AfterFast, Reliable Furnace Repair Across Wimberley
Most furnace repairs in Wimberley run $150-$700 and are completed in a single visit, with our technicians carrying the propane-specific parts and heat-pump components that match what actually heats homes here. We’re on call around the clock, and a live person answers the phone at (817) 402-2972 every hour of every day. Our Furnace Repair team dispatches from our Dallas-Fort Worth coordination office with crews already staged in the Hill Country, so we’re not driving up from San Antonio when your heat goes out on a February night.
Wimberley’s different. Nearly every home here heats with propane or electricity, not natural gas, because there’s no gas distribution infrastructure in the Blanco River valley. That single fact changes every diagnostic conversation, every parts run, and every replacement recommendation. We’ve spent two decades learning what fails in cedar-and-limestone custom builds, in 1990s ranch houses on pier-and-beam foundations, and in vacation cabins that sit dark for three weeks then fire up hard on a holiday weekend. We know the local propane suppliers, the common igniter and gas-valve failures on the brands installed here, and how cedar pollen season turns a dormant system’s blower wheel into a choked mess by March.
Why Coldharbour Heating & Air Is Wimberley’s Preferred Furnace Repair Company
We’ve been part of the Kingswell network since 2003, operating as an independently owned company that answers to Wimberley homeowners, not a corporate office. The Kingswell Guarantee means four written promises on every job: a price before the work starts, a firm arrival window, a clean job site, and our 365-Day Done Right Promise. If a repair fails within a full year, we come back and correct it at no charge. That guarantee is written down before our technician leaves, not offered as a verbal afterthought.
Our technicians are background-checked, uniformed, and trained on nine major residential brands including Trane, Lennox, Goodman, and Rheem. They carry the propane conversion kits, gas valves, and heat-pump defrost boards that Wimberley systems actually need. When a weekend homeowner from Austin calls from a house off River Road with no heat, our tech knows to check the propane tank level first, then the regulator pressure, then the furnace sequence of operation. That local fluency saves an hour on every call.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail trees, no callback queues, no “leave a message and we’ll get back to you in the morning” when it’s 28 degrees in the valley and your heat pump is blowing cold air.
Furnace Tune Up in Wimberley
Furnace Tune Up service in Wimberley is designed around a reality most markets don’t face: a significant share of local HVAC systems sit unused for weeks, then run continuously through holiday weekends and summer escapes. That boom-bust cycle accelerates wear on every component, and deferred maintenance failures are far more common here than in full-time occupied homes. Our tune-up runs $80-$200 and includes a complete combustion analysis on propane furnaces, heat-exchanger inspection, burner orifice cleaning, capacitor testing, and a written report of what we found.
Propane System Inspection and Combustion Check
Propane burns hotter and drier than natural gas, and the orifices and burner ports in Wimberley furnaces clog faster from sediment and spider webs during long idle periods. We pull and clean every burner, check flame color and pattern, and run a combustion analysis to verify safe CO levels and proper oxygen mix. A yellow or lazy flame on a propane furnace isn’t just inefficient, it’s dangerous. We document the readings and show you the printout.
Filter and Coil Assessment for Dormant Systems
Cedar pollen from December through February produces some of the highest airborne counts in the country. In vacation homes that weren’t filter-changed all winter, we routinely find evaporator coils and blower wheels caked with fine yellow dust that chokes airflow and drives static pressure past the high-limit switch. We measure static pressure across the coil, photograph what we find, and recommend a high-MERV media cabinet upgrade if the standard 1-inch filter isn’t cutting it.
Emergency Furnace Repair in Wimberley
Emergency Furnace Repair in Wimberley means responding to no-heat calls when valley-trapped cold air has pushed temperatures below freezing and your system wasn’t sized for sustained sub-freezing operation. Winter Storm Uri proved how many Hill Country homes were fitted with bare-minimum heating capacity. Our emergency rate falls within the standard $150-$700 repair range, we do not charge overtime premiums, and a live person takes your call at (817) 402-2972 at any hour.
No-Heat Diagnostics in Propane and Heat-Pump Systems
When a Wimberley homeowner calls with no heat, our first questions are about fuel source and recent occupancy. Propane tank empty? Regulator frozen? Heat pump locked out on defrost failure with no auxiliary heat to carry the load? We sequence the diagnostic differently for propane furnaces versus heat pumps with electric strips, and we carry the igniters, gas valves, pressure switches, and defrost boards for both. Most emergency calls are resolved same visit.
Weekend and Holiday Response for Vacation Properties
We understand the panic call from an Austin or San Antonio owner who’s arrived Friday evening to a 52-degree house. Our technicians are staged for Hill Country response, not driving from distant metros, and we prioritize occupied homes with vulnerable residents. We’ll get your propane furnace firing or your heat pump staged correctly before the weekend is wasted.
Trusted Brands We Service in Wimberley
Our technicians are trained to service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, and we stock the propane conversion components, gas valves, and ignition modules most commonly needed for the Goodman and Rheem furnaces installed in Wimberley’s 1990s and 2000s building boom. For Trane and Lennox heat pumps paired with propane furnaces in newer custom builds, we carry OEM defrost boards and auxiliary heat sequencers. Local parts availability means most repairs are completed without a return trip, and our Dallas-Fort Worth coordination office can expedite same-day freight for the oddball component when needed.
Common Furnace Repair Problems We See in Wimberley Homes
- Failed hot-surface igniters in propane furnaces after long idle periods. Vacation homes sit dark for weeks, then the furnace fires up on a holiday weekend with a cracked igniter that was already near failure. The homeowner arrives to a cold house and a blinking error code. We replace the igniter, check flame rollout, and verify the gas valve opens fully on sequence.
- Cedar pollen choking blower wheels and secondary heat exchangers. Second homes that missed winter filter changes accumulate fine pollen that coats every surface. Static pressure climbs, airflow drops, and the high-limit switch trips repeatedly. We clean the blower assembly, inspect the secondary heat exchanger for blockage, and upsize filtration to a 4-inch media cabinet where the ductwork allows.
- Heat pumps without auxiliary heat failing to hold setpoint during Arctic intrusions. Many 1990s Hill Country builds were fitted with heat pumps and no electric heat strips, adequate for typical winters but not for valley-trapped cold air below 20°F. The compressor short-cycles, the house drifts cold, and the homeowner assumes the furnace is broken. We evaluate whether adding heat strips or upgrading to a properly sized propane furnace is the right path.
- Undersized propane tanks causing fuel-starved short-cycling. A 250-gallon tank serving a large custom build with a 100,000 BTU propane furnace can drop pressure below the regulator’s capacity during sustained cold, causing the burner to flutter and the pressure switch to drop out. We check tank level, regulator output pressure, and line sizing, then coordinate with the homeowner’s propane supplier if the system is underfueled for the load.

FAQs About Furnace Repair in Wimberley
That sharp, sulfurous odor is usually accumulated dust burning off the heat exchanger and burner assembly, combined with residual propane mercaptan (the odorant added for leak detection) that concentrates in a stagnant duct system. If the smell dissipates within 20 minutes and doesn’t recur, it’s typically harmless. If it persists, smells like rotten eggs, or you feel dizzy or nauseous, shut the system off immediately and call us at (817) 402-2972. We check for combustion spillage, cracked heat exchangers, and proper venting on every startup call.
Not necessarily. Many Wimberley heat pumps were installed without electric auxiliary heat strips, which means when outdoor temperature drops below the balance point (often around 35°F in older systems), the compressor alone cannot maintain setpoint. We evaluate whether adding properly sized heat strips, improving insulation and air sealing, or upgrading to a propane furnace is the most cost-effective solution for your specific home and usage pattern. Call (817) 402-2972 for a free assessment.
Every heating system decision in Wimberley starts with fuel source: propane or electricity. Propane furnaces require different gas valves, orifices, pressure settings, and venting than natural gas units, and replacement options are more limited. Heat pumps are common but must be sized for Hill Country temperature extremes, not just cooling load. Our technicians are trained on both fuel types and carry the propane-specific parts that San Marcos or Kyle techs rarely need.
Short-cycling in Wimberley vacation homes usually traces to one of three causes: a clogged filter or pollen-caked coil restricting airflow and tripping the high-limit switch; a propane pressure or regulator issue causing flame instability; or an oversized furnace heating the space too quickly then shutting off before the thermostat is satisfied. We measure static pressure, check combustion, and evaluate thermostat location and duct design to find the root cause, not just replace the part that failed.
Yes. Multi-zone homes with propane/heat-pump hybrids require commissioning verification that single-zone systems don’t. Zone dampers can stick, thermostats can lose staging logic, and a failure in one system can overload the other. We were called to a cedar-and-limestone custom build off River Road where the homeowners, Austin-based weekenders, reported the propane furnace short-cycling on holiday weekends while the house sat at 58°F. Our tech found a failed run capacitor on the induced-draft blower motor, but the real story was a 40°F return-air drop across a cedar-pollen-caked evaporator coil that was throwing static pressure way out of spec and tripping the high-limit. We cleaned the coil, upsized filtration to a high-MERV media cabinet, replaced the capacitor, and recalibrated the thermostat, then confirmed the 5-ton, two-system propane/heat-pump hybrid was actually staging correctly on the second zone. That’s the level of systems thinking a complex Wimberley home demands.
