MJ HVAC Heating and Air Conditioning - Magna's Expert HVAC Services

In Magna, we frequently handle thermostat malfunctions and evaporator coil freeze-ups. A faulty thermostat can cause inconsistent temperatures and high energy bills, which we resolve by diagnosing the unit—whether it needs recalibration, new wiring, or a replacement. Evaporator coil freeze-ups are often due to airflow problems or low refrigerant; we carefully thaw the coil, then identify and correct the root cause, such as a dirty filter, failing blower motor, or a refrigerant leak, to prevent a recurrence.

Yes, we provide routine HVAC system maintenance to help extend the life of your equipment and prevent costly breakdowns. Our service includes inspecting critical components, cleaning coils, checking refrigerant levels, testing system controls, and ensuring everything operates safely and efficiently.
