"Highly advise not to use them for any installation jobs. Sloppy work, incorrect with regulator placement and double billed after another experienced technician did the job. Even the experienced technician did a half assed job reconnecting an exhaust vent that he decided to remove to run the gas line which did not need to be removed. cannot get ahold of customer service to discuss or dispute the service bill which then has my oil and gas deliveries on hold. I prepaid for the gas delivery while under dispute and am being double billed. I may just find a more reliable local person as this big time company with small time feelis simply not working out."

Jim Moon started Gutter Helmet of New England in 1993. Gutter Helmet quickly grew and homeowners began asking him to install other products. What started as a gutter protection company, quickly grew into one of New England's premiere home improvement companies, Moonworks Home Improvement. In addition to Gutter Helmet, Moonworks also provides high quality products including; Heated Helmet, Ice Defense, Dr. Energy Saver, and GAF Roofing.

"I would void these guys like the plague. The original estimate for their "Ice Defense" system was # 3700 and I was told I needed to figure a couple of hundred dollars additional to have their electrician connect the wiring. After the install, I come to find out that their electrician actually wanted over $ 5000 to do the wiring. That's right FIVE THOUSAND ! After a months worth of e-mails and calls back and forth they finally hooked me up with a different electrician that said he got calls like these from a lot of their customers and the cheapest he could do it for was THREE THOUSAND. More calls and more e-mails and they finally agree to split the cost (to avoid small claims court), and the units are finally wired up. Of course by now the first winter is over so I never actually turn them on until the following winter. When I finally do get to use them, my first electric bill is almost $300 higher than any previous bill ever. Contacted them about that and never heard back. Just had them on this winter for ONE DAY during the last storm and my bill is almost $150 dollars higher than the previous month ... FOR ONE DAYS USE. A complete and total waste of time and money."

For over 20 years, Moonworks has operated around one core principle, that the customer deserves the very best. Over the past two decades, Moonworks has expanded the product line include quality brands like Gutter Helmet, EcoView windows & doors, Dr. Energy Saver insulation and energy saving products, Ice Defense featuring Heated Helmet and GAF Master Elite certified roofing. Though our company has expanded, our principle remains the same: provide first-class customer service and offer the very best materials combined with professional installation.

"i have been acting as an agent/advocate for my mom who is 87. she had a roof installed which has had numerous leaks. 2 in garage (now taken care of) where solar lines go through to roof panels.; 1 from improperly sealed window (also ok now) leaking into 3 season porch, causing water damage; 1 around improperly flashed chimney (paid another company $1800 to repair), and now, another one where roof meets vertical end wall of house (leaking into 2nd floor ceiling and down wall into kitchen). Have been calling company for OVER A MONTH and still have not gotten any help from them. They DO NOT RETURN PHONE CALLS!!! Customer service (Ashley and Ryan) have both "left messages for Jesse" as well as "reaching out to him personally". I now have left messages on his cell, and WILL BE FILING COMPLAINT WITH BBB, Office of Elderly Affairs, AG, and State Board of Licensing!! ****STAY AWAY*** ***READ REVIEWS*** (here AND on other sites!!)"

Energy Efficiency Auditing questions, answered by experts

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

While installing your new furnace, you should consider hiring a pro to perform a home energy audit . This audit will give you a handy list of any projects you could undertake to improve your home's overall energy efficiency rating, including replacing or sealing windows and insulating the attic. These improvements can help save you money each month in utility costs.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

Costs depend on pipe length, accessibility, and whether additional services are required.
