostic calls during freeze weeks. Call (469) 254-0548, flat-rate, human answer.

What Do Keller Homeowners Ask About Heating Repair?
How much does furnace repair cost in Keller, TX?
Diagnostic $85 flat (waived with any repair). On Keller's dual-zone homes that's one diagnostic fee, not two, even if I check both furnaces. Common Keller 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), integrated control board $600-$1,200 ($510-$1,020), pressure switch $250-$550. Flat-rate pricing.
My upstairs Keller zone is cold but downstairs works fine — why?
Your home has two furnaces (one per zone) and the upstairs unit has failed independently. Most common causes: dead inducer motor ($500-$1,300), fouled flame sensor ($400), failed hot-surface ignitor ($400), or pressure switch fault ($250-$550) on the upstairs air handler. Zone damper actuators stuck closed also produce this symptom. $85 diagnostic identifies which; repair is flat-rate.
Is my Keller furnace safe to run if the heat exchanger is cracked?
No. A cracked heat exchanger leaks carbon monoxide into supply air of whichever zone it serves — and in a Keller home with a kid's bedroom upstairs, a cracked upstairs furnace can fill the room with CO overnight while the downstairs reads normal. We condemn cracked-heat-exchanger furnaces and quote full replacement. Every Keller diagnostic includes a CO test on the active zone's supply register and heat exchanger inspection on both furnaces.
Why does my Keller communicating thermostat say 'comm error' after a storm?
Tarrant County thunderstorm power surges are the #1 cause of communicating-thermostat handshake failures on Carrier Infinity, Trane ComfortLink II, and Lennox iComfort systems. The proprietary data line between thermostat, zone controller, and variable-speed blower drops, and the system defaults to emergency strip heat or lockout. Most are fixed at the $85 diagnostic by re-pairing; failed control boards run $600-$1,200.
Do you repair heat pumps in Keller?
Yes — heat pumps are common in newer Estancia and latest Hidden Lakes phase builds, often paired with a gas furnace on the opposite zone. Common Keller 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.
Can You Still Service Older R-22 Heat Pumps in Keller?
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 Hidden Lakes and Marshall Ridge 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 Hidden Lakes and Marshall Ridge?
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 Hidden Lakes and Marshall Ridge 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.
