Fast, Reliable Furnace Repair Across Haslet
Furnace repair in Haslet, TX typically costs between $150 and $700, and most calls are completed same day when you reach us before early afternoon. Our technicians are already working the Keller, Justin, and Roanoke corridors, so a Haslet dispatch rarely waits more than an hour or two for arrival.
We’re Coldharbour Heating & Air, and we’ve been handling Furnace Repair across north Tarrant County since 2003. Our Dallas-Fort Worth office coordinates scheduling, but our crews live and work in these neighborhoods. We know the difference between a 1990s ranch on the original Haslet crossroads and a 2022 D.R. Horton build off the Alliance corridor, and we know why that matters for your heating system. If your furnace is blowing cold air, short-cycling, or not firing at all, call us at (817) 402-2972. A live person answers that line 24 hours a day, every day of the year.
Why Coldharbour Heating & Air Is Haslet’s Preferred Furnace Repair Company
Haslet homeowners have a specific problem that most HVAC companies don’t address honestly: your furnace or heat pump is probably 5 to 15 years old, built with builder-grade parts, and failing because of how it was installed, not because it’s worn out. We’re upfront about that because we’ve documented it on paper after paper across this city.
Our 365-Day Done Right Promise means every repair comes with a written guarantee before the technician leaves. If that repair fails inside a full year, we come back and fix it at no charge. No argument, no additional invoice. We also hand you a written price before any tool comes out of the bag, and that number does not change at the door. That’s The Kingswell Way, and it’s how we operate on every single call in Haslet.
Our technicians are background-checked, uniformed, and trained on nine major residential brands including Trane, Lennox, Goodman, and Rheem. The technician who shows up can work on whatever system is already in your home. No sending a rookie to stare at a part number he doesn’t recognize.
Phones are answered by a live person around the clock. Not a voicemail tree. Not a callback promise. A real human who can get a technician moving toward your home.
Heat Pump Repair in Haslet
Heat Pump Repair in Haslet covers systems that both heat and cool your home by moving refrigerant between an outdoor condenser and an indoor air handler. Because Haslet’s newer subdivisions were built with heat pumps sized primarily for summer cooling loads, we see a lot of units that can’t keep up during January cold snaps or that fail at the reversing valve when the defrost cycle can’t clear ice from exposed outdoor coils on wind-blasted rural lots.
Most heat pump repairs in Haslet fall in the same $150-$700 range as furnace work. The fix might be a failed defrost board, a stuck reversing valve, or a refrigerant leak at the indoor coil. We diagnose first, show you the written price, then repair.
Defrost Board and Reversing Valve Failures
Heat pumps in Haslet’s exposed prairie lots take a beating. No tree canopy means ice builds fast on the outdoor coil, and if the defrost board wasn’t programmed correctly at installation, the unit either never defrosts or defrosts constantly. We test the full sequence and replace the board with one matched to your exact model.
Supplemental Heat That Won’t Kick On
When outdoor temperatures drop below about 35°F, your heat pump calls on electric strip heat or a gas furnace backup. If that handoff fails, you’re left with lukewarm air and a rising electric bill. We trace the control signal and fix the relay or sequencer problem.
Heating Repair in Haslet
Heating Repair in Haslet includes furnaces, heat pumps, and any hybrid system keeping your home warm through North Texas winter. Because so many Haslet homes were built during the 2010s-2020s growth surge, most service calls involve builder-grade equipment still inside or just past the 5-year parts warranty, which means failed heat exchangers, igniters, and blower motors are usually installation defects, not age-related wear.
Repair costs run $150-$700 depending on the component. An igniter replacement might land at the lower end. A heat exchanger replacement on a mid-efficiency furnace pushes toward the higher end. We give you the exact number before we start.
Propane Furnaces on Rural Properties
Natural gas doesn’t reach every lot in Haslet, especially properties off Avondale-Haslet Road and the western rural fringe. Propane furnaces burn hotter and work harder in exposed yards with no wind shelter. We service propane conversions and stock the specialized gas valves and orifices these systems need.
Attic Air Handler Problems
Haslet’s volume builders love attic-mounted air handlers in unconditioned spaces. Those attics hit 140°F+ in summer, cooking capacitors and cracking drain pans. By January, the same equipment is asked to move 120°F air through ductwork that was barely adequate to begin with. We check static pressure, refrigerant charge, and the full electrical sequence every time.
Trusted Brands We Service in Haslet
Our technicians carry diagnostic tools and common parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Haslet specifically, we see a lot of Carrier and Goodman equipment from the 2015-2020 building boom, plus Lennox units in certain subdivisions. We stock igniters, blower motors, heat exchanger gaskets, and control boards for these brands locally, which means most Haslet repairs don’t wait on a parts run to Dallas. If your furnace is a Trane or Rheem, we’ve got you covered there too. The goal is one visit, one fix, one written guarantee.
Common Furnace Repair Problems We See in Haslet Homes
- Cracked heat exchangers from undersized returns. That single 20×20 return duct for your 3,500 square foot home creates static pressure the heat exchanger was never designed to handle. We see this block after block in Haslet’s volume-built subdivisions, and it’s why a furnace fails at year seven instead of year twenty.
- Igniter failures on propane conversions. Rural Haslet properties without natural gas rely on propane, and the higher BTU content plus harder cycling in exposed yards kills hot surface igniters faster than in sheltered urban lots.
- Flame sensor corrosion from short cycling. When a furnace can’t move enough air because of return restriction, it overheats and cycles on and off rapidly. The flame sensor gets coated with oxidation and eventually can’t detect flame at all.
- Blower motor burnout from high static pressure. The motor works overtime pulling against a restricted return. In Haslet’s 2,200-4,000 square foot tract homes with single returns, this is predictable and preventable with proper duct modification.
Pricing for Furnace Repair in Haslet, TX
Most furnace repairs in Haslet run $150-$700, with the majority falling between $250 and $450 for standard component replacements. Here’s how typical line items break down:
| Service | Price Range |
|---|---|
| Furnace Repair | $150-$700 |
| Heat Pump Repair | $150-$700 |
| Heating Repair | $150-$700 |
What moves the number? The component being replaced, whether the system is still under parts warranty, and whether we find installation defects that need documenting for a builder or warranty claim. A failed igniter on a 6-year-old Goodman might be a $180 repair with the part under warranty. A cracked heat exchanger on the same unit might require full documentation for the builder and a more involved replacement.
We give you a written, fixed price before any work begins. That price does not change. Estimates are free, and there’s no charge for us to come look. Call (817) 402-2972 to schedule.

FAQs About Furnace Repair in Haslet
Your furnace is failing because of how it was installed, not because of its age. Haslet’s post-2010 building boom means most homes here have builder-grade equipment with undersized return ducts and load calculations that prioritized speed over accuracy. High static pressure cracks heat exchangers and burns out blower motors years before they should fail. We document these installation defects so you can pursue warranty or builder claims when applicable. Call (817) 402-2972 for a free diagnostic.
Yes, we service propane furnaces throughout rural Haslet and the western fringe where natural gas lines don’t reach. These systems require specialized gas valves, orifices, and combustion analysis because propane burns hotter than natural gas. Our technicians carry the conversion parts and test equipment for these setups. Call (817) 402-2972 to schedule.
Drive time is the honest answer. Our technicians are already in the Keller and Roanoke corridors most days, so a Haslet call is rarely more than 20-30 minutes out. But properties west of Avondale-Haslet Road or on unimproved rural lots take longer to reach than a downtown Fort Worth address. We quote arrival windows we can keep, not optimistic guesses. Call (817) 402-2972 and we’ll give you a firm time.
Yes, we repair heating equipment in workshops, barns, and outbuildings across Haslet’s rural properties. These installations often use propane or electric heat and may not meet residential code for combustion air or clearances. We evaluate the setup for safe operation and give you a written price for any modifications needed. Call (817) 402-2972 to discuss your building.
A cracked heat exchanger requires replacement or full furnace replacement; it cannot be patched. Warning signs include soot around the furnace cabinet, a strong formaldehyde or “chemical” smell, water pooling beneath the unit, or the carbon monoxide detector alarming. We test with combustion analyzers and visual borescope inspection. If the heat exchanger is cracked, we show you the image and explain your options. This is not a DIY diagnosis; cracked heat exchangers can leak carbon monoxide into your home. Call (817) 402-2972 for immediate inspection.
