Answers to Common Questions
View All FAQsWhat are the top reasons a Generac generator won't start?
The top reasons a Generac won’t start are low or stale fuel, a weak battery, overdue oil service, or storm-related damage. In Boise and Meridian, our technicians see these most often during outage season. Schedule an annual professional inspection to catch issues early.
- Verify fuel level and quality.
- Check battery charge and connections.

Change the oil in your standby generator every six months or after 100 hours of use, whichever comes first. Also schedule a professional inspection once a year. Do a simple monthly self-check to verify fuel level, battery health, and overall condition.

Installing a home standby generator is a customized project, so final cost is confirmed after an on-site assessment by Diamond Heating, Cooling, Plumbing & Electric. The biggest driver is generator size (kilowatts), because larger units demand more electrical capacity and fuel supply. Total price also depends on equipment choices and installation complexity at your home; professional installation protects warranties and ensures code compliance. We install many systems across the Boise–Treasure Valley region and present clear, itemized proposals. A right-sized unit often costs less overall than an oversized model that forces extra electrical or gas work. Seasonal offers may include $100 off Generac yearly maintenance or a free whole-home safety inspection with a new generator install; ask about current availability.
Key items that influence your quote:
- Required wattage to cover essentials versus whole-home
- Fuel source and any line work (natural gas, propane, tank location)
- Transfer switch type and load management strategy
- Site work and permitting (concrete pad, trenching, distance to meter/panel)
Schedule a professional sizing visit to receive a firm, written quote for your home. <br/> Updated: 2026-03-11 <br/> Need help in Star, ID? Call (208) 378-6624 or book online.
