Searching for AC repair in Fulshear, TX, usually means something has gone wrong with a fairly young system in a fairly young house. That changes the order of the steps: on a new home, the right first call may be to your builder, not to a repair company. This page walks through that order, and through how the free line can connect you with a local contractor when you do need one.
Houston Air & Heating is a call line. It owns no tools and sends no crews. Call (832) 662-4107 and an automated assistant asks whether the trouble is heating or cooling and what the equipment is doing, then passes your call to a locally owned contractor, independent of the line, that takes Fulshear jobs. The contractor diagnoses the problem, quotes and does the work.
Fulshear: a small Fort Bend town surrounded by new neighborhoods
Fulshear sits in western Fort Bend County, on the far west side of the Houston area. The 2020 Census counted 16,856 residents, up from 1,134 in 2010, and the Census Bureau's July 2025 estimate is 64,630. Between 2024 and 2025 it ranked second among the fastest growing U.S. cities of 20,000 people or more. Large master planned communities have grown up around the old town center, and a big share of the homes here were built recently. For heating and cooling, that has a practical upshot: many systems are still inside their warranty periods, many have never had a full season of maintenance, and many owners have never needed a repair before.
New does not mean trouble free. A system installed during construction was set up in a house with no furniture, no family and often no summer yet. The first real August is when hidden installation problems tend to show up.
From plantation stop to boomtown
The town's name comes from Churchill Fulshear, one of Stephen F. Austin's Old Three Hundred colonists, who settled on land granted by Mexico in 1824. His son gave a railroad a right of way through the family land in 1888, and the town site was laid out in 1890. For most of the twentieth century Fulshear stayed a small farm town of a few hundred people or fewer, until Houston's growth reached it beginning in the 1970s. The city incorporated in 1977 and is now a home rule city.
That history explains the housing mix. A handful of older homes sit near the original town center, but with the population growing from about a thousand people in 2010 to tens of thousands today, most Fulshear houses are recent builds on former ranch and farm land. If your home is one of them, its heating and cooling system is probably the first one the house has ever had.

Three warranties to check before you pay for a repair
The exact terms are in your closing papers and equipment booklets. These are the questions to answer first.
The builder warranty
Covers workmanship for a set time after closing. A duct that came loose, a drain line with no slope or a refrigerant joint that leaks from day one may fall here. Report it the way the warranty asks, usually in writing.
The equipment warranty
Covers parts from the manufacturer. Some makers offer a longer term only if the unit was registered online within a short window after installation. Find the model and serial numbers and check the maker's website.
The labor coverage
A parts warranty rarely pays for the hours to install the part. Find out whether the original installer covers labor, and for how long, before you agree to a bill.
Problems that show up in a new home's first summers
- A drain line that backs up. If the condensate line was not sloped or trapped well, water collects and a safety float switch shuts the system off. Look for water in the pan under the indoor unit.
- A warm upstairs. Dampers that were never adjusted after move-in, or ducts that were pinched during construction, can starve upstairs rooms of air.
- A filter clogged fast. Fine construction dust keeps settling for months. Check the filter monthly the first year and change it when it looks gray.
- A system that never shuts off. On the hottest afternoons long run times can be normal. A change from last summer, or rooms that will not get below the high 70s, is worth a service call.
- A room that has never cooled. If it has been warm since the day you moved in, it is likely a design or installation issue, which points back to the builder warranty.
Safe checks before you call
Set the thermostat to Cool and a few degrees below the room temperature, and replace its batteries if the screen is blank. Pull the filter and swap it if it is dirty. If the outdoor unit is silent, check for a tripped breaker and reset it a single time; if it trips again, leave it alone. Clear away grass clippings, toys or bags that have blown against the outdoor unit. Anything involving refrigerant, wiring or the gas furnace is for a technician.
A gas odor indoors means everyone walks out first; phone 911 and the gas utility only once you are clear of the house. CenterPoint Energy lists 888-876-5786 for reporting a gas leak in the Houston area; if Si Energy serves your street, use the emergency number on its bill. The same goes for a sounding carbon monoxide detector: out of the house, then 911.
Permits when a system is replaced
The City of Fulshear's rule is broad: anyone who plans to replace an electrical, gas, mechanical or plumbing system within the city limits or the ETJ must apply to the Building Official and get a permit first. The exemptions are narrow, such as portable heaters, portable cooling units and a minor part that does not change how the equipment was approved. A full change out of an air conditioner or furnace is not on that list. The city takes trade permit applications, including HVAC, through its online portal, and its inspectors work weekdays. Before you sign, find out which side applies for the permit and whether the final inspection is included in the price.
Planning ahead for the first replacement
Builders usually choose equipment that meets the code minimum for efficiency. That is perfectly workable. When the first replacement comes due years from now, it is a chance to ask about two stage or variable speed equipment, which can run longer at low speed and pull more moisture out of the air in Fort Bend's sticky summers. Keep a folder with the model numbers, install date and every service invoice, because the next contractor will ask.

About this line: Houston Air & Heating is a free phone line, not an HVAC contractor. It answers your call and connects you with an independent local heating and air conditioning company, which inspects, quotes and does the work, and which you pay directly. Companies may pay a referral fee. You never pay the line. Read how the line works.
Verify the license before work begins. Texas requires anyone contracting to do air conditioning, refrigeration or heating work to hold an Air Conditioning and Refrigeration (ACR) Contractor license from the Texas Department of Licensing and Regulation (TDLR). Ask the company for its ACR license number, then confirm it on the TDLR license search (opens in a new tab). The line does not check this for you.
