"Carmen and his team did a great job on helping me upgrade my panel as well as change my meter box. I also had an old wooden mast that they changed out and replaced with a much nicer modern fixture which was great. My house was old and I actually bought it many years ago as a forclosure renovation. So some of the previous work was old and not done correctly. Carmen, Shawn and his team were great to work with. I was worried that no one would take the job because the previous owner had not done a great job. Carmen and his team dived in and made all of the main wiring to the house beautiful and secure and safe. I would use them again for any electrical work big or small. In addition I would add his team comes very well prepared. They have every tool imaginable for the job and are ready to go. I am so happy I choose them. A local neighbor recommended him to me. I looked at their breaker panel and liked how neatly it was done. Thats why I choose Carmen."

Additional DBA - Airco Heating & Cooling. Additional email - [email protected]. Master Sheet Metal License: 1325 and Master Plumber License: 11593

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

We are a full service licensed home inspection company in Massachusetts we have been in business since 1996. Owner operated, no subcontractors. Mass. Home inspectors license #153, Certified ASHI member # 2552071(American Society of Home Inspectors) certified/licensed Massachusetts pest inspector WDI registry certified. Fees quoted are based on multi factors, including property size, age and type of property. Email [email protected]

"Set up an appointment for an initial 10 minute phone call to talk about what we wanted. Tom ended up spending 25 minutes with us and answered a ton of questions. We subsequently set up an appointment for an initial pre-build inspection of the foundation, framing, roof, and windows. Tom was very thorough. He obviously knew his stuff. Pointed out several items that needed addressing before the insulation and walls went up. Couldn’t be happier with the amount of time he spent, how thorough he was and how much he listened to all my stupid questions and answered them in a language that I could understand. We will have him back before the next phase starts and probably a couple more times before we close. Anyone building a house or buying a new home would be wise to hire Tom. Great piece of mind and cheap insurance. Plus, he’s a really nice guy to boot."

Energy Efficiency Auditing questions, answered by experts

If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. 

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

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.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.
