Tank rusted less than one year of installation. One star as they only installed John Wood tank and when I contacted... A.0. Smith, they refused to help stating it is due to condensation. I never had condensation issue in the past. In fact my old tank had zero (outside) rusting and I only replaced because it was 12 years old.Update: Reply to comment: I have asked you to install mixing valve at the time of installation. You had advised against it. I have never tried or installed mixing valve. So your comment is incorrect I gave you five star review at first and have revised only after having rust issue. I have not said anything negative about installation experience. I have contacted A.O. Smith too.read more

During a recent 'Heat Wave' our furnace malfunctioned - hence No Air Conditioning. Delta T Heating & Cooling was... contacted and Lomesh was at our house promptly. It was comforting to see that he was complying with all Covid-19 Pandemic Safety Requirements and was very courteous.He quickly diagnosed the problem to be a faulty part, contacted/visited the supplier and within a very short time had the A/C system 'Up & Running' again. His cost was more favourable than another Quote received. Thank you Lomesh for your knowledge and efficiency!read more

He did a thorough inspection of my A/C unit, explained all possible issues, and found the problem VERY quickly- I am so grateful! He was very informative, explaining the parts, their use, and what I can do for optimal performance in the future. The pricing was great, and I felt good paying for the amazing work that I received. I highly recommend Delta T Heating and Cooling Inc., and will be calling them again for all of my heating and cooling needs.read more
