Great customer service and definitely affordable . My AC system died on Saturday night on hottest weekend of the year last summer ( 2013) ... 117 degrees. I called
Sunday morning and they were able to get a new 5 ton 13 seer unit installed the same day for $2595...$1000 less than competitors with a much better warranty . Then they sent another tech out today (Monday) to make sure it was running properly. You can't live in Las Vegas without AC and I think a lot of companies take advantage if that. I'm happy to say that TNA isn't one if them... 5 Stars!!!
