Roy Jaramillo, Owner
San Antonio local since 2008
Castroville is a small historic community about 25 miles west of downtown San Antonio in Medina County. It's a longer drive, but we serve it at the same pricing and same standard as everywhere else. The older homes and rural character of the area come with specific HVAC considerations that we're familiar with from years of serving the broader region.
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 Castroville and Medina County. 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 Castroville, TX
We serve Castroville and surrounding Medina County. One of the most historic communities near San Antonio, and one we're glad to serve.
Castroville has a historic downtown with homes dating back over a century, plus surrounding rural properties and ranches with more modern construction. Historic homes in Castroville often lack the attic space and infrastructure for conventional split system installation. Mini-splits are frequently the more practical solution in these properties. Well water is the norm on rural properties, which affects condensate system behavior and disposal options.
Rural properties in the Castroville area commonly have propane heating rather than natural gas, which affects furnace options for repair and replacement. Agricultural dust and debris accumulate around outdoor units faster than in suburban settings. We check unit clearances and coil condition carefully in rural Medina County properties. Access to some properties for parts delivery can be a factor we account for in scheduling.
All service in Castroville 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 Castroville?
For heating emergencies in Castroville 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 Castroville?
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.
Is there a service fee for coming to Castroville?
Our standard diagnostic fee applies, same as any location. Castroville is within our service territory and we make the drive.
My Castroville property uses propane for heat. Can you work on that?
Yes. We service and install propane furnaces as well as natural gas systems. We verify fuel type and BTU requirements before recommending any equipment.
