Duct Insulation in Mt. Vernon, IL

When ductwork or air handlers are located in an attic, they have to work much harder to keep your home comfortable. Battling temperatures upwards of 140 degrees F in the summer and as low as 30 degrees F or less in the winter, your attic air handlers need all the help they can get keeping your conditioned air the temperature you want it to be! Air sealing and insulating ductwork and air handlers is a great place to start. Dr. Energy Saver encased this ductwork junction with spray foam insulation to seal any leaks, keeping that conditioned air traveling to where it needs to be---inside your living space!

Attic Fan Cover in Mulberry Grove, IL

Dr. Energy Saver will construct an insulated containment box around the fan and then air seal the assembly so that it doesn't leak your conditioned air (and money) to the outside. A hinged and weather-stripped lid on the box can be lifted open during the summer months and closed the rest of the year.

Spray Foam in Hoyleton,IL Before

Spray Foam in Hoyleton,IL

A kneewall space is created when a finished room is built within a sloped roof. Often, these walls are “insulated” using fiberglass batting. Since fiberglass does not stop air flow, the insulation does next to nothing to air seal and insulate----causing rooms sharing walls with kneewalls to be very uncomfortable. Dr. Energy Saver St. Louis air sealed and insulated this Highland, IL homeowner’s knee wall with spray foam insulation. Now, inside air can’t get out of the house through the kneewall spaces and outside air can’t get in. This bedroom is comfortable again!

    By Helen S.

    We have already noticed a decrease in our power bills and the house is a lot more comfortable in the back rooms. My mold allergy headaches are gone. We used to have a lot of brown recluse spiders in the house and there hasn't been a single one since Dr. Energy air-sealed our house. This work was completed before the heavy rains in April and kept our crawl space snug and dry while others on the street had to deal with water issues. We are very happy we had this done.

    Michael Jones made sure he called to update me of his arrival time and actually showed up at the time expected. He and his other crew worker were eagerly willing to fix my roof ventilation and provided this in a timely manner. They went out of their way to make sure that anything I was needing to be done would get done professionally and before they left. My home was left clean and tidy. I would highly recommend Mike and his crew for any job.

    The guys who worked on my home were very conscientious regarding their work and left the work area clean and tidy. Gene also identified a possible source of a leak from the roof that may be causing water damage in my kitchen ceiling. He recommended that I contact a roofer which I did. Dr. Energy Saver stands by their work. I am very pleased with the service.
