Generator Installation in Idaho Falls, ID
Idaho Falls generator installers in this directory cover central Idaho Falls, Ammon, Iona, and the surrounding Bonneville County. Idaho Falls's harsh winters (-15°F design temps), wind exposure, and rural acreage density drive consistent generator demand. A 22-26 kW air-cooled Generac, Kohler, or Cummins running on natural gas or propane runs $12,500-$17,500 installed including the cold-weather kit, ATS, and concrete pad.
Idaho Falls Power covers most city service; Rocky Mountain Power covers outlying areas. Most rural Bonneville County homes run on propane (500-1,000 gallon tanks). Cold-weather kits — battery warmer, oil-pan heater, block heater, synthetic 5W-30 oil — are essential for reliable -20°F starts.
Frequently Asked Questions
- Will a generator start at -20°F in Idaho Falls?
- Only with a properly specified cold-weather kit — oil-pan heater, battery warmer, block heater on liquid-cooled units, and synthetic 5W-30 oil. Without these, batteries and oil systems fail in extreme cold. Test starts monthly through winter.
- How big a propane tank do I need for an Idaho Falls home?
- For a 22 kW unit at 50% load running through a multi-day winter outage, plan for 500-1,000 gallon tank capacity (3-7 days runtime). Larger acreages with electric heat pumps or in-floor radiant often need 1,000-1,500 gallon banks.
- Should I do natural gas or propane?
- Natural gas if Idaho Falls Power gas service reaches your property — no tank refills, virtually unlimited runtime. Propane is the practical default for outlying acreages. Tank lease through a propane provider runs $80-$150/year if you don't want to own.
