Alexis and Eric from Middletown, NJ have been Green Sun Energy Services clients since March of 2025. The Generac 7043 at the house is a 22 kW machine on a 100-amp transfer switch, installed in October of 2019. Green Sun took the maintenance over in March of 2025 and came back in March of 2026 – spark plugs and air filter, oil and filter, battery check and a load test on each visit. Taking on a machine somebody else installed is ordinary work: the first visit is where it gets gone over properly, and after that it is on the annual cycle like any other.

Standby generator questions from Middletown homeowners
Will a 22 kW generator run an entire Middletown house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
What fuel does a home standby generator use?
Most residential air-cooled standby generators are designed to run on either natural gas or vapour-withdrawn liquid propane. The generator and its fuel system have to be configured for whichever is chosen, and the required pressure, capacity and consumption figures depend on the model.
Can a standby generator be installed in Middletown without natural gas?
Yes. Residential standby generators commonly run on liquid propane. A properly sized tank, regulator and piping system has to be designed to deliver adequate vapour flow and pressure for the machine.
