This a/c #aircontitioner unit was found on a flip house. Seller told the new buyer that the a/c had just been installed. It had but it was 6 years old, compressor not working, wrong indoor coil #R22 for this a/c. Not all are like this, but this is why a qualified Home Inspector #homeinspection is important.
As of Jan 1, 2020 the #R22 freon R-22 is no longer available. It is in short supply so the price has risen accordingly. The price of new systems using the new 410a freon are also rising quickly. It would be a good idea to get your air conditioner #maintenance checked to see what kind of freon it uses.
