Where's a good place to research the specs on my Goodman Mfg. Corp air conditioning unit? It's old and at the manufacturer's website they don't have any archives for documentation of legacy models.

My unit's model number is CPE36-1AB. I need to know stuff like how many tons it is, BTU, etc. It's getting time to replace it with a more powerful, more efficient unit. It's over 15 years old and has refused to keep pace with the hot Florida sun.

Is there some kind of massive clearing house of info online that has the lowdown on most models of AC units, maybe even in PDF format, that I can browse and hand to my AC specialist buddy to recommend a high-end model to replace it. We love the cool dry air but Aspen, Colorado is too far away (among other things) for us.

Thanks for reading and any solid leads you can send me.

Chill y'all :)

Your current unit is 3T. As far as checking on your current Goodman check Famous Parts . Com. They have a section on Goodman. As far as sizing new unit, insist that whoever you get from does a Manuel J

Ok thanks for the info, I'll do that. Incidentally, what's a "Manual J?"

It is the professional method of sizing a unit for your home. Considerations for doors windows insulation etc. Anything other than this is just guess work

Ok. But if a 3T was good enough (in it's prime), and we have since added on another 250 sq. ft to the house and plan to add another 250 sq. ft. in the future. You can see where a 15 year old unit of this model is not going to keep up.

Could an AC specialist buddy of mine just do some quick math and help us upgrade to a 3.5T or 4T and easily skip the step of detailed analysis? I mean, is there such a thing as "over cooling" a home if the guesstimate is off by a few thousand BTUs here or there? Living in Florida, I don't often see such a thing :)

Thanks for your advice.

Over sizing the unit will result in shorter cycles and you will not be removing the humidity. Your house will always feel humid and clammy. If your buddy is a A/C specialist, It won't take him long to do the manuel J. Anything less is just a guess, although if he is experienced in this field, it could be a good guess.

A friend took out before their house closed a Goodman Manufactured air conditioning unit Model HDC18-1AB. Does anyone know if it needs a remote control to start it once installed or is there a programmable wall thermostatic control? Want to know what we're getting into if we install it. Any help or sites to be redirected to would be appreciated. Thanks, Shelly
