Nine months of cooling in Corpus Christi
Your air conditioner runs from March through November here, nine months of the year. On a 94°F afternoon it is not cycling on and off, it is running long stretches just to hold the house steady. That kind of runtime is what wears out a compressor before its time.
A new system installed here has to hold up to that load, and it has to meet the federal minimum of 14.3 SEER2 if it is a central air conditioner built since 2023. Nueces County also sees hail and high wind, so the outdoor unit needs a spot and a setup that can take a real storm, not just a mild season.

Texas requires HVAC contractors to hold a state license.
The state tests HVAC contractors before they can hold this license, and TDLR keeps the record of who passed and who is licensed to work. That license belongs to the contractor, not to any one job, so it tells you the person or company was checked once, not that this particular installation was inspected.
For the actual install, the protection on this job comes from the local building office. Most cities and counties in Texas require a permit before an air conditioner is replaced, and an inspection once the work is done, and that inspection is what confirms this specific job was done right.

- What size air conditioner does my house need?
- There's no single number that applies to every house, since it depends on the square footage, the ceiling height, how much shade the walls get, and how well the attic is insulated. A unit that's too big cools the air fast but shuts off before it pulls the humidity down, so the house feels damp. One that's too small runs constantly during a Corpus Christi summer and still can't keep up when the afternoon high hits 94. A contractor works this out with a load calculation on your actual house, not a rule of thumb based on square footage alone.
- Should I replace the whole system or just the outdoor unit?
- If the indoor coil and outdoor unit were installed together and are close in age, replacing just the outdoor unit usually causes problems down the road. The two are matched to work at a certain capacity and refrigerant charge, and pairing a new condenser with an old coil can mean poor cooling and added strain on the compressor. Some manufacturers will also deny warranty coverage on a new outdoor unit if it's matched to an old indoor coil. A contractor can check the age and condition of both and tell you whether a matched pair makes sense for your system.
- Do HVAC contractors in Corpus Christi 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. It's worth asking to see that license before work starts on your home.
