I had a major issue when I rented a condo and installed (replaced) the current air con.
On moving out the owner of the Condo only wanted to pay a fraction of the Costs of the New Aircon. Fortunately my handy man had saved the aircon and removed my aircon and installed the old one and made it look like nothing ever happened.
But would I recommend this to any other member NOPE. If you own it yes, replace the thing, but if you are renting (unless on a contract of 10 years+ ) No ... way
Edit: Sorry not a condo but more like a Studio it was.
