"Not only was Teresa professional and knowledgeable, informing me of the details of the tests and recommendations for what fixes can easily be done myself or with simple fixes. But gave detailed notes of affordable and recommended options for more involved fixes. Additionally, Teresa accommodated my disability well, and discovered two minor gas leaks, aiding me in calling the utility and getting immediate repairs. I'd highly recommend 5 lakes to anyone looking to improve their home energy use, or prevent airflow problems."

We are a full service high performance insulation company. We also perform home performance audits that include infiltration testing and infrared imaging.

"Lee's team of insulation specialists did a phenomenal job of spray foam insulating a very, very small crawl space in our home (as well as some boxsills). We have had several construction professionals in our home recently, as we are considering a major renovation to our house, and they have all commented on how well done the job is, and how amazed they are that insulation specialists were able to access such a small space. The team arrived on time, did their work quickly, and the administrative team was very communicative, personable, and kind. We'd highly recommend Duerst to others!"

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.

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

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.
