Heat pump blowing cool air in winter
Often it is defrost mode doing its job. If it lasts longer than a few minutes, we check the reversing valve, sensors and refrigerant charge.
Heat Pump RepairMore Winchell homeowners are adding a heat pump beside the gas furnace, and they want someone who can set the two up to share the work through a Michigan winter.

The Oakland/Winchell neighborhood sits on Kalamazoo's southwest side, near Asylum Lake. Many homes here started with a gas furnace and central air, and when the air conditioner reaches the end of its life, owners now ask whether a heat pump makes more sense. It cools like an air conditioner in summer and also heats the house through fall and spring.
Our technicians install, repair and service heat pumps in 49008, and we keep working on the furnaces they pair with. We explain how a dual-fuel setup decides which one runs, what the balance point means for your bills, and how the outdoor unit should behave in a snowstorm. You get a straight answer on whether the switch fits your house before anything is ordered.
A typical setup in this part of the city is a gas furnace in the basement feeding metal ductwork, with a condenser outside. Swapping that condenser for a heat pump reuses the existing refrigerant line route and ducts, and the furnace stays in place as backup. The heat pump covers mild days, and the furnace takes over when the outdoor temperature falls too low for the heat pump to keep up efficiently. A dual-fuel system runs that handoff on its own.
Getting the handoff right is most of the job. The thermostat needs the correct wiring and settings, the outdoor unit needs proper clearance from snow and drip lines, and the duct system has to move enough air for the heat pump to work well. Our technicians check airflow before installing, because a heat pump on undersized ducts will run long and deliver lukewarm air. We set the switchover point with you after looking at the house.

Kalamazoo has long stretches of 30 to 50 degree weather in October, November, March and April, and those are the months a heat pump earns its keep. Once lake-effect snow and nights below zero arrive, the gas furnace carries the load. Heat pumps also run a defrost cycle in cold, damp weather, sending a cloud of steam off the outdoor unit for a few minutes. That is normal, and knowing it ahead of time saves a worried call at 6 a.m.
Winchell calls are handled from our main Kalamazoo office downtown, a short drive southwest. When you call (269) 360-5258, a person answers around the clock and on holidays. For a new heat pump, a technician comes out to measure and talk through options, and that replacement estimate visit has no charge. For a repair, you get the price after diagnosis, before any work.

Heat Pump RepairWe measure the house, check the ducts and set up the new unit to work with your existing furnace.
Heat Pump InstallationA failed defrost board, a stuck fan or a low charge lets ice build up. Our technicians clear it safely and fix the cause.
Heat Pump RepairWrong thermostat settings or wiring can run both at once. We correct the controls and set a sensible switchover temperature.
Dual-Fuel Heating SystemsThe furnace may sit idle for weeks in fall, then fail on the first hard freeze. We repair the igniter, sensor or control.
Furnace RepairFAQ
A modern heat pump heats well into the 20s and lower, though it works harder as the temperature drops. In Winchell most homeowners pair it with their gas furnace, so the furnace takes over in the coldest weather. That gives you efficient heat in fall and spring and strong heat on below-zero nights.
Adding a heat pump to an existing gas furnace in this area typically runs between $5,870 and $10,940, depending on size, efficiency and any duct or electrical work. A full dual-fuel package with a new furnace costs more. We give you a written number after measuring the house and checking the ducts.
That is the defrost cycle. On cold, damp days frost builds on the outdoor coil, and the heat pump briefly reverses to melt it, which releases steam. It usually lasts a few minutes. If the unit stays iced or the steam never stops, call us and a technician will check the controls and charge.
