Boiler running but some zones stay cold
A stuck zone valve, failed circulator or air in the lines often leaves part of the house without heat.
Boiler RepairHastings has two very different housing stories, older homes near the historic downtown and newer houses on the edges of town, and each one calls for a different kind of heating work.

Hastings is the county seat of Barry County, a small city on the Thornapple River northeast of Kalamazoo. Our technicians head up from the Kalamazoo office to repair and replace hot-water boilers, install heat pumps, service central air and handle furnace repairs. Each call is answered and completed by our own people, so the technician you meet is the one responsible for the result.
In 49058, a single week might include a radiator system in a century-old house and a heat pump setup in a newer subdivision. We treat them as separate trades within the same job. Older systems need careful repair with matched parts, while newer homes often want better efficiency and quieter comfort from what they already own, plus cooling that keeps up with humid July afternoons.
Near the historic downtown, many homes are older two-story houses, some still heated by cast iron boilers feeding radiators or baseboard. Those systems hold heat well, but they rely on circulator pumps, zone valves and expansion tanks that wear with age. When the boiler itself is near the end, a modern high-efficiency boiler replacement can reuse the existing radiators and piping, which keeps the comfort of hydronic heat without tearing up floors.
Newer houses around the city usually run a gas furnace and a central air condenser on shared ducts, and more owners now ask about putting in a cold-climate heat pump alongside it. A heat pump can handle cooling in summer and much of the heating in spring and fall, with the furnace as backup during deep cold. Before suggesting a size, we check the home's ducts, electrical panel and insulation, since an oversized heat pump short cycles.

Hastings winters bring long cold stretches and nights below zero, which is when boilers and furnaces work their hardest and worn parts tend to give out. River valley air can also hold moisture through spring and fall, and basements near the water run damp. In summer, humid heat makes central air and heat pumps run long cycles, so a weak capacitor or a dirty outdoor coil shows up as warm rooms on the hottest afternoons.
Our technicians reach Hastings from the office at 327 S Rose Street in Kalamazoo, driving north through Barry County. Our staff answers (269) 360-5258 through the night and on every holiday. For boiler calls, it helps to tell us whether the system feeds radiators, baseboard or radiant floors, and how many thermostats or zones the house has, so the right parts ride along.
Common calls
A stuck zone valve, failed circulator or air in the lines often leaves part of the house without heat.
Boiler RepairA high-efficiency boiler can connect to your existing radiators and piping, plus outdoor reset controls that lower water temperature on mild days.
Boiler Installation & ReplacementWe size a cold-climate heat pump to the house and pair it with your furnace for the coldest weeks.
Heat Pump InstallationA failed capacitor, contactor or low refrigerant charge is the usual cause, and we test before replacing parts.
AC RepairRadiant floor heating or a hydronic zone off the boiler warms a lower level more evenly than a ducted register.
Radiant Floor HeatingFAQ
Usually. The cast iron radiators in older Hastings homes usually outlast several boilers. We flush the system, check the piping for leaks and connect a modern boiler sized to the radiators and the house. That keeps original fixtures in place and avoids opening walls or floors.
For a Hastings home with existing ductwork, a ducted cold-climate heat pump typically runs about $7,280 to $13,940 installed, depending on size, efficiency and electrical work. Pairing it with a current gas furnace can keep the cost toward the lower end. The technician sets the final price after a visit.
Many newer Hastings homes are good candidates, since they often have tight construction, sized ductwork and modern electrical service. A heat pump can cover cooling and much of the heating season, while the gas furnace takes over during deep cold. We check your ducts and panel before recommending one.
