Roy Jaramillo, Owner
San Antonio local since 2008
San Antonio runs AC for 7-8 months a year. Temperatures regularly hit 100°F and humidity adds to the cooling load from May through October. The HVAC system in a San Antonio home works harder than almost anywhere else in the country, and that sustained stress separates well-maintained systems from neglected ones fast.
San Antonio winters are mild compared to the north, but when temperatures drop to the 30s, a broken furnace is still a serious problem for home comfort — especially for families with young children or elderly members at home.
Amazing Air Solutions repairs furnaces and heating systems throughout San Antonio. Roy's reliable team of HVAC professionals diagnoses heating problems correctly the first time and gives our customers the price before any work begins.
We repair gas furnaces, electric furnaces, heat pumps, and package units. Whether it's an ignitor failure, a blower motor, a heat exchanger issue, or a control board — our technicians have seen it and fixed it. Contact us for a free diagnosis.
No heat in cold weather qualifies as an emergency call. We prioritize these.
Common Furnace Repairs We Handle
Ignitor & Thermocouple Replacement
The most common reason a gas furnace won't light. Usually a same-visit fix.
Blower Motor Repair
No airflow or weak airflow with the heat running often traces back to the blower.
Heat Exchanger Inspection
Cracked heat exchangers are a carbon monoxide risk. We inspect and report before anything else.
Control Board Replacement
Modern furnaces fail at the circuit board. We test before recommending replacement.
Gas Valve & Pressure Issues
Low gas pressure or faulty valves prevent proper combustion. We test and adjust.
Limit Switch Reset & Replacement
Furnaces that short-cycle or overheat often have a failed or tripped limit switch.
Serving San Antonio, TX
We serve all San Antonio neighborhoods — Stone Oak, Alamo Heights, the Medical Center, Northside, Westside, South Side, and everywhere in between.
San Antonio's housing stock spans everything from 1940s limestone cottages in historic neighborhoods like Mahncke Park and Woodlawn to 2020s construction on the far northwest and south sides. Older homes frequently have undersized or deteriorating ductwork that limits what even a properly sized new system can deliver. Homes from the 1980s and 1990s are the most common candidates for duct inspection and sealing.
The issues we see most across San Antonio: capacitor failures from sustained summer load, refrigerant leaks in systems over 8 years old, and condensate drain clogs from high humidity. Homes near open limestone terrain accumulate more airborne dust, which accelerates coil contamination and filter clogging. Attic temperatures in San Antonio can exceed 150°F on hot days, putting extra stress on ductwork and components in unconditioned space.
All service in San Antonio is performed by Amazing Air Solutions technicians from our San Antonio home base. Same team, same standards, same upfront pricing.

Frequently Asked Questions
How quickly can you respond for furnace repair in San Antonio?
For heating emergencies in San Antonio our reliable team prioritizes same-day response, especially during cold snaps. No heat means no home comfort — we take that seriously. Contact us at (210) 570-9431 and tell us you have no heat — we'll do our best to get a technician out the same day.
My furnace is running but not heating — what could it be?
Most commonly: a tripped limit switch from overheating (check your filter first), a faulty ignitor, or a gas pressure issue. Could also be a dirty flame sensor that's shutting the burners down after ignition. These all require a technician to diagnose properly.
Should I repair or replace my furnace in San Antonio?
General rule: if the repair costs more than half the replacement price and the unit is over 12-15 years old, replacement is usually better economics. Our team will give you an honest read and walk our customers through the actual numbers — lower energy bills and restored home comfort are part of the calculation too. We are not trying to upsell new equipment if a repair makes sense.
Is a furnace that smells like burning dangerous?
A burning smell when the furnace first turns on for the season is usually dust burning off — normal. A persistent burning smell, especially anything metallic or chemical, is not normal. Turn the unit off and call us. A cracked heat exchanger can produce carbon monoxide.
Do you cover all San Antonio zip codes?
Yes, all of them. No area premium for any part of the city — west side, east side, south, Medical Center, Stone Oak, it's all the same rate and same crew.
What HVAC brands are most common in San Antonio homes?
We see a lot of Trane and Carrier in established neighborhoods, Lennox in 1990s-2000s construction, and Goodman in more recently built communities. We service all of them.
