Home Advisor recommended 3 names when I needed service on our a/c. I chose Cool Air Solutions after speaking w/Nick & we scheduled service for the following week between 11-1. However the day before my scheduled service, Nick called to remind me of our appointment the next day between '2-4' but I was planning on 11-1. I called him back to correct the time but although he apologized for the error, he said it could not be changed but that the serviceman would be out as soon as possible. The serviceman, Adam, did arrive at 2 & was very respectful, friendly & efficient. He didn't have one of the parts I needed, so had to return to the warehouse to get it. But he promised he would be back & get it fixed the same day. I was thankful he delivered & was good on his word. He completed the job by 5 & was a pleasure to work with & the A/C is working well! The job was very expensive & had I not been pressed for time, I would have called around to find a more reasonable price.
