Fast, Reliable Heating & Furnace Across Houston
Heating and furnace repair in Houston typically costs $150-$700, with most jobs completed in a single visit and a live person answering calls at (833) 313-7291 around the clock. We’re the Heating & Furnace team at Fireside Heating & Air Co., and we’ve been serving Houston homeowners since 2018 - over 42 years of showing up when we say we will, quoting the price you’ll actually pay, and standing behind our work with a written 90-Day Done Right Promise.
Houston’s furnace problems aren’t like Dallas’s or San Antonio’s. Our combination of extreme Gulf humidity and attic temperatures that climb past 130°F in summer creates thermal stress on heat exchangers that cracks them faster than nearly anywhere else in the country. When a January cold snap drops outdoor temperatures into the 30s while your attic still holds desert-level heat, that rapid expansion and contraction does real damage. We know the Meyerland ranch homes with original 1990s ductwork, the Memorial brick-veneer houses with furnaces baking in unconditioned attics, and the southwest Houston neighborhoods where clay soil shifts have pulled apart flex-duct connections. That local knowledge means we diagnose faster, repair right the first time, and don’t waste your afternoon chasing symptoms instead of causes.
Our technicians are journeyman-trained, background-checked, and uniformed - shoe covers on without being asked. The price we quote is the price you pay. Call (833) 313-7291 any hour; a live person picks up, every time.
Why Fireside Heating & Air Co. of Houston Is Houston’s Preferred Heating & Furnace Company
We’ve built our reputation in Houston one repair at a time, across four decades and three generations of local families. Homeowners in Bellaire, West University Place, and throughout Harris County call us back because we treat their homes the way we would our own mother’s - no shortcuts, no phantom charges, no paperwork battles if something isn’t perfect.
Our 90-Day Done Right Promise is written and binding: if it’s not done right, we make it right, period. No forms to fill out, no phone trees, no arguing. That promise, what we call the Keystone Standard, has kept our phones ringing since 2018. And those phones are answered by a live person, 24 hours a day, 7 days a week, including the 2 a.m. calls when your furnace quits on the coldest night of the year.
Most of our Houston jobs finish in a single visit. We stock parts for Carrier, Trane, Lennox, and Goodman systems - the brands we see most often in Houston’s 1970s-1990s housing stock - so you’re not waiting days for a warehouse shipment while your house sits cold. We’re trained on all nine major residential brands, but we keep the common ones on our trucks because Houston’s slab-on-grade ranches and brick-veneer homes deserve faster service than a parts chase.
Our Heating & Furnace Services in Houston
Furnace Repair
A typical furnace repair in Houston runs $150-$700, depending on the part and the access. We see a lot of ignitor failures in Houston’s poorly sealed furnace cabinets, where rapid expansion and contraction from attic temperature swings snap the ceramic element. Gas valve malfunctions are common too - Gulf humidity corrodes electrical contacts that drier climates simply don’t stress. We’ll tell you straight whether repair makes sense or if you’re throwing money at a unit that’s already told you it’s finished.
Heat Exchanger Replacement
Heat exchanger work in Houston falls in that same $150-$700 range for repair scenarios, though full replacement can run higher depending on furnace age and accessibility. This is where Houston’s climate exacts its toll. Last January, we replaced a cracked heat exchanger in a Carrier furnace for a home in Meyerland. The 20-year-old unit had been cycling rapidly during a cold snap, and the thermal shock from the 140°F attic to 50°F outdoor air caused a hairline crack that emitted carbon monoxide into the living space. We caught it during a routine inspection, but it could have been much worse. If your carbon monoxide detector has chirped or your furnace cycles on and off every few minutes, call us. This is not a wait-and-see situation.
Gas Valve Repair
Gas valves fail in Houston for reasons that don’t apply in Phoenix or Denver. The relentless humidity works its way into electrical connections, causing intermittent firing or complete shutdown. We clean, test, and replace valves with OEM-spec parts, and we check the entire gas train while we’re there - because a valve symptom often masks a pressure regulator issue or a pilot assembly that’s been corroding quietly for two seasons.
Furnace Tune-Up
Our $89 Seasonal Tune-Up is the best money you’ll spend on prevention. In Houston, we don’t just check filters and belts. We treat condensate drains for algae and biofilm - a standard line item here, not an upsell, because year-round heat and near-constant humidity turn neglected drain pans into problems within a single season. We inspect heat exchangers with cameras, test gas pressure, and check for the hairline cracks that Houston’s thermal stress produces. A tune-up takes about an hour. A midnight emergency call on a 38-degree night takes longer and costs more.

Trusted Brands We Service in Houston
We’re trained to service nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Houston’s older neighborhoods - Meyerland, Memorial, the southwest Houston tracts built during the oil boom cycles - we see Carrier and Trane systems most often, with Goodman and Lennox close behind. We stock common ignitors, gas valves, blower motors, and heat exchanger assemblies for these brands on our trucks, which means same-day repair for most Houston homeowners instead of a multi-day parts hunt. If your furnace is one of the less common brands in our training set, we source parts through our Houston distributors with next-morning availability on most items. Every repair uses OEM-spec or manufacturer-approved components - no generic substitutions that void your warranty or fail in six months.
Common Heating & Furnace Problems We See in Houston Homes
- Heat exchanger cracking from attic thermal stress. Houston’s furnaces sit in 130-150°F attics for eight months, then get asked to fire to 150°F internal temperatures when a January cold snap hits. That rapid thermal cycling cracks exchangers faster than in any climate with milder summers or basements to house the equipment.
- Gas valve corrosion from Gulf humidity. Electrical contacts in gas valves oxidize in Houston’s moisture-laden air, causing delayed ignition, intermittent firing, or complete failure. We test valve coils and solenoid resistance on every service call because we’ve learned to expect what other markets rarely see.
- Ignitor failure from expansion-contraction fatigue. Hot attic air seeps into poorly sealed furnace cabinets during Houston’s nine-month summer, then cold snaps cause rapid contraction. Ceramic hot-surface ignitors don’t tolerate that repeated stress well.
- Rapid cycling from oversized or degraded systems. Many Houston homes still run original 1990s furnaces paired with ductwork that’s been baking on superheated attic floors for decades. Short cycling from restricted airflow or failed limit switches is the symptom; the cause is usually a system that’s been fighting Houston’s unique conditions without proper maintenance.

FAQs - Heating & Furnace in Houston
Houston’s furnaces endure thermal stress that most climates simply don’t produce. Your furnace sits in a 130-150°F attic for most of the year, then must heat rapidly when outdoor temperatures drop into the 30s or 40s during brief winter cold snaps. That extreme temperature swing causes metal expansion and contraction that fatigues the heat exchanger welds and seams. In climates with basements or milder summers, furnaces don’t experience this thermal shock, and heat exchangers last years longer. If your furnace is 15-plus years old and in a Houston attic, annual inspection with a camera is not optional - it’s essential. Call (833) 313-7291 to schedule; estimates are free.
Yes, and in Houston it’s arguably more important than in colder climates. Your furnace may only run a few dozen nights per year, but those are precisely the nights when thermal stress is most extreme - cold outdoor air, hot attic, rapid cycling. Meanwhile, humidity never takes a season off. Condensate drains clog with algae, electrical contacts corrode, and heat exchangers develop hairline cracks that carbon monoxide can slip through. Our $89 tune-up catches these issues before they become dangerous. The $89 spent in October beats the emergency call at 2 a.m. in January. Call (833) 313-7291 to book.
Often yes, if both systems are aging. Houston’s attic conditions punish air handlers and furnaces equally, and matched systems from the same era usually fail within a few years of each other. Replacing both together lets us properly size the system for Houston’s latent heat load - the dehumidification demand that oversized or mismatched equipment can’t meet. A correctly sized, properly installed system in Houston will outlast a mismatched pair by years. That said, if your furnace is solid and your AC is the problem, we won’t sell you what you don’t need. Straight talk about repair versus replace is what we do. Call (833) 313-7291 for an honest assessment.
Ignitor replacement and gas valve cleaning or replacement are the calls we run most often in Houston. The ignitor fails because ceramic elements don’t tolerate repeated expansion and contraction from attic temperature swings. The gas valve fails because Gulf humidity corrodes electrical contacts that stay dry in arid climates. Both are usually same-day repairs with parts we stock. A typical ignitor or gas valve repair in Houston runs $150-$400, well within our overall repair range. If you’re getting no heat, a clicking sound without ignition, or intermittent firing, it’s likely one of these two. Call (833) 313-7291 - we can usually be there today.
Houston does not have a city-mandated furnace inspection specifically for residential real estate transactions, though some buyers’ inspectors will flag obvious safety issues like visible rust, improper venting, or missing disconnects. Harris County and incorporated suburbs may have varying requirements, and mortgage lenders sometimes require a general HVAC assessment. If you’re selling a home in Meyerland, Memorial, or Bellaire and want to avoid last-minute negotiation surprises, a pre-listing inspection from Fireside gives you documentation of condition and any needed repairs. We charge for the inspection but apply that fee toward any work you choose to have us complete. Call (833) 313-7291 to schedule.
