After getting several quotes to replace my 40+ yr old heating/AC unit, I decided to go with Ace, primarily because Curtis, who oversaw the project, was so thorough and straightforward when he did the initial inspection. Based on his knowledge, he took the time to point out critical factors that the other vendors either missed or ignored. The crew was professional, courteous, and experienced — they took the time to do an excellent job! I would recommend and use Ace again.
