"This project was the complete remodel of a split entry, three-bedroom house (in various states of disrepair). I was given a thorough estimate, and we reviewed the work scope in great detail. Even when confronted with some unexpected issues (items that were not obvious until we begin the demo) midstream, they gave me complete Information so that I could make an informed decision on how to proceed. Their work is excellent, they are reliable and easy to communicate with, they are proud of what they do and want you to be happy with the results. My project included general construction, electrical, plumbing, and mechanical assessment. I highly recommend Powerhouse and will continue to use them for my general contracting needs. As I recently told them, **you are my guys from now on!** Thank you, Clayton, JD, and Chris for a job well done!"

"Brian installed a dedicated circuit in our basement. Brian answered the first time I called. He set up a time to come and review the job. On the day he came, he called to make sure I was at home. He gave me a reasonable price for the job and agreed to do the work the following week. He came exactly when he said he would and performed the work in the time frame he specified. I am extremely pleased with Brian's work and would highly recommend him to anyone who is in need of electrical work."

"I hired Jason to install a simple ceiling trim as well as to install a new lighting fixture on a 20-foot ceiling. What I really liked about Jason is that he executed the work and did not cause any damage elsewhere. He built scaffolding, which is heavy, to install the light on my relatively new Maple floors and there was not a scratch. My consistent problem with most contractors is that although they can usually do the work, they cause things like floor scratches or marks or dents in the walls... there is usually some residual damage to having a project done. Jason executed the scope of work without a single additional flaw. His price was also reasonable overall. At one point I asked him to also install a new outlet to support the new Chandelier. He did it without hesitation or an upcharge. I know most contractors would have charged an additional 15 or $20 for that. I would hire him again"

"We loved going with express essential services. The receptionist was very nice and was up front and honest about what there policies were. She gave me a day and time for an evaluation (they had a technician there exactly when she said). Our technician was great he quickly diagnosed our problem and got in touch with the company. Before he had even left the receptionist was calling me back with the price to fix it and a few available dates. We got a date booked to do the work I sent the deposit and within a week they were back fixing our chiller. It took a few hours and our unit was back working like new. Id highly recommend."

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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
