Dylan is a pleasant and professional technician. He called he was on his way and arrived as he said. Interstate Heating also sent a text and email about his arrival; there is also a link provided to a real-time map. He went straight to work and performed a thorough inspection and testing of the furnace. I feel confident we will have a comfortable winter. If you have Dylan come to your house, you too should have a good experience. Dylan, thanks again.

“Fast service, I call in the morning and had a tech at my home within a couple of hours. The tech, Ethan, was very knowledgeable and spent the time after to completely explain what he had found.”

“Interstate is a great company they are responsive and always do a great job for us. The Company takes care of whatever problem we may have as quickly efficiently and reasonably as they are able. You cant ask for more. Most times we get the same people who will come to do our work. In our case it’s normally Kevin for the heating and his Son for the cooling. They are a great duo both great guys and know our home our systems that are complex and they keep it all running really well with rare visits in between our normal twice yearly maintenance work. Both father and son and knowledgeable polite a pleasure to have in our home great with our dogs and everyone we have dealt with over the years at the company are responsive and personable. All their good work is really appreciated. We built our home about 7 years ago and I would recommend Interstate when designing your new home or maintaining your old home. To find a business these days that appreciate you and are responsive and know what they are doing are becoming a rare thing sadly. So thumbs up to everyone at Interstate and the great job they are doing!!
Thanks!”
