William Mechanical | HVAC Services in Medford, NJ 08055

Yes, that's a very common issue in our area. The evaporator coil, located inside your air handler, absorbs heat from your home's air. Over time, dust and debris from normal operation can coat the coil, acting as insulation and preventing proper heat transfer. This forces your system to run longer, increasing energy bills and reducing cooling power. A William Mechanical technician can perform a professional cleaning to restore efficiency and improve your indoor air quality.

The reversing valve is crucial for switching between heating and cooling modes. Key signs of a problem include the system blowing cool air when set to heat (or warm air when set to cool), the unit being stuck in one mode, or unusual hissing sounds. Given our variable South Jersey seasons, a faulty valve can leave you uncomfortable. Our technicians are trained to diagnose valve issues accurately and perform the necessary repair or replacement to restore full function to your heat pump.

Scheduled maintenance is the best defense against the specific HVAC problems we see in Medford homes. During a tune-up, we clean critical components like the evaporator coil to prevent efficiency loss, check the operation of the heat pump's reversing valve, and test the entire system for early signs of wear. This proactive approach from a local expert helps catch small problems before they become major, costly repairs, extends your system's lifespan, and keeps your energy bills predictable throughout the year.
