Styles & brands we work with
Gas Furnace Repair in Boerne
Gas Furnace Repair in Boerne covers the burners, ignition system, gas valve, heat exchanger, control board, and blower on a natural gas or propane furnace. Most homes in Boerne run original or aging gas furnaces that haven’t been opened in years, and the first cold snap in November is when we get the calls: burner won’t stay lit, blower runs but no heat, weird smell on startup, or a furnace that short cycles every ten minutes.
A typical gas furnace repair in Boerne runs $150 to $700 depending on the failed part. Ignitor replacement usually lands at the low end. A blower motor or gas valve pushes toward the upper end. You’ll get the exact number in writing before any work starts, and the repair is guaranteed for 365 days.
Heat Exchanger and Gas Valve Work
A cracked heat exchanger is a carbon monoxide risk, not a “wait and see” item. When we inspect a furnace in Boerne and find a crack, we show you a photo, explain the option plainly, and shut the unit down if needed. We don’t patch heat exchangers and we don’t tell you to run it anyway. Gas valve replacement is simpler: sticky valves and failing regulators show up as weak flames or a furnace that lights and drops out within seconds.
Ignitor and Blower Motor Replacement
Ignitors burn out more often in Boerne than people expect, especially on furnaces that cycle hard during January freeze spells. If your furnace clicks but won’t light, it’s often a $150 to $300 part replacement. Blower motor failures are pricier and messier; bad bearings whine first, then seize. We stock common motors for Trane, Carrier, and Goodman units on our local trucks to cut turnaround time.
Furnace Tune Up in Boerne
Furnace Tune Up in Boerne is a full inspection and adjustment of your furnace before the heating season. Boerne sits at the edge of the Hill Country, and after a long hot summer followed by a damp fall, furnaces here collect dust, rust, and dead insects in the burner cavity. A tune-up catches small problems before the first hard freeze, when every HVAC company in Kendall County gets slammed at once.
Our tune-up runs $80 to $200 and includes a combustion check, thermostat calibration, filter replacement, blower inspection, and a written report of what we found and what it means. The technician is not paid on what they sell. You get a flat price and an honest assessment, nothing else.
Static Pressure and Duct Check
We test static pressure on every Boerne tune-up. Tightly sealed homes, especially newer builds in developments along Highway 46 and the east side, often have restrictive ductwork that drives static pressure too high. A furnace that trips its high-limit switch over and over is usually fighting a duct problem, not a bad limit switch. We find the restriction and tell you what it would cost to fix, separately from the tune-up.
Capacitor and Electrical Inspection
Capacitors fail from heat, and Boerne’s west-facing condenser units sit in brutal afternoon sun off limestone walls and driveways. Our techs test capacitors during every tune-up, not just when the system dies. A weak capacitor costs under $100 to replace before it takes out a compressor; an ignored one becomes a $2,000 problem in July. That’s the local math, and we’re blunt about it.
Trusted Brands We Service in Boerne
We repair and maintain all major residential furnace brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Our trucks carry common ignitors, flame sensors, capacitors, and blower motors for these brands so Boerne customers aren’t waiting two days for a part from San Antonio or Austin. If your system is a Bryant, Daikin, or American Standard, we know their common failure points cold and can usually diagnose a no-heat call in under an hour. We also service dual-fuel systems, which are common in Boerne’s newer custom builds where a heat pump handles shoulder season and a gas furnace takes over below 40°F.

AfterCommon Furnace Repair Problems We See in Boerne Homes
- High-limit trips from tight ductwork. Many newer Boerne homes are sealed tight for AC efficiency, but the ductwork wasn’t sized for the furnace airflow. Static pressure climbs, the limit switch trips, and the furnace shuts down mid-cycle. Fixing the duct solves the problem permanently; swapping the limit switch just resets the timer.
- Mini-split heads losing heat on freeze nights. Historic limestone rooms and additions without ductwork often run mini-split heat pumps. When temps drop into the 20s, outdoor coils ice over and heating capacity falls off a cliff. We see this in downtown Boerne’s older stone homes every winter. A proper defrost check and charge adjustment makes a real difference.
- Capacitor failures on west-facing units. Original 1990s condensers mounted on west walls absorb reflected limestone heat all afternoon. Head pressure climbs, capacitors cook, and dual-fuel systems lose heat when the compressor won’t start. We carry surge-rated capacitors and check refrigerant charge before the first heat wave each May.
- Crushed return ducts in attics. Boerne homes with attic-mounted furnaces often have return ducts that got stepped on during insulation work or roof repairs. A crushed return starves the blower, air noise rises, and the furnace overheats. We see this at least once a week during winter in every Boerne subdivision we serve.

FAQs About Furnace Repair in Boerne
Your furnace trips the high-limit switch because air isn’t moving across the heat exchanger fast enough, and in Boerne that’s usually a duct problem: crushed return ducts in the attic, closed or buried supply vents, or ductwork that was undersized from the day it was installed. Tight new construction makes it worse because the house can’t pull in outside air. We check static pressure on every call and find the restriction instead of resetting the limit switch and hoping. Call (361) 470-8872 and we’ll diagnose it properly.
Yes, a properly sized cold-climate mini-split can heat a limestone room in Boerne down to about 5°F, but many older installs here aren’t sized for freeze nights and lose capacity when the outdoor coil ices over. Historic limestone walls hold cold and radiate it inward for days after a freeze. We service these systems and can tell you whether your current unit is right for the room or whether a supplemental heat source makes more sense for deep winter. We’ll give you a straight answer and a written price for any repair.
We recommend testing capacitors once a year, ideally in spring before the heat arrives, because Boerne’s west-facing condenser units degrade capacitors faster than nearly any other part of the HVAC system. Reflected limestone heat drives head pressures up and cooks the capacitor slowly until it fails on the first hot or cold snap. Our tune-up includes a capacitor test, and replacing a weak one before it fails costs under $100. Call (361) 470-8872 to schedule a check.
Your R-22 condenser struggles in Boerne because west-facing limestone walls and driveways reflect afternoon heat directly into the unit, pushing head pressures far higher than the same equipment sees in San Antonio’s shadier, flatter terrain. Add mineral-heavy Edwards Aquifer water accelerating coil corrosion, and you get compressor failures every July in Boerne that San Antonio HVAC companies just don’t see at the same rate. When we find an R-22 system failing, we walk you through repair versus replacement costs honestly.
Most furnace replacements in Boerne require a mechanical permit through the city, and historic homes in the downtown district may need additional review. We handle the permit paperwork as part of the job and coordinate with the city so you’re not making calls. We’ve done this enough in Boerne’s historic districts to know what inspectors look for and what makes the process move. Call (361) 470-8872 and we’ll tell you what your specific property needs.
If your furnace is acting up in Boerne, don’t guess and don’t wait for the next cold front to make it worse. Call (361) 470-8872 for a free estimate. You’ll get a live person, a written price, and a technician you already know by name and face before the door opens.
