Generally, it’s really hard to find techs and tech companies that do not try to make up the problem, or overcharge you. But these guys were really honest and the problem was solved. Will definitely use their services again.

Signs Your Generator Needs Professional Repair

A generator that fails when you need it most defeats the entire purpose of having one. Catching issues early through regular servicing and prompt attention to warning signs keeps your system ready for the next Raleigh storm.

  • Won’t start during an outage
  • Starts but delivers reduced power
  • Unusual noises during operation
  • Visible corrosion or fuel leaks
  • Error codes or warning indicator lights
  • Not serviced in the past year

If your generator is showing any of these signs, don’t wait for the next outage to find out how serious the problem is. Tech-On-Deck’s certified technicians can diagnose the issue and get your backup power system back to full operating condition.

Frequently Asked Questions About Generator Installation and Repair

How Large of a Generator Does My Raleigh Home Need?

Generator sizing depends on which circuits you need to power and your home’s total electrical load. Most single-family homes are well served by a 20 to 22 kilowatt standby generator, but the right answer depends on your specific setup. Our technicians determine the correct capacity during the site assessment.

Most whole house generator installations are completed in one to two days. The exact timeline depends on site prep, the fuel line connection, and the electrical panel work involved. We give you a clear schedule upfront so you can plan accordingly.

Most whole house standby generators run on natural gas or propane. If your home has a natural gas line, the generator connects directly to it. Homes without natural gas can use a propane tank. We help you determine the best fuel source during the site assessment.

Standby generators should be professionally serviced once a year. Most units also run a brief self-diagnostic test cycle weekly. Annual maintenance covers oil changes, filter replacement, spark plug inspection, and system testing to keep the unit ready for real-world use.

An automatic transfer switch monitors utility power and switches your home to generator power within seconds of an outage, then switches back when utility power is restored. It’s a required component for whole house standby installations and is included in every Tech-On-Deck generator project.
