HVAC Repair West Mifflin PA | Call United Air Group

First, check your home's circuit breaker panel for any tripped breakers related to your HVAC system. If that's not the issue, a common local culprit is a clogged air filter restricting airflow and causing the fan motor to overheat and shut off. Try replacing the filter. If the fan still won't run, it's best to call us. Forcing the system can cause further damage. Our technicians can quickly diagnose whether it's a faulty capacitor, motor, or another electrical issue common in our area's older systems.

Thermostat malfunctions in our climate often stem from age, dust buildup inside the unit, or wiring issues. First, ensure it's set to 'Heat' or 'Cool' (not 'Off') and the temperature is set correctly. If it's a programmable model, dead batteries are a frequent cause. For persistent problems, like the system short-cycling or not responding, it could be a faulty sensor or a wiring connection that's been disturbed. Our experts can test your thermostat's accuracy and wiring, and recommend a reliable replacement if needed, ensuring it communicates properly with your furnace and AC.

We provide 24/7 emergency service for critical failures that leave your home without heat in winter or cooling in summer. This includes immediate repairs for no heat/no cool calls, complete system shutdowns, strange noises (like grinding or banging from the air handler), refrigerant leaks, and of course, non-functioning air handler fans and thermostats. As a local company, we prioritize getting to West Mifflin homes quickly to diagnose the problem, provide a transparent estimate, and make safe, effective repairs to restore your comfort as soon as possible.
