The guy below me wrote about fifteen reviews all on the same day, I think he owns an a/c business so I wanted to review ACE. Let me tell you, the a/c went out on a Sunday night, of course, I called a company and their tech showed up at 10:00 p.m. and told me the unit needed replaced. He got it running though it didn't last. I called ACE on Monday and Nick showed up on time about 1/2 hour later. He told me the unit didn't need replaced and fixed it, permanently. He also showed me a 4" filter that was sealed into the unit upstairs by whoever installed it. I never knew it was up there, 8 years, I didn't know it was up there. Nick was courteous and professional, he put booties on his shoes when he came inside my house and put down a blanket to protect the carpet when he went upstaris. I would highly recommend this company.
