Hello all,

I moved into my 3,200 sq. ft home about 1 year ago. I have 2 3.5-ton
Trane units (2TXCB036BC3HCAA). Last fall, I had to call the home warranty
people because my upstairs unit was not cooling properly (could not
maintain 77 degrees with 85-90 degrees outside). They detected a leak and
replaced the evaporator coil. Now that Summer is on the way, I'm noticing
similar problems. I've had a very experienced HVAC person maintain my
systems every 6 months (his visit 3 weeks ago was his third time working
on my systems). He verified pressures and charged me with 2 lbs. 10oz of
refrigerant.

Since then, the upstairs is still not cooling properly. It was 85 outside
yesterday and today and 80-82 inside. The unit is running constantly. I
don't believe it's freezing up because I can feel airflow at each vent,
but the air is not very cold as compared to the air which comes out from
the downstairs unit.

The downstairs unit is located in my cool basement whereas the upstairs
unit is in the hot attic. The downstairs is using mainly galvanized duct
whereas the upstairs is using the insulated circular duct. I've noticed
the airflow coming out of the downstairs vents is much more forceful than
upstairs. Also the air coming out of the downstairs unit is much colder.
Unfortunately I don't have the required instruments to measure the actual
temperatures in these cases.

I've logged a call with my home warranty folks so hopefully I'll have
another pair of eyes on the problem. Any other thoughts on what the
problem could be?

Thanks!

/Brian/

Yeah, several things come to mind. But, till a real tech can lay his hands
on it everything would be a WAG.

Thats an awful lot of cooling but since I havent seen your house I
cant really comment.

That would be mistake number 1. If you need an explaination then I
cant help you.

It appears your "very experienced HVAC person" is not very
experienced.
Lets call that mistake number 2.

I believe the problem is the "guy" that keeps calling the home
warranty company.

It takes money and quality to fix the problem. You dont seem to be
using either.
