"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 FAQs, answered by experts

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.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Costs depend on pipe length, accessibility, and whether additional services are required.
