It was a great investment, our home is warmer, and I no longer hear the jets going over head. Thank you.

By Terry

Still can't say enough about your workers, Guatalupe and his associate (forgive our not being able to spell or pronounce the name, our bad). They were magnificent. The work site was impossible, the weather cruel and unforgiving, the work itself just plain nasty. Our observation is that both men obeyed a code of manly honor that proved more effective than any amount of money. Again, these two men cannot be compensated or valued enough by their employer. Thank you and may God bless them both forever.

Frank Nennig is excellent !

By Ryan

Absolutely a great job. We've noticed a significant change in the temperatures inside the bedrooms. We also unexpectadly addressed an odor issue that was flowing down from the attic into the bedrooms on hot days. We're extremely happy with the outcome!!

By Jim

We have not gone through another winter yet - and are very interested to see what differences we will have in our heating!

By Russell

Frank Nennig was very helpful in assessing our overall energy loss issues, and suggested solutions that had not occurred to us. The installation crew was very tidy; we had minimal cleanup after they left. Overall, most satisfactory experience.

By Rob

Reid was very helpful about any concerns we had about the job. His crew was fast and efficent doing the job and took the time to answer all the questions we had. They did a great job !

"I just got home and I had to write you about the fantastic job the guys did. It was so cool last night that we turned off the air conditioning in the house. Well, Lori didn't turn it back on today, and it's only 73 degrees in the front bedroom! I suffered all weekend from the heat, and in only a few hours it's cooler up here than it has been all weekend *with* the air conditioning on! I am so pleased that I went with your company. Please express my appreciation for all the hard work you and your colleagues have done in such a short period of time. Thank you so much"

Wow such a difference! The upstairs stays cool. We don't have to turn our air conditioning down so low. So glad we did this! Thank you.

I discovered Dr. Energy Saver on the Internet in the summer of 2018 when I was researching remedies for ice dam formation. The video presentation I found was clear and concise. I response to my call, a very professional evaluator (Tim D.) showed up and appraised my situation. Apart from giving me a thorough and understandable explanation for my problem, he informed me that my existing insulation contained asbestos and would have to be removed before the necessary improvements to prevent another ice dam. This led to another search for an environmental contractor to remove the asbestos. Fortunately, Tim had acquainted me with a trust fund which was set up to help ameliorate the costs of asbestos abatement, and which eventually reimbursed me about $4,000. Once the abatement was complete, the Dr. Energy Saver crew (supervised by Tim, Ray and Sue) completed the air-sealing and installation of new cellulose insulation in a single day in December 2018. There was an immediate noticeable improvement in the warmth of the house: the wood floors were not so cold! I have not looked for changes in my gas bill yet, but I am content that the house is much more energy-efficient. There was one minor glitch in the process. After the new insulation was installed, I observed a persistent small area of snow melt on the roof that could potentially cause an ice dam. After I reported this to Tim, he came out to the house and analyzed the problem. There was a subtle leak of warm air from one of the walls adjacent to the shower enclosure in the bathroom. Tim took charge and arranged for his crew to tweak the air sealing in this area. I think they may have done an “over-kill” job, as it looks like there is no way for air to pass into the attic. This just in: the latest information about natural gas consumption indicates a decrease of about 30% over last year’s consumption with roughly the same average daily temperature.

Very professional inspection and recommendation for insulation solution that met our needs. Showed up on time and work was done effectively, without drama and very good cleanup afterwards. Looking forward to warmer rooms as a result

Leslie S.

I really can't thank you enough for patiently walking me through all the improvements you and your crew were doing to make to our "very difficult to work in" attic. You were great. And please tell John how much I appreciated his ticking with it 'til the end. Not an easy task. Things turned out better than I expected and the enclosure for the staircase is very easy to move and put back. Thanks much! The house breathes

Attic Insulation in Wilmette, IL

This homeowner did not know what was going on in the attic until we went up there during our whole home evaluation. They were very surprised to see the amount of organic growth on the roof deck along with the lack of insulation, ventilation, and all the holes in the building envelope. They hired us right away and we took care of it for them at a great price. Another satisfied customer!

Dr. Energy Saver was able to insulate and paint the basement of a Highland Park IL home, which used baseboard heating so insulating their water pipes was essential. Ax proposed a custom install using commercial grade pipe insulation for clean, finished look that matched their newly painted basement. The result was a clean looking basement that was comfortable and improved the performance of the rest of the home immediately. Our customers were thrilled at the immediate benefits.
