By Michael
We were happy with the quality of the work and the professionalism shown.
By Darin
Rudy Abel and his crew did an excellent job. They are a real asset to your firm. They are very professional and friendly.
By Constanze
I want to give a special shout out to Ken, the foreman of the second crew. Not only did he and Dan work faster than expected, he also went out of his way to accomodate me and make the process as seamless and painless as possible. He called ahead to let me know when they would arrive so I could open the door. He explained the work to me in detail, he even sent me pictures to my cell phone. When they left, the place was spotless and later he gave us advice of how to air out the attic so the smell of the paint would dissipate more quickly. He even offered to have a crew come by and place one of their industrial fans for a while to speed up the process. We ended up not needing this, but the offer was more than kind.All in all, we already notice the difference during these hot days and we can only imagine how much more comfortable we will be in the winter. We are very happy with your work.
By David
Great company Larry, well done. I can tell that excellent service and a product that exceeds expectations are the first priority of your sales and install crew. I would definitely recommend your company to others.
By John
I can't say enough about Rudy and his crew. Even before the job was completed, we noticed an immediate and significant improvement in our home temperature. I only wish they could rebuild the entire house from ground up! Should've contacted you guys years ago, but better late than never. I've already recommended Dr. Energy Saver to others. Thank you, and Kudos to you all.

Steve came out and spent 3 hours explaining everything that was needed. Clive and the crew did all the work in the attic and basement and now the house is toasty warm and bills cut in half. Professional, responsive and cleaned up after the work. Thank you!
By Douglas
Second time we've used Dr. Energy (first time was February 2013) and again very pleased with their work. The team I dealt with was the same as three years ago which says a lot and assured me that the job would be done well. Like the last job, Johnny and his work crew were very efficient and pleasant to deal with. Johnny explained all the work in detail and he and the crew left the work area looking as though they'd never been there. I recommend Dr. Energy without qualification. Thank you!
By Ira
Johnny Lopez and Ralph and Mark were totally excellent from start to finish. You are lucky to have such great employees.
By Shawn
Will use your company again & will recommend; found your company through CT Basement Systems, also through neighbor's recommendation. Great work!
By Vaughan
When the crew opened up the walls they found that the house had been insulated and they were not able to blow insulation into the walls. The company willingly changed the statement of work and reduced the price.
By Jim
We will probably have you back in Spring 2012 or earlier to install kneewall insulation.
By Victor
Overall a very good job!
By Laura
Johnny Lopez, crew manager, is a must have for any job with this company.
By Frank
Your entire company from sales associates to workers are professional and top notch! I am very happy with my decision to chose Dr. Energy Saver as my installers.
By Glenn
Larry Janesky ... you can be proud of Johnny, Rafael and Mark. They are awesome employees! I wish you all the best with your various businesses and all the best to you and your family as you rebuild your home in Middlebury, CT.

Johnny, Mark, Ralph, Clive did a very professional job.
By Robert
Dwight and his installation crew did a great job with the difficult work of air sealing and insulating my attic. They were always very professional, courteous and cleaned up completely when finished.
By Joseph
The crew was very professional and made sure that all my concerns were addressed to my satisfaction. You run a very professional company. Thank you.

Hi Roxanne, I just wanted to thank you for an outstanding job! Johnny and Rudy did a fantastic job just as you had promised. Please ensure you send Johnny back out to my home when you come back. I really enjoyed working with him. He is neat, detail oriented and a real perfectionist! The execution of the work was top shelf, and I appreciated the way you returned all my calls in a timely manor! I cant give you enough credit. I appreciate all you have done.
Jason M.

The doctor who preformed my energy evaluation was great. He was able to show me exactly what energy upgrades and repairs my home was in need of. The installation crew who installed my attic insulation and home air sealing were excellent and showed great care for my home.
Anthoney B.

All the guys at Dr. Energy Saver who installed the work in my Hartsdale home, especially Eric not only are professional but truly passionate about their job and company. I hired Dr. Energy saver because of their reputation and references I received. I will refer you to my friends and family 110%.

Dr Energy Saver was able to address our New Rochelle home's needs from basement to attic. The attic looks great, and the basement is dry! The work Dr Energy Saver does is superior to others!

I had Dr. Energy Saver seal and insulate my garage ceiling in my Greenwich Home, to help stop drafts and make my family room floor warmer. Now we will be more comfortable spending time in our family room!
Alex M.

I like the way the representative that came out explained every thing! I enjoyed the way the estimate was written and the R values were given. The install crew who came out to my Greenwich home did an excellent job in my home.
Jim J.

We recently had insulation work done by Dr. EnergySaver, led by Johnny Lopez and his crew. Johnny was great! Considerate and respectful, very neat, and kept me informed every step of the way as to what he was doing, what would happen next and any surprises he found along the way. They finished within the timeframe predicted, and cleaned up after themselves…completely…a rarity these days. The entire crew were upbeat, friendly and efficient. The project went really well, has made a big difference and we are very grateful to Johnny and his guys. I recommend them without reservation.

Just wanted to follow up and let you know that we’re definitely seeing benefits from the attic insulation. Our playroom had previously been near impossible to keep at a reasonable temperature on hot days (actual temp would be 3-6 degrees warmer than thermostat setting). Now it is right in line with the thermostat. Too early to see exactly what the impact on energy bills will be over a full cycle, but the space is definitely more comfortable in the summer. Thanks. 
Jan L.

Thanks Dr Energy Saver for doing a fantastic job insulating and air sealing our crawl space at our home in Riverside. Your level of expertise and the time you took to educate me on the best energy solution is really appreciated, our home feels warmer already!
Debbie B.
Stamford, CT
Rudy and his partner did an unbelievable job in my attic. They were such hard workers, and neither my brother nor myself could believe how well the finished product was insulated at the end. I went up to the attic to see what they did. It was very impressive. I'm sure even the sealed hatch will add to the condo being more comfortable both in the summer and winter.
James C.

Johny, Christian and Hector were the BEST! We appreciate the competent workers and team of Dr. Energy Saver of CT. 
Clara G.
Stamford, CT
I am very satisfied. The crew was respectful, professional, and very hard working. I hardly knew they were here. Rudy kept me informed and made recommendations while needed. They were polite and informative. Keith was excellent. Much like the salesmen for our basement waterproofing, he was informative, but not pushy. I used your waterproofing services years ago and the entire experience was terrific. When I saw an ad for insulation with Larry Janesky's name, I didn't even call another company. 
Lawerence M.
New Cannan, CT
The reason I called Dr. Energy Saver out to my New Canaan home was for environmental conservation. Dr. Energy Saver was able to recommend and install a new more economically friendly water heater in my home.
Brian M.
Darien, CT
The Doctor that inspected my home was very thorough, knowledgeable and professional. This is the reason I hired Dr Energy Saver to air seal and insulate my the ceiling and exterior walls in our Darien home. The energy upgrades that Dr. Energy saver has done are making our home more comfortable and energy effiient.
Jeff L.

Jeff the contractor " I opened up my clients house and the guys over at DR. Energy Saver did a phenomenal job, Ken called me every step of the way. The rep kept in communication every step of the way. I couldn't be happier with the guys they are really 1st rate and the guys did a GREAT job. Super job on all quarters. I happen to find you guys out of the blue and I do not regret it, you did a tremendous job and I will let all of my friends and family know about how well you work.
Mike L.
Darien, CT
You guys did a bunch of insulation work in our house in Darien over the summer. I just wanted to tell you how fantastic it has turned out for us.   I noticed it in the summer with the AC being able to run quite a bit less, but it's really noticeable right now. The house is actually warm, the floors are warm, and my basement that doesn't actually have any heat in it is totally usable.  You've made my 98 year old house absolutely wonderful and I can't thank you enough for that. But seriously, thank you thank you thank you!
Aprille S.
Ridgefield, CT
Dr. Energy Saver dis a great job insulating my Ridgefield home. We had a huge opening in the walls all along the front of the house that was hidden under a big 4 foot wide soffit.  They identified it with their blower door test and when they did the work, we saw how big of a continuous hole in the wall we had up there - no wonder the rooms were drafty and cold. I will recommend them to my family and friends.

    Insulation Transformation in Greenwich, CT

    This home in Greenwich, CT had old insulation that just wasn't doing the job. It was causing the owner's energy bills to rise, and their home was cold when it should've been warm! They gave us a call at Dr. Energy Saver of Connecticut, and we were happy to come out, and see what we could do to solve the problem!

    Our Home Comfort Specialist, Keith Saunders, surveyed the space, and quickly realized what needed to be done. He called on Dan Kiley, and he came out to install new insulation in the home. After removing all of the old insulation, Dan and his comfort crew installed our closed cell spray foam. This two part foam has a high R-value per inch, seals any air leaks, forms a moisture barrier, and absorbs sound. It works so well that it cut this family's energy bills in half!

    A homeowner in Greenwich, CT had existing insulation in their attic that was causing their home to be energy inefficient. They decided it was time to call us at Dr. Energy Saver of CT to help solve their problems. After scheduling an appointment, one of our Sales Consultants, Keith Saunders, went out to the home to assess the issues. 

    Then it would be time for one of our Foremen, Rudy Abel, and his team to work on this project. They installed an insulated catwalk so that this attic can be used for storage and be easily accessible. Then the crew blew in TruSoft Cellulose insulation. This would act as a thermal barrier to the home, regulating the temperature properly. Now this home will be energy efficient and the customer can watch their energy bill decrease!

    Insulated Cantilevered Level in Riverside, CT

    These Riverside, CT homeowners reported incredibly cold floors in the second floor of their home where the second level cantilevers slightly over the first. We sent one of our most knowledgeable home comfort experts Keith Saunders to the home in order to see what to do with the issue. The reason why this cantilever was allowing to much heat out of the home was because it had a layer of rigid foam insulation that was not air sealed, so it was allowing heated air to escape.

    Keith recommended we install sprayable foam insulation between the floor joists that are cantilevering outward. This was done by our crew lead by Rudy Abel. They removed the siding underneath to expose the cavities then installed three inches of the foam to reach an R-value of about R-12. The closed cell foam expanded to fill all the gaps in the floor joists which will prevent heated air from escaping through this access point again.

    The homeowners noticed right away the floors on the second floor were not nearly as cold as they had been in past winters! They continued to have additional insulation installed in their attic by Dr. Energy Saver of Connecticut.

    These Stamford, CT homeowners called Dr Energy Saver of Connecticut with concerns for their high heating and cooling bills. They were looking to invest in their attic by consulting with one of our Home Energy Specialists. Keith Saunders, an expert in anything home energy, visited their home to check out any shortcomings in their attic. He noticed there were a lot of gaps in their fiberglass bats insulation that was allowing their heated and conditioned air from the living spaces leak into the attic. Also, their air ducts were not completely air sealed which also was robbing the homeowners from their conditioned air.

    Keith suggested they air seal, ugrade their insulation, and build an area they could use for storage in their attic. We sent out Rudy Abel, a foreman with ample knowledge and experience in installing home energy products. He first removed all the fiberglass bats installed that had become compressed and were barely providing any insulation. He then used an expanding spray-able foam into any gaps and joints throughout the attic, including installing foam caps for all the can lights and air sealing them too. He used our Spray Foam insulation to completely seal and insulate all the air ducts. Him and his crew installed our Blown in Cellulose insulation so the attic can have an r-value of R60 to provide an ample blanket of insulation. 

    The homeowners now have an incredibly energy efficient attic that helps contain any conditioned air in the living spaces. The homeowners are already pleased with the work!

    Crawlspace Encapsulation in Stamford, CT

    The old-fashioned way to insulate a crawl space was to install fiberglass batts between the overhead joists. This is no longer recommended for several reasons. In a crawl space, fiberglass insulation tends to absorb moisture, which causes it to lose R-value and fall out of place, rendering it ineffective while also creating a mess. It is also an invitation to mice and other pests. To repair and insulate this crawlspace, we first removed the old insulation. To keep moisture from entering the space, we installed drainage matting beneath TerraBlock foam insulation on the floors, and the CleanSpace vapor barrier above it. On the walls, we used closed cell spray foam. It's perfect for a crawlspace environment! Closed cell foam cures dense and hard, and it forms an effective barrier against both moisture and air. When the crawl space was finished, the owners were able to enjoy a less humid and more energy efficient home!

    One reason fiberglass insulation is a poor choice for crawlspaces is that it is an area that is vulnerable to moisture. Where the goal is to keep moisture out of the crawlspace, and subsequently the home, fiberglass batts absorb humidity and lose R-value when they do. When we arrived in this Stamford home, we found that the insulation had already grown heavy with dampness and had fallen. After removing the ineffective fiberglass, we used closed cell spray foam on the walls and our CleanSpace vapor barrier on the ground to insulate, air seal, and block out moisture entirely. The owners of this home have improved energy efficiency and home comfort, and lower energy bills because of encapsulating their crawl space!

    CleanSpace Vent Cover in Stamford, CT

    In older houses, it is common for crawl spaces to have open vents installed. It was believed that the vents would allow fresh air to circulate through the area to help relieve moisture and humidity from the room. However, the air outside is often more wet and humid than the inside. Moist air that enters a vented crawl space will condense on cooler crawl space surfaces, ruining insulation and encouraging mold, mildew and wood decay. That air will also be naturally circulated up through all of the other levels of the home.  Encapsulating the crawl space with our CleanSpace crawl space liner is the recommended treatment for a vented crawl space in order to separate and shield the crawl space from outside conditions. Our Everlast crawl space vent covers won’t warp, rot or crack and, most importantly, they are airtight, helping to ensure a dry crawl space and more comfortable living area.

    Then it would soon be time for one of our Foremen, Rudy Abel, and his team to get working on this project. To insulate the crawlspace, they installed SilverGlo along the walls. This reflects heat into the crawlspace to ensure energy efficiency. TerraBlock insulation was also installed on the floors of the crawlspace to protect it from moisture but also keep it properly insulated. For extra moisture/vapor protection, the crew installed CleanSpace. A SaniDry Sedona dehumidifier was put in to prevent moisture and dampness, but also from any potential mold growth.

    This Brewster basement had traditional fiberglass insulation that was poorly installed and causing temperature fluctuations within the home as well as higher energy bills! The homeowner wanted a solution to control the drafts and unwanted airflow in their basement, so they decided to call Dr. Energy Saver of CT!

    The experts at Dr. Energy Saver of CT determined that the most effective solution for this basement was to install spray foam insulation on the ceiling. Spray foam was the best option for this home because it effectively fills voids and odd-shaped spaces and will not absorb moisture or lose R-value over time, unlike traditional fiberglass insulation. This product will stop air leakage and heat loss, effectively saving the homeowners money on their fuel and energy bills!

    Now that their basement ceiling is completely insulated with spray foam, these happy homeowners enjoy consistent temperatures throughout the home and a lower electric bill!
