Getting the power into the house
Pairs with a $400-$850 interlock install for panel power; WGen models are transfer-switch ready with 30A and 50A outlets.
Service reality: No dealer network. Phone and email support plus authorized repair shops, and BBB records show that pipeline backing up, including shops dropping warranty work over unpaid claims.
Best for
The spec-driven buyer who wants 9,500 running watts of dual-fuel for about $1,249 and accepts DIY-grade support in exchange.
Not for
Anyone who expects warranty service to feel like Honda's dealer network; the support failure pattern is documented, not anecdotal.
What it does well
- +Most running watts per dollar in the dual-fuel class
- +Remote electric start and transfer-switch-ready outlets standard on WGen
- +Broad lineup from small dual-fuel units to 12,500-peak-watt machines
Where it falls short
Sourced, not our opinion. This is the part the brand's own page leaves off.
The FTC took action against brand licensee MWE Investments for warranty language that voided coverage when owners used independent parts or repair shops, and ordered the terms removed.

BBB complaints describe unanswered support tickets, four-month parts waits, unreimbursed authorized shops refusing further Westinghouse warranty work, and warranties not honored.
