Annual Generac maintenance.

Two reasons. First, the Generac 5-year limited residential warranty requires documented annual maintenance from a qualified servicer - skip a year and warranty claims can be denied. Second, the whole reason you bought a standby is that it actually runs when the grid drops. A unit sitting idle 350+ days a year develops dead batteries, gummed-up carburetors (on older units), stale oil, and corroded contacts. Annual maintenance is the only way to know it'll start under load on the day you need it.

Engine oil and oil filter change (synthetic 5W-30 typical), air filter inspection or replacement, spark plug inspection or replacement, battery load test and clean terminals, valve adjustment as needed per service hours, fuel system inspection, coolant level check (and replacement on 2-year cycle for liquid-cooled), full operational test including transfer-switch cycle, controls programming verification, and a load test under real conditions. We document everything for Generac warranty records.

Fall (September through October) is ideal - gets the unit ready for winter storm season when NE Ohio sees its worst multi-day outages from ice and lake-effect snow. Spring (April through May) also works if you want it ready for summer storm season and heat-wave demand. Avoid scheduling in deep winter or peak summer when our trucks are running emergency calls.

Some of it, yes - checking the battery, changing oil, clearing debris from the air intake. But Generac warranty documents require service from a qualified servicer on the major intervals, and electrical work near the transfer switch falls under licensed electrical work in Ohio. The bigger issue is oil disposal regulations (used oil from a stationary engine isn't household waste) and the load test, which requires equipment most homeowners don't have. Most homeowners do basic monthly checks themselves and bring AKHC in annually.

Call (330) 469-6701 for current plan rates. Costs depend on unit size, location, and whether you're on a single-visit basis or a multi-year contract. Commercial liquid-cooled and paralleled systems run more than residential air-cooled. We offer single-visit pricing and 3-year or 5-year contracts that lock in the rate and waive after-hours premium if you call for emergency service mid-year.

Every 3 to 5 years, regardless of maintenance schedule. Battery is the number-one cause of standby generators failing to start during an outage - it sits at low draw for years and slowly loses capacity. We load-test the battery on every visit and flag it for replacement when capacity drops below threshold. AKHC stocks Generac OEM batteries on the truck.

Air-cooled Generac engines need valve adjustment at specific service intervals - typical first valve adjustment around 200 hours of runtime, then on a hour-based schedule after. Skip it and you'll start losing compression, see harder cold-starts, and eventually crack a valve or burn an exhaust seat. We track service hours on every unit we maintain and schedule the valve adjustment when it's due.
