"Dan and Josh were incredible. Not only were they both friendly and extremely knowledgeable, but the were early on the day the work was to be done. They explained exactly what they were doing. They showed me progress along the way. They had recommendations and were adaptable to my schedule. The results were shocking. We live in an old lake house and really needed to improve the insulation. There were spots where there was little to no insulation and some where there was insulation but not enough. Even the first night the difference was amazing. I can't recommend Dan and Josh enough. So worth the money I spent. You need insulation hire them. I promise you will be thrilled."

"Marlon ghosted us before finishing the work we agreed upon and paid for. He completed 75% of the work, then as soon as he received payment he became incredibly hard to reach, started dodging phone calls, setting up appointments and then not showing up. It was incredibly frustrating to have our time and money wasted."

Energy Efficiency Auditing questions, answered by experts

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

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.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

A good SEER rating is between 15 and 20. However, if you want the best possible efficiency, look for HVAC units with a SEER rating higher than 21. Keep in mind that the SEER rating doesn’t mean that the unit will reach that efficiency all the time, but it does have the capacity to operate at that high of an efficiency level.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.
