"I whole heartedly recommend Airco. Their team was experienced, skillful, friendly and professional throughout the duration of this job, from Joe's first visit to my home to discuss air conditioning options to Derek and Cam's final touches on the duct system. I had complete confidence in them, as well as in Steve, Danny, Frank and Patrick. Additionally, Airco's connections to MassSave and Commerce Bank meant financing and payment options to suit my budget. No more hauling loud and heavy window a.c. units up from the basement. Instead, I am enjoying consistent cooling throughout my home with no noise whatsoever. I am a very happy customer!"

I conduct energy audit tests for homes, whether they are colonial or brand new construction. I can recommend you various forms of weathersealant, thermal wrappings, and storm window techniques, saving you thousands in the form of long-term heat insulation tech-forward solutions.

"My house had problems with ice dams and ice build up on the roof. After they installed air sealing and cellulose the issues went away. Our house is more comfortable and stays warmer longer. The installers had a professional appearance and great customer service. Plus they were able to find us rebates thru the utility company to help pay for the project. Highly recommended!"

"This pro did a nice quality job for the most part friendly, clean, shoes off while in the house, the blower door test was great. The thermal imaging was a bit lacking no actual thermal imaging gun but some kind of app on his phone not worth what was charged for it. All in all house is pretty tight with just a couple questionable areas that I can take care of I would recommend the blower door test for sure."

"Yes the work was done. The two guys that came put in 7 windows and two big bay windows in one day. They did not even taken a break. They cleaned up the small pieces of scrap. Then one week later they came back and put in two new doors with the same professionalism when they did my doors."

Energy Efficiency Auditing FAQs, answered by experts

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.
