"I could only select ?Home Energy Audit? above as work I had done. I actually had attic and rim joist insulation. So happy that I spent the money to get my home insulated. There is a noticeable difference. Well worth the money. Thank you!"

"My husband and I somehow have energy bills that are much higher on average than our neighbors according to the energy company. So we're interested in adding insulation to our home and possibly replacing some windows plus two patio doors. Before spending the money, we thought it would be smart to do a home energy audit first to see if it is worth the investment. We are generally comfortable in our home, but it seems we are overpaying to keep it that way.

There are several energy audits offered by Excel, which is what we were initially going to have done. However, my husband was referred by a colleague to Hoffman Weber Construction who had some attic insulation put in his home by the company over the winter. Since they offered free estimates and we heard the work was done well (he told my husband his bills have significantly improved), we scheduled an appointment to them to come out and give us a quote.

A gentleman from the company called to confirm the appointment and my husband asked what they do specifically to know how much insulation is needed. He told him he typically starts with a consultation and asks questions to determine why we believe insulation is needed, then checks for moisture issues and performs and attic inspection. My husband asked about the Excel Energy audit, and the guy mentioned their company is putting together a new service that is very similar and offered us the program for free if we'd allow them to do our inspection as training for some of their reps. We agreed and had them come over yesterday to do everything.

They started with a blower door test which helps determine how much air our home is leaking, which was a shocking amount (81 inches - basically like a big hole in the wall we can't see). One gentleman who seemed to be the most knowledgable of the group showed us how it takes the measurements and explained everything very well. They went around with what looked like speed detection guns, but were used to show infrared. They figured out that our electric fireplace chimney had a significant issue that could be resolved with some insulation. They also showed us how much air each bathroom fan and air duct was actually flowing out compared to what is code. Overall, it was very educational for my husband and I and every person that involved from Hoffman Weber was courteous and respectful. They gave a quote on the insulation and windows, and we are currently looking into financing options. When/if we are able to afford it, we will be delighted to have this company come back out for the actual projects."

Energy Efficiency Auditing FAQs, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

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.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.
