MJT Mechanical - Paramus's Reliable HVAC Services

Common signs in our area include your HVAC system not turning on/off at set temperatures, rooms feeling unevenly heated or cooled, or the thermostat display being blank or unresponsive. These issues can lead to discomfort and higher energy bills. MJT Mechanical can perform a diagnostic check to see if it's a wiring issue, a calibration problem, or if it's time for an upgrade to a more efficient model.

This is often a symptom of a failing reversing valve, a common issue with heat pumps in our Bergen County climate. The valve directs refrigerant flow to change modes. If it's stuck or leaking, your system might only blow cool air or fail to switch. Our technicians at MJT Mechanical can test the valve's solenoid and pressure, performing the precise repair needed to restore proper function.

Absolutely. Many thermostat and reversing valve problems start with electrical connections, dirt buildup, or wear that a thorough maintenance visit can catch early. Our preventative maintenance includes checking thermostat wiring and calibration, inspecting the heat pump's reversing valve operation, and cleaning components. This proactive care helps Paramus homeowners avoid unexpected breakdowns and maintain system efficiency.
