"We met with 3 different companies to advise on getting solar panels. The first 2 companies basically just told us what size system we could get based on state and federal tax rebate levels. Heard an advertisement for Sunpro on radio and decided to call them; turned out to be a good decision. Kara with Sunpro was extremely informative and had a nice package put together for us to review. She even researched our home and had an idea of how much production we could expect with the recommended solar panels. Even after selecting Sunpro, I called Kara with questions about things I'd heard from others or something I forgot to ask. I never felt like I was a burden and she always returned my calls if I had to leave a message. The complete team with Sunoro were professional and eager to help. Satisfied with new solar system and looking forward to enjoying savings on electric bills.

"It was incredible!!!! They showed up in the morning at 7:15 sharp with 4 well-equipped gentlemen and left 3 hours later with my two brand new York HVAC units completely installed, floors were left clean, everything was absolutely impressive! They were very respectful and professional. I couldn't be happier with this experience and the price was very fair!"

"Economy Heating & Air came and got right down to business. The team was very pleasant and answered all of my questions. They installed a brand new AC system into my cute stubborn old house :). After the install the AC had a little hiccup. I called and they were at my house after a few hours, that same day, which is very rare. We got the problem fixed and I was told on multiple occasions “don’t hesitate to call” if there was ever a problem. I highly recommend this company. I would give ten stars if I could."

Energy Efficiency Auditing FAQs, answered by experts

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

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. 

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.
