We’ve been driving out to Greatwood since the neighborhood was still building out its final sections in the early 2000s. Our technicians know the two-story brick homes along Greatwood Parkway, the attic furnaces baking in unconditioned spaces above Settlers Grove, and the way Fort Bend County’s black clay soil shifts ductwork year after year. When your furnace quits on a January night and the temperature’s dropping toward freezing, you don’t want a dispatcher reading from a map. You want someone who knows that 77469 covers everything from the original Greatwood sections to the newer villages near the golf course, and who can get a truck to your driveway fast.

Our Heating & Furnace Services in Greatwood
Furnace Repair
Furnace repair in Greatwood runs $150-$700 depending on the part and the accessibility. The most common calls we get from Greatwood homes are failed ignitors, cracked heat exchangers, and gas valve malfunctions. Because so many Greatwood furnaces were installed in the same 1995-2005 window, we’re seeing concentrated failures right now. The builder-grade heat exchangers in those original systems weren’t built to withstand fifteen years of 140°F attic summers, and they crack sooner than they should. A cracked heat exchanger is a carbon monoxide risk. We’ll show you the crack with our camera, explain your options, and never pressure you toward replacement if repair is the honest call.
Furnace Replacement
A full furnace replacement in Greatwood costs $3,500-$7,500. This is where our local knowledge pays off most. Greatwood’s master-planned development concentrated home construction in two main phases, late 1980s through early 2000s, creating a unique situation where entire neighborhoods now face simultaneous HVAC replacement. The bulk of Greatwood’s housing stock is hitting the 20-30 year replacement window all at once. Many homeowners replaced only their flooded outdoor condensing unit after Hurricane Harvey in 2017, leaving a mismatched system: a newer high-efficiency condenser paired with a 1990s-era attic air handler and original ductwork. That combination underperforms and fails prematurely. We recently serviced a 1995 home in the Settlers Grove section of Greatwood where the R-22 coil had pinhole leaks. The homeowner had replaced only the outdoor unit after Hurricane Harvey, leaving a mismatched 2018 condenser paired with the original attic air handler. We recommended a full system upgrade to a Carrier 16 SEER heat pump with matching coil to resolve the chronic undercooling and high humidity. When we quote replacement in Greatwood, we’re looking at the whole system, not just the box that failed.
Furnace Tune-Up
Our $89 Seasonal Tune-Up is the best money you can spend on a Greatwood furnace. Given that your furnace lives in an attic that exceeds 130°F for months each summer, preventive maintenance isn’t optional if you want reliable winter heat. We check gas pressure, flame sensor operation, heat exchanger integrity, and the condition of your flexible duct connections. Fort Bend County’s expansive black clay soils cause year-round foundation movement that gaps and separates duct connections in attics, silently hemorrhaging conditioned air. A tune-up catches this before you’re heating your attic instead of your bedroom. Senior and veteran homeowners receive 5% off, always.
Heat Exchanger Inspection & Replacement
Heat exchanger failure is the most serious problem we encounter in Greatwood furnaces. The extreme attic temperatures in this community’s two-story homes accelerate metal fatigue. When a heat exchanger cracks, combustion gases including carbon monoxide can enter your living space. We inspect with visual scopes and combustion analyzers. If we find a crack, we red-tag the furnace and shut it down. Replacement heat exchangers are available for some models, but given the age of most Greatwood systems, full furnace replacement is often the more reliable path. We’ll give you straight talk about repair versus replace, with real numbers.

Trusted Brands We Service in Greatwood
We service and stock parts for Carrier, Trane, Lennox, and Goodman systems most commonly found in Greatwood homes. Carrier and Trane were popular builder selections in the original Greatwood construction phases, while Goodman systems appear frequently in post-Harvey replacements. We carry ignitors, gas valves, blower motors, and control boards for these brands on our trucks, which means faster turnaround for Greatwood customers. If your system is a different brand from our full list, we can still service it. We just may need to source one part instead of having it in hand.
Common Heating & Furnace Problems We See in Greatwood Homes
- Cracked heat exchangers from extreme attic heat. Greatwood’s unconditioned attics regularly exceed 140°F in summer, and the original builder-grade furnaces installed throughout the community weren’t specified for that thermal load. We find cracks in 20-30 year old heat exchangers more frequently here than in communities with different housing stock or attic designs.
- Illegal R-22 recharges on aging systems. The original R-22 refrigerant systems in Greatwood’s 1990s-era homes can no longer be legally recharged with new refrigerant. When the coil leaks or compressor fails, full system replacement is the only real option. Homeowners who’ve been “topped off” by unscrupulous operators in recent years are often shocked to learn this.
- Mismatched systems from post-Harvey partial replacements. After 2017, many Greatwood homeowners replaced only the flooded outdoor condensing unit. Now they’re living with a newer high-efficiency condenser paired with a 25-year-old coil and air handler. The system runs constantly, humidity stays high, and utility bills climb. The fix is a properly matched full system.
- Duct separation from foundation movement. Fort Bend County’s black clay soils expand and contract with moisture, shifting foundations and misaligning duct connections in attics. Your furnace works harder, rooms heat unevenly, and the system short cycles. We find this during tune-ups and can reseal connections before you’re facing component failure.
Pricing for Heating & Furnace in Greatwood, TX
Here’s what heating & furnace service costs in Greatwood:
| Service | Price Range |
|---|---|
| Furnace Repair | $150-$700 |
| Furnace Replacement | $3,500-$7,500 |
| Furnace Tune-Up | $80-$200 |
What moves the needle within these ranges? Accessibility matters. A furnace buried in a Greatwood attic under blown insulation costs more to reach than one on a platform with a walkable deck. The part itself matters. A standard ignitor runs less than a variable-speed blower motor or a cracked heat exchanger. And the system’s condition matters. A furnace that hasn’t been tuned in a decade often has multiple issues that cascade.
We quote every job upfront before we start work. The price we give is the price you pay. No add-ons, no “while we’re in here” surprises.

FAQs - Heating & Furnace in Greatwood
Greatwood’s large two-story brick homes route all ductwork through unconditioned attics that regularly exceed 130-140°F in summer, and the original builder-grade heat exchangers weren’t built for that sustained thermal stress. The concentrated construction phases from the late 1980s through early 2000s also mean most systems are failing simultaneously now, rather than spread across decades. If your furnace is original to a 1995-2005 Greatwood home, it’s living on borrowed time. Call (833) 313-7291 for a free inspection and honest assessment of remaining life.
No. New R-22 refrigerant has been illegal to manufacture or import in the United States since January 2020, and remaining supplies are prohibitively expensive and unreliable. If your Greatwood home still has an R-22 system and the coil leaks or compressor fails, full system replacement is your only practical option. We’ve encountered homeowners who paid for “recharges” from operators using questionable reclaimed refrigerant. That money is gone, and the leak remains. Call us for a free second opinion on any estimate you’ve received.
This usually indicates a limit switch trip, which shuts down the burners while allowing the blower to continue running for safety. In Greatwood homes, the most common causes are restricted airflow from separated ductwork, a dirty filter, or an overheating heat exchanger. Fort Bend County’s foundation movement gaps duct connections, reducing airflow and causing the furnace to overheat. Don’t reset the system repeatedly. A tripping limit switch is a warning sign, not a nuisance to override. Call (833) 313-7291 and we’ll diagnose it properly.
Yes, and arguably more necessary here than in many markets. Your furnace sits in an attic that exceeds 130°F for months, then fires up in winter with no transition period. The heat exchanger expands and contracts through that extreme cycle. Meanwhile, foundation movement slowly separates duct connections. An annual tune-up catches heat exchanger cracks before they become carbon monoxide risks, verifies gas pressure for safe combustion, and identifies airflow restrictions from shifted ductwork. Our $89 Seasonal Tune-Up takes about an hour and includes a written report. Senior and veteran homeowners save %.
Technically it might run, but we don’t recommend it and we won’t warranty the result. In Greatwood, we repeatedly see the consequences of partial replacements: a post-Harvey outdoor condenser mismatched with a 1990s air handler, or now a new furnace paired with an aging coil. The efficiency ratings don’t match, the refrigerant types may be incompatible, and the system works harder while delivering less comfort. We quote matched systems because that’s what works. If another company is proposing a furnace-only replacement, get our free second opinion before you commit.
