Math, not eyeball
Manual J on every install. We will not size a system by matching what was there - that's how you get a system that short-cycles, can't dehumidify, and dies in eight years instead of fifteen.
Residential / Air Conditioning
AC installation done by the math, not by the eyeball.
ACCA Manual J load calculations, AHRI-matched indoor and outdoor components, written warranty in your hand before you sign. Carrier, Trane, Lennox, Goodman, Daikin, Rheem - the brand that fits your home, not the brand we get the best margin on.
The biggest install mistake is the wrong size.
Walk through any Northeast Ohio neighborhood in July and half the AC units running are the wrong size. Most were sized by matching what was there, or by upsizing "to be safe." Both moves are wrong - oversized AC short-cycles, runs sensible cooling only, and leaves the house cool but clammy. Undersized AC runs nonstop, never hits the setpoint on a 90-degree day, and burns out the compressor in half the rated life.
We run ACCA Manual J on every install. Your home's square footage, ceiling heights, insulation R-values, window count and orientation, infiltration rate, and the local design conditions (88°F cooling, ~50% RH summer humidity, IECC Zone 5A) all feed into a heat-gain calculation that produces the right tonnage. Then Manual S picks the equipment that actually delivers that capacity at our design conditions, not on a marketing brochure. Then Manual D verifies your existing ductwork can move the air.
The result is a system that runs the right cycle length, pulls indoor humidity down to 45-55%, hits the warranty's full life, and qualifies for every rebate and tax credit it can.

- Old equipment haul-away and recycle/disposal
- Permit pulled in your name, inspection scheduled and met
- Electrical disconnect upgrade if existing doesn't meet code
- Concrete or composite pad for outdoor unit, leveled and set above snow line
- Condensate drain pan, float switch, and code-compliant drain routing

- Walk-through with you on operation, filter location, thermostat setup, and what to expect first season
How it works
How an AKHC visit works.
Six steps from the first call to a working system. No surprise charges, no "change orders" mid-install.
- 1
In-home assessment
A real tech (not a salesperson on commission) walks the home, runs Manual J on the spot or back at the office, and gathers what we need: panel capacity, line-set condition, ductwork sizing, drain routing, outdoor unit clearance.
- 2
Written quote with options
You get a written quote with three honest tiers - base, better, best - matched to your Manual J load. AHRI match number listed for each. Refrigerant type listed. Warranty terms listed. Tax-credit eligibility flagged where applicable.
- 3
Schedule + permit
We pull the mechanical permit in your name, lock the install date, and order the equipment. Common installs ship in 3-7 business days; specialty equipment 1-2 weeks.
- 4
Install day
Two-tech crew typical, single-day install for most replacements. Recover old refrigerant, remove old equipment, set new pad, install indoor and outdoor units, evacuate and charge the line set, wire and commission.
- 5
Startup + verification
We verify refrigerant charge by weight, measure superheat and subcool, test airflow at the registers, check the condensate drain, and walk you through operation. Nothing leaves the install until it's right.
- 6
Inspection + warranty
Local building inspector signs off. We register the manufacturer warranty within the eligibility window so you keep the full 10-year parts coverage. You get all docs by email.
Why pick AKHC
Why homeowners pick AKHC.
Plenty of NE Ohio shops can drop in a unit. Here's what makes an install with us different.
AHRI-matched, warranty-valid
Every indoor coil + outdoor condenser pair is AHRI-matched - required for warranty validity and rebate eligibility. We register the warranty on your behalf inside the manufacturer's window so you don't lose the full 10 years.
Honest brand recommendations
Carrier, Bryant, Trane, American Standard, Lennox, Goodman, Amana, Daikin, Rheem, Ruud - we service all of them and install the major ones. We recommend the brand that fits your budget and home, not the brand with the best installer kickback.
Lake-effect and salt-belt aware
Outdoor units in the heavy-snow corridor (Ashtabula, eastern Trumbull) get set 24" elevated on a stand, not the standard 12". Units near salted streets get coil-coating options. We've seen what NE Ohio winters and roadway salt do to bare aluminum fins.
Permit-in-your-name
We pull the mechanical permit in your name and meet the inspector. Some shops skip permits to save fee dollars - that voids manufacturer warranties and creates problems at home-sale inspection. We never skip.
Tax credit + rebate filing help
If your system qualifies for the 25C tax credit or a current Ohio utility rebate, we provide the AHRI match number, model numbers, and ENERGY STAR certification docs you'll need at filing time. We can't file your taxes for you but we make sure you have what you need.
FAQ
Frequently asked.
Why do you require a Manual J load calculation?
Most shops match the size of the old unit or upsize "to be safe." That's how Northeast Ohio ends up with oversized AC systems that short-cycle, can't pull humidity, and burn out compressors early. ACCA Manual J does the actual math on your home: square footage, insulation R-values, windows, orientation, infiltration, and design temps. Right-sized equipment runs longer cycles, removes more humidity, and lasts longer.
What does AHRI-matched mean and does it matter?
AHRI (Air-Conditioning, Heating, and Refrigeration Institute) tests indoor coil + outdoor condenser combinations and publishes performance ratings only for matched pairs. Using an AHRI-matched system is required for the manufacturer's warranty to be valid and for federal tax credits and utility rebates. A "close enough" mismatch from a discount installer voids the warranty and the rebate eligibility.
What refrigerant will my new system use?
Equipment manufactured after January 1, 2025 ships with either R-32 or R-454B - both A2L refrigerants with lower global warming potential than the R-410A they replaced. Pre-2025 equipment in installer inventory still uses R-410A and can still be installed legally. We'll tell you exactly which refrigerant your system will use before you sign.
Am I eligible for the federal tax credit?
The 25C Energy Efficient Home Improvement Credit historically offered up to $600 for central AC (the equipment needs to meet SEER2 16+ and EER2 11.7+ in the northern climate region, plus ENERGY STAR certification). Heat pump installs are eligible for a much larger credit - up to $2,000. Tax law changes affect availability; verify current eligibility with your tax preparer or at irs.gov before counting on a specific dollar amount.
How long does an installation take?
Most residential AC replacements are a single-day install - 6 to 8 hours from arrival to system test. New construction or first-time AC installs that require new line sets, electrical, or ductwork can run 1.5 to 2 days. We give you a realistic window in the written quote before you sign.
Do I need a permit?
Yes, in nearly all Northeast Ohio jurisdictions. Equipment replacement and any electrical or refrigerant-line work require a mechanical permit pulled by the licensed contractor. We pull the permit, schedule the inspection, and meet the inspector on-site. The fee is rolled into your quote so there are no surprises.
What's the warranty on a new install?
Most major manufacturers offer 10-year parts on residential AC and heat pump equipment when you register the install within 60-90 days of startup (we handle the registration). Some brands extend labor to 5-10 years on registered installs. Compressor coverage is sometimes longer. We give you the exact warranty terms in writing before you buy.

What NE Ohio says about AK Heating & Cooling
4.9 avg· 72+ reviews
“Furnace went out on a Sunday night. AK had a tech in the driveway in 90 minutes, parts on the truck, and we were warm before kids' bedtime. Worth every dollar of the maintenance plan.”
“Our restaurant walk-in went down at 6am. AK answered the after-hours line on the second ring and had us running before lunch service. We've switched all of our refrigeration work to them.”
“Had Generac install, AC tune-up, and a humidifier swap done across two visits. One bill, one company, real techs. This is what local service is supposed to feel like.”
Clark's Tip · Lowering Energy Bills
Bigger is not better
If a contractor pitches you a system one size larger than your old one "so it doesn't have to work as hard," walk. Oversized AC short-cycles - it cools the air fast but never runs long enough to pull the humidity. You end up cool and clammy, the compressor wears out years early, and your bills go up. Right-sized equipment running long, steady cycles is the goal.
