Recommended size for Farragut
| Farragut 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 Farragut 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.
