Eleven months of run time in Laredo heat
Your AC works March through October here, eight months of summer afternoons that average 98°F. That kind of run time wears on the compressor and the fan motor, the parts that move heat out of the house all day long. When one of them starts to go, you notice the air coming out warmer than it should, or the unit running longer to get the house down to temperature.
Winter is short here, just December through February, but nights still average 47°F and most homes heat with electricity. A heat pump or electric furnace working through those cold snaps depends on power that Texas has not always kept on. Statewide, a third of households lost power for at least a day in 2024, and Webb County has seen its share of winter storms and wind events over the past ten years. When the power drops, the system stops, no matter what shape it is in.

Texas requires HVAC contractors to hold a state license.
The Texas Department of Licensing and Regulation tests and records the contractor, not the individual job. The license belongs to the person TDLR tested, and it travels with them from house to house rather than being issued fresh for each repair.
For a heating and cooling repair in Webb County, that license is what stands behind the work. If gas is involved, a bad connection is the dangerous part of the job, and the licensed contractor is the one accountable for getting it right.

- Why is my heat not working?
- Most likely the igniter, a flame sensor, or the thermostat setting itself. Gas furnaces need the igniter to glow or spark before the burners will light, and a coating of dust or a hairline crack stops that from happening. If your furnace has a pilot light, check whether it blew out. With winter lows here averaging 47°F, a furnace that will not fire is worth a same-day look rather than waiting it out, since 85% of homes here heat with electricity and a tripped breaker after a power blip is also worth checking first.
- Why is my system running but not cooling the house?
- The blower is moving air, but something between the air and the cold is missing. Check the air filter first. A filter clogged with dust chokes off airflow across the indoor coil, and in Laredo summers with afternoons near 98°F that alone can keep a house from cooling down. If the filter is clean, the next likely cause is low refrigerant from a leak, or ice built up on the outdoor unit, both of which need a contractor to fix.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to cool or heat as needed and the batteries are not dead. Next, check the air filter and swap it if it is gray or clogged, since restricted airflow is one of the most common reasons a system runs without doing its job. Then look at the breaker panel. A tripped breaker will stop the system cold and is easy to miss, especially after a storm knocks out power, which happens often enough here that Texas saw a third of households lose power for at least a day in 2024. If all of that checks out, a licensed contractor can diagnose what is left.
