Most calls we take in a Maine summer come down to one of four faults: a failed capacitor or contactor, a refrigerant leak, a blocked condensate drain, or airflow restricted enough to freeze the evaporator coil.
One Stop Home Repair is a home services contractor based at 90 Stillwater Avenue in Orono, Maine, and by the company’s own account, we have served the Greater Bangor area since 1980. We repair cooling equipment in Orono, Bangor, Brewer, Hampden, Belfast, Bucksport, Ellsworth, Lincoln, Pittsfield, and Dover-Foxcroft.
Cooling here is a short, intense season rather than a nine-month load, and that changes what fails. Equipment sits idle from September through May, then gets asked to run hard in a July humidity spell. Start components that were marginal in the fall fail on the first hot day, and a slow leak shows up as a system that runs without reaching setpoint.
We are licensed and insured, and our cooling work is performed by technicians who hold EPA refrigerant certification. Pricing is given before work begins. We tell you what failed, what it costs to correct, and what we would do in our own house.
Call us when you notice any of the following:
Short cycling is the pattern where a system reaches its cutoff and restarts within a few minutes, and it wears a compressor far faster than steady running does.

A diagnosis starts with measurement, not a parts guess. Our technician confirms the equipment has power and the thermostat is calling, measures the temperature difference across the indoor coil, called delta T, to see whether the system is moving heat at all, then checks airflow and reads refrigerant pressures with superheat and subcooling to judge whether the charge is correct.
That sequence matters because very different faults look identical from the thermostat. A dirty filter, a failing blower motor, and a low charge can all produce weak cold air, and only one of them is fixed by adding refrigerant. If pressures indicate a leak, we locate it rather than topping the system off, because a recharge without a repair is a bill you pay again next summer.
Two things set the price of a cooling repair: which component failed, and how hard it is to reach. A capacitor is inexpensive on an accessible unit, while a leaking evaporator coil inside a ducted air handler is a much longer job.
Refrigerant handling is federally regulated, and that is the clearest line between a qualified cooling repair and an unqualified one. Under Section 608 of the Clean Air Act, the EPA requires that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants must be certified through a test administered by an EPA-approved certifying organization. The rule reaches ordinary diagnostic work: attaching and detaching gauges to read appliance pressure is a covered activity, as is adding or removing refrigerant.
That is why a do-it-yourself refrigerant top-off fails on two counts. It is work the rule reserves to certified technicians, and it treats a symptom instead of the fault. Refrigerant is not consumed by a sealed system, so if the charge is low, the refrigerant left through a leak, and the leak is still there.
Brud Folger called us about a furnace problem, so this was a heating repair rather than a cooling one, but it is the same technicians and the same diagnostic process we bring to an air conditioning failure. He wrote that the work was “Completed efficiently and professionally!” and added, “Always happy and satisfied with their help.” Read this review on Google.
An air conditioner that runs without cooling has usually lost either airflow or refrigerant charge. A clogged filter, a dirty evaporator coil, or a failing blower motor restricts airflow, while a leak lowers the charge so the system cannot absorb heat. Both feel the same at the register, so a technician separates them by measuring the temperature split across the coil and reading refrigerant pressures.
The cost depends on which component failed and how accessible it is, so a firm number comes after diagnosis rather than over the phone. An electrical component such as a capacitor sits at the low end, while leak repair, coil replacement, and compressor work sit at the high end. One Stop Home Repair quotes the repair before work begins.
Yes. Ductless mini-splits are the most common cooling equipment in Greater Bangor homes because they add cooling to houses built without ductwork. We service both the indoor heads and the outdoor units, including refrigerant faults, control boards, condensate issues, and blower problems.
Same-day service depends on how the schedule sits when your call comes in, and we tell you plainly rather than promising a window we cannot hold. Cooling failures during a hot spell are treated as priority calls, because indoor temperatures climb quickly in an unconditioned home. If we cannot reach you the same day, we give you a real appointment time.
An older system is worth repairing when the failed part is inexpensive, the rest of the system is sound, and its refrigerant is still available. It stops being worth repairing when the compressor fails out of warranty, when the same coil leaks repeatedly, or when it still runs on R-22. We price the repair and the replacement side by side.
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.
