Bexar County runs the system almost year round
Seven months of cooling and five months of heat means the system in your house rarely gets a real break. Summer afternoons averaging 95°F push the compressor hard, day after day, and that steady load wears on it faster than a few hot spells would. Winter nights averaging 43°F are not brutal, but most homes here heat with electricity, and that equipment still cycles on and off all night to hold the house steady.
The bigger risk is the storm. Bexar County has logged 104 damaging wind events and 5 winter storms over the past ten years, the kind of weather that knocks out power across the region. When most homes depend on electricity to heat, an outage does not just mean no lights. It means no heat, and in a hard freeze, that is when pipes and equipment take the damage.

Texas requires HVAC contractors to hold a state license.
The Texas Department of Licensing and Regulation issues this license and keeps the record of who holds it. That license belongs to the contractor, not to the job, so the same license covers a furnace repair, a coil replacement, or any other work on your system.
For a repair like this, that license is what stands behind the person working on your system. Texas does not split out gas work or refrigerant work into a separate credential on this page's facts, so the contractor's license is the one thing to point to here.

- Why is my heat not working?
- Most often the thermostat is calling for heat but the furnace or heat pump isn't answering. If you have a gas furnace, check whether the pilot or igniter is lighting at all. If nothing lights, a safety switch may be holding the system off. Most homes here heat with electricity, so a tripped breaker or a heat pump stuck in defrost can also be the cause. A contractor can tell you which one it is.
- Why is my system running but not cooling the house?
- The system is running but the air coming out isn't cold, which usually means airflow or refrigerant. Start with the filter. A clogged filter starves the coil of airflow and the coil can freeze over, and a frozen coil blows warm air even though the blower is on. If the filter is clean and the air still isn't cold, low refrigerant from a leak is the next likely cause, and that's not something to add yourself. On a 95°F afternoon a system fighting either problem will struggle to keep up no matter how long it runs.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to heat or cool as intended and that the batteries aren't dead. Check the filter next and replace it if it's dirty, since a blocked filter causes problems in both winter and summer. Then check your breaker panel for a tripped breaker, especially after a storm. If the outdoor unit is covered in debris or leaves, clear it. If none of that fixes it, a licensed contractor can take it from there.
