Get another tech out, did he clean the burner.
The BBB only takes complaints if they mediate the case, you wont find
true info with them. I hired a guy I found out to late that he lost 15
small claims cases in 3 yrs, none were listed in the BBB. The BBB is
honestly a joke. Court records are better and your city lisencing dept.
What size unit, brand, model, Goodman or Lennox, how hard is the
instal, how much duct work, etc.etc , nobody can say.
I had a price of 2700 for a Carrier infinity 93.5% with VS motor,
but easy instal, Again get prices and another tech to ck your unit
