First off I never write reviews. In my 58 years I've never come across such a genuine company. They came highly recommend by a coworker. My furnace stopped working 25 years old. I was calling around for quotes for new furnace and ac. I had some big name companies in then lutes. The quote was a few thousand less. Wow. They installed a new Armstrong 96% two stage furnace. New armstrong ac unit. New aprilaire humidifier and filter. First off they kept my house clean. ( they even vac the floor when done) the metal work looks outstanding. Everything works amazing. Very quitet. Even fixed the temperature difference up staris in our master. I can't say enough about this group of guys. The office staff processed my warranty registration and nipsco rebate. Over all I'll be highly recommending lutes to all my family and friends.
