Bill and Total Energy Service were a pleasure to do business with. Bill spent significant time walking us through the process, talking scenarios and sharing his expertise. He worked with our unique situation, was patient with our decision making and fit the project into our schedule. I could go on and on, but mostly I appreciate the way Bill cared for our family and the way he conducts business

We got multiple estimates to get central AC installed in our old home... and either we were told it was impossible or it was going to be extremely costly. This company, with Andy as our project manager, came up with the best way to install it and at a reasonable cost. Two summers after getting it installed, we are enjoying the nice cool house!!

I had the pleasure of working with Bill on some home efficiency upgrades. Bill explained every step in the process, always answered any questions I had, and was able to find solutions that worked for me. Bill proved to be a leading expert in the home efficiency field and I look forward to working with him on future projects. I highly recommend anyone looking for home efficiency upgrades, including those with rebates, to reach out to Bill and the TES team.

I’ve had a lot of work done in my home and total energy was by far the best, honest, and most professional team I have ever worked with. They started the work when promised, kept me apprised of the status and even worked to get me back a higher rebate amount. Absolutely amazing and I would recommend them everyone!

Look no further if you need HVAC help. I can say enough great things about Total Energy Service. Andy and his team are THE most professional contractors we have had the pleasure of working with. We have an older home and met with so many HVAC companies regarding installation of a central AC system. Where some businesses did not even want our business, or told us central air conditioning would never work in our home, Andy came in and really put in the time to find a creative solution that will... cool our home, and at a reasonable cost. And then when the work began, his whole team was on time, responsive, so polite and extremely hard working. Andy himself was on site every day checking in and giving us updates. They all could not be nicer and it was a pleasure having them work in our house. They cleaned up after their work and laid down towels so as not to track dirt into the house. The system looks beautiful and we are so excited to throw away our window units and enjoy a cool home in the summer. Thank you TES!!read more

Excellent company. Highly recommend this company for installation of mini-split AC/heat pumps. All interactions and work done was professional. Actually enjoyed working with their employees from sales to technicians. Price was very good for top rated equipment and installation.

Andy and his team are exactly who every homeowner would wish to have a phone call away. Andy literally went the extra mile to be sure our installation was on time. His skilled and professional team worked carefully and skillfully, putting in added effort to make sure the outside unit had the perfect placement spot. As we learned about our options and discussed prices, we know for ourselves what we have heard other say : TES is an ethical, fair, professional and kind group of people. We thank... them for making such a difference in the way they do business and highly recommend them.read more

We got quotes from 5 contractors for having AC installed in our 90 year old home. We did not have existing duct work and a ductless mini-split system was the best choice for us. Andy spent the most time of the 5 contractors thoughtfully assessing our house and providing a detailed proposal. The pricing was fair and in line with the other quotes (and 30% cheaper than our current heating company!). Andy was very responsive to all my questions and emails in advance of the work being done. He told... me exactly what would be happening and when. The electrical subcontractor he recommended was equally responsive and detailed.The installers, Bob & Brandon, were terrific. They were early to the job each day, friendly, respectful of our time and property, clean, and hard working. We had 4 ductless units installed. They consulted us on placement and did a great job. They were equally careful and clean with running the refrigerant lines in the basement and down the sides of the exterior of the house.My father was the most careful, precise guy with home projects. When Total Energy Service finished this job, I told Andy that I wished my Dad was still alive so he could see what fine, professional, careful work they did.We could not be happier with the new system. It's so whisper quiet after 15 years of noisy window units to cool our house. The cooling is evenly distributed throughout the house. Total Energy Service was a great choice for the job. They are total pros, and we are completely satisfied.read more

Andy and TES are consummate professionals. Andy spent time with us going over everything, explaining complicated concepts in a very easy to understand manner. His staff were also all professional, on time and clean. The systems work very well, and they are very detail oriented. The pricing was fair, and my wife and I strongly recommend TES for all of your air conditioning and heating issues.

I have used Total Energy Service twice now. The first time was in 2016 replacing an existing heating and cooling system. I was so pleased with the work and professionalism, we went with them to add a central AC to the house NY lady and I bought recently. They still do great work and were a pleasure to deal with. I highly recommend them.

When I was in need for a new HVAC system, I reached out to Bill Dondiego for an energy evaluation for my home. My monthly bills were quite high especially in the winter, and the temperature of my home was never comfortable. Andy Andeskie provided a thorough evaluation for the type of system I needed which would be appropriate for the energy needs for my home. He recognized the challenge of having a heat pump in this area and worked to find the best one. Bill was extremely thorough and made... numerous recommendations to improve the efficiency of the new system. He was a fabulous help in processing the energy rebate application and obtaining the rebate itself. My system is running great and I recently noted a reduction of my energy bills by 28% annually. The difference in the system has been tremendous.read more

I've worked with Andy and Bill of Total Energy Service for more than 10 years. I find that they are honest, trustworthy, hard working and extremely knowledgeable. I have seen them with clients take what can be rather technical subject matter and explain it in easy to understand language.I recommend them to friends, homeowners, and builders monthly and have always had positive feed back from my referrals. They are 5 Stars.

TES and especially the owner take their 365 day/24 7 promise very seriously. Unbelievably responsive with honest and straightforward pricing. Extremely reliable advice. We only wish they could expand so our vacation home could be serviced by TES as well. Very trustworthy.

We used Total Energy Service replace both our 1st floor and 2nd floor AC/Heating systems. We received quotes from 4 different contractors and TES was very competitive from a price perspective. However, the reason we chose TES was the level of professionalism and honesty they displayed in developing their proposal - diligently measured every room, discussing which features would and would not make the most sense based upon our lifestyle and the construction of our home, etc. During and post... installation we could not be more pleased with our decision to work with TES - Andy (the owner) is terrific to work with as is his entire crew - very courteous, neat with their work and very responsive. All inspections passed without problems. We highly recommend TES!read more

I replaced my two heating and two cooling units for my home with T.E.S. recently and received the best service I could expect.The owner handled my business directly with great efficiency and professionalism. His crew delivered the job on time and diligence.I chose this company after making an extensive research and receiving at least four different quotes. I got the best technical information and honest approach from T.E.S. on the top of the best price for the brand of units I was looking... for.I certainly highly recommend this company.read more

I have been dealing with TES for a very long time. They have serviced (and installed equipment) in three of my houses (and many of my families houses) over the years. I have always found them to be honest, caring and professional in all my dealings with them. They have always promptly returned my calls and performed service calls quickly.I had them install a new central A/C system in my current home last month. Obviously I haven't used it yet but the installers were extremely careful of my... house and belongings, were very courteous and cleaned up after themselves.Would highly recommend this Company to anyone looking for heat and/or A/C service or installation! Andy, Bruce, Ed, Steve and Javier have always done a great job for me and my family.read more
