Michael was prompt, professional and very personable.we enjoyed having him in our home.we have large,old dog and he gave him lots of attention so he didn't feel threatened having Michael in his house as we have very few visitors.Michael was knowledgeable about our unit and explained everything in detail to myself and my wife.thank you so much for sending him our way.but I must say, everyone from this company has given us excellent service .they have all been kind and considerate.just a pleasure to do business with.i would recommend this company if you have heating needs.we will look forward to having Michael come see us again next time for our annual check up.
