AC Repair for Kittery Homeowners

Kittery 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.

- Diagnostics come first, upsells do not — the invoice matches the quote

Kittery Homes and What They Need
Kittery has the oldest housing stock of the York County coastal towns Aces serves, with a median build year of 1965 and about 25 percent of homes predating 1940 (46 percent predating 1960) -- fitting for a town that has been incorporated since 1647. On homes this old, a rewiring project often turns up several generations of electrical work layered on top of each other.
Heating and Cooling in Kittery
Fuel oil heats about 60 percent of Kittery households, the highest share of any York County town Aces studied, with bottled or tank propane at 18 percent and electricity at 13 percent; Unitil also supplies natural gas to parts of town. That heavy oil dependence makes Kittery a strong market for pairing existing systems with a heat pump.

Getting to Know Kittery
Kittery was incorporated in 1647, making it the oldest incorporated town in Maine, and sits as the state's southernmost town, across the Piscataqua River from Portsmouth, New Hampshire. The Portsmouth Naval Shipyard, established in 1800 on Kittery's Seavey's Island, was the U.S. Navy's very first federal navy yard.
During the Revolutionary War, some of the first vessels ever built for the U.S. Navy, including the USS Ranger under John Paul Jones, were constructed right on Kittery's Badger's Island -- a history that still shapes the town's identity along the water.
Local & Independent — Not a Franchise
Aces Highlands answers to Kittery homeowners directly, not a franchise office somewhere else in the country. Technicians are not on commission, so the recommendation you get is the one your house actually needs. Earning the next call, not hitting a sales target, is the entire business plan.
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.

- 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
- 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
How Aces Highlands Handles AC Repair in Kittery
- Because roughly 60% of Kittery 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.
- We flag which Efficiency Maine incentives apply to a AC repair before work starts, since the rebate only applies through a Residential Registered Vendor.

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!

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.

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.
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.
