Heat Pump Repair for Lebanon Homeowners

When Lebanon homeowners need heat pump repair, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Lebanon in York County — so we respond quickly and know the homes, the weather, and the codes in your area.
When your heat pump stops working or is not performing like it should, Aces Highlands provides fast, accurate diagnostics and honest repairs. We fix the actual problem — not just the symptoms.
Heat pump issues can range from simple fixes like a dirty filter or tripped breaker to more complex problems like refrigerant leaks, compressor failures, or control board malfunctions. Our technicians diagnose accurately the first time so you get the right repair without paying for unnecessary parts.
We service all major heat pump brands including GE, Hitachi, Mitsubishi, Daikin, Fujitsu, and LG. We carry common replacement parts to complete most repairs in a single visit. Regular heat pump maintenance can help prevent many common repair issues before they start.
If your heat pump is beyond repair or the cost of fixing it does not make sense, we will tell you honestly and help you evaluate replacement options.

Lebanon Homes and What They Need
Lebanon has the newest median housing stock of the York County towns Aces studied, built in 1989, with the lowest pre-1940 share at about 14 percent. Most of that growth happened after 1980, which means a lot of Lebanon's systems are reaching the age for their first major replacement rather than a full historic rebuild.
Heating and Cooling in Lebanon
Fuel oil and wood together heat the large majority of Lebanon homes -- about 67 percent on oil and 15 percent on wood, the highest combined oil-and-wood share of any town in this group -- with bottled or tank propane at 16 percent; there is no natural gas utility in town. That wood-and-oil combination is a natural fit for adding a heat pump to carry the shoulder seasons.

Getting to Know Lebanon
Lebanon was incorporated on June 17, 1767, making it Maine's 23rd incorporated town, and Wikipedia describes it plainly as 'the westernmost town in Maine.' It borders Acton, Sanford, Berwick and North Berwick on the Maine side, and Milton and Rochester, New Hampshire, on the other.
The town's population grew from about 1,150 in 1930 to more than 6,400 by 2020, with most of that growth arriving after 1980. Lebanon is drained by the Little River and the Salmon Falls River, the latter forming part of the state line with New Hampshire.
Local & Independent — Not a Franchise
We are an independent, Portland-based company, not a franchise chain routing your Lebanon job to a call center. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. That is how we keep customers calling back, one honest job at a time.
How a Heat Pump Works
- Outdoor unit — fan and compressor extract heat from outside air
- Reversing valve — switches the system between heating and cooling
- Line set — carries hot, high-pressure refrigerant indoors
- Indoor coil — releases heat into the airstream
- Warm air — the blower delivers it to the room

He was very friendly. He gave me an honest explanation on why I shouldn't recharge my A/C unit and what he suggested made much more sense. He really took care of everything. He is very professional, always called me with updates. 5 stars is not enough — I give this company 10 stars.

I've had three HVAC issues over the past two years. Each time I call, Elija or the office picks up the phone, and my problem is fixed in 24 hrs. Their solutions always feel correct and honest. I cannot recommend them more.

We highly recommend Highlands Heating & AC. They are extremely responsive, knowledgeable and do great work. Our boiler stopped working and Elijah was quick to respond after hours on a Friday. He installed a new boiler and heat pump hot water heater.

Heat Pump Repair FAQs
Why is my heat pump covered in ice?
Light frost on the outdoor coil is normal — the unit runs periodic defrost cycles to clear it. Solid ice that never clears is not normal, and usually points to a failed defrost sensor or board, low refrigerant, or blocked airflow. Shut the unit off and have it diagnosed before the ice damages the fan or coil.
Why is my heat pump blowing cold air in heat mode?
Check the remote is actually in heat mode and the filters are clean first. If those are fine, the usual causes are low refrigerant from a leak, a failing reversing valve, or a compressor issue — all of which need a technician with gauges to confirm.
How much does heat pump repair cost?
Simple fixes like condensate clogs, sensors, or capacitors are commonly a few hundred dollars. Board replacements and refrigerant leak repairs cost more, and we always quote before we repair, so you can decide with the real number in front of you.
Do you service heat pumps you did not install?
Yes. We repair all major brands — GE, Hitachi, Mitsubishi, Daikin, Fujitsu, LG and others — regardless of who installed the system.
Is it worth repairing a 10-year-old heat pump?
Often yes, if the repair is minor and the system was installed well. Past 12–15 years or facing a compressor or major refrigerant repair, replacement usually makes more financial sense — especially with Efficiency Maine rebates lowering the cost of a new system. We give you both numbers and let you choose.
