“Up on the Backbone the power goes out for hours. Moorhead put in a Generac sized for the well and AC, and the last outage we barely noticed. They actually drove all the way out, too.”
The first real cold front hits Fischer 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 Fischer 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 Fischer 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 are built for the view, and all that glass on an exposed ridge is a serious cooling load. We right-size the system and correct airflow so a beautiful room is also a comfortable one.



From the ridgetop homes along the Devil's Backbone to the ranch acreage around Fischer Store, we make the drive out here. A few of the areas:
“Up on the Backbone the power goes out for hours. Moorhead put in a Generac sized for the well and AC, and the last outage we barely noticed. They actually drove all the way out, too.”
“Old panel, long service run, lights flickering. They found the voltage drop, upgraded the panel, added surge protection. Knew the rural stuff cold and were fair about it.”
“Propane furnace quit in a cold snap and we are about as far out as it gets. They came, fixed it, did the CO check, flat price. Grateful somebody reliable covers Fischer.”
Tell us what the system's doing and we'll get right back to you — usually same day, anywhere in Fischer. Prefer to talk? Call (830) 587-5790, day or night.
