A heat pump that stops working in Menominee County has almost certainly been through real weather stress over its life. 105 severe weather events were recorded in Menominee County, Michigan between 2015 and 2024. At roughly the national midpoint for severe weather frequency, this county puts a steady but moderate load on outdoor equipment. That load accelerates wear on compressors, contactors, and refrigerant lines over years, but it rarely explains a sudden failure on its own. A contractor called out for repairs here will check for refrigerant loss, compressor health, and electrical component wear, and the honest diagnosis usually traces back to deferred maintenance or component age rather than any single weather event.
Ductwork in a house this old has been through enough heating seasons that what a contractor finds once the unit is open seldom matches what the exterior suggested. Half the homes in Menominee County, Michigan were built in 1970 or earlier (2020-2024 ACS 5-year). That history shows up inside the refrigerant circuit, across electrical contacts, and in the condition of components that do not announce their state until the panels come off. A contractor repairing a heat pump here prices the job from what the opened system actually contains, because wear at this depth of service does not follow a pattern a visual inspection can anticipate.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil, the two components a contractor reaches first when something is wrong. The compressor pressurizes the refrigerant that carries heat between indoors and out. When the system runs but produces no useful heating or cooling, one of these is usually where the fault lives.
Inside, the air handler hangs in a closet, utility room, or attic and pushes conditioned air through the house. It holds an evaporator coil and a blower motor, either of which can be the source of poor airflow, ice buildup, or warm air coming from the vents. The reversing valve, which sits in the outdoor unit, controls which direction heat moves and is a common point of failure when the system heats fine but will not cool, or the reverse.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components and conditions apply to your specific house.
