The ACS estimates about 91% of Cibolo homes heat with electricity, the highest share of any area we cover. The survey does not separate heat pumps from electric furnaces, but in a market this electric, many households rely on a heat pump for both summer cooling and winter heat.
Heat pumps in a hard freeze
Freezes are rare, about 14 nights a year at or below 32 °F at the San Antonio airport, but they test heat pumps. In February 2021 the airport fell to 9 °F during a 9-day freeze run, and more than 300,000 people in Bexar County lost power (KSAT). Heat pumps lose capacity in single digits and lean on electric strip heat.
In the January 2026 cold snap, a San Antonio contractor told News4 San Antonio most calls involved heat pumps struggling to keep up, and that defrost cycles made owners think the system had stopped working. Read heat pumps in a Texas freeze.
Refrigerant and efficiency at replacement time
For homes from the 2010s, the refrigerant question comes up at replacement time. Existing R-410A systems can still be repaired. New residential split systems must use a lower-GWP refrigerant such as R-454B or R-32, and a new split heat pump must meet at least 14.3 SEER2 and 7.5 HSPF2 under DOE rules for Texas. Ask each contractor which refrigerant and efficiency rating the quoted unit uses.

Cibolo heat pump and HVAC questions
Why does my heat pump make loud noises and steam in winter?
That is usually defrost mode. In cold, damp weather ice builds on the outdoor coil, and the heat pump briefly reverses to melt it, which can sound loud and release steam. During the January 2026 cold snap a San Antonio contractor said many owners panicked at this and assumed the system had failed. Call a contractor if the coil stays iced.
What is emergency heat on my thermostat?
Emergency or auxiliary heat uses electric resistance strips instead of the heat pump. It runs automatically when the heat pump can’t keep up in a hard freeze, and it costs more to run. Using it all the time, or seeing it run on mild days, is a reason to request a heat pump inspection.
Do I need a permit to replace my AC or heat pump in Cibolo?
Check with the city. Cibolo Building Permits and Inspections requires contractor registration and an online account before a permit application, and it uses the 2021 International codes with local amendments. The contractor you hire should handle the permit for a replacement. This is general information, not legal advice.
