We’re Coldharbour Heating & Air, and we’ve been dispatching crews to Cibolo from our San Antonio office since 2003. We know the subdivisions off FM 1103 and FM 78, the sealed attics that bake to 130°F in August, and the builder-grade heat pumps that quit when a Hill Country cold snap drops below 20°F. When your furnace fails, you need someone who recognizes your home’s equipment before they walk through the door. Call us at (817) 402-2972. A live person answers the phone, 24 hours a day.
Why Coldharbour Heating & Air Is Cibolo’s Preferred Furnace Repair Company
Our reputation in Cibolo was built one repair at a time, mostly in the same dozen or so subdivisions where production builders installed nearly identical systems between 2004 and 2018. We’ve replaced ignitors in Mesa Verde, traced gas valve failures in Deer Creek, and restored heat to families in Cibolo Creek Ranch who thought they’d be sleeping in coats. Homeowners here talk to each other, and we stay busy because our customers tell their neighbors we show up when we say we will.
Response time to Cibolo is typically under two hours for emergency no-heat calls during business hours, and our 24-hour live dispatch means you’re never routed to voicemail at midnight. We understand the local housing stock: slab framing, attic access points, and equipment platforms that repeat from one street to the next. That familiarity saves time and money. Every repair comes with our 365-Day Done Right Promise in writing before the technician leaves.
Heating Repair in Cibolo
Heating Repair in Cibolo covers everything from a failed ignitor on a 2012 Goodman gas furnace to a heat pump that won’t defrost in a subdivision off FM 78. The job starts with a diagnostic, then a written price before any work begins. Most repairs fall between $150 and $700, parts and labor included. We see two distinct patterns here: homes with natural gas furnaces in the older Cibolo Creek area, and the overwhelming majority of post-2004 tract homes with builder heat pumps or straight-cool splits that rely on electric strip heat.
Because most Cibolo homes came from one compressed 2004-2018 build era and were piped with minimal supplemental heat, sub-20°F cold snaps like Winter Storm Uri turn into neighborhood-wide emergency heat calls - an event pattern driven by builder heat pumps and straight-cool splits rather than the mixed-vintage housing seen in San Antonio. When your auxiliary heat is a 5kW strip barely sized for mild winters, a hard freeze exposes the gap immediately.
Heat Pump Defrost and Strip Heat Failures
Heat pumps in Cibolo switch to auxiliary strip heat when outdoor temperatures drop too low for efficient compressor operation. If the defrost board fails or refrigerant charge drifts low, the system ices over and shuts down completely. We test defrost initiation, measure refrigerant levels, and verify strip heat amperage draw before declaring a repair complete.
Gas Furnace Ignitor and Flame Sensor Replacement
Natural gas furnaces in Cibolo’s earlier developments use hot surface ignitors that crack after repeated thermal cycling, and flame sensors that accumulate oxidation from our higher humidity. Both are common same-day repairs. We stock both parts for Goodman and Rheem systems, the brands we see most often in local homes.
Boiler Repair in Cibolo
Boiler Repair in Cibolo is a smaller part of our business, but critical for the rural properties northeast of FM 78 and along the Marion corridor where propane is the only fuel option. Most Cibolo homeowners have forced-air furnaces or heat pumps, but rural properties on acreage often run propane-fired boilers for radiant floor heat or hydronic baseboard systems. These units require different diagnostics: testing aquastat operation, checking expansion tank pressure, and purging air locks from zones that haven’t heated evenly.
Propane boilers in exposed Hill Country properties work harder than their suburban counterparts. No wind shelter means faster heat loss, longer run cycles, and more wear on circulator pumps and zone valves. We carry common boiler parts and can often restore heat same-day, though some rural calls require extra drive time.
Propane Boiler Combustion and Venting
Propane burns differently than natural gas, and boilers converted or originally set up for propane need precise manifold pressure. We test with a digital manometer and inspect venting for proper draft, especially in outbuildings where installers sometimes cut corners on clearances.
Radiant Zone Balancing and Circulator Replacement
Uneven heating across zones usually means a stuck zone valve or failing circulator pump. We isolate each zone, check flow rates, and replace failed components. For older systems, we also evaluate whether the boiler itself is worth repairing or if replacement makes more sense given propane efficiency ratings.
Trusted Brands We Service in Cibolo
Our technicians are trained to service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Cibolo, we see Goodman and Rheem most frequently in the 2004-2012 builds, with more Lennox and Trane appearing in 2013-2018 construction. We stock common failure parts locally, capacitors, ignitors, flame sensors, blower motors, and gas valves, so most Cibolo repairs don’t wait on shipping. If your system is one of the builder-grade units now hitting its 10-to-17-year threshold, we can repair it today and give you an honest assessment of how much life remains.
Common Furnace Repair Problems We See in Cibolo Homes
- Builder heat pumps with undersized auxiliary heat. In the Mesa Verde subdivision off FM 1103, our tech answered a no-heat call on a 2007-built Lennox heat pump where the homeowner had relied on the builder’s tiny 5kW auxiliary strip and the condensing unit froze overnight. We found a failed capacitor and a refrigerant charge that had drifted low, restored defrost, and re-checked the heat exchanger and static pressure before recommending an upgrade sized by a proper load calculation for the home’s exposed west wall.
- Undersized tonnage running components to failure. Production builders in Cibolo’s mid-2000s subdivisions routinely installed 3-ton systems in homes that a proper Manual J load calculation would size at 3.5 or 4 tons. That cost-cutting decision causes systems to run continuously on peak days without ever reaching setpoint, accelerating compressor wear and generating repeat service calls from the same streets roughly a decade after original installation.
- Summer-baked attic components failing in winter. Sealed attics at 130-140°F degrade heat exchangers, wiring, and thermostat calibration faster than in mixed-vintage metros. Winter no-heat calls here often trace back to components that spent August cooking above their rated temperature.
- Propane and rural outbuilding heating issues. Properties outside Cibolo’s core subdivisions, especially toward Marion, rely on propane furnaces or boilers for shop and outbuilding heat. These systems face longer run times, exposure to wind, and occasional fuel delivery interruptions that suburban systems never encounter.

FAQs About Furnace Repair in Cibolo
Your heat pump loses efficiency below roughly 35°F and switches to auxiliary electric strip heat, which many Cibolo builders sized at only 5kW to cut costs. When temperatures drop into the teens, that strip can’t carry the load alone, especially if defrost isn’t working properly or refrigerant charge has drifted low. We test all three issues on every winter no-heat call. Call (817) 402-2972 for a free diagnostic - estimates are free.
If your system runs constantly without reaching setpoint, or if you’ve had repeat failures of the same component, a Manual J load calculation often reveals that your builder installed undersized equipment. We offer load calculations as a separate service, and the results help us recommend whether a repair is throwing good money at a fundamentally mismatched system. Call (817) 402-2972 to discuss whether a load calculation makes sense for your home.
We typically reach rural properties northeast of FM 78 and toward Marion within two to three hours for emergency no-heat calls during business hours, and our 24-hour live dispatch coordinates after-hours coverage the same way. We carry common propane boiler and furnace parts, though some specialty components may require next-day delivery. Call (817) 402-2972 and we’ll give you a firm arrival window.
Check your thermostat is set to “heat” and the temperature is above room reading, verify the circuit breaker hasn’t tripped, and confirm your propane tank isn’t empty if you’re on rural propane. Don’t open the furnace cabinet or attempt electrical repairs - the high voltage inside can kill you, and gas leaks require immediate evacuation. If those basic checks don’t restore heat, call (817) 402-2972. We’ll answer live, 24 hours a day.
Most outbuilding furnaces can be repaired if parts are available, but we evaluate whether the unit was properly sized for the space and whether venting meets code for detached structures. Propane units in shops often suffer from dust infiltration and short cycling. We give you a written repair price and an honest assessment of how much life remains. Call (817) 402-2972 for a free estimate.
