Whole-House Generator Installation
Backup power that keeps Grand Rapids homes running through West Michigan outages. Real Pro-Tech installed pricing from $11,500 to $17,000 — propane or natural gas.
Whole-house generator cost in Grand Rapids.
Pro-Tech Heating & Cooling sizes every standby install to your real electrical load — HVAC, refrigerator, sump pump, well pump, and whichever comfort circuits matter most — then locks in one fixed installed price. No surprise upcharges after the technician walks the house.
Every Pro-Tech generator install includes the automatic transfer switch, the factory-recommended pad, the gas-line connection at the meter, and the municipal electrical permit and inspection. Longer gas runs, panel upgrades, and unusual site work are quoted transparently after the in-home evaluation.
| Output | Backs up | Fuel | Installed | Monthly |
|---|---|---|---|---|
| 7–10 kW | Essentials: furnace, fridge, sump pump, well pump, some lights. | Propane / Natural Gas | $11,500 | from $125/mo |
| 12–15 kW | Small-to-mid home: essentials + one AC or heat pump condenser. | Propane / Natural Gas | $13,500 | from $146/mo |
| 16–20 kW | Most West Michigan homes: essentials + full HVAC + water heater. | Propane / Natural Gas | $15,000 | from $163/mo |
| 22–26 kW | Larger or all-electric homes; two HVAC systems; hot tub or EV loads. | Propane / Natural Gas | $17,000 | from $185/mo |
Final numbers are confirmed after an in-home evaluation of gas-line access, pad location, panel condition, and municipal permit requirements.
Four things that move the price.
Every install is scoped to your actual home, so the same kW tier can land differently from house to house.
Home size & essential loads
Furnace + fridge + sump/well pump + a few lights land in the 7–10 kW range. Add an AC condenser or two, a heat pump, or an electric water heater and you move up to 12–15 or 16–20 kW.
How much of the house stays on
Backing up only critical circuits keeps the generator smaller; whole-home coverage — HVAC, kitchen, laundry, EV charging — needs the larger 22–26 kW tier, especially in all-electric homes.
Fuel source availability
Grand Rapids gas mains make natural gas the easy default when a service line already runs to the home. Propane is common on rural West Michigan properties and prices identically at every kW tier in our pricing sheet.
Installation site conditions
Pad location, gas-line run distance, electrical panel work, and permit/inspection requirements in your municipality (GR, Kentwood, Wyoming, Grandville) all factor into the final proposal.
