Justin and Dave were courteous and extremely knowledgeable about all facets of their profession. We have an immune compromised son. They had no problem wearing a mask and the protective shoe covering. They were very accommodating. I really respect that about them. Justin pointed out all areas of concern and resolved many of our current issues. The water heater was not working and diagnosed the problem within minutes. Thank you very much for assigning Justin and Dave to our house. They made great recommendations as to the purchase of a new water heater system which included a discount. I sincerely hope they will be available to help install our new system. I feel comfortable knowing they would be working at our home.
