Nearly every house in Fulshear was finished in the last eighteen years, which means almost no system here fails because the building is old. They fail because the equipment was chosen by a builder at the base tier, installed to a schedule, and has now run seven to fifteen Fort Bend summers without anybody thinking about it once.
Worth settling before anything else, because both numbers get quoted. The Census Bureau’s July 2025 estimate for Fulshear is 64,630, against a 2020 census count of 16,856 and roughly 700 residents in 2008. In the Census Vintage 2024 estimates Fulshear was the second-fastest-growing city in America at +26.9%, and it held second place in the Vintage 2025 release at +21%.
Fulshear’s own city manager has publicly put the population within city limits at 42,000 to 46,000. Both figures can be true of different things, and the gap is the sort that arises when a fast-growing city’s estimate is built from building permits while the city counts what it has actually connected. This page uses the Census figure of 64,630 where a number is needed, and flags the discrepancy rather than hiding it.
For air conditioning purposes the more useful number is neither: it is that essentially the entire housing stock is under eighteen years old, which is what makes this an unusual market.
The instinct is that a young city has young equipment and few problems. The first half is true and the second does not follow, for three reasons that are specific to production housing.
The equipment was a line item. It was specified by the builder, at the base tier unless somebody paid to upgrade during the option walk, and specified once for hundreds of houses. Single-stage cooling, a fixed-speed blower, minimum-standard duct and return design, one basic thermostat. See builder-grade systems and first replacement.
Everything is the same age. On a house that has never been re-equipped, the condenser, coil, air handler, drain pan, secondary line and ductwork all date from one install week. They reach the end together rather than in a convenient sequence, which is why a capacitor failure on a twelve-year-old Fulshear system is a different event from the same failure on a five-year-old one.
The whole neighborhood is on the same clock. Where a section went up inside a two-year window, its equipment did too — which is why a street can go from “nobody has had a problem” to several changeouts in a summer, and why contractor availability tightens locally at exactly the wrong moment.
Median household income here is $187,035 and owner-occupancy 90.0% (ACS 2020–2024), and the housing that goes with those numbers is large — frequently two stories, frequently 3,000 square feet or more, and frequently served by one system and one thermostat mounted downstairs.
That produces the single most common comfort complaint in the newer half of Fort Bend County: the upstairs runs four or five degrees warmer than the downstairs and always has. Heat rises, the upstairs ceiling sits under an attic well above 120°F on an August afternoon, and the thermostat is measuring the comfortable floor. The household compensates by setting the downstairs colder, which overcools the ground floor and never equalizes the two.
It is not a fault and it is usually not an equipment failure. It is duct balance, return-air paths, and in some cases zoning — three answers at three very different prices, in that order. Thermostats and zoning sets out which is which, and why zoning pairs badly with the single-stage equipment most of these houses have.
Fulshear became a home-rule city with a charter adopted in 2016 and issues a Trade Permit covering HVAC work through its online portal, under the 2015 International Codes and the 2014 NEC. Inside city limits, a changeout is permitted work.
Outside them, it is not. Fulshear’s extraterritorial jurisdiction is large, and under Town of Lakewood Village v. Bizios (Tex. 2016) and Collin County v. City of McKinney (Tex. App.—Dallas 2018), no Texas city — home rule included — can enforce building codes or require building permits in its ETJ. Jordan Ranch sits in Fulshear’s ETJ, confirmed on its own recorded plat, so no city mechanical code applies there. Cross Creek West is outside city limits too, with no City of Fulshear line on its tax breakdown.
Cross Creek Ranch itself is served by the city’s water system and the city’s trash contract, which points toward city limits, but that could not be confirmed against an official boundary map — and the distinction between Cross Creek Ranch and Cross Creek West is exactly the sort of thing that gets conflated. Check your parcel rather than your community name. A Fulshear mailing address is not a statement about jurisdiction. What that changes.
For a house of this age the two pages that matter are builder-grade systems and first replacement — particularly the warranty registration and transfer section — and thermostats and zoning for the upstairs problem. If the property is in the ETJ rather than the city, read AC permits in Fort Bend County.
