Water heater stopped working and I hoped they could repair it but they said parts obsolete and no choice other than replacing. Chrys went a got the new tank and had it all done in a few hours. A little expensive but I needed it done. I was really lucky to have Chrys as the technician, he was knowledgeable, polite and very efficient.

We called and spoke with Paul about our tankless water heater. We had an electrical problem and had inadvertently forgot to reset the breaker correctly. Not thinking about the electricity situation, we called Paul and he told us to check the breakers because it sounded to him like an electrical thing. He said he didn't want to charge us to come to the house and then find out it was a simple matter of turning the breakers back to on. So we had our son go down to the basement (the breakers are in the basement) and check them. Sure enough, two of the breakers were in the off position. As soon as we fixed that, the water heater came back to life. Thanks, Paul!!!

Lucas arrived at my home within the timeframe he mentioned over the phone. It’s also great that this company provides a link to track their route to help manage your schedule. I had two technicians come in for a quote prior to Lucas and he was first one who actually took out his tape measure and asked to check the vent coming from my backyard.
Lucas was professional and efficient. I had a follow up question the next day and left a message to their front office and he immediately returned my call within 5 minutes.

Wesley did a great job on a Saturday afternoon. Was without hot water for only half a day. He cleaned up after the install and made sure everything was operating properly before leaving. Couldn’t be happier.
