Power That Doesn't Quit
Why Homeowners Invest in a Backup Generator
A power outage that lasts more than a few hours tends to be when homeowners start thinking seriously about generator installation and repair. Davis Heating, Cooling, Plumbing & Electric handles the work for homeowners throughout Danville and Roanoke who want reliable backup power, whether that’s a new system or keeping an existing one running.
A backup generator installation isn’t a one-size-fits-all decision. The right size depends on what you want covered during an outage, from just the essentials to the entire home, and that choice affects both the equipment and the electrical work involved. Working with an experienced electrical company helps ensure the generator is properly sized, safely connected to your home’s electrical system, and installed to meet applicable electrical codes.
What's Included
Generator Installation
Whole-house generator installation starts with sizing the unit correctly for your home’s electrical load and the circuits you want covered during an outage. Davis Heating calculates that load based on your specific home, not a generic estimate.
Installation includes setting the generator on an appropriate pad or mount, wiring it into your electrical system through a transfer switch, and connecting the fuel source, whether that’s natural gas, propane, or another option depending on what’s available at your property.
Ask our team about current offers on generator installation, or book your appointment to find out what’s available.
Keeping Your Generator Running
Generator Repair
A generator that won’t start, doesn’t transfer power automatically, or runs rough is usually dealing with a specific, diagnosable issue rather than a sign it needs full replacement. Davis Heating identifies the actual cause before recommending a fix.
Generator service and repair covers the range of issues that come up over a unit’s lifespan, from battery and starter problems to fuel system issues and transfer switch failures. Routine maintenance also catches many of these problems before they turn into a no-start situation during an actual outage.

What Danville & Roanoke Homeowners Are Saying
From Homeowners We've Worked With
A generator only matters when the power actually goes out, so it needs to work the first time, every time. Read what Danville and Roanoke homeowners have shared about their experiences with our generator team.
More Than Backup Power
Other Electrical Services We Handle
A generator ties into the same electrical system running through the rest of the house, which is why the panel and wiring behind it matter just as much. Davis Heating handles all of it, from repairs and new installations to the lighting and EV charger work listed below.
Sizing a Backup System
How Home Generator Installation Is Sized
A generator sized correctly for a home covers the circuits you actually want running during an outage without drawing more fuel or costing more than necessary. Some homeowners want everything covered, while others just want the essentials like refrigeration, heat, and a few key outlets.
Generator installation services should start with a conversation about what matters most to you during an outage, since that directly shapes equipment size and where the transfer switch and circuits get wired.
Fuel Source Options
Choosing a Fuel Source for Your Generator
Natural gas offers a continuous fuel supply as long as utility service to the home remains active, which makes it a common choice where it’s available. Propane works well as an alternative in areas without natural gas access, though it requires an on-site tank that needs periodic refilling.
Backup generator installation in a home with an existing gas line is often simpler than starting from scratch, since some of the infrastructure is already in place. Homes without gas service typically go with propane or, less commonly, diesel for larger installations.
Common Repair Issues
What Typically Causes Generator Repair Needs
Battery failure is one of the most common reasons a generator won’t start when it’s needed, since batteries degrade over time even if the unit itself is fine. Fuel system issues and worn starter components round out the more frequent causes of generator repair calls, along with transfer switches that fail to engage automatically. Regular maintenance catches most of these before they become a problem during an actual outage.

Common Questions
Generator Installation and Repair FAQs
Homeowners in Danville and Roanoke ask these questions most often about backup generators. If yours isn’t covered here, reach out and we’ll walk you through it.
What size generator do I need for my home?
It depends on what you want covered during an outage, from just essentials to the whole house. We calculate the right size based on your specific electrical load.
How long does whole home generator installation take?
Most installations take one to two days, depending on the equipment size and how far the unit is from the electrical panel and fuel source.
Does my generator need regular maintenance?
Yes, routine maintenance keeps a generator ready to start when it’s actually needed, and it catches many issues before they cause a failure during an outage.
Can you repair a generator that another company installed?
Yes, we work on generators regardless of who originally installed them.
What's the difference between a portable and a whole-house generator?
A portable generator requires manual setup during an outage, while a whole-house system starts automatically and can cover significantly more of the home’s electrical load.
