A WASTE of Time and Money. We had to use Ace through our warrantee company and what a terrible experience. We had our AC unit blowing hot air and Ace replaced part by part making 5 visits in total, still not getting the problem resolved. In the end we had to get our warrantee company to send out another company who found that the lines were still clogged.
Ace never follows up even when they say they will and comes out when it suites them not the customer. I would not recommend this company.
