Ultrazone NCM 300

Post by jgeshay »

I have a 3 year old house with a YORK unit at 96,000 BTU and a fairly simple 2 zone system.
We also recenlty added a basement apartment and tapped into the 1st floor zone to get some air circulation etc.

A recent routine call from a local service contractor said we are having a "short cycle" problem.

The explanation of course that I need a larger unit.

They have not even looked at the EWC controll's for what I believe is a zone malfunction. Each floor is about 1200 sq ft.
If the zones are working properly (diffent heat and cool times) I would think that I have enough BTU.

What do I look for in diagnosing ( helping them ) a zone malfunction?

Thanks
