Frequently Asked Questions


A generator can have an electrical problem even when the engine appears to be operating normally. We can inspect the system for a faulty voltage regulator, damaged wiring, or a tripped circuit breaker. Once we identify the problem, we can restore the backup power your home needs.

Most home generators should be serviced at least once a year. However, the service schedule depends on the manufacturer’s recommendations, generator type, operating conditions, and how often you use it. Regular inspections can catch problems early, so we can repair them and ensure your generator works when you need it.

A generator that starts but repeatedly shuts down may have a mechanical, electrical, or fuel-related problem. Some shutdowns happen because a safety feature protects the equipment. We can diagnose the underlying cause and make the right repairs so your generator runs reliably.

Whether to repair or replace your generator depends on several factors, including its age, condition, and repair history. An older generator may become harder or more expensive to maintain, especially when key components are no longer readily available. However, age alone doesn’t mean you must replace your generator. We can evaluate your generator and compare the estimated repair costs with the benefits of installing a new system.

McAllister has done work for us multiple times, and we always receive excellent service. We have an old gas boiler heating system and had a pipe burst. Needless to say, we were anxious about it. Jeff came out, diagnosed, and fixed the problem on very short notice. Professional service at a reasonable price. What a huge…

McAllister just recently installed all new heating and cooling systems in our home and rental property. From the first interaction with the sales rep to the men that did the installation, everyone was professional, kind, and very easy to work with. We have had many updates and things done to our home recently, and I never…

Simply the best! We have used McAllister since we moved six years ago, and they have always been professional, responsive, and accommodating. Quality costs, but you get what you pay for. And it's worth it to us when, at 8pm on a Friday night, a professional will come out and do their best to get our…

I was away from my home from 8:00 am until 10:00 pm. When I got home, I heard water running. The pipe under my sink burst and flooded my bathroom, hallway, and basement. I called McAllister as I know they have an emergency number. A very nice gentleman was at my home within the hour. He…

My hot water heater exhaust chimney was blocked. The gas company showed me the carbon monoxide reading and shut it down. The guys from McAllister showed up promptly, figured out the problem without much fuss, fixed that hot water heater, AND another hot water heater that had been shut down long ago, probably for the same…
