The first real cold front hits Luling 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 Luling 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 Caldwell 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 Luling 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 Caldwell County setups, not just city gas lines.
Luling is one of the nearer towns on our extended map - a straight shot up US-90 from Seguin - so the drive is shorter and same-day is more often on the table. Call to confirm and we will tell you when.



From the historic downtown to the homes along the river and US-90, we reach Luling on the nearer extended run. 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.

“Place near the river was always muggy. Dehumidifier and duct sealing fixed it. They came out from Seguin quick since we are close, and the price matched the quote.”
“Added a shop and a charger and the old panel could not take it. They upgraded it and added surge protection. Honest, straightforward work.”
