"David called me within 10 min. of posting the request, & enquired details and gave me a quote for the annual maintenance. His quote was very reasonable, and was upfront about what is covered and what was not. He was on time, wore booties w/o asking (I am particular as we have a toddler), finished his job thoroughly & patiently answered every question I had. I had couple of other minor issues - he fixed those w/o any additional charge! He checked my water heater too, for no additional charge! He didn't oversell, and came across as genuine, and someone knowledgeable."
