Honest installed ranges for whole-home standby systems in Greater Hartford — and the line items that move your number.
These are complete, permitted installed ranges for Greater Hartford, based on typical 2026 installer quotes. The unit itself is usually about half the installed cost — the rest is the transfer switch, pad, gas line, electrical work, permits, and inspection.
| System | Typical installed range | Best for |
|---|---|---|
| 14–18 kW air-cooled standby | $11,000–$16,000 | Essentials in a 1,500–2,500 sq ft home |
| 20–26 kW air-cooled standby | $14,000–$22,000 | Larger homes, central air, broader coverage |
| 30 kW+ liquid-cooled standby | $22,000–$35,000+ | Big or all-electric homes, outbuildings |
| Automatic transfer switch (whole-house) | $1,500–$3,500 | Included in most installed quotes above |
| Managed-load transfer switch | $1,200–$2,500 | 100-amp panels, load-shedding setups |
| Gas line, pad & trenching | $1,000–$3,000 | Varies with distance from the meter |
| Propane tank (500 gal, above-ground) | $1,500–$3,000 | Homes without natural gas service |
A legitimate written estimate itemizes the unit, transfer switch, pad, gas work, electrical work, permits, and inspection — and states what is not included (landscaping restoration, panel upgrades, meter upgrades). If a quote is a single lump sum with no breakdown, ask for the breakdown before comparing it to anyone else's.
Portable generators have a place — job sites, camping, a short outage — but they are not whole-home backup. Running extension cords through a cracked window, refueling in a storm, and manually managing loads is a different product from an automatic standby system, and this site steers toward standby for homeowners who want the house to just stay on.
Yes, in nearly every town: an electrical permit and a gas permit, plus a final inspection. Your installer should pull both.
One to three days of on-site work once permits are in hand, plus scheduling lead time — which stretches after major storms.
Either. Natural gas where service is available; propane where it isn't. Most residential standby units can be configured for either fuel at install.
