Scheduled a Lennox AC unite to replace an old one that died. They came on time, the price was very competitive. The installers were professional. What was most important, they pointed out five errors made when "another company" had installed a new furnace a couple of years ago. They not only corrected the mistakes, which could have caused serious problems, but they didn't charge us for them. It took them two hours to make these corrections. I would recommend them to anyone.
