The various companies that sell Trane and Carrier a/cs in my area are
advertising a lot. They are offering rebates. My system is 15 years
old for the outside unit and 7 years old for the air handler in the
garage. It is working o.k. now but I am tempted by these offers.
Does anyone here work in this field and can you tell me if there is
much difference in quality between Trane and Carrier. Will one
outlast the other? Trane cost more, at least it did the last time I
checked. Will Trane last longer? What are some questions I should
ask when I start shopping?

First of all make sure they do a heat load on your home.

You would be surprised that when your older system was installed you may not
need or need a bigger system.

A heat load will tell you what size system you need.
