Metro Filter Service | Emergency HVAC Repair in Oklahoma City, OK

Common signs include your AC running constantly but not cooling effectively, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound from the outdoor unit. In our climate, a leak can drastically reduce efficiency and strain your system. If you notice these symptoms, it's best to call for a professional diagnosis to prevent further damage and restore proper cooling.

This is often due to a faulty reversing valve, a key component that changes the flow of refrigerant for heating vs. cooling. Oklahoma's temperature swings mean this valve cycles frequently, which can lead to wear or electrical failure. If your system is stuck in one mode or isn't producing the desired temperature, our technicians can test the valve and related controls to get your system properly switching again for year-round comfort.

Regular professional maintenance is crucial for our local climate. Our tune-ups include checking refrigerant levels to catch small leaks early, inspecting electrical components like the reversing valve solenoid, and cleaning the system to ensure optimal airflow. This proactive care helps prevent the sudden breakdowns from common issues, improves energy efficiency to combat high utility bills, and extends the overall life of your HVAC equipment.
