I recently got off the phone with my brother who lives in Kentucky who informed me of his hvac system going out. He said he that he spoke with two hvac contractors who told him he could use either a 4 ton or 5 ton system of which will cost about $5000.00.
They said a 5 ton would be bigger and better however upon asking him how they arrived at such a conclussion he simply said that one had 45 years in the business and the other had 20 years.
No calculations whatsoever was performed…just walked around the home and that was it. jeez.
