We were recommended by a friend to Pro Solutions Air. Tom came out to do a system check on our 18 year old AC unit. Tom called half an hour before his arrival. He was professional and great in answering all of our questions. He replaced the connector and gave us tips to keep system running. He was also nice enough to check one of our vents to see if we needed them cleaned. We ended up with purchasing the maintenance plan which gives us priority service and 15 percent off parts. We are waiting on a quote for what a new system would possibly cost. We would likely use them in the future!
