A 1990s–2000s lake community at the replacement crossroads
Grand Lakes built out from the late 1990s through the 2000s: two-story brick homes, most 2,500–4,000 square feet, arranged around stocked lakes and greenbelt trails with Katy ISD schools. It's a textbook example of the era's construction — one system zoned across two floors, media rooms over garages, and builder-grade equipment.
Homes that haven't replaced their original systems are running against the R-22 phase-out: since production ended January 1, 2020, a major failure on an R-22 unit usually means replacement rather than repair. Homes on their second system face a different question — whether the 1990s ducts and zone hardware under it are the real comfort bottleneck.
R-22 economics
Recharging with reclaimed R-22 is legal but scarce and expensive. For a leaking or failed R-22 system we show the honest math on repair versus a modern replacement and let you decide.
Zone dampers and hot game rooms
The room over the garage is the classic Grand Lakes hot spot — long duct runs, west sun, and aging dampers. A zoning diagnostic separates the cheap fix from the equipment conversation.
Panel capacity for modern loads
EV chargers and pool equipment strain 1990s panels. We evaluate capacity, upgrade where needed, and pull the correct Fort Bend County permit.
Rebates & permits in Grand Lakes
Grand Lakes is CenterPoint Energy territory in the retail-choice market. CenterPoint incentives start at $200 for qualifying 15.2+ SEER2 replacements — a natural pairing with a forced R-22 retirement — applied to your invoice through a participating contractor, plus the free ComfortCheck A/C tune-up for qualifying systems (verified July 2026 at centerpointenergy.com).
The community sits in unincorporated Fort Bend County (MUD-served), so mechanical and electrical permits run through the county rather than a city office — we verify the jurisdiction and pull the right permit on every job. The federal 25C energy-efficiency tax credit ended for equipment placed in service after December 31, 2025, so utility programs are the main source of HVAC savings in 2026 (verified July 2026 against the IRS OBBB FAQ).

Grand Lakes questions we hear the most
My Grand Lakes AC uses R-22 — is repair still worth it?
Rarely, for major failures. Reclaimed R-22 is legal but scarce and expensive since production ended in 2020. We quote the repair and the replacement side by side so the decision is yours, with real numbers.
Why is the room over my garage always hot?
Long duct runs, west-facing sun, and aging zone dampers — the classic combination in this era of Katy construction. A zoning and airflow diagnostic finds which one is failing before anyone talks new equipment.
Who permits HVAC work in Grand Lakes?
Fort Bend County — the community is unincorporated and MUD-served. Avatex verifies jurisdiction and pulls the correct county permit as part of every change-out.
Is there a rebate for replacing my system in Grand Lakes?
Yes — CenterPoint incentives start at $200 for qualifying 15.2+ SEER2 central AC, heat pump, and mini-split systems, applied to your invoice through a participating contractor (verified July 2026).
