Collins Heat & Air - Broken Arrow's Reliable HVAC Services

Common signs in our area include your system blowing cool air when set to heat, blowing warm air when set to cool, or getting stuck in one mode. This valve is crucial for switching between heating and cooling. Our technicians can test the valve's solenoid and pressure to diagnose the issue and perform an accurate repair to restore proper function.

We start with a thorough inspection using electronic leak detectors, ultraviolet dye, or nitrogen testing to pinpoint even small leaks, often in coils or connections. Once found, we repair the leak, perform a vacuum test to ensure the system is sealed, and then recharge it with the precise amount of refrigerant specified by the manufacturer. Simply topping off refrigerant without fixing the leak is illegal, ineffective, and costly.

This frequent local issue can stem from several problems, including low refrigerant from a leak, a failing reversing valve on a heat pump, or a malfunctioning compressor. It often indicates your system is struggling and working inefficiently. We'll perform a comprehensive diagnostic to identify the root cause—whether it's a repair issue or a sign your system is undersized—and provide a clear solution.
