We’ve served the Four Corners area for over 42 years.

They call us because we know their houses. We’ve crawled through enough 140°F attics in ZIP 77083 to recognize the telltale signs of flex duct collapse and heat exchanger fatigue before we even pull the panel.

Our Heating & Furnace Services in Four Corners
Furnace Repair
Four Corners furnace repair calls spike every January when the first real cold front pushes through. The most common culprit is a failed ignitor or gas valve on a 1990s-2000s furnace that’s been cooking in a 140°F attic for twenty-plus years. We diagnose the problem, quote the repair upfront, and fix it on the spot when possible. The price quoted is the price paid. Our current offer is $50 off any repair over $250.
Furnace Replacement
This is where Four Corners homeowners face a real decision. Many houses here have post-Harvey mismatched systems: a 2017 condenser paired with a 1999 air handler and original flex duct that was never replaced. The furnace may be limping along, but the whole system is compromised. We give straight talk about repair versus replace. Sometimes a new furnace alone makes sense. Often, the chronic humidity problems and electric bills won’t resolve until the entire split system is properly matched and commissioned. Furnace replacement in Four Corners runs $3,500-$7,500 depending on size, efficiency, and whether ductwork needs addressing.
Furnace Tune-Up
Our $89 seasonal tune-up is the best money you can spend on a Four Corners furnace. We check heat exchanger integrity, gas pressure, blower amp draw, and safety limits. In this zip code, we pay special attention to duct leakage and attic-heat gain, because those 140°F attics destroy system efficiency even when the furnace itself is sound. A tune-up every fall catches problems before the first freeze.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a serious safety issue we see regularly in original Four Corners furnaces. The extreme attic temperature swings accelerate metal fatigue. Carbon monoxide risk is real. We inspect with visual scopes and combustion analyzers. If the heat exchanger is cracked, replacement is often not cost-effective on a 20-plus-year furnace. We’ll tell you honestly. No pressure. Just the facts and a written quote.

Trusted Brands We Service in Four Corners
We’re trained to service all nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Four Corners specifically, we see a lot of original Lennox and Goodman installations from the 1999-2005 building wave, plus post-Harvey Rheem and York replacements where homeowners chose what was available fast. We stock common ignitors, gas valves, blower motors, and control boards for these brands on every truck. That means faster turnaround for Four Corners customers and fewer return trips. If you have a 2001 Lennox furnace and wonder whether parts are still available, the answer is usually yes. When they’re not, we’ll tell you straight and give you a replacement quote with no runaround.
Common Heating & Furnace Problems We See in Four Corners Homes
- Leaking or failed heat exchangers in original 1990s furnaces. The attic temperature extremes in 77083 accelerate thermal cycling stress. We find cracks in units as young as 18 years that would have lasted 25+ in a conditioned closet.
- Blower motor burnouts from mismatched post-Harvey systems. An oversized condenser paired with an original air handler creates excessive static pressure. The blower works harder, draws more amps, and fails prematurely.
- Refrigerant charge issues from uncommissioned split-system swaps. After Harvey, many Four Corners homeowners replaced only the flooded condenser. The system was never properly charged for the new coil-air handler pairing. Poor heating performance and high humidity are the result.
- Collapsed flex duct sections from attic heat aging. Even in homes built in 2005, we’ve found ductwork that’s brittle, torn, and leaking conditioned air directly into the attic. The furnace runs constantly. Rooms stay cold. Bills go up.

The Four Corners HVAC Story Nobody Else Is Telling
Here’s what makes this zip code different from Katy or Sugar Land. Four Corners (ZIP 77083) sits in the southwest Houston suburbs where a massive 1990s-2000s residential building boom created a large cohort of HVAC systems now hitting the 15-25 year replacement window simultaneously. Hurricane Harvey (2017) flooded significant portions of this low-lying Fort Bend County community, prompting widespread outdoor condenser replacements. But many homeowners replaced only the flooded unit, leaving original aging air handlers and flex ductwork in place. That created chronically mismatched split systems that underperform on dehumidification and cause ongoing refrigerant charge issues.
We serviced a 1999 brick-veneer home on Glencliff Drive where the homeowner was on their third condenser since Harvey but still had the original 1999 air handler with a cracked heat exchanger. The flex duct was collapsed in three sections from attic heat aging, and the mismatched 16-SEER condenser with the old evaporator coil caused constant short-cycling and humidity over 70%. We replaced the entire split system and re-ran ductwork, finally giving them a properly commissioned system that holds 50% RH even on sticky August days.
This pattern is the signature service call in 77083. A homeowner has a 2017-era Carrier or Lennox condenser paired with a 2001 air handler and original flex duct that was never replaced. The system was never re-commissioned after the swap. Technicians routinely find incorrect refrigerant charge, mismatched coil efficiency ratings, and collapsed duct sections all contributing to sky-high electric bills and humidity complaints the homeowner blames on the “new” equipment. We know how to read this situation and fix it properly. That’s why Four Corners homeowners who’ve been burned by quick-fix Harvey repairs call us when they’re ready to do it right.

FAQs - Heating & Furnace in Four Corners
In most Four Corners homes with post-Harvey mismatched equipment, replacing the whole system is the wiser investment. A new furnace paired with a 2001 air handler and collapsed flex duct will still short-cycle, struggle with humidity, and cost more to operate than it should. We assess your specific setup and give straight talk. Call (833) 313-7291 for a free evaluation.
Heat exchanger replacement on a 20-plus-year furnace is rarely cost-effective. The part is expensive, the labor is extensive, and other components are likely near failure. We inspect with scopes and combustion analyzers. If replacement is needed, we’ll quote a new furnace with no pressure. Safety comes first.
Short-cycling in Four Corners usually points to a mismatched system or ductwork problem, not the furnace itself. An oversized condenser paired with an original air handler creates excessive static pressure. Collapsed attic ducts restrict airflow. The furnace overheats and shuts down prematurely. A tune-up cleans and adjusts, but it can’t fix a fundamentally mismatched installation. We diagnose the root cause.
Once a year, every fall, before the first Houston cold snap. Four Corners’s 140°F attics and year-round humidity put extra stress on blowers, heat exchangers, and electrical components. Our $89 seasonal tune-up catches problems early and keeps your warranty valid. Call to schedule before the rush.
Usually yes, for common components like ignitors, gas valves, and blower motors. We stock Lennox parts on every truck. For obsolete control boards or discontinued heat exchangers, we’ll tell you honestly and quote replacement options. No runaround. Call (833) 313-7291 with your model number.
