“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.”
Residential heating, every system, every season.
Furnace, boiler, heat pump - all of them, all across Trumbull, Mahoning, Portage, Ashtabula, and Columbiana counties. NATE-certified techs, ACCA Manual J on every install, 24/7 emergency no-heat dispatch.

Heating matters more in NE Ohio than AC does.
Northeast Ohio is a heating-dominated climate - roughly 6,000+ heating degree days against 700 cooling degree days. The 99% ASHRAE heating design temperature for the Warren / Youngstown / Cleveland area is around 5F, with cold snaps that push below that several times a season. Your furnace, boiler, or heat pump runs eight to nine months out of the year. When it quits in February, it isn't an inconvenience - it's a frozen-pipe emergency.
We service every common system in the Valley. Old cast iron Burnham or Weil-McLain boilers heating 1940s Warren or Youngstown homes - still serviceable, often for another decade. Standard 80% AFUE gas furnaces in mid-century ranches. High-efficiency 95-97% AFUE condensing furnaces in newer Howland, Canfield, and Boardman builds. Cold-climate inverter heat pumps and dual-fuel hybrids for homeowners who want the lowest lifetime heating cost at NE Ohio gas and electric rates.
Common-failure parts ride on the truck - hot-surface ignitors, flame sensors, draft inducers, control boards, gas valves, ECM blower modules - so most no-heat calls finish in one visit. New installs follow ACCA Manual J load calculations sized to the 5F design temp. No eyeballing, no "match what was there," no upsell to a system bigger than your home needs.

What NE Ohio says about AK Heating & Cooling
“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.”
Get the tune-up before the first cold snap
Book your annual furnace tune-up in September or early October, before the first real cold snap. A clean flame sensor, a fresh ignitor check, and a combustion analysis catches the small issues while they're still small - and well before our dispatch board fills up with no-heat emergency calls. Flame sensor cleaning alone extends furnace life by years.
