Heat pump iced over in winter
We check the defrost board, sensors and refrigerant charge, and look at whether the unit needs to sit higher above the snow.
Heat Pump RepairSt. Joseph homes on the Lake Michigan shore deal with damp lake air, heavy snow bands and late, cool springs, and all three change how heating and cooling equipment wears.

St. Joseph is the Berrien County seat, a city on Lake Michigan at the mouth of the St. Joseph River. It is served from our Coloma office rather than Kalamazoo, which keeps drive times short for repairs, tune-ups and new installs on this side of the region. Our technicians work on year-round homes here as well as seasonal cottages and rental properties near the water.
Heat pumps have become a common request in St. Joseph, both as a full replacement for an aging air conditioner and as a companion to an existing gas furnace. Along the shore, a heat pump earns its keep during the long, cool shoulder seasons, when the lake holds spring temperatures down and keeps fall mild well into October and beyond.
Year-round houses in St. Joseph mostly run a natural gas furnace with central air or a heat pump, with equipment in a basement or a utility closet. Damp lake air is hard on all of it. Steel cabinets rust from the bottom up, outdoor coil fins corrode, and electrical connections in the outdoor unit loosen and pit over time. Our technicians check terminals, contactors and coil condition on every visit along the shore.
Seasonal cottages and rentals near the water bring other needs. Some sit empty for months, and a furnace that has not run since April may not light in October. Others change hands often, and nobody knows when the filter was last changed. A spring startup and a fall check before the property closes, with a heat pump repair or furnace fix handled on the spot, keeps those properties ready for the next stay.

St. Joseph gets heavier lake-effect snow than inland towns, and wind off the lake drives it against outdoor units and side-wall vents. Heat pumps need clear space around the outdoor coil to defrost properly, so a unit sitting low in a drift can ice over and fall behind. Spring comes late on the shore because the lake stays cold, which stretches the heating season. Summer is humid, and the moist air coming off the water makes moisture removal a real part of cooling comfort.
St. Joseph is served from our office at 340 Washington St. in Coloma, a short drive up the shore, so technicians reach you without crossing the whole region. Calls to (269) 360-5258 are answered 24/7, every day of the year, holidays included. For rental and cottage owners who are out of town, we can coordinate access to the property and report back by phone on what we found.

Heat Pump InstallationFAQ
St. Joseph is covered from our Coloma office at 340 Washington St., not from Kalamazoo. That keeps the drive short for repairs and installs along the Berrien County shore. You still call the same number, (269) 360-5258, at any hour, and the call is routed to the technicians working the lakeshore side.
In many St. Joseph homes it does, because the lake keeps spring and fall cool for a long stretch, and heat pumps are efficient in that kind of weather. Paired with a gas furnace for the coldest days, it can lower heating costs. We look at your ducts and electrical service before recommending one.
Most heat pump repairs in St. Joseph fall around $197 to $684, covering parts such as capacitors, contactors, defrost boards and sensors. Refrigerant leaks and reversing valve failures cost more. Our technician explains what failed and gives you a price before starting, and the final cost depends on what the inspection finds.
