Generator Maintenance in Denver
A generator that sits unused for eleven months and then gets asked to carry the whole house through a three-day blizzard is a generator that finds its weaknesses at the worst possible time. Denver's weather events don't give much notice. The Front Range snowstorms that develop fast, the ice storms that knock out power in Cap Hill and Washington Park for days, and the severe thunderstorms that move through the metro in summer don't schedule around when it's convenient to discover that a generator hasn't been serviced in two years.
Generator maintenance is what closes the gap between a unit that's technically present and one that's actually ready. A generator tune-up covers the components that degrade during storage and inactivity as much as the ones that wear through use. Oil gets changed on the manufacturer's schedule regardless of hours run. The fuel system gets checked for stale fuel, varnish buildup in the carburetor, and filter condition. The battery gets load-tested, not just checked for voltage, because a battery that reads acceptable on a basic check can still fail to start an engine under real conditions. Spark plugs, air filter, coolant level on liquid-cooled units, and the cooling system on air-cooled units all get checked and addressed.
Generator inspection during a maintenance visit also covers the less obvious items. We check the transfer switch operation, the automatic start sequence on standby units, the voltage and frequency output under load, and the integrity of the connections between the generator, the transfer switch, and the home's electrical system. A generator that starts and runs doesn't tell you everything about whether the full system is going to perform correctly when it's actually needed.
Denver's high altitude affects carburetion on air-cooled generators. A unit tuned at sea level runs slightly rich at 5,280 feet, which affects fuel consumption and can accelerate carbon buildup over time. We account for altitude when servicing generators in the Denver metro.
Generator service cost for a standard maintenance visit is straightforward. We give you the number upfront and don't add items without telling you first.
