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.

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!

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.
