Heat pumps work hard year round in San Marcos, and that constant use can wear down components over time. Refrigerant leaks are one of the more common culprits we see, often caused by small cracks or corrosion in the lines that develop gradually. When refrigerant levels drop, your system has to work harder just to reach the same comfort level.

Humidity plays a bigger role in heat pump performance than most homeowners realize. San Marcos summers bring thick, sticky air, and that moisture can accelerate wear on coils and electrical components if the system isn’t maintained properly. On the flip side, the occasional cold snap can cause heat pumps to freeze up if the defrost cycle isn’t working correctly.

Electrical issues, worn capacitors, and thermostat malfunctions round out the list of problems we run into most often. Some of these are simple fixes, while others point to a system that’s nearing the end of its lifespan. Either way, our technicians will walk you through exactly what’s going on before any work begins.
