When your furnace quits on a cold Houston night, the problem isn’t just comfort, it’s urgency. A dead heating system in a city that swings from mild to freezing within hours leaves your family in a cold house and your pipes at risk. Furnace repair in Houston typically runs $150 to $700 depending on what failed, and most repairs are completed the same day we arrive. We’re Coldharbour Heating & Air, and since 2003 we’ve been fixing furnaces across Houston with one rule that never bends: the price goes in writing before a single tool comes out. Call (832) 371-9862 and a live person answers, 24 hours a day.
Victor Mancini started this company on the Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails. That last part isn’t optional. Every repair we make carries the 365-Day Done Right Promise. If the furnace fails again inside a full year, we come back and fix it at no charge.

Styles & brands we work with







Furnace Maintenance
Furnace Maintenance is the routine servicing that catches small problems before they become mid-winter breakdowns. In Houston’s climate, furnaces sit idle for months and then get asked to work hard on short notice, so annual maintenance in early fall is the smartest scheduling window. Our maintenance visit runs $80 to $200 and includes inspection of the burner, heat exchanger, electrical connections, and airflow, plus a written report of exactly what we found and what it means.
What the Maintenance Visit Covers
We check the flame sensor, igniter, gas pressure, and safety controls on every visit. We also measure temperature rise across the heat exchanger to catch cracks or blockages early. You’ll get a written list of what’s in good shape, what’s wearing, and what can wait.
Why It Pays for Itself
A clean, adjusted furnace uses less gas and fails less often. The $80 to $200 you spend on maintenance almost always comes back as lower utility bills and avoided repairs. It also keeps your manufacturer warranty valid, since most brands require annual service records.
Heat Pump Repair
Heat Pump Repair covers systems that both heat and cool your Houston home, which is why they work year-round and wear out faster than furnaces alone. When a heat pump won’t switch to heating mode, short-cycles, or blows lukewarm air, it usually points to a refrigerant issue, a failed reversing valve, or a defrost control problem. Repairs here run $150 to $650, and our technicians carry the parts needed for most heat pump fixes on the truck.
Reversing Valve and Defrost Issues
The reversing valve is the part that tells your heat pump whether to heat or cool. When it sticks, you get cold air in heating mode or warm air in summer. Our techs diagnose this with temperature and pressure readings rather than guesswork, and the fix is covered under our 365-day guarantee.
Houston Humidity and Heat Pump Strain
Heat pumps in Houston run almost constantly because they’re the primary source of both heating and cooling. That year-round load shortens component life compared to northern climates. We see fewer heat pump failures in homes that get a spring and fall checkup, which keeps defrost cycles and coil condition from degrading unnoticed.
Heating Repair
Heating Repair covers every type of system that warms your Houston home, whether you have a gas furnace, electric furnace, heat pump, or hydronic setup. When any heating system isn’t producing heat, producing too little, or cycling oddly, the first job is to pinpoint the exact failed component. Heating repairs in Houston run $150 to $650, with full system overhauls reaching $700 in worst-case scenarios. We give you the exact number before starting work, so there’s no surprise at the door.
Diagnosing the Real Problem
We start with the sequence of operation, the order of events your system must follow to produce heat. Watching where the system stops tells us whether the issue is the thermostat, the igniter, the gas valve, the blower, or the control board. That’s faster than swapping parts and hoping, and it’s why most of our heating repairs are done in one visit.
Electric vs. Gas Heating Repairs
Electric furnaces fail differently than gas ones, usually at heating elements or sequencers. Gas systems more often fail at igniters, flame sensors, or gas valves. We’re trained on both, and on the heat pumps that many Houston homes use as their primary heating source, so the diagnosis starts in the right place from the start.
Boiler Repair
Boiler Repair in Houston is less common than furnace work, but plenty of older homes in West University Place and the Heights still heat with hydronic systems. A boiler heats water and circulates it through radiators, and when it fails, the symptoms are cold radiators, knocking pipes, or pressure that won’t hold. Boiler repairs cost $150 to $700 depending on whether the problem is the circulator pump, expansion tank, zone valve, or the burner itself.
Circulator Pump and Zone Valve Failures
Most boiler breakdowns in Houston come from circulator pumps that stop moving water or zone valves that won’t open. When the pump fails, you’ll hear the boiler fire but feel cold radiators. Zone valve issues usually show up as one room or floor staying cold while the rest of the house heats.
Boiler Pressure and Expansion Tanks
Houston’s temperature swings put stress on boiler pressure controls and expansion tanks. If your pressure gauge spikes when the boiler runs, or water drips from the relief valve, the expansion tank has likely failed. We carry replacement tanks and pressure valves on the truck, which keeps boiler repairs to one visit in most cases.
Gas Furnace Repair
Gas Furnace Repair is the most common heating service call we make in Houston. A gas furnace burns natural gas to heat air that gets pushed through your ducts, and when it fails, the usual culprits are the igniter, flame sensor, gas valve, or pressure switch. Gas furnace repairs run $150 to $700, with igniter replacements typically falling between $150 and $280, parts and labor included.
Igniter and Flame Sensor Failures
The hot surface igniter is the part that lights the gas, and it’s a wear item. In Houston’s humid air, igniters can corrode faster than in drier climates, which is why we see so many of them in service calls. The flame sensor, which tells the furnace the gas actually lit, gets coated with carbon over time and can usually be cleaned rather than replaced.
Safety First on Gas Systems
Gas furnaces burn fuel inside your home, so any repair involving the gas valve, burners, or venting should be handled by a trained professional. A cracked heat exchanger can leak carbon monoxide into your living space, which is why we check it on every gas furnace visit. If we find one, we show you the problem and give you options, and we won’t leave a dangerous system running.
Furnace Tune Up
Furnace Tune Up is the seasonal service that gets your heating system ready for the cooler months Houston does get. A proper tune up costs $80 to $200 and takes about 90 minutes, and it’s the single best investment you can make if you don’t want a January breakdown. We clean the burner, check gas pressure, test the igniter and flame sensor, and inspect the heat exchanger for cracks.
What We Actually Do During a Tune Up
We don’t just change a filter and call it done. We measure gas pressure with a manometer, check the amp draw on the blower motor, test the temperature rise across the heat exchanger, and verify every safety switch works. You get a written report showing each reading and what it means.
Best Time to Schedule in Houston
October and early November are the sweet spot for Houston furnace tune ups. The system has been dormant through the long summer, and running it for the first time in months is when latent problems show up. Schedule before the first real cold snap, and you won’t be waiting on a repair when the whole city’s heat kicks on at once.
Emergency Furnace Repair
Emergency Furnace Repair is what we do when Houston gets one of its sudden cold snaps and your furnace decides that’s the moment to quit. We keep technicians on call around the clock, and a live person answers the phone at (832) 371-9862 no matter what hour you call. Emergency furnace repairs run the same $150 to $700 range as standard calls, because we don’t believe in charging more because you called at 2 a.m.
What Counts as an Emergency
Cold air blowing when the thermostat calls for heat, a burning smell that doesn’t go away, a furnace that won’t start at all, or a carbon monoxide detector going off all count as emergencies. All of these get priority routing. If you smell gas, leave the house and call your gas utility first, then call us.
Same-Day Response Across Houston
When Houston’s temperature drops fast, we add routing in neighborhoods like Missouri City, Channelview, La Porte, and Alvin to compress drive times. We don’t promise a fixed arrival time in an emergency, but we do promise a live person who tells you what’s actually happening, not a voicemail tree that goes nowhere.

AfterBrands We Service
Carrier: We’ve worked on hundreds of Carrier furnaces across Houston, and we keep their OEM igniters, flame sensors, and control boards stocked on our trucks. The Carrier units from the last 10 years have specific fault-code patterns, and our techs read those codes rather than guessing at the problem. Whether you have a Carrier from 2008 or 2023, the repair will be done with the right parts and backed by our 365-day guarantee.
Trane: Trane furnaces are common in Houston’s better-built homes, and we know their quirks. Trane’s pressure switches and inducer motors fail in predictable ways, and we keep those parts on hand. We also service the Trane heat pumps and dual-fuel systems that many Houston homeowners pair with their furnaces.
Lennox and Goodman: Lennox systems use proprietary control boards that many companies order and wait for, but we stock the common ones. Goodman is the workhorse of Houston, affordable and everywhere, and Goodman’s igniter and circuit board failures are so common we carry replacements for nearly every model year. Whether you have a Lennox from West University Place or a Goodman in La Porte, we can have it running in one visit.
Those are just three examples. Our technicians are trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Whether you have a Trane or any other make, we can help.
Signs You Need a Pro Right Now
- Cold air is blowing from your vents. If the furnace fires but the air feels cold, the burners may be shutting off early or the blower may be running without the burners lit. This often points to a flame sensor or gas valve issue, and it won’t fix itself.
- You smell gas or a strongly acrid burning odor. A brief dusty smell on first startup is normal, but a persistent gas smell means leave the house and call your utility. A burning smell that doesn’t clear in a few minutes means wiring or the blower motor is overheating, and that’s a fire risk.
- The furnace short cycles, turning on and off every few minutes. This is usually a dirty flame sensor, a clogged filter, or an overheating limit switch. Short cycling wastes gas, strains the system, and shortens the life of the heat exchanger.
- The pilot light or ignition is unreliable. If you have to relight a pilot or the furnace only starts sometimes, the thermocouple or electronic igniter is failing. Intermittent ignition is a warning that a no-heat failure is coming soon.
- Your carbon monoxide detector is sounding. Treat this as an emergency every time. Get everyone outside, ventilate if safe, and call your gas utility. Then call us, and we’ll inspect the heat exchanger and venting before the system runs again.

How Much Does Furnace Repair Cost in Houston?
A typical furnace repair in Houston runs $150 to $700 depending on what failed and how complex the replacement is. Igniter replacements are the most common fix and usually run $150 to $280, parts and labor included. Flame sensor cleaning or replacement runs $150 to $225. A blower motor replacement lands between $400 and $650, while control board failures run $250 to $500. A gas valve replacement is $350 to $600. The wide range reflects the difference between a $200 part and a $600 component plus labor.
What affects the cost? The part that failed is the big one, but furnace age matters too. Older systems may need hard-to-find parts, though Houston’s housing stock is young enough that most furnaces we see are under 15 years old. Brand matters less than availability, which is why we stock parts for the nine brands we service. Time of year barely affects our pricing, because we don’t charge overtime or after-hours premiums, ever.
To avoid overpaying, get the price in writing before work starts, which is exactly what we do on every job. A free estimate should include the diagnosis, the specific part needed, the cost of the part and labor, and the guarantee terms. That’s what you’ll get from us, written down, before you agree to anything. Call (832) 371-9862 for an exact quote on your furnace, and the estimate is free.
