Not enough information. Need complete data plate info. See what information is on the motor. what exactly is leaking, the evap coil? How old is this unit?...post back....just from a glance and condition, I would say this unit is not worth a repair even if possible...

is this a joke?...

IMO

@tigerdunes - thank you for quick response. adding a few pictures below, but I agree - it seems to be beyond the point of repair. I don't see a year anywhere, but my guess it was last repaired or replaced 20 or 30 years ago. I was hoping for some advice on what to ask for when replacing it, and how much it would cost, instead of going to condo association "recommended" hvac company and getting taken to the cleaners...

as to the leak - it's more like "dripping", and looks like condensation is just not going into pan, instead ending up on those side panels and dripping down.

I think you have a Carrier 42VB cabinet vertical fan coil. These are typically used in commercial applications. I had no luck finding a price on line. You will have to find a HVAC contractor experienced with this type of system. I would not be surprised if he were quote an installed price of at least $2000.

Get a quote from the condo's HVAC contractor and then one or two other quotes for comparison. The same Carrier model may fit the same footprint so you don't have to deal with modifying the baseboard molding.

thank you @mike_home! found one on ebay for 1.8k (ouch!) . this unit is also very archaic with manual controls and very rough thermostat - I wish we could put something more modern instead...

Note, that one on e-bay is the cabinet only. Here are the current specs and availability. Looks like there are some modern features in the newer ones.

I am currently replacing heat/cooling systems in a Co-op from the 70s. In New York a fancoil unit replacement with installation will be around $4-5,000 per unit. Some buildings will also require you to replace the pipe branches from the riser. This also requires a system shutdown which is usually a charge from the building management (this is because they have to fully drain the whole system and if you live in a tall building that's a lot of water getting flushed). Your HVAC guy should be able to replace the pipe branches. Sometimes you might need to hire a plumber separately.

The units will be direct fit (meaning same size as an existing unit). The sleeve, the exterior, that I see in the photo seems to be in pretty good condition. You can save some money on avoiding to purchase a new one here. But they're usually cheap, around $200.

If you want to incorporate a smart thermostat system like Nest, you might need to also hire an electrician to run low voltage wires to the control system.

Hope this helps!

Another tip to avoid extra costs after. Ask your HVAC guy exactly all of the steps required for the replacement and made sure he adds them into the contract so he doesn't try to charge you extra after.

They will always put in their contract that whatever relatable damages are not in their scope to fix after. For example: repainting the wall or replacing sheetrock holes. So watch them carefully as they tend to get sloppy with the work.
