"Jeremy is an incredibly efficient, kind, and hugely capable electrician. He spent the day at our house with his helpers installing a generator, and he dealt with every single problem that came up cheerfully and efficiently. I would highly recommend him to anyone for any size job. He makes himself available for any problems and is just overall a terrific person, who is extremely good at what does."

"Posted a job for a boiler replacement on homeadvisor on thursday and got a call in less than half an hour. Ron, one of the owners, said he could come take a look on saturday morning. I got a quote on monday. I decided to hire them on friday. Jeremy the boiler specialist and other co owner came by the the next day to take a few more pictures and check on a few other things. The boiler we decided on was a special order and took a few weeks to arrive. It came in on a monday and was installed by thursday. They started on thursday morning with a two man crew. Around lunch the Jeremy came by to see how things were going. Around 2pm an other two guys showed up to help. At about 3:30 the co owner and boiler specialist came by to oversee the final part of the install and operational testing. I was originally told it would be a two day install. They didn't just replace the boiler, they replaced the expansion tank, dual zone control box, etc. They worked until around 7pm to get it all done in one day. They bled all the radiators in the house and made sure they were heating properly. They took all the old parts with them and left no trash behind. Everybody from this company was extremely professional. They arrived within five minutes of the time they said they would be at my house. Nobody could beat the quote they gave me for the install. Any questions I had were responded to in 30 minutes or less. The install looks amazing so much shiny copper pipe. Cawiamca gave me a 3 year warranty where they will take care of all the labor and parts if anything goes wrong. This was by far the best experience I have ever had with a company coming to my house to do something.They performed consistently above my expectations. They will be the first people I call if I need any more work done on my heating system. I highly recommend Cawiamca."

"I hired Elevate Electric to install multiple electrical outlets in my basement after a waterproofing project. Kyle installed electrical outlets, ran a new circuit, and upgraded a breaker. The result looks outstanding! The new circuit wire is routed cleanly and he even dressed up some previous wiring too. Kyle shaped conduit around existing items along the basement wall making the whole utility room look good. This is probably the 4th time I have hired Kyle for electrical work. He consistently does great work. The quality is top notch and his pricing is extremely fair. You cannot go wrong with Elevate."

Generator Install questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.
