"On a Friday night, our boiler shut down. We reset it and eventually, it started working on its own, but we called Jeff and left a message, because who knew whether it would stop working again. We didn't indicate that it was urgent--since we had heat at the time that we left the message--but Jeff called back shortly after we left the message anyway. He said that he'd be in our area and would take a look at the boiler the next afternoon (a Saturday). That turned out to be a good thing, since the problem recurred a couple of times overnight. And then, when it became apparent that the boiler was shutting down constantly and our problem needed to be fixed right away, he went to complete his other scheduled jobs, and then came back to our house and stayed until almost 8pm on a Saturday night to repair our boiler. The price was very reasonable too! On top of that, it's not as though we were regular customers. He never heard of us before, and yet he went waaay out of his way to accommodate us. On a scale of 1 to 10, we'd give him a 14. He's going to get all of our business from now on, and he should get yours too!"

"Recently, I had a three unit heating and hot water upgrade. During the install, it was determined that the electrical wiring was out of code and some of the wiring had been done incorrectly. Carmen and his team came to the rescue. Carmen knew exactly what needed to be done and went to work immediately to fix the issues. He and his team were polite, knowledgeable and professional. He explained what needed to be done and answered all my questions. Who could ask for anything more? I feel good and safe about the work that was done. The honesty and earnestness that was shown and given has earned my trust. I will call on Carmen and his company for any future electrical services. Thanks guys!"

"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!"

Energy Efficiency Auditing questions, answered by experts

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.

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.

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.
