I had to put in a new furnace, so I shopped around, and found that Day & Night Mechanical Solutions Inc had the best prices. The staff was amazing, and everyone was super friendly, laid back yet very professional the entire time. The office staff was great about voicing our concerns from the day after installation. There was a problem in which the furnace itself was too big for our home, so it kept shutting off. They came out immediately to fix it. It was put in on Friday, the problems started on Saturday, and by Sunday, it was fixed. We've used them to service our old unit, but this was our first big purchase from them. They were fantastic!
