Our Heating & Furnace Services in Alvin
Furnace Repair
A furnace that won’t light, cycles too often, or blows cold air into your Alvin living room isn’t something to wait on. Most repairs run $150-$700, and we complete the majority in a single visit. We stock ignitors, flame sensors, and control boards for Carrier, Trane, Lennox, and Goodman systems common in Alvin’s older neighborhoods. If your furnace is original to a 1970s ranch near Alvin Community College, we’ll tell you straight whether repair makes sense or if you’re throwing money at borrowed time.
Furnace Replacement
When repair costs stack up or your furnace has rusted through from repeated flood exposure, replacement is the smarter spend. A new furnace installation in Alvin typically runs $3,500-$7,500, depending on size, efficiency, and whether your ductwork needs attention. We size every system for Alvin’s brutal latent load - 55-60 inches of annual rainfall means your furnace and air handler must manage moisture, not just temperature. For homes in flood-prone areas like those near Mustang Bayou, we recommend sealed-combustion units on elevated risers. The price quoted is the price paid, backed by our 90-Day Done Right Promise.
Furnace Tune-Up
Our $89 seasonal tune-up catches the problems Alvin’s climate creates before they strand you without heat. We inspect heat exchangers for rust, test gas valves for corrosion, and verify combustion air supply in slab-on-grade homes where original closets were never designed for modern equipment. Annual service extends equipment life and keeps your warranty valid. Most Alvin homeowners schedule in October, before the first cold front rolls through Brazoria County.
Heat Exchanger Inspection & Replacement
This is where Alvin’s unique conditions hit hardest. Heat exchangers in flood-prone homes corrode from the inside out when moisture seeps into crawlspaces and furnace closets. A cracked heat exchanger can leak carbon monoxide into your home. We inspect with cameras and combustion analyzers; replacement runs $150-$700 for the part, with full replacement sometimes the safer path. In Oak Shadows, we replaced the original 1978 Rheem furnace in a slab-on-grade ranch where the heat exchanger had rusted through after Harvey floodwaters seeped into the crawlspace. We installed a sealed-combustion Lennox furnace on a 16-inch composite riser - a standard for flood-prone Alvin - and ran new gas line to prevent future moisture intrusion.
Gas Valve Repair
Gas valves in Alvin’s unconditioned attics and crawlspaces fail prematurely from sustained humidity. If your pilot won’t stay lit or gas flow is erratic, the valve may be corroded internally. We replace with new valves rated for high-moisture environments and can relocate controls to conditioned spaces where practical. Safety first: gas work is not a weekend project. Our journeyman technicians are licensed and trained to handle it properly.
Ignitor Replacement
Hot surface ignitors crack and fail after years of thermal cycling, especially in Alvin homes where furnaces work hard through humid shoulder seasons. We carry universal and OEM ignitors for most brands and can swap one in under an hour. If your furnace clicks but never flames, this is likely the culprit.

Trusted Brands We Service in Alvin
We’re trained to service and repair Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

Common Heating & Furnace Problems We See in Alvin Homes
- Heat exchanger cracks from flood exposure. Alvin holds the U.S. 24-hour rainfall record - 43 inches from Tropical Storm Claudette in 1979 - and its low-lying topography means furnace heat exchangers and gas valves routinely corrode from flood moisture, a problem far less common in drier Houston suburbs. Post-Harvey, we’ve replaced dozens of units in homes near Mustang Bayou and along Highway 35 where water reached furnace closets.
- Gas valve corrosion in unconditioned attics. The 1960s-1980s ranch homes that dominate Alvin’s housing stock often have furnaces in attic spaces that see 95-degree heat and 80-percent humidity ten months a year. Gas valves rust internally, causing intermittent ignition or complete failure. We see this constantly in neighborhoods near Alvin Community College.
- Undersized ductwork creating pressure problems. Original attic ductwork in Alvin’s older homes was sized for the cooling loads of the 1970s, not the latent demands of today’s climate. When we replace furnaces in these homes, we often find ducts that whistle, leak, and can’t move enough air for a properly sized modern unit. Sometimes the ductwork needs replacement alongside the furnace.
- Improper combustion air in slab-on-grade closets. Original furnace closets in Alvin’s ranch homes were designed for natural-draft equipment with louvered doors. Modern sealed-combustion furnaces need dedicated outdoor air intake, and many closets lack the space or the penetration. We solve this with sidewall venting or closet modification, done to code.

FAQs - Heating & Furnace in Alvin
Yes - in Alvin, “never flooded” is not the same as “won’t flood.” The city holds the national rainfall record, and Harvey proved that water reaches places no one expected. Elevating a condensing unit or sealed-combustion furnace on a 12-18 inch riser costs a few hundred dollars during replacement and can save the entire system in the next major event. We recommend it for any home below the 50-foot contour, which covers most of Alvin. Call (833) 313-7291 and we’ll assess your specific lot and flood history.
Your gas valve is corroding from sustained humidity in an unconditioned attic or crawlspace, which is standard construction in Alvin’s 1960s-1980s ranch homes. The moisture attacks internal components, causing intermittent operation or complete failure. We replace with corrosion-resistant valves and can often relocate controls to conditioned space or improve ventilation. If you’ve replaced the same valve twice, the environment is the problem - not the part. We can fix that.
A 1979 heat exchanger cannot be repaired safely - replacement of the entire furnace is the only responsible option. Heat exchangers that old are thin-wall steel, often already cracked from decades of thermal cycling and possibly corroded from flood moisture. No reputable technician will patch or weld one. A new sealed-combustion furnace eliminates the safety risk, cuts gas bills, and qualifies for our 90-Day Done Right Promise. We’ll give you a straight repair-versus-replace number so you can decide.
Carrier and Lennox both manufacture sealed-combustion furnaces with excellent moisture resistance, and we install both regularly in Alvin. The brand matters less than the installation details: elevated riser, proper sidewall venting, and combustion air drawn from outside rather than the humid closet. We’ve had excellent results with Lennox SL280V and Carrier Infinity 98 installations in post-Harvey rebuilds. The right unit for your home depends on size, ductwork, and budget - we’ll walk through it without pressure.
The musty smell is mold or mildew in your ductwork, plenum, or evaporator coil - all common in Alvin’s high-humidity environment. Cleaning the furnace cabinet helps, but if the ducts themselves have absorbed decades of moisture (typical in original 1970s attic systems), the smell returns. We inspect with cameras and can treat or replace ductwork as needed. Sometimes the real fix is improving dehumidification so the problem doesn’t recur. Call (833) 313-7291 for a full diagnostic - estimates are free.
