My 13 year old Lennox coil needs to be replaced. The consensus sems to be don't replace just the coil but rather replace the entire system.
The first question I have is what should should the minimum seer rating be on my new system.
Secondly, is there a particular brand of system that is much better - or worse for that matter - than the rest? A couple of Bryant systems have already been recommended to me, one with a seer of 13 and the second one with a seer of 15. I live in southern Ontario, Canada so their is a need for air conditioning here for only about four months of the year.
