If CB says you have 2 then you are proven to have a hack. Just curious,
you say he upsized you 25%. What size unit did you have , what did he
install, what was the old units efficiency and what is the new units
efficiency. I will bet the numbers don`t work. Now im no pro but when I
see one thing go wrong on my jobs I look and usualy find the trend
continues. Burnham would be interested also and will help.
