The first real cold front hits Schertz 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 Schertz 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 Guadalupe 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 Schertz 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 Guadalupe County setups, not just city gas lines.
When a line goes down along the 3009 corridor, the whole subdivision sits in the dark. We are an authorized Generac dealer and we size the standby unit to actually carry your air conditioning - not just the fridge and a couple of lights. Prices published before install.



From the new construction in The Crossvine to the established streets near Randolph, Schertz is one of our busiest next-door service areas. A few of the spots we cover:
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.

“Bought an older place near Randolph and the inspector flagged the panel. Justin's crew swapped it, pulled the permit, and had us up to code in a day. Fair price, no drama.”
“AC quit on a Saturday and they were at the house within a couple hours - being right down the road in Seguin clearly helps. Capacitor, fixed on the spot, exactly the price quoted.”
Tell us what it's doing and we'll get someone out fast - same day in most cases, anywhere in Schertz. You get the price in writing before any work starts. Or call (830) 587-5790, day or night.
