I live in a condo that has a built in air temp air

Customer Question

I live in a condo that has a built in air temp air conditioning unit and these condos were built in the 70s , we moved in in July of 2014 and the air was working fine but sometime later it just started blowing warm air. The model number is ***** serial number 7G22151 .. Our neighbors units seem to be working fine... Should I try to add refrigerant? Or is there a way I could replace the compressor or motor for this type since the company no longer exist?

Hello again,

The system is 40 years old, about double the average life span.

If you have the money, replacement will be a good idea, every aspect of that system is deep into its failure range, any money you spend on it will be a waste longer term.

The compressors and motors however are replaceable, $800 to $1,200 to replace the compressor, $400 to $500 to replace each of the two blower motors. A refrigerant leak repair and refrigerant recharge will cost you $400 to $500 as well if the new R-22a refrigerant is used not the now obsoleted and very costly R-22.

That is way too much money to spend on a 40 year old system in my view.

Let me know the region of the country you are in so that I can assess the load conditions, and size of your condo, and if you are on the top floor, or a floor somewhere in the middle of the building.

Tell me how your system is laid out, a few photo's taken at a distance of 10 or 20 feet will allow me to put it into perspective, I need pictures of the unit outside the house, and the unit inside the house.

Use the paper clip icon to attach the pictures.

We can go from there.
