Styles & brands we work with






Furnace Maintenance in Leon Valley
Furnace Maintenance in Leon Valley is the single best way to avoid a no-heat call on the coldest night of the year, and it costs $80 – $200. Homes here, especially the 1970s-80s ranch stock with original galvanized ducts, run hard through hot humid summers and then sit dormant while oak pollen and cottonwood fluff pile up around the cabinet. When the first real cold snap comes, that’s when ignition problems reveal themselves. A maintenance visit catches weak capacitors, dirty flame sensors, and clogged intakes before they strand you.
Ignition and Burner Inspection
We pull the burner assembly and clean the flame sensor with the proper non-abrasive method. In Leon Valley, oak pollen finds its way into combustion intakes on tight side yards along Bandera Road, and a dirty sensor is the number one cause of a furnace that fires and then shuts off within three minutes.
Airflow and Static Pressure Check
Older ranch homes on slab foundations were built with duct runs we’d never design today. We check static pressure and temperature rise across the heat exchanger because high static pressure is what cracks them in the first place. This is maintenance that prevents $700 repairs.
Heat Pump Repair in Leon Valley
Heat Pump Repair in Leon Valley runs $150 – $650 and usually involves one of three things: a failing reversing valve, a capacitor that’s lost its juice, or a defrost control board that’s no longer handling our weird winter mornings. Because Leon Valley’s winters are mild but swing dramatically between 40°F nights and 75°F afternoons, heat pumps cycle constantly. That cycling wears out components faster than in cities with more predictable weather.
Reversing Valve and Defrost Failures
When a heat pump won’t switch between heating and cooling, you’ll get cold air blowing in heat mode, or the outdoor coil will ice up and stay iced. We diagnose it with a gauge set and a meter, and we give you the written price before we touch a wrench.
Capacitor and Control Board Issues
Summer thunderstorms in Leon Valley bring lightning strikes that fry control boards. We see it every year. The fix is straightforward, the part is common, and we keep the most frequent boards for Trane, Carrier, and Goodman units stocked in our vans so we don’t have to make you wait on a parts house run to San Antonio.
Trusted Brands We Service in Leon Valley
The furnaces and heat pumps we repair in Leon Valley are mostly Goodman, Rheem, and York units in the older homes, with Daikin popping up in newer infill construction. We’re certified to service all of them, along with Carrier, Trane, Lennox, and Bryant. For Leon Valley customers, we keep high-failure parts like ignitors, flame sensors, capacitors, and pressure switches in stock locally. That means less waiting and a faster fix when your furnace is down. If we need a specialty part, we can source it same day from our San Antonio parts network.
Common Furnace Repair Problems We See in Leon Valley Homes
- Electrode and flame sensor fouling from oak pollen and cottonwood fluff. Leon Valley’s mature tree canopy is beautiful, but it dumps debris into exterior furnace intakes every spring and fall. A fouled sensor causes short cycling and burner shutdowns.
- High static pressure in original galvanized ducts. Homes built in the 1960s-80s often have undersized returns and leaky plenums. Static pressure over 0.8 inches of water column shortens blower motor life and can overheat the heat exchanger.
- Control board failure after lightning storms. Summer and fall thunderstorms roll through Leon Valley regularly, and a nearby strike can fry the board even if nothing else in the house is damaged. The furnace simply won’t respond to the thermostat.
- Builder-grade furnaces in newer infill with load calculation mismatches. Some of the new construction tucked between older Leon Valley ranch homes has furnaces sized by rule of thumb, not a proper Manual J. The result is a heat exchanger that cycles too often and fails early.

FAQs About Furnace Repair in Leon Valley
Leon Valley’s older ranch homes often still have original galvanized ductwork that was undersized from the start, which drives up static pressure and makes the blower work harder than it should. Add oak pollen and cottonwood fluff collecting on the blower wheel and the motor runs hot and wears out early. We measure static pressure on every diagnostic call specifically for this reason. Call (903) 623-6784 if your blower is surging or noisy.
Probably not for the full term, and we see this constantly in Leon Valley’s newer infill homes. Most manufacturers require registration within 60 or 90 days of installation. If it wasn’t registered, the parts warranty drops from 10 years to a base 5-year term, and some components drop to 1 year. We can check your specific unit’s status during a diagnostic and tell you exactly what’s covered before we order parts. Call (903) 623-6784 and we’ll pull it up.
In Leon Valley, the most common culprit is a dirty or failing flame sensor, and the fouling is almost always organic debris from the area’s oak canopy. The sensor can’t hold a signal through the buildup, so the control board shuts the burner down as a safety measure. It’s the first thing we check, and the fix is often under $200. Call (903) 623-6784 if you hear the furnace cycle on and off.
Yes, and this is one of the things that makes Leon Valley different from most of the San Antonio metro. The shallow, rocky soil here makes duct rerouting a jackhammer project, so we always try to work with the existing galvanized runs first. Sealing plenum joints with mastic, adding a return-air drop, and balancing dampers resolves most airflow problems without tearing up your slab. Call (903) 623-6784 and we’ll measure before we recommend anything invasive.
Once a year, in the early fall before the first cold snap. The pollen and cottonwood season in Leon Valley leaves residue that hardens over the summer, and the first ignition of the season is when weak capacitors and dirty sensors fail. Annual maintenance runs $80 – $200 and catches these problems before they become a $600 repair. Call (903) 623-6784 to schedule, and we’ll send you a live arrival time.
