"I recently had my attic insulated by this company and had a great experience from start to finish. The entire process, from the initial energy audit to customer service and the final installation, was smooth, professional, and well organized. The crew was incredibly kind, hardworking, and patient with all of my questions while they were on site. You can really tell this is a business with a family feel — everyone treated us with care and respect, and it made the whole experience much more comfortable. I would recommend."

"The two fellows were prompt and professional.. My two light switch issues were quickly corrected by using the proper light bulbs.. Those energy savers don't work on everything!  We are doing basement work and they did the wiring for new lights as well.  Should I need more done, I wouldn't hesitate to use them again.

"Hugh's Energy is a quality company and it starts at the top with owner-President, Tom Dromgoole. Tom made a site visit to my home to discuss details of the insulation including the process, timing, and outcomes; he answered all of my questions. He also came the day of the insulation to check on how things were going. His crew, led by Parris, was excellent - knowledgeable, efficient and clean. If you are considering insulating your home, just call this company and save yourself time."

Energy Efficiency Auditing questions, answered by experts

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

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.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.
