Nine months of cooling, three of heat, and storms in between
Your air conditioner is the machine doing most of the work here. It runs March through November, nine months a year, against summer afternoons averaging 94°F. That kind of stretch means long run times day after day, and the compressor and the fan motor are what wear down under that load. When one starts to go, you notice the house not quite reaching the temperature you set, or the unit running long after it should have shut off.
Winter is short, just December through February, but nights averaging 50°F still mean the heat has to come on, and most homes here run on electric heat. When storms take the power out, and a third of Texas households lost power for at least 24 hours in 2024, that system stops cold until it's back. Nueces County has seen 8 winter storms and 85 damaging wind events over the past ten years, and wind and power loss are hard on a system that already runs most of the year.

Texas requires HVAC contractors to hold a state license.
The Texas Department of Licensing and Regulation tests contractors before they can hold this license, and it keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license is what stands behind a heating repair today and an air conditioning repair next summer.
For a repair on a system that burns gas and moves refrigerant, that state license is what's accountable for the work here. The gas connections are the part worth getting right, since a loose fitting or bad joint is where the danger is, and in Texas that work falls under the same licensed contractor the state has already tested and recorded.

- Why is my heat not working?
- Most heat failures come down to power, gas, or airflow. Most homes here heat with electricity, so a tripped breaker or a blown fuse is worth checking first. If the system runs but blows cold, the igniter or the flame sensor is a common culprit on gas furnaces, and a dirty filter can choke off airflow badly enough that the unit shuts itself down to protect the heat exchanger. A contractor can test the parts that need a meter to check.
- Why is my system running but not cooling the house?
- If the outdoor unit and indoor blower are both running but the air coming out isn't cold, the system is likely low on refrigerant or the coil is frozen over. A dirty filter or blocked return can starve the coil of airflow until ice builds up on it, and once that happens the system needs time, sometimes with the fan running and the compressor off, before it can cool again. Summer afternoons here average 94°F, so a system stuck in this state can fall behind fast. A refrigerant leak won't fix itself and needs a contractor to find and seal it.
- What can I check before calling for HVAC repair?
- Start with the filter. Hold it up to a light and if you can't see through it, replace it. Check the thermostat is set to heat or cool as needed and has power, and check your breaker panel for a tripped breaker, especially after a storm. If the outdoor unit isn't running at all, look for a nearby breaker or shutoff switch that may have been bumped or tripped. Wind events are common here, with 85 recorded over the past ten years, so a breaker tripped by a power surge is worth ruling out before anything else. Beyond that, a contractor will need to diagnose the system directly.
