I highly recommend Mark and was very pleased with the service we received from him. He took a lot of time to explain why our old furnace of 28 years should be replaced and how much better the air quality would be with our new furnace. The job of removing our old furnace and installing the new one was done exactly as scheduled and was done with cleanliness and pride. We were out of town during the installation and came back to noticeably better air quality in the house (I honestly didn’t believe I would notice a difference but both my husband and I noticed it right away), a garage and furnace room that had been vacuumed and left cleaner than it started and our new furnace working great. Thanks for a job well done Mark!
