Styles & brands we work with
Furnace Maintenance in Alamo Heights
Furnace Maintenance in Alamo Heights is not a luxury; it’s the difference between a furnace that dies on the first cold snap and one that runs quietly for another season. Routine maintenance runs $80 to $200, and it includes a full safety check of the heat exchanger, burner assembly, and gas valve, plus a blower motor inspection and filter replacement. In older Alamo Heights homes, we also check static pressure and duct integrity, because original ductwork is often the hidden cause of uneven heat.
What We Check During a Tune-Up
We inspect the heat exchanger for cracks or rust, test the ignitor and flame sensor, and measure gas pressure at the manifold. We also check the blower wheel for dust buildup that reduces airflow and forces the furnace to work harder. In homes with converted gravity furnaces, we pay special attention to return air because those systems were never designed for modern blowers.
When Alamo Heights Homeowners Should Schedule It
The best time for furnace maintenance in Alamo Heights is October or early November, before the first real cold front. We also recommend a mid-season check in January if you have an older system, especially in homes with original ductwork that tends to collect dust. A tune-up catches small problems before they become a $700 repair.
Heat Pump Repair in Alamo Heights
Heat Pump Repair in Alamo Heights has its own set of failure patterns because many of the larger, newer homes here use heat pumps for both heating and cooling. Repair costs fall within the same $150 to $700 range as furnace work, depending on the component. A bad reversing valve, a failed defrost control board, or a refrigerant leak are the most common call-outs we see in this part of town.
Why Heat Pump Problems Get Misdiagnosed
Heat pumps are often blamed for problems that actually trace back to the ductwork, especially in Alamo Heights homes where the system was added to an older structure. Leaky ducts pull cold attic air into the return, which makes the heat pump run constantly and trips the high-limit switch. We test static pressure on every heat pump diagnostic call because it’s the fastest way to separate an equipment failure from an airflow problem.
When a Heat Pump Needs Refrigerant Work
If your heat pump is blowing lukewarm air in heating mode and the outdoor unit is covered in frost, you may have a refrigerant leak. We perform a leak search, repair the source, and recharge the system to the manufacturer’s exact specifications. This is not a “top it off and hope” service; we fix the leak or we don’t do the job.
Trusted Brands We Service in Alamo Heights
Our technicians are certified to service Carrier, Trane, American Standard, Daikin, Bryant, and most other major brands found in Alamo Heights homes. We keep common replacement parts for these systems stocked on our trucks, so a blower motor or ignitor replacement often happens on the first visit. If it’s a Carrier or Bryant system, we can pull OEM parts from local suppliers the same day, which means less downtime for your home.
Common Furnace Repair Problems We See in Alamo Heights Homes
- Oversized furnaces short-cycling in mild weather. Many Alamo Heights homes have furnaces that were oversized for the original structure and never right-sized after additions or renovations. Short cycling causes condensation on the heat exchanger, which leads to rust, cracks, and premature failure. We correct this by adjusting gas pressure, blower speed, and, where needed, recommending a properly sized replacement.
- Leaky original ductwork pulling humid attic air. In older Alamo Heights homes, duct joints sealed with 1950s tape have long since failed. The result is humid attic air being pulled into the system, which corrodes the evaporator coil and creates a musty smell that gets worse when the furnace runs. We seal accessible ducts with mastic and check the return plenum for gaps.
- Outdated electrical panels with no spare breaker space. Many 1920s and 1930s Alamo Heights homes still have original electrical panels with no room for a modern high-efficiency furnace. When a new furnace needs its own dedicated circuit, we coordinate the sub-panel work so the installation passes inspection and the furnace runs on stable power.
- Failed ignitors and dirty flame sensors. The most common single part that fails on gas furnaces in Alamo Heights is the hot surface ignitor. It’s a ceramic element that glows to light the burner, and in homes with original gas lines, small debris from the lines shortens its life. We replace ignitors with OEM parts and clean the flame sensor as part of the job.

FAQs About Furnace Repair in Alamo Heights
We work around the original construction, not through it. That means we access the furnace from the mechanical room or crawl space, run new thermostat wire along existing chases, and avoid cutting into plaster walls unless there’s no other option. Most repairs in older Alamo Heights homes don’t require opening walls at all. When we do need access, we cut small, clean openings and coordinate repair with a local plaster contractor we trust.
Yes, in most cases the heat exchanger on a converted gravity furnace comes out through the front or side of the cabinet, not through the floor registers. We’ve done this on several Alamo Heights homes with original floor grates and oak floors, and the registers stay exactly where they are. We’ll confirm the access path during the diagnostic visit and show you exactly how the repair will happen before we order parts.
This is a real question in Alamo Heights, where many 1920s and 1930s homes still run on original radiant boilers. If your boiler needs a minor repair, fix it. If it needs a major repair like a cracked heat exchanger or a new circulator pump, switching to a forced-air furnace usually makes more sense, especially if you’re planning to add central air. We can do a load calculation on your home and show you the numbers for both paths, including what it costs to run new ductwork through a pier-and-beam foundation.
Yes, and we do it on almost every call to older Alamo Heights homes. Old mercury thermostats drift out of calibration, which causes the furnace to short cycle or run too long. We calibrate them when they’re worth keeping, and when they’re not, we recommend a modern thermostat that works with your existing wiring. A wall-mounted wireless thermostat with a remote sensor can fix temperature swings in homes with no thermostat wiring in the living space.
Furnace repair in Alamo Heights runs $150 to $700, which is in line with the rest of San Antonio. The difference is that Alamo Heights homes more often need additional work on original ductwork, electrical panels, or converted gravity furnaces, which can add to the total job cost. We’ll always separate the furnace repair cost from any ancillary work so you know exactly what you’re paying for. Call (903) 623-6784 and we’ll give you a written quote before anything starts.
Yes. We answer calls 24/7, and we won’t make you leave a message. If your furnace quits on a 25-degree night, call (903) 623-6784 and you’ll talk to a real person who can dispatch a technician to Alamo Heights the same day. Emergency calls don’t cost extra in overtime, and the repair still includes the written guarantee and free second visit if it fails.
The Alamo Heights Homes We Know Well
Alamo Heights is a mix of historic 1920s-1950s homes and newer custom builds, which means the furnace work here rarely looks the same twice. In the older sections off Broadway, we see original pier-and-beam foundations with gravity furnaces that were converted to central air decades ago. The ducts were undersized for modern blowers, so static pressure runs high and the furnace works harder than it should. In a 1930s cottage near Broadway, our crew traced a Carrier furnace cycling on limit to a failing blower motor and a badly rusted heat exchanger from years of high humidity. We replaced the heat exchanger and blower, sealed the return plenum, and verified static pressure dropped from 0.9″ to 0.5″. Quiet heat and no more short-cycling.
That’s the kind of repair you can’t do with a generic checklist. It takes knowing how Alamo Heights homes were built, what’s been changed since, and what failure mode comes next. That’s the information we bring to every call.
