Comprehensive San Antonio Heat Pump Services

Heat pumps are specialized machines that use a reversing valve to act as both an air conditioner and a heater. We are factory-trained on this specific technology to provide repairs that go beyond a standard AC fix.

• Reversing Valve & Defrost Control: These are the most critical, often misdiagnosed, parts of a heat pump. We specialize in identifying and fixing stuck valves and faulty defrost boards.

• CPS Energy Efficiency Tuning: We offer seasonal maintenance designed to optimize your system for performance and help you qualify for any applicable CPS Energy efficiency rebates.

• Specialized Ductless Mini-Split Service: San Antonio has many older homes where traditional ductwork isn't viable. We provide expert service for all major mini-split brands.

• Refrigerant Charge & Leak Repair: Improper charging can ruin a heat pump's efficiency in both summer and winter. We find the leaks and fix them right.

Key Warning Signs Your Heat Pump Needs Professional Service

San Antonio Homeowner Alert: Given our extreme usage, your system will likely show these signs before a major breakdown:

• The "Emergency Heat" light won’t turn off. This means your efficient heat pump isn't working, and your expensive electric resistance heat is doing all the work.

• Strange, grinding or squealing noises. This usually indicates a failing fan motor or compressor bearing.

• Ice buildup on the outdoor unit (in winter). While some ice is normal, complete icing means your defrost cycle has failed.

• The system is constantly short-cycling. If it turns on and off every few minutes, it is overworking and needs immediate attention.
