Seven months of Texas heat wears on your AC

Your air conditioner runs from April through October here, with summer afternoons averaging 90°F. That is seven straight months where the compressor barely gets a break, cycling on and off all day just to keep up.

That kind of runtime wears on parts you cannot see from the thermostat. The refrigerant charge drifts low. The condenser coil outside cakes with dust and grass clippings and loses its ability to shed heat. Electrical connections loosen from the constant cycling. A tune-up checks the charge, cleans the coil, and tightens what has worked itself loose, before any of it forces the system to shut down on the hottest day of the year.

Texas requires HVAC contractors to hold a state license.

The Texas Department of Licensing and Regulation issues that license, and it belongs to the contractor rather than to any single visit. The state tested that contractor and keeps a record of them, and that record stays attached to them from one job to the next.

For a maintenance visit, that license is what stands behind the person working on your air conditioner. If the technician needs to open the refrigerant side of the system, checking the charge or looking for a leak, federal law also requires them to hold EPA Section 608 certification, the same rule that applies in every state. That certification is separate from the Texas license. One says the state tested and tracks this contractor. The other says the person touching the refrigerant is federally certified to handle it.

What does AC maintenance include?
A technician checks refrigerant pressure, cleans the outdoor coil, and tests the capacitor and contactor that start the compressor. They also check the blower motor, inspect the electrical connections, and change or check the filter. Outside, the coil gathers dirt and grass clippings all season, and a dirty coil makes the whole system work harder to cool the same air. Inside, they check the drain line, since a clogged one can back up and leak into the house.
How often does an air conditioner need maintenance?
Once a year, ideally in spring before the cooling season starts. Homes here run their AC from April through October, seven months of the year, so the system gets far more hours of work than it would somewhere cooler. A spring check catches a weak capacitor or a low refrigerant charge before the first 90-degree afternoon puts real strain on it.
Is AC maintenance worth it?
Yes, because most of what causes a breakdown shows up earlier as a small warning sign. A weak capacitor, a dirty coil, or a refrigerant leak all give some notice before they cause the system to quit outright. Catching those in spring, before seven months of cooling season starts, means fewer surprises once the heat sets in. It also matters here because of storms. Ten years of records show 19 hail events and 48 damaging wind events in this area, and a maintenance visit is a chance to check the outdoor unit for bent fins or hail damage before it turns into a bigger repair.
