HVAC Company in Somerset, TX
Dalton Heating & Air is the HVAC company Somerset homeowners call when a system fails in July or won’t fire in January. Most homes here were built to handle South Texas heat, but the combination of aged ductwork, hard water, and summer runtimes measured in months means repairs come due at the worst possible time. We service all nine major residential brands, put every price in writing before work starts, and back every repair with a written one-year guarantee. Call (361) 306-9515 when you need a technician who shows up inside the window.
Why Somerset Homes Are Different
Somerset sits far enough south of San Antonio that the summer heat is relentless from May through September, and the humidity off the Gulf makes air conditioners work harder than they would in drier parts of Texas. That means coils corrode, capacitors fail under the strain of constant cycling, and condensate drains clog with algae at a rate that surprises homeowners who moved here from up north. Houses in Somerset run the full age range – from rural properties with original 1990s equipment to newer subdivisions where builders installed the cheapest compliant unit they could find and moved on.
The other factor is water. Somerset draws on the Carrizo-Wilcox Aquifer, and the mineral content in that water shortens the life of anything it touches. For HVAC, that shows up in evaporator coils that scale over, drain pans that rust through, and hard-water deposits inside humidifier lines. We keep replacement parts for the most common failure points stocked in our San Antonio dispatch location, which cuts a half-day off most Somerset repairs simply because the part isn’t coming from Dallas or Houston.
Our Main Somerset Services
Somerset homeowners call us for three jobs more than anything else: diagnosing an AC that’s blowing warm, installing a heat pump that actually fits the house, and repairing a furnace that won’t hold a flame. Each service has its own Somerset page with pricing, specific sub-jobs, and what to expect.
AC Repair in Somerset
When your AC quits in Somerset in August, the house gets uncomfortable in under two hours. Most calls we run here are capacitor failures, refrigerant leaks, and seized condenser fan motors – all repairable same day if the part is on the truck, which it usually is for a Trane, Lennox, Goodman, or Rheem. We diagnose first, hand you a written price, and don’t touch a tool until you approve it. See full pricing and what a repair visit includes on our AC Repair in Somerset page.

Heat Pump Installation in Somerset
Heat pumps make sense in Somerset because winters are mild enough that the unit rarely needs backup heat strips, and summers are hot enough that a properly sized heat pump cuts cooling costs versus an older straight-cool condenser. Sizing matters more here than it does in a cooler climate – undersize it and the system never drops humidity, oversize it and it short-cycles through the hottest weeks. We run the load calculation before quoting, and the price is fixed in writing before installation day. Details on Heat Pump Installation in Somerset.

Furnace Repair in Somerset
Somerset doesn’t get the hard freezes that cities further north see, but furnaces here still fail exactly when the temperature drops – usually a dirty flame sensor, a failed ignitor, or a cracked heat exchanger on older units. A cracked heat exchanger is a safety issue, not a repair delay: we red-tag it and walk you through replacement options the same day if you want. Written price before we start, written one-year guarantee when we finish. Read more on the Furnace Repair in Somerset page.

Brands We Service in Somerset
We’re factory-trained on nine major residential HVAC brands, and in Somerset we see more Trane, Lennox, Goodman, and Rheem than anything else. The parts trucks carry the common capacitors, contactors, flame sensors, and thermostats for those four brands, so most repairs finish in one visit. Full brand list on our brands page.

What pushes a repair toward the top of the range in Somerset is usually access: a condenser buried behind overgrown brush, an attic furnace with a tight crawl, or a system so old the replacement part is no longer made and requires a retrofit. The price you approve before work starts is the price you pay – no door-knock surcharge, no “we found something else” add-on that wasn’t discussed first. That’s The Garrison Standard.

FAQs About HVAC Company in Somerset
Most Somerset calls get a technician on site within two hours. Our dispatch is staffed by a live person at (361) 306-9515 around the clock, so you’re not leaving voicemails while the house heats up. We’ll give you a window when you call and the technician calls ahead when they’re en route.
Most Somerset HVAC replacements require a permit, which we pull as part of the job. Repairs generally don’t. If your job does need one, it’s included in the written quote – not billed as a surprise line item after work starts.
Only if we show you the problem, explain it in plain English, and you approve the revised price in writing before we touch it. The price on the original ticket stands for everything we quoted. That’s the point of written upfront pricing – it protects you from exactly the scenario where a tech finds a “bonus” issue and doubles the bill. Call (361) 306-9515 for a free estimate on any HVAC work in Somerset.
