Unlike generator-only dealers, AK handles your HVAC, refrigeration, and standby power on one work order — and unlike HVAC-only shops, we're a Generac authorized dealer with stocked parts and factory-trained technicians.
A Generac home standby kicks on within seconds of an outage and runs your whole house on natural gas or propane — refrigerator, furnace, sump pump, internet, the works. AK Heating & Cooling is a Generac authorized dealer: we size, install, permit, activate, and maintain every system we sell across Trumbull, Mahoning, Portage, Ashtabula, and Columbiana counties.
Restaurants that can't lose the walk-in. Multi-tenant buildings on a Trumbull or Mahoning County grid. Light industrial running CNC equipment overnight. AK installs Generac commercial standby systems with the load profile and switchover scheme your operation actually needs — and we handle the permits and AHJ coordination start to finish.
Picking the right generator size is the difference between a system that does what you need and one that's underwhelming the day you actually need it. AK walks every customer through a real load profile — what stays on during an outage, how it pairs with your fuel source, and what the install actually costs. No pressure, no upsell.
A standby generator only matters if it starts and runs under load when you actually need it. Annual Generac maintenance includes oil, filter, spark plugs, battery, controls verification, and a load test — all required to preserve your manufacturer warranty. Between visits, we're on a 24/7 service line.
Run your standby under load for 30 minutes once a month. Sitting idle is what kills a generator — the goal is to keep the oil moving and the battery topped up so it kicks on the day you actually need it.
Three Alex Mantalis companies, one Warren HQ. Each with its own license and insurance — coordinated when you need more than one trade.
