    Hi Guy & Paul,

    Thanks for taking such good care of us; everything is working fine (knock on wood!) I'm so glad you were able to coordinate with Tommy to get here; it was such a relief when we got back from vacation!

    See you soon.

    Dear Guy & Paul,

    I just wanted to take a few minutes to thank you for the great service I recieved with regards to the installation of my new furnace. I am so pleased with the professionalism, courtesy and level of service I recieved. Everyone was polite, respectful and a pleasure to deal with.

    I have to say, it was truly a refreshing pleasure to deal with such a family oriented, honest staff that exude integrity and great moral values! You should be very proud of what your family has built!

    I will definately highly recommend your company to anyone who is looking for someone in your field. Per my discussion with Paul, I will be contacting you in the fall to schedule an install for a humidifier attachment for my furnace.

    Have a great summer and the very best to you and your family!

    Respectfully and with much appreciation.

    Guy and Paul,

    I just wanted to let you know how happy we are with the Fujitsu Tri Zone system you installed. The air quality in our house has completely changed. WHAT A DIFFERENCE! Your team was professional and placed the highest priority on our needs. I would definately recommend your services to anyone interested in replacing or upgrading their heating systems.

    Thank you very much!

    Thank you for the quick turnaround on my broken down air conditioner. It happened over night and I could not believe it had to happen a few days before we were set to close. We did close on Friday, July 22 and you and your men were over the house today to put the air conditioning unit in. I want to give you a big hug and kiss for being so accommodating with us. I don't know what I would have done. The woman that bought the house originally was not going to inspect the house although at that time there wasn't anything wrong. The leaking air conditioning unit was okay a week ago. That's the luck I have.

  • David C. - Sandy Hook, CT


    Mark tells me that you did a great job! The furnace installation passed inspection last week- so we should be good to go. Thanks for taking care of our job so promptly and efficiently.

  • Fran & Gregg - Oxford, CT

    Thankyou! We appreciate how quickly and how well you get jobs done!

  • Peg P. - Brookfield, CT

    Hi Guy And Paul--

    I was sitting on my deck eating dinner when I heard a hum. It took me a couple of seconds to place the nice QUIET air conditioning unit on the side of the house....the one I was worried might be too loud when i was enjoying the peace and quiet of my deck.

    You probably mostly hear back from customers when they have a problem. I just wanted to let you know that i am enjoying my air conditioning and it is working just fine! And best of all, it doesn't disturb the peace on my deck! Thanks!

  • Gil R. - East Haven, CT


    I want to thank you and Travis for your patience, quality service, and commitment to being on time. We look forward to a continued relationship. I hope you and your family have a happy and healthy holiday.

  • Shaun V. - Woodbury, CT

  • Jan & John R. - Trumbull, CT


    Thankyou so much for the work you did on our new addition. You always do great work! It's finally done- came out beautifull!
