How big?

[Dan Blanchard]

This is a Trane Model Number. How many ton would you say this is? It is 2 years old and cools a 1,100 square foot 1969 site built home.

I have run into this a few times. The link below will tell you some info

Ted gave you a link that tells you what you have. The best way I have found is to just look at the numbers. Look for numbers that are close to being multiples of 12. The "37" in the middle would tell you that this is a 3 ton system, which could be a little big for an 1,100sf home.

Using this method to figure out the size of of a condenser unit works I would say about 90% of the time.

Had an reputable HVAC guy tell me the other day, that now when they order or buy a condensing unit it is actually downsized 1/4 ton than labeled.

Example would be a 3ton would be a 2.75 ton.

Has anyone heard this.

Sorry, I gave the wrong link. I have several but that one at least told you something about it.

Yeah, What Scott said.

I actually did find that link interesting

That whole thing about the more efficient unit the smaller the unit for the square footage. The temp differential was talked about the other day. When I say temp differential I mean between the return and supply vents. The more efficient the units the lower that differential is. The three ton today had no more than 12 degrees difference. I think I will have to sit back and inspect these more efficient units and get feed back from folks with them over time before I agree with all that. One thing is I have been hearing about much lower cooling costs. I guess that is a big plus.
