Furnace Repair in Houston, TX

Furnace Repair in Houston, TX

Furnace repair in Houston typically costs between $150 and $450 for most common failures, with the work often completed the same day. That range covers the parts and labor for things like ignitor replacement, flame sensor cleaning, blower motor caps, and pressure switch swaps. If you’re calling around because your furnace quit overnight or is short-cycling during a cold front, call Dalton Heating & Air Houston at (903) 494-7686 and we’ll give you a written price before any work starts.

We’re a Garrison Partners company, operating under The Garrison Standard since 2003. That means every repair call includes a written price up front, a written guarantee on the repair itself, and a free return visit if the work doesn’t hold. Our Heating & Furnace in Houston page covers the full scope of what we do, but this page gets specific about furnace repair: what it costs, what breaks most often, and exactly who shows up at your door.

The technician you’ll meet is background-checked and uniformed. You’ll know their name before they arrive. They service nine major residential HVAC brands including Carrier, Goodman, and Lennox furnaces, and they’ll explain the problem in plain terms before turning a single screw.

When You Need Furnace Repair

Houston furnaces sit idle for eight or nine months out of the year, then get asked to run hard when a cold snap moves through. That long idle period is why so many furnace failures in Houston happen on the first cold night of the season. Here’s what to watch for:

• Furnace won’t light or stays cold. Most often it’s the ignitor – the part that glows to light the gas. These crack or burn out over time and are one of the most common fixes we make in the Cypress and Katy areas.
• Short cycling – the furnace starts and stops repeatedly. A dirty flame sensor or a failing limit switch usually causes this. The furnace fires, thinks it’s overheating, and shuts down before the house ever warms up.
• Cold air blowing from vents. When the blower runs but the air is cold, it could be the gas valve not opening or the burner failing to ignite. That’s a fuel delivery problem, not a blower problem.
• Loud bangs or rattling when it starts. A delayed ignition can create a small gas buildup that pops when it lights. It’s startling, and it’s a sign the burners need cleaning or the gas pressure needs adjustment.
• Furnace runs but some rooms stay cold. In Houston’s humid climate, rust and dirt buildup on the blower wheel reduces airflow. That’s more common in older homes in the Heights and Spring Branch where ductwork runs through unconditioned attics.
• Gas smell near the furnace. If you smell gas, turn off the furnace, leave the house, and call CenterPoint Energy first. Then call us, and we’ll pinpoint the source and repair it before it runs again.

Note on safety: furnaces burn natural gas and produce carbon monoxide. If you ever smell gas or your CO detector alerts, do not attempt a repair yourself. A trained technician with proper diagnostic tools needs to find and fix the fault.

Our Furnace Repair Process

We use The Garrison Code on every job. It’s not a slogan; it’s the operating standard that Garrison Partners locations have followed since 2003. Here’s how a furnace repair call works with us:

1. You call, a person answers. Live phone support is staffed 24/7. You’ll talk to a real person who takes your information and books a time window. No voicemail queue, no callback wait.
2. The tech arrives inside the window, uniformed and background-checked. You’ll know who’s coming before they show up. The tech introduces themselves and asks about the symptoms you’ve noticed before touching the furnace.
3. Diagnostic, then written price. The tech inspects the furnace, identifies the failed part or fault, and writes down the exact price for the repair. You approve the number before any work begins. If you don’t like the price, you pay only the diagnostic fee and we’re on our way.
4. Repair done by the book. The fix gets made using manufacturer-spec parts where applicable, and the tech explains what failed and why in plain language. Trade terms get translated – for example, a “limit switch” is the safety sensor that trips when the furnace gets too hot.
5. Test, verify, and clean the site. The furnace gets cycled multiple times to confirm it runs correctly. The work area is left clean. You get a written guarantee covering the repair for a full year.

Furnace Repair Pricing in Houston

Here’s the honest math on furnace repair in Houston. Most repairs fall between $150 and $450. Some smaller fixes run under $150, and some larger ones – like a blower motor replacement – can push past $500. Here’s the breakdown by part type:

Repair Type	Typical Cost Range in Houston
Flame sensor cleaning/replacement	$90 – $160
Ignitor replacement	$150 – $280
Pressure switch	$120 – $220
Gas valve replacement	$250 – $500
Blower motor capacitor	$110 – $200
Blower motor (full replacement)	$350 – $700
Control board	$250 – $550
Thermocouple (older standing-pilot furnaces)	$100 – $180

What affects the cost? The part itself, whether it’s in stock locally or needs ordering, and the age of the furnace. Older units – 15 years and up – sometimes require creative sourcing for parts, which adds time but not markup. In Houston, where salt air near Galveston Bay can corrode electrical connections, we also see more wiring repairs on coastal-side homes than in inland neighborhoods like Tomball or Conroe.

Every quote is a written price before work begins. No pricing shifts at the door, no surprise add-ons. We’d rather lose a job than start one without you knowing the exact number. That’s The Garrison Standard, and it’s been the company’s operating rule since 2003.

Furnace Brands We Repair

Our techs are factory-trained on nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Houston, the furnaces we see most often in repair calls are Carrier, Goodman, and Lennox units. Goodman is especially common in Houston subdivisions built after 1995, while Carrier and Lennox show up frequently in older neighborhoods like Meyerland, Bellaire, and the Memorial Villages.

Brand matters for parts availability. A Carrier gas valve and a Goodman gas valve are not interchangeable, and installing the wrong part creates a safety risk. Our trucks carry common Carrier, Goodman, and Lennox parts so we can often complete repairs in one visit.

Why Homeowners Call Dalton Heating & Air

We get called after other contractors have already let someone down. The homeowner waited through a four-hour window, watched a tech quote one number and then write a different one on the invoice, or found sheet metal screws and wire clippings left on the floor. We don’t chase the lowest bid. We compete on discipline.

Every repair comes with a written guarantee. Full stop. If the repair fails within a full year, we come back at no charge – that’s the 365-Day Done Right Promise, and it’s included on every service call without any upgrade fee. If your furnace quits again within that year, you don’t pay a second visit fee, you don’t pay for the part, you don’t pay anything.

We’re a Garrison Partners company, which means we operate under The Garrison Code: arrive inside the stated window, price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year. It’s not a marketing line. It’s the standard our techs are evaluated against on every job.

FAQs – Furnace Repair

How much does furnace repair cost in Houston?

Most furnace repairs in Houston run $150 to $450 depending on the failed part; ignitor replacement typically costs $150 to $280, while a gas valve runs $250 to $500. We put the exact price in writing before any work starts, and the diagnostic fee is applied toward the repair if you approve it. Call (903) 494-7686 to schedule, and the tech will give you a written number on site.

Can you fix my furnace the same day?

Yes, we handle same-day furnace repair calls throughout Houston, and our trucks carry common Carrier, Goodman, and Lennox parts so many repairs are completed in a single visit. Live phone support is staffed 24/7, so if your furnace quits on a cold night, call (903) 494-7686 and a real person will schedule the first available window.

Is it cheaper to repair or replace a furnace?

If the repair costs less than roughly 30% of a new furnace’s installed price and the unit is under 15 years old, repair typically makes more sense; if the heat exchanger is cracked or the repair cost approaches half of what a new one would cost, replacement is the better call. Our techs will give you both paths with prices in writing and let you decide. We don’t push replacement on a furnace that only needs a $200 repair.

How do I know if my furnace is unsafe to run?

Any gas smell, visible soot around the burner area, CO detector alarms, or persistent headaches when the furnace runs are signs to shut the unit down and call a professional immediately; a cracked heat exchanger is the serious one because it can leak carbon monoxide into living space. Our techs can test for cracked heat exchangers on every service call and will show you exactly what they find.

Do you charge extra for weekend or emergency furnace repair?

We charge a diagnostic fee that’s the same whether it’s Tuesday afternoon or Sunday night; if you approve the repair, the diagnostic fee is applied toward the total, so you’re not paying two separate costs. Calls are answered by a live person 24/7, which means someone can actually tell you what the next available window is rather than putting you in a callback queue.
