Ten months of work a year, with power that doesn't always hold

Your system works most of the year here. Cooling runs April through October, and afternoons average 90°F, so the compressor is under load for seven straight months. Heat comes on for December through February, when nights average 48°F. That is not deep cold, but the system still has to switch from cooling to heat and back, and each switch is a chance for a weak part to fail.

More than half the homes in this area heat with electricity, so when the power goes out, the heat goes with it. Galveston County has seen 48 damaging wind events over the past ten years, and statewide, a third of households lost power for at least 24 hours in 2024. A system that comes back on by itself after an outage is one less thing to worry about. One that doesn't restart on its own can leave a house without heat or air until someone resets it.

Texas requires HVAC contractors to hold a state license.

Texas licenses HVAC contractors through the Texas Department of Licensing and Regulation. That license is held by the contractor, tested and recorded by the state before that person or company can take on HVAC work. It covers the contractor, not each job. The record follows them from one house to the next, not the repair itself.

For a repair on a heating and cooling system, that license is what stands behind the person working on your equipment. Texas puts its record on the contractor, not on the job, so what happens inside your system on the day of the repair is still covered by the license they hold.

Why is my heat not working?
Start with the thermostat. Make sure it is set to heat and set a few degrees above the room temperature, since a setting left over from summer is an easy thing to miss. If the thermostat looks right, check the breaker for the furnace or air handler, since a tripped breaker will cut heat with no other warning. Electric heat strips and heat pumps both draw a lot of power, and a breaker that trips once can trip again, so if it keeps tripping, stop resetting it and have a contractor look at it.
Why is my system running but not cooling the house?
Check the air filter first. A filter clogged with dust blocks airflow across the coil, and when that happens the coil can ice over and stop cooling the air even though the system keeps running. If the filter is clean, look at the outdoor unit and clear away any leaves or grass clippings packed against it, since it needs open air to release heat. If the unit is clear and the filter is clean and the house still is not cooling, the system likely needs a contractor to check the coil and refrigerant level.
What can I check before calling for HVAC repair?
Check the thermostat batteries and settings, the breaker for the unit, and the air filter. These three things cause a real share of no-heat and no-cool calls, and all three take a few minutes to check yourself. Also check the outdoor unit for anything blocking it, and check that the furnace or air handler's power switch has not been bumped off. If everything there looks right and the system still is not working, a licensed contractor will need to diagnose it.
