Recommended size for Oak Ridge
| Oak Ridge Home Profile | Recommended Size |
|---|---|
| Typical home — ~2,500 sq ft, gas appliances, 3–4 ton central AC | 22kW |
22kW is the right call for most Oak Ridge homes — a 2,500 sq ft house with gas appliances and a 3–4 ton central AC needs more load headroom than a 14kW unit can reliably hold during a summer outage.
Want the full sizing math — why 14kW runs out of headroom and where 22kW gets its margin? See the complete generator sizing guide.
