This was our first time to use Day & Night Mechanical Solutions Inc. We had them to come out and install a new air conditioning unit and furnace in our home. Their employees were all very nice and polite. They seemed to have done a great job on the installation so far, and everything works fine. We are staying warm, and that is a good thing! They did not leave any kind of mess behind in the house, and I really appreciate that. So, I guess we are what you would call very satisfied first time customers of Day & Night Mechanical Solutions Inc.!
