Heating Repair in San Marcos
Whether you run a gas furnace, a heat pump, or propane out on Hays County acreage, here is what we see when the heat quits.
Furnace Will Not Ignite
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.
Heat Pump Not Keeping Up
A lot of San Marcos 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.
The Carbon Monoxide Check
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.
Propane and Rural Setups
No natural gas out on the acreage means propane furnaces and heat pumps, which we service routinely. We come prepared for rural Hays County setups, not just city gas lines.
Why San Marcos Homes in Particular
Master-planned communities like Blanco Vista and the 55-plus Kissing Tree brought a wave of new construction with builder-grade systems. Same story as everywhere — sized to a price, weak in a Texas August. We run a load calculation and fix the airflow once the warranty runs out.
