Richmond spans a wider range of equipment ages than anywhere else in Fort Bend County, from systems retrofitted into houses built before ducted air was normal to 2020s installations a few miles away. The useful question here is almost never which brand. It is whether this system is worth another repair.
A median household income of $50,337 and 53.5% owner-occupancy make Richmond a different market from the west-county communities twenty minutes away, and the honest consequence is that a great deal of published air conditioning content simply does not apply. Two-stage equipment, variable-speed blowers and efficiency-tier payback calculations are real things that matter in the right house. They are not the question when the question is whether this summer can be got through.
What actually helps is arithmetic rather than aspiration. Under about eight years, repair almost always wins. Between eight and twelve it depends entirely on what failed: a capacitor or a contactor is worth fixing on almost any system, while a compressor or an evaporator coil rarely is. Past twelve, a repair costing a third of a new system is usually money spent on a machine whose remaining components are all the same age as the one that just failed.
The refrigerant on the data plate is the other decisive fact, and on Richmond’s older stock it is frequently R-22. Production ended in 2020 and servicing depends on reclaimed stock, so a leak or a compressor on an R-22 system is a replacement decision in all but name — while a capacitor on that same system is a $200 repair worth making. EPA is explicit that nobody is required to replace working equipment. See refrigerant and system age.
Richmond adopted the 2024 International Codes — building, residential, plumbing, mechanical, energy, fuel gas and fire — together with the 2023 National Electrical Code. That is the most current cycle of any city in Fort Bend County, ahead of Missouri City’s 2021 family, Stafford’s 2015 codes and Fulshear’s 2015 set.
The practical benefit is specific rather than abstract. The 2024 IMC and IFC are the editions that carry the installation and service provisions for A2L refrigerants — R-454B and R-32, which is what new equipment now uses. Those provisions cover charge limits tied to the conditioned area served and the circumstances requiring a refrigerant detection system. A city working from the 2024 codes has a rulebook that addresses the equipment currently being sold; several of its neighbors are working from editions written before that equipment existed.
Richmond’s building department publishes its adopted editions clearly but does not spell out HVAC permit requirements in text, so confirm what a changeout at your address requires rather than inferring it from the code list.
Richmond has been the county seat since December 1837, and the older housing near the historic core predates the assumption that a house comes with ducted air. Where cooling was retrofitted, the duct system was fitted into a building that had no space allocated for it — runs squeezed through closets and soffits, undersized returns, and equipment placed wherever it fit rather than where it made sense.
That produces a specific pattern: rooms that never keep up, high static pressure the blower has to fight, and a house that responds poorly to simply putting a bigger machine on the same distribution. It is the strongest local argument for measuring the duct system before choosing equipment — a static pressure reading takes minutes and frequently changes the answer. See duct repair and sealing and sizing and load calculations.
It is also why Richmond is a market where ductless mini-splits are worth a look for one persistently bad room, rather than re-engineering the whole distribution to fix it.
Start with AC repair if the system has just stopped, and refrigerant and system age before agreeing to any repair on a system old enough to be on R-22. AC permits in Fort Bend County covers where Richmond sits against the rest of the county.
