Hi, all. We have a condo at the beach, and the heat pump condenser unit on the rooftop needs replacing. I am told that in 2020, the rules are that these units will need to use a new type of freon, 410A. And that as of 2010, they will stop making the units that work on R22, current type of freon.
Several places we have contacted have told us that at this point, it is fine to just go with units that use the current type of freon, R22. Especially since we are not able to afford replacing our 2-ton HVAC unit, which is about 18 years old. He says that that unit has lots of life left in it, cause it's easy to replace the fan motor.
We are looking at an American Standard heat pump condenser right now, which is the best price. Other companies have told us they use a heat pump condenser that has a "special coating" to guard against salt air. The American Standard guy says that while his doesn't have a special coating, it is made with the same type of metal inside (as opposed to kind made with two different ones, which could lead to rusting).
What I need to know is: 1) whether it's fine advice to go with a unit that works on R22. And 2) whether it's OK to get a unit without special coating to guard against salt air. THANK YOU for any opinions.
