Size of A/C units

[Neal Lewis]

Ok, there are two brand new ICP Comfortmaster units side by side. Both 13 Seer. The shorter unit on the right is a FIVE ton unit. The taller condenser on the left is a FOUR ton size. Same footprint. LG scroll compressors inside. Confirmed with the model numbers, electrical requirements, and the builders invoice.

How can a five ton unit be physically smaller than a four ton unit?? All else being equal.

Maybe its the photo, but the shorter units appears to be wider. Also, are you sure they are both 13 SEER?

I've found no correlation between physical size and tonnage.

Doesn't make sense to me. Same brand, year and model but different box? No sense at all. I can't explain it.

As Jim said, the exterior dimension of the unit is not a good indicator of capacity. Variables can be size and number of coils (surface area and volume), refrigerant capacity, air flow, etc.

If I were to guess:

A. Different Freon. (refrigerants)

B. Different manufactured dates. Different model years.

C. Came from two different plants.

D. One is a heat pump and one is an air conditioner.

Do you have both data plate pictures that we can see?

Maybe it has to do with the amount of air to be cooled in the home and the size of the evaporator coil matched to the unit.

I wouldn't worry about it. We aren't required to determine whether HVAC or Plumbing engineers designed a system correctly - we're supposed to be looking at how it's installed and looking for physical deficiencies with the installed components.

ONE TEAM - ONE FIGHT!!!

Different compressors?

[airtrackinc]

yes size will be diffrent
