Pfluger Heating & Air Conditioning: Trusted HVAC Services Serving Pflugerville, TX 78660

That's a common sign of a heat pump reversing valve problem here in Pflugerville. This valve is crucial—it switches the system between heating and cooling modes. When it fails, the system can get stuck in cooling, blowing cold air when you need heat. Our technicians can diagnose a faulty valve, solenoid, or wiring issue and perform the precise repair to get your heat working again.

Yes, that's a classic evaporator coil freeze-up, a frequent issue in our area. It's often caused by restricted airflow (from a dirty filter or blocked vents) or low refrigerant levels. Running the system while frozen can cause serious damage. We recommend turning it off to let it thaw and calling us. We'll find the root cause—whether it's a leak, a dirty coil, or a blower issue—and fix it to prevent a costly compressor failure.

Great question! For heat pumps, ensure outdoor units are clear of leaves and debris, especially after our windy spells. For preventing coil freeze-ups, the simplest step is changing your air filter every 1-3 months. Also, keep supply vents open and unobstructed. The best prevention is a professional maintenance check twice a year—in spring and fall. Our tune-up catches small issues like refrigerant leaks or electrical problems before they lead to a major breakdown.
