- Dispatch and scheduling are coordinated from our San Antonio office; crews are in Somerset daily.
Why Dalton Heating & Air Is Somerset’s Preferred Furnace Repair Company
Somerset homeowners call us after dealing with no-shows and quotes that changed at the door. That’s the reputation we respond to. Every job under The Garrison Standard includes a written price before any work begins, a written guarantee on every repair, and a free second visit if the repair fails inside the guarantee window. It’s not an upgrade. It’s the baseline.
Our response time to Somerset neighborhoods like Country View Estates, Somerset Meadows, and the older homes along Main Street runs inside two hours for no-heat calls during cold weather. For non-emergency repair, we schedule a firm window and show up inside it. You’ll know the tech’s name before they arrive. They’ll wear a Dalton uniform and cover the work area before opening the furnace.
Marco Benitez runs our team, and he’s strict about one thing: if a tech can’t explain the repair clearly enough that a homeowner could repeat it to a neighbor, the job isn’t done explaining. That standard applies on every Somerset call. The techs here are factory-trained on nine major residential brands and carry enough common parts on the truck to complete most repairs in a single visit.
Boiler Repair in Somerset
Boiler repair in Somerset is less common than furnace work but still shows up in older homes along Main Street and the rural properties off Somerset Road, where hydronic systems were installed before forced-air became the default. A boiler that won’t hold pressure, makes banging sounds when it fires, or leaves radiators cold on one side of the house needs a trained hand, not a parts cannon. We diagnose the circulator pump, pressure relief valve, expansion tank, and gas train before quoting a repair. Most boiler work here runs inside the same $150 – $700 range as furnace repair, which is why we quote a written price before any part gets ordered.
Heat Exchanger Testing on Boilers
A cracked heat exchanger on a boiler in Somerset can send carbon monoxide into the living space, especially in tighter, older homes with sealed-up windows during a cold snap. Our techs test with a combustion analyzer on every boiler call, not just when the homeowner reports a smell. If the exchanger fails inspection, we quote a replacement or a system swap with the repair-versus-replace math laid out on paper.
Gas Valve and Ignitor Replacement
A boiler that fires but shuts down seconds later usually points to a failing gas valve or a weak ignitor. These are common on units that ran fine all fall and then got pushed hard on the first hard freeze. We keep replacement gas valves and ignitors stocked for the boiler brands Somerset homes actually have, so the repair usually happens same visit.
Gas Furnace Repair in Somerset
Gas furnace repair in Somerset makes up the bulk of our winter calls, and the pattern is consistent: units that coast through mild stretches short-cycle, and then the first real freeze pushes them into failure. You’ll hear the furnace click on, run two or three minutes, shut down, and repeat. That’s short-cycling, and in Somerset it’s usually a failing capacitor, a dirty flame sensor, or an overheating limit switch. We test all three on the first visit. Pricing falls inside the $150 – $700 range depending on which component failed, and the repair is guaranteed in writing for a full year.
Blower Motor and Capacitor Work
Older Carrier, Lennox, and Goodman furnaces in Somerset sit idle for months, and when the first 28-degree morning arrives, the blower motor gets asked to do a year’s work in a week. Capacitors fail first. Then the motor bearings. We test the capacitor under load and check amp draw on the blower motor before condemning either. Replacing a run capacitor is a $150 – $300 job. A full blower motor replacement runs higher, up to $700, and we’ll show you the motor’s actual amp draw before you approve the work.
Heat Exchanger Inspection
Gas furnace heat exchangers in Somerset don’t usually fail from corrosion the way they do in Houston’s humidity. Here, the stress comes from short, low-demand heating cycles that never let the exchanger fully expand. The metal fatigues over time, and microfractures form along the welds. Our techs inspect with a camera on every furnace repair call, not just when the unit trips a roll-out switch. If the exchanger shows unsafe cracks, we stop the work and walk you through repair versus replacement with real numbers on the page.
Trusted Brands We Service in Somerset
We see a lot of Goodman units in Somerset’s newer subdivisions and plenty of Rheem and York systems in the older homes along Somerset Road and Main Street. Daikin shows up in some of the higher-end properties east of town. We’re factory-trained on all four brands and a few more, and we keep their common furnace parts on our trucks so a Somerset repair doesn’t turn into a two-visit job waiting on a shipment. If you can tell us the brand and model from the sticker inside the furnace cabinet, we’ll arrive prepared. We stock parts for all nine major residential brands we service, which means fewer return trips and a faster fix when the temperature is dropping.
Common Furnace Repair Problems We See in Somerset Homes
- Short-cycling on cold mornings. Furnaces sized for mild South Texas winters get confused by a hard freeze and start cycling on and off. The fix is sometimes a sensor, sometimes a full load calculation that reveals the system was oversized from the day it was installed.
- Blower motor and capacitor failures on older Carrier, Lennox, and Goodman units. Long idle stretches followed by sudden demand wear out capacitors and motor bearings faster than steady use. We test both before quoting a replacement.
- Heat exchanger fatigue from low-demand heating. Somerset’s mixed heating profile means exchangers don’t always reach full operating temperature before the thermostat satisfies. That thermal stress accumulates over years and shows up as cracks along welds.
- Gas valve and ignitor failures on the first freeze. A gas valve that sat untouched all summer can stick, and an ignitor that worked in March can crack on the first 30-degree morning. We keep replacements stocked for the brands Somerset homes actually have.
Somerset sits in the transition zone between Gulf Coast humidity and drier South Texas brush country. That’s why winter furnace calls here swing between two failure patterns: short, mild heating cycles that leave blower motors and heat exchangers under-cycled, and cold snaps that push units harder than their South Texas install ever assumed. We got a call in Somerset proper off Somerset Road where a 2008 Carrier gas furnace was short-cycling on a cold snap. The homeowner had been told it needed a full replacement. Our tech tested the capacitor and blower motor, found a failing run capacitor and a heat exchanger showing normal wear, and repaired it for less than a new system down payment. Then he ran a load calculation that showed the existing tonnage was actually oversized for the home. That’s the Somerset difference in one job: the right diagnosis, the right repair, and no replacement pitch when the math doesn’t support it.

FAQs About Furnace Repair in Somerset
Repair first, unless the heat exchanger has failed or the unit is over 18 years old with multiple failing components. Most short-cycling in Somerset is a $150 – $300 fix: a capacitor, flame sensor, or limit switch. We’ll test the system, run a load calculation if the sizing seems off, and lay out repair costs versus replacement costs in writing. You make the call with real numbers, not a sales pitch. Call (361) 306-9515 to schedule a diagnostic.
It tells you whether your furnace was ever the right size. Somerset homes built for Gulf Coast mildness often got oversized furnaces, which short-cycle and stress the heat exchanger. A proper Manual J load calculation shows whether the existing tonnage matches the actual heating load. If it doesn’t, the right repair might be different from the one another company quoted. This is part of our diagnostic process on any repair where sizing is in question.
Most furnace repairs in Somerset run between $150 and $700. Minor work like flame sensor cleaning or capacitor replacement sits at the low end. Blower motor, gas valve, or heat exchanger repairs push toward the top. You’ll get the exact price in writing before any work starts, and the repair is guaranteed for a full year. Call (361) 306-9515 for a free estimate.
Yes. We service both boiler systems and gas furnaces across Somerset, including the older homes on Main Street with hydronic heat and the newer forced-air systems in the subdivisions. Boiler work covers circulator pumps, pressure relief valves, expansion tanks, gas trains, and heat exchangers. Gas furnace work covers ignitors, gas valves, blower motors, capacitors, and heat exchanger inspection. Both carry the same written guarantee.
SEER2 is the updated efficiency rating for HVAC equipment that took effect in 2023, using more realistic testing conditions than the old SEER number. A higher SEER2 rating means lower cooling cost per summer month, but the heating side depends on your furnace’s AFUE percentage. In Somerset, where the heat pump handles most winter days and the furnace only fires on cold snaps, a moderate SEER2 with a high-quality furnace often makes more financial sense than a top-efficiency heat pump. We’ll show you the math on your actual bill, not a brochure number.
When your furnace dies on the first cold morning in Somerset, you need a company that answers the phone, shows up inside the window, and puts the price in writing before any work starts. That’s how Dalton Heating & Air operates on every job, no exceptions. Call (361) 306-9515 and Marco’s team will get you straight.
