Heat pump repair for Orono and the Greater Bangor area, from a crew that diagnoses the actual failure before replacing parts, so a short-cycling or iced-up system gets fixed once instead of patched.
We at One Stop Home Repair have repaired heating and cooling equipment across the Greater Bangor area since 1980, according to the company’s own history. A repair call is usually more urgent than an installation, since it often means a home has no heat or no cooling right when the weather makes that matter most.
Because our crew covers electrical and plumbing alongside heating and cooling, a repair that turns out to involve a bad electrical circuit or a condensate line tied into the home’s plumbing gets handled on the same visit rather than referred out to a second contractor. That range also means a repair visit can catch a problem before it becomes an emergency, since a technician looking at a heat pump’s electrical connections will flag a loose connection or an aging breaker even when that was not the original complaint.
Every heat pump repair is backed by our Best Price Guarantee and covered by insurance, and our technicians hold the certification the work legally requires. Refrigerant is regulated, and handling it, whether recovering it, adding to it, or repairing a leak, requires an EPA Section 608 certified technician, which is why a homeowner topping off refrigerant on their own both breaks the law and usually just delays finding the actual leak.
A heat pump that is icing over, short cycling, or blowing air that is not warm or cool enough almost always traces back to one of a small number of causes: low refrigerant charge from a leak, a failing defrost control, a dirty outdoor coil restricting airflow, or a component in the reversing valve that has started to fail. We start every repair call with a diagnosis rather than a guess, checking refrigerant charge, electrical components, and airflow before recommending a fix.
Age and refrigerant type both affect the repair versus replace decision. Systems still running older R-410A refrigerant can usually be repaired and recharged, but a unit old enough to be near the end of its rated service life, combined with a major component failure like a compressor, is often a case where replacement makes more financial sense than a repair that only buys a season or two.
Cold weather adds its own failure pattern. Every heat pump has a balance point, the outdoor temperature below which the unit can no longer keep up with a home’s heat loss on its own, and a system that seems to be struggling on the coldest days may simply be operating exactly as designed and relying on backup heat, rather than malfunctioning. We check whether a cold weather complaint is a genuine repair issue or a normal balance point limitation before recommending any work, since replacing parts on a system that is working correctly does not fix a comfort problem that backup heat is supposed to cover.
If your system needs a full replacement rather than a repair, see our heat pump installation page. For a furnace or boiler acting up instead of a heat pump, our heating system repair page covers that work, and homes with a separate central air system can see our AC repair page.
Regular heating and cooling maintenance catches many of these problems before they turn into a no heat or no cooling call.

Ice buildup on the outdoor unit usually means the defrost cycle is not clearing it properly, which can come from a failing defrost control, a low refrigerant charge, or restricted airflow across the coil. We check all three during a diagnostic visit rather than assuming which one caused it.
Short cycling is most often caused by a refrigerant charge that is too low or too high, a failing compressor, or a thermostat and control issue that is misreading the home’s temperature. Short cycling wears down the compressor faster than normal operation, so it is worth having diagnosed rather than ignored.
The answer depends on the unit’s age, the specific failure, and whether it still uses refrigerant that remains available and affordable. A minor electrical or control repair on a unit with years of life left is usually worth doing, while a major compressor failure on an aging system is often the point where replacement makes more sense, and we will lay out the real cost comparison rather than pushing one option.
No. Refrigerant work requires EPA Section 608 certification by law, and a system that is low on refrigerant has a leak somewhere that will not go away by adding more. Topping off refrigerant without finding and fixing the leak just delays the same repair and adds cost later.
We treat a no heat or no cooling call as a priority and work to get a technician out quickly, particularly during the coldest and hottest stretches of the year when a working system matters most. Call for current availability, since response time varies with weather-driven demand.
Repairs are backed by our Best Price Guarantee, and any parts we install carry the manufacturer’s own warranty terms, which vary by part and by how the original system was registered. We can confirm the specific warranty coverage for your system’s parts at the time of repair.

I’ve relied on Howard and the folks at One Stop for decades at three different locations in Orono. That probably says it all in terms of customer satisfaction.

I have zero plumbing experience and needed a bunch of work done to a shower in my home. Upon first search on Google I found One Stop Home Repair.

The service I got was prompt and they are very nice people to deal with. My heat pump went within a day, they put a new one in for me. Their plumber Eric did a super job.

The December 18 storm caused a 3000 pound branch to fall on two cars and the garage as well as tearing shingles from the house. I called them at 8 AM and they had a crew there at 10 AM.
