“Our Alsatian home is a landmark and we were terrified of someone wrecking it. Moorhead modernized the wiring with real care, kept everything original-looking, and pulled the permit. Rare to find that respect.”
The first real cold front hits Castroville 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.
Thanks for reaching out. We've got your request and we'll be in touch shortly, usually the same day. Need us right now? Call (830) 587-5790 — we're open 24/7.
CO check every visit
South Texas heat gets the headlines, but a Castroville 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 Medina 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 Castroville 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 Medina County setups, not just city gas lines.
Castroville is a real distance west on US-90. We give you an honest scheduling window rather than overpromise, and the same careful, flat-rate work we do at home. Call to confirm and we will tell you when.



From the historic Alsatian district along the Medina River to the homes just outside it, we reach Castroville on the extended run. A few of the areas:
“Our Alsatian home is a landmark and we were terrified of someone wrecking it. Moorhead modernized the wiring with real care, kept everything original-looking, and pulled the permit. Rare to find that respect.”
“Old home with no ducts in half of it. They put in a mini-split and it is finally comfortable without tearing into the walls. Smart, careful work.”
“House by the river was always muggy. Dehumidifier and duct sealing fixed it. They drove out from Seguin and were honest about the schedule.”
Tell us what the system's doing and we'll get right back to you — usually same day, anywhere in Castroville. Prefer to talk? Call (830) 587-5790, day or night.
