 Trustindex verifies that the original source of the review is Google. Adam replaced my old Rheem gas hot water system with the iStore 270L heat pump. Great experience, everything went smoothly. Installed product looks very neat. Good communication, he was happy to answer all our questions and gave a good price too. Highly recommended.

 Trustindex verifies that the original source of the review is Google. I highly recommend Adam. He was able to come out on the same day I contacted him to diagnose an issue with our hot water system. He explained the problem clearly and provided me with different options and information regarding replacement.

Once I decided on the replacement, he had the new system installed within just three days of my initial request. The whole process was quick, professional and straightforward. Very happy with the service!
