The first real cold front hits Bulverde 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 Bulverde 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 Bulverde 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.
Hill Country homes love their views, and all that west-facing glass is a cooling load the builder may have underestimated. We correct airflow, add zoning, and right-size systems for homes that bake in the afternoon sun.



From the new master-planned communities along US-281 to the ranch acreage off SH-46, we cover Bulverde and the surrounding 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.

“Out on acreage off 46 and the power drops a lot. They put in a Generac sized for the well pump and AC. Game changer, and they were upfront on price the whole way.”
“Added an EV charger and surge protection. They checked the panel properly, pulled the permit, clean install. Easy to deal with and fair.”
