Their sales presentation, when they came down, I thought was very good and very professional. The only issue I had was when I signed the contract, which I did at home, the sales person did not offer me the form that allows you to cancel within three days. I brought that to his attention and he pulled it out, but that was the only negative experience I've had with the company. They ended up replacing our forced air furnace and air conditioner and they did a great job.
