Takes about a minute. No obligation.
Homes in Gloucester County, NJ run heat about seven months a year, from October through April. A heat pump working through that kind of winter is running its refrigerant circuit hard: capacity drops as outdoor temperatures fall, so the compressor cycles more often and works against a steeper pressure differential than it would on a mild day. The reversing valve, which is specific to heat pumps and has no equivalent in a furnace, toggles every time the system switches modes and accumulates wear across every cold month. A contractor diagnosing a refrigerant or heating fault here looks at those two components before anything else.
Half the homes in Gloucester County, New Jersey were built in 1980 or earlier (2020-2024 ACS 5-year). A house built to that point in time was not wired or ducted with a heat pump in mind. When a contractor opens the unit, what they find inside tells them whether the system has been maintained to compensate for that gap or left to accumulate the strain of it. Corroded contacts, worn capacitors, and refrigerant lines that have never been properly checked are common findings. Parts availability on equipment that old varies, and a thorough diagnosis has to account for that before any repair scope is set.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is the first thing a contractor looks at when a heat pump stops moving heat, because it is the part doing the hardest work. The condenser coil wraps around it and is a common source of trouble when it is dirty or bent.
Inside the house, the air handler holds the evaporator coil and the blower fan, which pulls air across the coil and pushes it through the home. The expansion valve sits between the two coils and controls refrigerant flow. The refrigerant lines connecting the indoor and outdoor units are also checked, since a leak anywhere in that circuit will affect the whole system.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to the specific equipment and configuration in your home.
