When our on demand water heating system developed a leak I was relieved to find these guys. They were able to fix the problem and help with other suggestions to make the system last longer. The original installer is no longer in business and other technicians were not familiar with the unit. John was able to find the problem quickly and scheduled the repair immediately. John’s Home Comfort was highly responsive, provided excellent service and was extremely responsive when we needed to install a new tankless water heater quickly. Grateful for John’s flexibility and quick response during a busy time, squeezing us in when every other service provider was only booking weeks away.
