Reliable Backup Power, Ready When You Need It

Unpredictable weather, grid failures, and service interruptions can leave your home powerless in an instant. Jim Needham Heating, Cooling, Plumbing, Drain & Electrical provides dependable solutions that ensure your lights stay on, your appliances keep running, and your family remains safe and comfortable. Our team installs and services complete backup systems designed to meet the demands of modern living—quietly, efficiently, and with lasting performance.

Home Generator Installation – We help you select the right unit for your layout, energy usage, and specific backup needs. From fuel connection to electrical integration, every part of the setup is handled with expert precision.
Ongoing Maintenance – Preventative service keeps your system ready at a moment’s notice. Our tune-ups include battery checks, fluid changes, filter replacements, and load testing to catch issues before they escalate.
Fast Repair Services – If your backup power isn’t performing as it should, we quickly identify and fix the problem—whether it’s a startup issue, output drop, or mechanical fault.
Transfer Switch Installation – We install seamless transition equipment that automatically or manually shifts your home to backup power when the main supply fails. These switches prevent safety hazards and reduce downtime during an outage.

A dependable power supply can’t wait until there’s an emergency. That’s why we make it easy to choose, maintain, and service the equipment your home depends on when the unexpected hits.

How often should my backup power system be serviced?

Most manufacturers recommend a full inspection and tune-up at least once a year. Regular maintenance keeps the system primed for emergency use and helps avoid costly repairs down the line. If your unit runs frequently or sits idle for long periods, we may suggest more frequent checks.

What’s the difference between a portable unit and a permanent installation?

Portable systems offer short-term power for a few devices but require manual setup and fuel storage. Permanent models are hardwired into your home, activate automatically, and supply much more consistent power. For long outages or whole-home support, a permanent setup offers more convenience, safety, and coverage.

Can I power my entire house or just certain areas?

That depends on the size of the backup unit and how it’s configured. Some systems are designed to run just essential circuits—like the fridge, HVAC, and a few outlets—while others can handle your whole home. We’ll help you determine the best fit based on your priorities and energy usage.
