"Great people. They put down cloth to protect the floors from their boots. They tested the house before they started the work. They showed me results and explained them. They did the work, tested the house again and showed me the results again. BIG DIFFERENCE! They cleaned up everything afterwards, showed me and explained everything they had done and told me to call if I ever had any questions. Excellent!!"

"Words can’t explain how excellent of a consultant Julian is ! I was very indecisive about solar until Julian gave me all the information I needed on behalf of solar while saving me a ton of money. I reffed my whole family to him and if anyone is looking to go solar or get information on solar definitely contact Julian ! his personality is unreal making you feel more like family. I’m glad to be apart of Commonwealth energy !"

"These guys were fantastic! Mike really knows his heat pumps and it showsâ he was always available via email when I had a question, he walked us through the entire process for applying for the state heat pump rebates, and we couldnâ t be happier with the system one year in. Because of our Initial positive experience with Mike, we also hired Energy Monster to do our solar panel installation. Top notch, LOCAL company!"

"Ryan did excellent work. He explained everything so I could understand it. In just a few hours he rewired my electric heating system in my duplex. For the first time since I moved here (14 months) my heat is completely off !! I would give him 10 stars if it was possible, but here I would give him 5 stars."

Energy Efficiency Auditing questions, answered by experts

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.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

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.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.
