Ten months of cooling a year in Brownsville
Your air conditioner runs from February through November here. That leaves it two months to rest, and the rest of the year it works against afternoons averaging 94°F. A unit sized or installed wrong will run long hours trying to keep up, and long hours wear parts faster.
Any new central air conditioner installed today has to meet 14.3 SEER2, the federal minimum since 2023. Cameron County has also seen 95 damaging wind events and 27 hail events over the past ten years, with hail as large as 3.01 inches. The outdoor unit sits exposed to all of it, so how it's installed and protected matters as much as the equipment itself.

Texas requires HVAC contractors to hold a state license.
Texas licenses HVAC contractors through the Texas Department of Licensing and Regulation. The license is issued to the contractor, not to the job, so it covers the business across every install they do rather than getting reissued each time.
For an AC installation, that license is what stands behind the work. Most cities and counties in Texas also require a permit from the local building office, with an inspection once the unit is in.

- What size air conditioner does my house need?
- There's no single number that works for every house. The right size depends on your square footage, how many windows you have and which way they face, how much insulation is in your attic and walls, and your ceiling height. A contractor will need to walk through your home and run a load calculation to get an answer that fits your house. Guessing at size, or matching what the old unit was, often leads to a system that either can't keep up on a 94 degree afternoon or cycles on and off too fast to control humidity.
- Should I replace the whole system or just the outdoor unit?
- If the indoor coil and outdoor unit are different ages or from different manufacturers, replacing just the outside unit usually isn't a good option. The two are matched to work together, and pairing a new condenser with an old coil can mean the system never reaches the efficiency it's rated for, and sometimes voids the warranty on the new part. A contractor can check the age and condition of your indoor coil and tell you whether it can be matched with new equipment or whether the whole system needs to come out together. With cooling running here from February through November, mismatched equipment has a lot of months to show its problems.
- Do HVAC contractors in Brownsville need a state license to work on my home?
- Yes. Texas requires HVAC contractors to hold a state license, issued by the Texas Department of Licensing and Regulation. Before hiring anyone, ask for their license number and confirm it's current. Licensing means the contractor has met the state's requirements for training and knowledge of the electrical and refrigerant work involved in installing or repairing your system.
