  • Whole-house generators in Knoxville, TN are wired into your home's electrical system and designed to restore power seamlessly to your entire home in the event of a power outage. Whole-house generators start automatically when the power goes out, which keeps essential elements of your home running. These might include your refrigerator, air conditioning, heating, security system, telephone chargers, television, and lighting. In the event your power is out for an extended period of time, you maintain the conveniences you are accustomed to and protect your home and food supplies. The most common types of fuel used by a whole-house generator are diesel or natural/propane gas.
  • We install mostly 22kw, 24kw, and the new 26kw Generac systems. We also can install smaller portable units. The smaller unit we provide is a dual-fuel DuroMax 13000EH, which provides up to 50 amps of backup power.
  • A backup power generator protects your property from the effects of a power outage by providing temporary power for days after a disaster. Backup generators can keep important systems and appliances running in your home, including your sump pump to keep your home protected from flood damage.
  • Whole-house generators are wired directly into your home's electrical system and connect directly to the fuel source. If the power goes out, then these generators will turn on automatically. This means no trudging outside in terrible weather to restore power to their home.
  • We are a Generac-certified installer.
  • Generac power systems have a 5-year limited warranty for standby generators.
