Dominick made sure my furnace and its connections were all working well, and replaced the filter. He figured out how to remove the barriers we had invented to keep the cat out of the furnace area, then made sure everything was back in place when he was done. He was very kind (and patient) teaching me how to use my thermostat. A very nice, knowledgeable, capable young man. And reliable, too. I highly recommend Sustainable.
Response from the owner:We are so glad that Dominick was able to help you get your furnace tuned up for the winter. We look forward to continued service Mrs.Lewison!

They came quickly when our hear wouldn’t start, fixed it immediately, did the fall check up, and the new man couldn’t have been nicer. 👍
