Year-Round Heating and Cooling From One System

Heat pumps provide both heating and cooling from one efficient system, making them an increasingly popular option for homes throughout Central New Jersey. MSI Plumbing and Remodeling provides heat pump repair, maintenance, and installation throughout Lebanon, NJ and the surrounding area.


Whether your existing system is not keeping up, your energy bills are climbing, or you are considering a heat pump for the first time, we’ll evaluate your home and help determine whether repair, replacement, or a different HVAC solution makes the most sense.

Signs Your Heat Pump Needs Attention

Because a heat pump operates during both heating and cooling seasons, it often works more months of the year than a traditional air conditioner. Changes in performance are worth addressing early. Watch for:

  • Unusual grinding, squealing, rattling, or buzzing sounds
  • Heating or cooling that feels weaker than usual
  • Uneven temperatures throughout your home
  • System cycling on and off frequently
  • Rising electric bills without a clear explanation
  • Weak airflow from supply vents
  • Outdoor unit icing excessively or not defrosting properly
  • Auxiliary or emergency heat running more than expected
  • System struggling to maintain temperature during very cold weather

Some frost on an outdoor heat pump can be normal during winter operation, but heavy ice buildup or a system that never clears itself should be checked.

Heat Pumps in Central New Jersey

Central New Jersey gets hot, humid summers, freezing winter temperatures, and plenty of weather in between. A heat pump needs to be selected and sized for those real operating conditions, not just for a mild-weather efficiency rating.


Modern heat pumps can perform very well in our climate, but equipment selection, proper sizing, controls, ductwork, and backup heat strategy all matter. We evaluate the whole system before recommending whether a heat pump is the right fit for your home.
