Heat Pump Repair in New Boston, Michigan
New Boston is about 25 minutes from our shop in Ypsilanti. Outdoor unit iced solid, house running on expensive backup heat, or no cooling in July? We repair air-source heat pumps year-round, every brand, at one flat rate.
A heat pump in New Boston works harder than one almost anywhere else in the country, pulling heat out of 10-degree air in January and dumping it into 90-degree air in July. The components that manage that reversal, the defrost board, the sensor and the reversing valve, are the ones that fail, and they are the ones Temprasure knows. We repair every brand across Wayne County, from the dual-fuel systems in 48164 subdivisions to the standalone units with electric backup near Willow Road, and we are honest about when an old unit is worth fixing and when a new cold-climate system with rebates makes more sense.
New Boston houses and what that means for heat pump repair
New Boston and Huron Township give us a wide spread of housing in a small area. The village core along Huron River Drive and the streets behind it has 1900s to 1930s frame houses with Michigan basements or crawlspaces, retrofitted ductwork and a furnace that was replaced sometime in the 90s. Waltz is similar but older on average. The 1960s and 70s ranches and subdivisions off Middlebelt, Sibley and Hannan Roads are on block basements or crawlspaces, with single-return furnaces and add-on central air from the 80s. Out on the section roads, 1990s to 2010s acreage builds are large colonials and ranches on poured basements with two-stage furnaces, sometimes a second attic system, and a pole barn with its own heater. Water is a mix of municipal supply in the village and wells outside it, and the well water is hard. Propane is the fuel on a fair number of rural parcels, which changes the furnace and water heater options.
The newer subdivisions in New Boston have a different heat pump population: standalone units with electric strip backup, often installed by the builder as the cheapest way to meet code. These systems lean hard on the strips when anything goes wrong, and because strip heat still warms the house, the failure is invisible until the DTE Energy bill arrives. We get those calls from New Boston, MI in February, after two months of a defrost board or a low charge quietly shifting the load to the strips. The repair is usually straightforward; the money already spent is not recoverable. That is why we also push annual heat pump maintenance for these homes.
New Boston winters are long enough that a furnace runs more hours in a year here than an air conditioner runs in five. We maintain and repair the gas furnaces in the 1900s–60s river-town houses with 1990s–2010s acreage builds near Lower Huron Metropark's southern end and Flat Rock Speedway just over the line, the hot-water boilers in the older houses around the Huron River Drive corridor, and the furnaces in newer subdivisions out toward Inkster Road south of Sibley where builder-grade equipment hits its first real failures around year ten. The shop is 15 miles away, the truck carries the parts that fail, and a heating call in New Boston ends with heat on the first visit far more often than not.
Local details we plan around in New Boston
- Huron Township requires mechanical permits and inspections for furnace, AC and water heater replacements, and the inspectors are familiar with the propane installations common in the rural half.
- Well water across the township outside the village is hard and often high in iron, which shortens water heater life and scales humidifier pads quickly.
- Many properties have a pole barn or outbuilding with a unit heater or small furnace that we service along with the house.
- The Huron River and the three metroparks keep New Boston humid and foggy, and the low ground near the river floods in spring, which affects basements and crawlspaces in the village. The open farmland on the west side of the township takes winter wind across the fields with no shelter, and the township runs a touch colder on clear nights than the suburbs to the north. Tree cover in the parks and along the river gives shade but drops debris into condensers all fall.
What New Boston homeowners call about
No cooling in summer
Same as any air conditioner: capacitor, contactor, fan motor, low charge or a clogged drain. The reversing valve adds one more possibility.
Loud whoosh or hiss every few minutes
A brief whoosh at defrost is normal. Constant hissing or a loud whoosh every couple of minutes means the reversing valve is cycling or leaking internally.
Outdoor unit encased in ice
A light frost that clears every half hour or so is normal. A thick shell of ice that never melts means the defrost cycle has failed. Switch to Emergency Heat and call.

How a heat pump repair call works
Describe what it's doing
Ice, cold air, high bills, no cooling. We will tell you whether to switch to Emergency Heat or shut it off, and give you a real arrival window.
Heat-pump-specific diagnosis
Defrost board and sensor test, reversing valve operation, contactor and capacitor readings, compressor and fan amp draw, charge verified by the correct seasonal chart, backup heat and balance point checked.
Verify through a full cycle
In winter, we watch a defrost cycle complete and confirm the backup heat stages correctly. In summer, we verify temperature split and subcooling. Dual-fuel systems get the changeover tested.
Reviews from nearby homeowners
★★★★★Al & Co. came out and took very good care of me and my family. He showed up within an hour of me making contact and was able to diagnose and take care of the problem quickly and for reasonable pricing.
Heat Pump Repair questions from New Boston
How fast can you repair a heat pump in New Boston?
New Boston is about 25 minutes from our shop. Most calls are seen the same day, and in winter we prioritize homes where the backup heat is not keeping up or where someone is at risk from the cold.
Do you repair dual-fuel heat pumps in New Boston?
Yes. Heat pumps paired with a gas furnace are common in New Boston, MI. We repair the heat pump, confirm the furnace is healthy, and set the balance point so the system uses the cheaper heat source at each outdoor temperature.
Is there an extra charge for heat pump repair in New Boston at night or on weekends?
No. The dispatch fee and the flat-rate repair price are the same at any hour, any day, for every New Boston address.
Should I repair or replace my old New Boston heat pump?
Boards, sensors, contactors, capacitors and motors are worth repairing at any age. A compressor or reversing valve on a unit past 12 to 15 years usually tips toward a new cold-climate system, especially with DTE Energy rebates and the federal credit available. We show you both numbers.
Why did my winter electric bill in New Boston double?
The heat pump most likely handed off to the electric strips because of a defrost failure, low refrigerant or a misconfigured outdoor sensor. We find the cause, fix it, and verify the strips only run when they should.
Serving every part of New Boston
Heat pump trouble in New Boston, MI does not have to mean a replacement quote from someone who would rather not work on the equipment.

If the unit genuinely is at the end of its life, we will say so and show you what a new cold-climate system with rebates would look like.
