Up selling is the reason for systems bring replaced within 10 years. The typical Florida technician is trained to upsell rather then repair the problem. He receives a commission for his efforts. I am a commercial HVAC professional that knows full well how these guys operate and frankly I find it disturbing and IMHO borderline criminal .

My only comment here is that I know for a fact that several of my close neighbors when having AC problems, it was found the air handler coils had cracked. Probable due to vibrations in the motor. I am now on my second unit, and fourth compressor. Two on each unit. Is it your opinion that the coils found on today's units are as good in quality as the old copper coils of say 40 years ago???
