Your system works year round in Travis County
Seven months of cooling and five months of heat means your system barely gets a break. Summer afternoons average 95°F, and the AC has to hold that back for months at a stretch. The compressor runs long hours day after day, and that kind of steady load is what wears one out.
Winter nights average 40°F, cold enough that the heat still has real work to do from November through March. Most homes here heat with electricity, so when a storm knocks out power, the heat goes with it. Travis County sees its share of both winter storms and damaging wind, and a third of Texas households lost power for 24 hours or more in 2024. When the power drops and comes back, that is when you find out if your system still starts up the way it should.

Texas requires HVAC contractors to hold a state license.
Texas runs this through the Texas Department of Licensing and Regulation. The license belongs to the contractor, not to any one job, so the same license that covers a new install also covers a repair call.
For a repair on a heating and cooling system, that contractor license is the thing standing behind the work. It is issued to the business doing the job, not renewed or checked job by job, so what protects you here is TDLR's record of who holds one.

- Why is my heat not working?
- Most of the time it's the thermostat, a tripped breaker, or the furnace not getting power or gas. Check that the thermostat is set to heat and a few degrees above room temperature. If the screen is blank, look at the breaker panel before anything else. If power and settings look fine and you still get no heat, a contractor will need to check the igniter or the flame sensor.
- Why is my system running but not cooling the house?
- If air is moving but it isn't cold, the problem is usually a dirty filter, a frozen coil, or low refrigerant. A clogged filter starves the system of airflow, and when that happens the evaporator coil can ice over and stop cooling the air even though the blower keeps running. Check the filter first. If it's clean and the vents are still blowing warm air, the system may be low on refrigerant or have a failing part, and that needs a contractor to diagnose.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set correctly, has fresh batteries if it uses them, and is set to heat or cool as needed. Next check the breaker panel and any switch near the furnace or outdoor unit, since a tripped breaker or a flipped switch will stop the system cold. Look at the filter and replace it if it's dirty, since a clogged filter can cause both weak airflow and a frozen coil. If the outdoor unit isn't running, check that it has power and that nothing is blocking it. If all of that checks out and the system still isn't working, a contractor will need to look at it directly.
