A+ from start to finish! I had an ongoing roof leak that was coming from under my old a/C unit. When Sun Country pulled the old unit they found some of the plywood was severly damaged and they couldn't install new unit until I got roof repaired. They worked well with my roofer and got the job done the next day. I highly recommend them. From sales rep that came out to do estimate, to the office staff, and the crew in uniform, very polite, and cleaned up after themselves. They were not the cheapest but no where near the highest estimate. And to top it off, the include a three year (twice a year) service agreement with purchase!
