HVAC Repair Norwalk OH | Call Erie Mechanical

This is a common issue we see locally, often caused by a faulty reversing valve. This valve is crucial for changing the flow of refrigerant to provide heating or cooling. It can become stuck due to wear, debris, or electrical failure. Our technicians will diagnose the valve and the associated controls to determine if a repair or replacement is needed to restore proper function to your system.

Uneven temperatures are frequently a sign of thermostat malfunction. The sensor may be inaccurate, the unit could be poorly located (e.g., in direct sunlight or a drafty hallway), or internal wiring may be failing. We'll test your thermostat's calibration, assess its placement, and check the connections to your HVAC system to ensure it's sending the correct signals for consistent comfort throughout your home.

First, check your home's circuit breaker and the system's power switch. If power isn't the issue, the problem often lies with the thermostat or a safety control switch within the furnace or air handler. Our experts will perform a systematic diagnosis to pinpoint the failed component—whether it's a simple thermostat battery, a blown fuse, or a more complex control board issue—and get your system running safely again.
