Dennis Cool It Down Air Conditioning Heating & Refrigerat: Experienced HVAC Repair Serving Baytown, TX 77522

This is a common issue we see in Baytown, often caused by a faulty heat pump reversing valve. This valve is crucial for switching your system between heating and cooling modes. When it fails, your system gets stuck. Our technicians can diagnose the valve, perform necessary repairs or a replacement, and get your system properly switching modes again for year-round comfort.

This frequently points to a refrigerant leak, which reduces your system's cooling capacity. As refrigerant levels drop, your AC has to work much harder and longer to try to reach the set temperature, often without success. We'll perform a leak detection test, locate the source, repair it, and recharge your system with the correct amount of refrigerant to restore efficient, powerful cooling.

For our Baytown weather, biannual maintenance is key. Before summer, we focus on cleaning coils, checking refrigerant levels and pressures to catch leaks early, and ensuring the reversing valve on heat pumps is functioning. Before winter, we verify heating operation and valve function again. This proactive care helps prevent the sudden failures we commonly repair, saving you from discomfort and more costly emergency fixes.
