A technician came to home for check on my furnace for some $90 -call out service. After inspection, he proposed to replace the flame rod for a charge of $280! Apparently, it was overcharged and ridiculously costly. My research into the normal market price for such flame rod is in the range of $20 to $60. Definitely $280 is unacceptable. So I denied the replacement job.
Potential customers should be aware of this company!
