Standby generator work makes up the largest part of our portfolio, and this page covers both halves of it: whole-home generators we installed from scratch, and machines other companies installed that customers later brought to us to look after. Sizes run from eight kilowatts on a dedicated essential-circuits switch up to twenty-two kilowatt units carrying an entire house through an outage.
What sets these projects apart is the load survey behind each one. Square footage alone does not size a generator — a well pump means no water at all when the power fails, a sump pump is the difference between a dry basement and a flooded one, and electric ovens or dryers draw several times what their gas equivalents do. The sizing on every install here was worked out from what that particular house actually has to run.
Many of these accounts also show years of annual generator service: oil and filters, plugs, battery, fuel plenum inspection and a load test that proves the transfer switch really hands over. Filter by town or year to browse the work. The standby generator services page covers sizing, installation and maintenance plans in detail.
