An AC man came out checked my system a few days ago and I was told
that I needed a bigger compressor/furnace.

Anyway all that to say, the AC guy told me that I needed to go with a
5 ton unit for my 1800 square foor home. I have a 3 ton unit now. It's
a Trane and the house is 21 years old.

Trying to diagnose a problem like this on the Internet is not the
solution because of so many variables and lack of details. The best
way I can help you is to direct you to competant service. Just
mentioning that you have a Trane unit, I suggest that you visit their
website to locate a Comfort Specialist dealer. Go to www.trane.com
and under the residential section, look for the dealer locator. You
will come up with a list of dealers and some of them should be labeled
as a Comfort Specialist dealer. I suggest you call those. If you
have several to choose from, you might ask each if they have any NATE
certified technicians. Not necessary but is a sign they might be
better technically.

If you don't use a Trane dealer, check the sites of other brands on
the internet to locate their premier dealers. You will pay more money
for a good dealer but doing air conditioning correctly will cost
less in the long run.
