Carrier Weathermaker 9200 for LP/Nat? - DIY Chatroom

1Mike · 06-29-2009, 09:49 PM

My cousin is offering me a sweet deal on a HVAC system he bought for his home, but apparently never installed. It seems he lost his job, and then his home, and doesn't want to install it into the rental where he lives now.

Its a Carrier Weathermaker 9200 with 4 ton A coil unit. It has the inside Air handler – Gas Heat exchange -6” micro filter – outside compressor and disconnect (with whip).

He says it is setup for LP gas, but can easily be converted to natural gas (which we use).

Is something like this worth $300? Does anybody know if this unit is currently being manufactured?

My house is 22+ years old, and I think I'm going to need a new furnace / AC fairly soon.

A sweet deal is not so sweet when not properly sized and installed improper.

What is the sq ft of your house?

i work for a carrier dealer and it is easy to convert to natural gas. any carrier delaer should be able to order it for you and it is a hell of a deal but plumber1 is right it needs to be sized to your house

2550sq ft on two levels.

I'll pay to have it installed if that's necessary. I installed a FAG / AC in a house I owned about 25 years ago. I talked to the current owner recently and they said it is still running fine. But I know a LOT has change since then. In reading some of the threads here I've noticed a lot of terms I don't recognize- like "seer"?

If you are talking 2 levels meaning main floor and basement then IMHO you will be oversized for 4 tn A/C

If you are talking main floor and 2nd story floor then you may be slightly undersized for 4 tn A/C

See if you can post the model number of your current A/C this will tell me what you have now to see if you are close

You may want to contact a local contractor for sizing

Researching like you are doing is better than spending $300 for a system that can only be used for a boat anchor

Yeah, I want to do it right, even if it means spending more.

Its a frame house, with 1st floor and 2nd floor, no basement. HUGE crawl space (should've been a basement) is where the furnace is located.

I'm 6ft tall, and I can easily stand in the crawl space.
