AC Repair for Lebanon Homeowners

Lebanon homeowners call Aces Highlands for ac repair because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on York County roads every day — we know this area's housing, weather and permit process cold.
When the cooling quits during a Maine heat wave, you need a technician who diagnoses on the first visit and quotes before starting. Aces Highlands repairs ductless mini-splits, heat pumps in cooling mode, and central air across Greater Portland.
Most Southern Maine cooling is a ductless mini-split or a heat pump in cooling mode, and failures follow a pattern: a weak capacitor, a clogged condensate drain, a dirty coil, a tripped breaker, or a slow refrigerant leak.
We service every major brand — Mitsubishi, Daikin, Fujitsu, LG, GE, and Hitachi — plus conventional central air condensers paired with a furnace. Our vans carry capacitors, contactors, condensate pumps, and common sensors, so most repairs finish in one visit.
If the unit is past 12 years, runs on phased-out R-22 refrigerant, or needs a compressor, we show you the numbers on replacement — an Efficiency Maine rebate on a new cold-climate heat pump can change that math.
Same-week appointments are the norm outside peak heat waves. Call (207) 670-8616, tell us what the unit is doing, and we will say whether it can wait or needs a same-day visit. Regular maintenance prevents most of these calls.

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
Aces Highlands is a locally owned Portland, Maine company serving Lebanon — not a national franchise. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. We show up, fix the actual problem, and let the work speak for itself.
How Central Air Conditioning Works
- Condenser — outside, rejects heat picked up indoors
- Compressor — pressurizes the refrigerant gas
- Evaporator coil — at the furnace, absorbs heat from indoor air
- Blower — pushes air across the cold coil
- Cool air — delivered through the ducts

Why Central AC Fails Mid-Summer (And What We Check First)
AC failures cluster on the hottest days for a mechanical reason, not bad luck — a system running at its rated limit for hours on end is when a marginal part finally gives out.

Codes & Permits for AC Repair in Lebanon
In Lebanon, plumbing permits come from the Local Plumbing Inspector at the Lebanon Code Enforcement Office (Rod Furbush, Code Enforcement Officer) (15 Upper Guinea Road, Lebanon, ME 04027, (207) 457-6082 option 2). With 6,629 residents, Lebanon is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Lebanon has no confirmed public water or sewer system; plumbing work should assume private wells and septic systems townwide.
- Efficiency Maine offers rebates of up to $9,000 on qualifying heat pumps, but the equipment must be installed by an Efficiency Maine Residential Registered Vendor for the homeowner to receive the rebate. efficiencymaine.com
- Anyone who connects or disconnects gauges or adds/removes refrigerant on a heat pump or air conditioner must hold EPA Section 608 technician certification; the credential does not expire once earned. epa.gov
- The electrical circuit that feeds a new heat pump or AC condenser needs an electrical permit, issued by the Electricians' Examining Board or the town's own electrical inspector, before the wiring is installed or altered. maine.gov
How Aces Highlands Handles AC Repair in Lebanon
- Because roughly 67% of Lebanon homes are already on heating oil, a AC repair usually means deciding how much of the heating load the new equipment should carry, not ripping out what's there.
- Every outdoor unit we set gets its own permitted circuit before it's wired in, and any refrigerant work is done under our EPA Section 608 certification.
- Efficiency Maine rebates only pay out when a Residential Registered Vendor did the install, so we confirm eligibility with you up front — you can check any installer's registration yourself before signing anything.

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.

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.

Elijah and Highlands Heating & AC were super helpful! Boiler failed over the weekend and Elijah was very responsive and helpful, getting us up and running right away. I would recommend him at HH&AC highly!

AC Repair FAQs
How quickly can you repair my AC in Portland?
Outside of peak heat waves, most cooling repair calls are seen within a few days and often the same week. During a stretch of 90-degree days we prioritize homes with no working cooling at all. Call and tell us what the unit is doing — we will give you a realistic window, not a guess.
Do you repair mini-splits and heat pumps, or only central air?
All three. Most Southern Maine cooling is a ductless mini-split or a heat pump in cooling mode, and those make up the majority of our repair calls. We also service conventional central air condensers paired with a furnace and air handler.
My AC is low on refrigerant — can you just top it up?
A sealed system should never lose refrigerant, so a low charge means a leak. We can add refrigerant to get you through a heat wave, but we will tell you it is temporary. Finding and repairing the leak is the real fix and avoids paying for the same refrigerant every summer.
Should I repair or replace my air conditioner?
Repair a newer system with a single failed part. Replace when the unit is past 12–15 years, uses phased-out R-22 refrigerant, needs a compressor out of warranty, or has needed refrigerant more than one season. Efficiency Maine rebates on qualifying cold-climate heat pumps often tip the decision toward a new system that also heats.
Why does my breaker trip when the AC starts?
Usually a failing capacitor or a compressor drawing too much current on startup — both create a surge the breaker reads as a fault. It can also be a worn breaker or a shared circuit. Stop resetting it repeatedly; each trip stresses the compressor. We diagnose which it is on the first visit.
Do I need a permit for AC repair in Maine?
No. Repairs and part replacements on an existing system do not require a permit. Replacing the outdoor unit or installing a new system does involve electrical permitting and inspection, which we handle in-house as a licensed Maine electrical contractor.
