Bell County runs your system almost year round
Summer afternoons here hit 95°F, and the AC carries that load from April through October. Seven months of long run times wear on the compressor and the fan motor, the parts that don't get a break once the heat sets in.
Winter is shorter but not gentle. Nights average 39°F from November through March, cold enough that the furnace cycles on and off through the night. Add in the storms Bell County sees, wind and ice that knock out power, and a system that was already working hard gets pushed harder. Most homes here heat with electricity, so when the power drops, the heat does too.

Texas requires HVAC contractors to hold a state license.
Texas tests HVAC contractors before handing out a license and keeps a record of who holds one. That license belongs to the contractor, not to the job, so it doesn't expire when this repair is finished or transfer to whoever answers the phone at a company. The person the state tested is the person whose name is on it.
For a repair on a heating and cooling system, that license is what stands behind the work. It's the contractor's record with the state, not a sign-off on this particular repair, so it's worth knowing whose name is actually on it before the work starts.

- Why is my heat not working?
- Most of the time it comes down to power, gas, or airflow. Check that the thermostat is set to heat and the temperature is above room temperature, and check the breaker for the furnace or air handler. Most homes here heat with electricity, so a tripped breaker or a blown fuse in the air handler is a common cause. If the furnace runs on gas, make sure the gas valve is open and the pilot or igniter is working. A dirty filter can also block enough airflow to shut the system down as a safety measure, so check that next.
- Why is my system running but not cooling the house?
- If air is moving but it is not cold, the problem is usually with the refrigerant side or the airflow, not the thermostat. Start with the filter. A clogged filter starves the coil of airflow and can cause it to ice over, and once that happens the system blows warm air until the ice melts. Check the outdoor unit too. If the coil or fan is covered in debris, it cannot release heat the way it needs to. If the filter is clean and the outdoor unit is clear and you are still getting warm air, the system likely has a refrigerant leak or a failing part, and that calls for a contractor to check pressures and diagnose it.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set to the right mode, the temperature is set past room temperature, and the batteries are not dead. Check the breaker box for a tripped breaker, since a tripped breaker will stop the system cold with no other symptoms. Look at the filter and replace it if it is dark or clogged, since a blocked filter causes both heating and cooling problems. For a gas furnace, confirm the gas valve is open. If the outdoor unit is involved, clear away any leaves, grass clippings, or debris around it. If the system still is not working after these checks, a licensed contractor can diagnose what is left.
