Well, as things go, Mackay was a pleasant experience. My A/C went at the end of July and I had several companies look at it and only Mackay gave me choices - Leave it and just use the circulation fan, fix it, or replace it (with a written proposal having 6 choices starting at very basic option). I choose a mid range option and they installed it within days (not a week or weeks) Woo Hoo! The sales rep was knowledgeable and the tech took the time to make sure I was happy - very patient and informative. I now have a 10 year warranty for parts and labour with a company I trust - as I said earlier it was a pleasant experience.
