AC not blowing cold air - was told have leak in coil- Cost?
AC was not blowing out cold air and I had a HVVC tec come and look at it. He tested for leaks and said there was a leak in the mail coil (big coil in upper par of furnace). It is very low on refrigerant so he said coil needs replaced. Estimate is around $1000 without cost of refidgent (freon). Says with the new coils they are bigger and do not fit in the old furnace so the top part of furnace needs a new box. Does the estimate and what he says sound right?
