The first real cold front hits Smithson Valley and the furnace will not light. We carry ignitors and flame sensors on the truck and check the heat exchanger for carbon monoxide on every visit.

South Texas heat gets the headlines, but a Smithson Valley cold snap finds every furnace that sat untouched since last winter. The common failures - an ignitor, a flame sensor, a tripped limit - are parts we carry.
And we never close a heating call without checking the heat exchanger for cracks. Carbon monoxide is not something to guess on.
Call (830) 587-5790Whether you run a gas furnace, a heat pump, or propane out on Comal County acreage, here is what we see when the heat quits.
Usually a failed hot-surface ignitor or a dirty flame sensor - both common, both on the truck, both a same-visit fix. We test the whole ignition sequence rather than swapping parts blind.
A lot of Smithson Valley homes run heat pumps, which work differently than a furnace. Low charge, a stuck reversing valve, or a failed defrost control all show up as "not enough heat." We diagnose the actual cause.
On every heating visit we inspect the heat exchanger for cracks. A cracked exchanger can leak CO into the house, and it is the one furnace problem we will tell you to stop using the system over. Safety is not a flat-rate line item - it is the job.
No natural gas out on the acreage means propane furnaces and heat pumps, which we service routinely. We come prepared for rural Comal County setups, not just city gas lines.
Acreage living means barns, shops, and workshops, each wanting power the original panel never planned for. We add circuits, upgrade panels, and install surge protection to guard it all on the ERCOT grid.



From the established acreage off Smithson Valley Road to the newer builds nearby, we cover Smithson Valley and the surrounding Comal County Hill Country. A few of the areas:
When Gloria wanted a second opinion on her San Antonio home's aging system, Moorhead Service Company sent out technician Robert Rodriguez. Robert took the time to inspect the equipment, patiently explain what was really going on, and perform a thorough cleaning to help the system run at its best. Gloria got straight answers and honest service - exactly what every San Antonio homeowner deserves from an HVAC company.

“Newer build, hot upstairs every afternoon. They measured the load and fixed the airflow instead of pushing a bigger unit. Honest and fair, drove out without complaint.”
“Wired the shop and upgraded the panel, added surge protection. Clean work, pulled the permit, exactly the quoted price. Good people to deal with.”
