"I have no complaints about Mr. Electric. In fact, the technician went above and beyond and was excellent. He couldn't make it on the day of installation, which was unexpected, but his stand in honored his commitments. The only reason to not give 5 stars was that it seemed excessively expensive. I wouldn't pay that again for what it was. I'd do it myself. Even Angi gave me a reasonable quote. They charge six times that reasonable quote for a simple outlet transfer... 10/10 for customer service. I guess you'd have to be though, for all that money."

"I needed assorted areas addressed due to a building assessment review before a sale. It was wonderful to work with someone who gave a fast and honest appraisal of the work that needed to be done. There was an outlet that was flagged as not working, but that was found to be lightswitch. There was a broken light fixture, replaced quickly. A loose outlet box tightened. The list was significant, but handled quickly and professionally. Charged 1.75 hours plus materials. HIGHLY recommended."

Generator Install questions, answered by experts

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.
