Why Dalton Heating & Air Houston Is Houston’s Preferred Furnace Repair Company
Houston homeowners have been through enough with contractors. The no-shows, the price that changes at the door, the crew that leaves the burners half-wired. Dalton Heating & Air operates under The Garrison Standard, which has governed every job since 2003: arrive inside the stated window, put the price in writing before starting, do the job by the book, leave the site clean, and stand behind the repair for a full year. That’s not marketing language. It’s a binding operational code.
Marco Benitez leads the team here in Houston, and he runs it the way a service company should run. Our techs are factory-trained on nine major residential brands, including Carrier, Trane, Lennox, and Goodman. They show up in uniform, identify themselves, and walk you through what they found before they do anything. You know who is coming before they arrive. That matters when a stranger is going to be in your house.
Houston homeowners call us for a lot of reasons, but the most common is this: they want a mechanic who treats the house like it’s their own. No scare tactics, no upselling, no mystery surcharge at the end. The price is on the table before the first screw comes out, and if the repair fails inside a year, we’re back at no charge. That’s the 365-Day Done Right Promise, and it applies to every repair we make in Houston.
We also know Houston’s housing stock. Single-family homes built from the 1970s onward dominate the metro, many with slab foundations and attic-installed horizontal furnace units. Older neighborhoods inside the Loop, like Montrose and the Heights, have pier-and-beam homes with tighter mechanical closets and older ductwork. What works in a 2,200-square-foot Katy house doesn’t always translate to a 1940s bungalow in Idylwood. Our techs have seen both, and they check the air filter, not just the board.

Styles & brands we work with
Boiler Repair in Houston
Boiler repair in Houston is less common than furnace repair, but plenty of older homes in the Greater Heights, Garden Oaks, and Oak Forest still run hydronic heat, and those systems need a specific touch. A boiler heats water instead of air, circulating it through radiators or baseboard heaters. When a boiler fails, it’s usually the circulator pump, the expansion tank, or a thermocouple that died, and most boiler repairs in Houston run $150 – $700 for parts and labor. Because boilers are rare in this market, you want a tech who has actually worked on them, not just watched a video.
Circulator Pump and Expansion Tank Failure
A circulator pump moves heated water through the loop. When it seizes, the boiler fires but the radiators stay cold. Expansion tanks fail when the internal bladder ruptures, and that sends system pressure climbing until the relief valve starts spitting water. Both are routine replacements, and both should be caught during an annual tune-up before a cold snap. If you’re hearing a hum but no heat from your radiators, call us before the temperature drops below 40°F.
Heat Exchanger and Gas Valve Checks on Boilers
Furnace heat exchangers rust when combustion gases condense unevenly. Boilers have the same problem, and because Houston humidity keeps mechanical rooms damp, corrosion sets in faster here. We pressure-test and visually inspect every heat exchanger on every boiler repair. If it’s cracked, we shut it down and quote the replacement the same day. Carbon monoxide doesn’t care if the system is a boiler or a furnace.
Gas Furnace Repair in Houston
Gas furnace repair in Houston is what most of our winter calls end up being. A gas furnace burns natural gas, and the failure points are predictable: an ignitor that cracks, a flame sensor that gets coated in carbon, a gas valve that won’t open, or a blower motor that finally gives out. The most common gas furnace repair in Houston runs $150 – $450 for ignition components and sensors. Blower motor replacements land in the $400 – $700 range depending on the motor type. Either way, the diagnosis comes first, and the price is in writing before we replace anything.
Ignitor and Flame Sensor Failures
The hot-surface ignitor is a ceramic element that glows to light the burner. When it cracks, the furnace tries to start, the control board times out, and you get cold air or nothing at all. The flame sensor proves the burner is actually lit, and after a few seasons of Houston’s humid air, it corrodes and sends a false “no flame” signal. Cleaning a flame sensor takes minutes. Replacing an ignitor takes about an hour. Both are simple, common, and cheap compared to the alternative.
Gas Valve and Blower Motor Repairs
When the gas valve won’t open, the unit never fires, and the homeowner is left checking the thermostat over and over. Gas valve replacement is a straightforward parts swap, but it has to be done by someone who understands gas pressure and safety shutoff. A blower motor that grinds or stops means no air moves through the ductwork, even though the burners are lit. That’s when heat builds up inside the cabinet and trips the high-limit switch. If you smell anything like gas near the furnace, shut the unit off at the breaker and the gas line valve if you can do so safely, evacuate, and call us. Gas work should only be done by a trained professional.
Trusted Brands We Service in Houston
We repair every major residential furnace brand you’ll find in Houston, including Carrier, Trane, and Lennox. Our techs are factory-trained on these names and stock common parts on the trucks, so a simple ignitor or flame sensor replacement doesn’t require a second visit. Goodman furnaces are everywhere in Houston’s suburban subdivisions, especially in slab-foundation homes from the 1980s and 1990s, and we carry a deep stock of Goodman ignitors, pressure switches, and control boards for the models we see most. That means less waiting and a faster fix for Houston homeowners. In a market where attic installations are the norm, a tech who knows how to work in a 140°F attic in July without breaking anything is the difference between a one-visit repair and a three-week saga.
Common Furnace Repair Problems We See in Houston Homes
- Flooded condensers and heat pumps after bayou flooding. In Meyerland and Braeswood Place, repeated flooding from Brays Bayou has pushed many homeowners to install flood-proof curbs and corrosion-resistant coil coatings on outdoor condensers. So a furnace repair call here often begins with checking whether a flooded condenser was properly isolated and dried before restart, something rarely seen in drier Texas cities.
- Clogged condensate drains from 200+ days of high humidity. Houston furnaces run nearly year-round, and the heavy moisture load causes evaporator coils to rust and condensate drains to clog far more frequently than in other Texas markets. When the drain backs up, water pools in the drain pan and can short out the control board or rust the heat exchanger.
- Slab-foundation homes with attic-installed horizontal units and rusted heat exchangers. Most Houston homes built since the 1970s have the furnace laid on its side in the attic. A clogged condensate drain backs up into the heat exchanger, accelerating rust and eventually cracking the exchanger. A cracked exchanger leaks carbon monoxide, and it has to be caught before it becomes dangerous. Since 2003, The Garrison Code has required a visual heat exchanger inspection on every furnace call.
- Power surge damage to capacitors and control boards after Gulf Coast storms. After a lightning strike or a power surge during a thunderstorm, a furnace’s capacitor or contactor fails silently. The homeowner doesn’t know anything is wrong until the first cold front in November or December, when the furnace won’t kick on. We see a wave of these calls every year after the first real cold snap in Houston.

FAQs About Furnace Repair in Houston
No. Never switch on a flooded condenser without a full inspection first. Floodwater leaves silt on the condenser coil, and moisture gets into the electrical compartment, swelling capacitors and corroding contactors. If you power it up like that, the compressor can short out and seize within days, turning a $300 repair into a full system replacement. We were called to a 1990s-era home in Meyerland where the homeowner had tried to restart their Trane heat pump after Harvey floodwater receded. Our tech found the condenser coil caked with silt and the capacitor swollen from moisture. We replaced the capacitor, flushed the coil, and verified the refrigerant charge, then recommended a corrosion-resistant coating and a raised curb to prevent the next flood from killing the compressor. Call (903) 494-7686 before you touch that breaker.
The humid Houston air is the culprit. An attic furnace has a condensate drain that carries away the water it pulls from the air. With 200+ days of high humidity, that drain clogs more often here, and when it backs up, water sits against the heat exchanger, causing rust that eventually cracks it. A cracked exchanger leaks carbon monoxide. We catch this early with a visual inspection on every tune-up and repair call.
Very likely. When power comes back after an outage, the surge can fry the furnace’s control board or capacitor, depending on where the spike hits. The furnace may have been fine before the outage and dead after it. We see a wave of these calls every time a Gulf storm rolls through Houston. Call us at (903) 494-7686 and we’ll send a tech to test the board, the capacitor, and the transformer, then give you a written quote for whatever failed.
For a gas furnace, you need a generator rated for the furnace’s blower motor draw plus the control board, which typically means 3,000 to 5,000 watts for most single-family systems. But the real answer is: you need a cord, a transfer switch, and a plan. A gas furnace’s blower motor pulls about 600 to 900 watts, but the startup surge can double that. Go with a 5,000-watt generator to be safe, and never backfeed through a dryer outlet. We repair furnaces all winter after freeze events and power outages across Houston, and we can help you spec the right setup. For an exact quote on a furnace inspection before you trust a generator to run it, call us.
Yes. Older pier-and-beam homes in Houston, especially inside the Loop in neighborhoods like the Heights and Montrose, often have mechanical spaces that were never designed for modern furnace dimensions. We can install horizontal units in low-clearance attics, or switch you to a ductless mini-split if the existing ductwork isn’t worth salvaging. The Garrison Standard applies either way: written price before any work starts, and a written guarantee on the installation. Call (903) 494-7686 and we’ll come take measurements.
