Corrosion resistance compressors for the Beach House?

[davidshammer]

Hello all, I'm a contractor in Atlanta that is working on a Beach House at Tybee Island,GA. I'm remodeling the house and raising the roof for a second story and deck to see the ocean. I have noticed that anything metal will rust on this island. I have to install fiberglass doors as metal ones rust in 3 years! Does anyone in the field know of any makers or types of compressors that are made for beach side houses? Also, I would like to have a 2 zone system for the house. The upstairs is about 500 sf. The 1st floor being 1700 sf. Thank you for your help in this matter.

Hey, thanks alot!

Just throw in a Goodman and plan on replacing it in 5 years...

Trane or Goodman ... Trane is built like a tank and ya can't rust aluminum fins..... Goodman is cheap enough to replace all the time.

Just saw my first Maytag condensing unit last week.. stainless steel cabinet ...very nice looking unit.....I live and work here on the southeast coast...tranes dont hold up so well as they'd have you believe. Salt air really raises havoc with anything aluminum or copper.

IMHO nothing stands up better to salt than the Trane/AS aluminum spine fin.

Or put in a sacrificial Goodman.

Regular coil washing makes a difference on copper tubes with aluminum fins.

The only way to get rust proof AC is open the vinyl windows you are going to install. There! no worries about rust

I have had experience with this with a condo at Gulf Shores, AL. We had aTrane rooftop unit right on the Gulf that lasted over 15 years because of the aluminum spine fin coil. Most people do just sacrifice a Goodman every 4 years or so.

never had much faith in carrier's coastal construction.

I am in a severe salt environment and the coils that stand up the best is the Trane/AS/old GE Spinefin. Casings could rot but coil is fine.

Search a guy called swampfox, he sees a lot of coastal stuff, and most of these places are up on stilts. They put the condensers under neath the places. He has an observation/conclusion about these units that makes sense to me. When they are under the places on stilts, they are sheltered from the rain. So with rain, you get nature helping you to wash the salt away.

Condensers that are regularly washed seem to last longer.

So it is either Trane, a lot of preventative meaintenance, or slap in a builder's model and deem it disposable.

I do not have much faith in field applied coatings, factory applied coatings are a little better than nothing.

York claims that their microchannel coil is doing well in the salt spray.

carrier corosion units hold up well

IMO just get any brand and insist on a corrosion gernade installed on it
these little zinc work well and as long as the unit is washed down it will hold up

For you guys buying those "corrosion grenades", google zinc anodes. Exact thing, repackaged. Most marine supply houses have them.
The Under deck thing holds true for most units out there. I have tried and just given up on having people rinse these units regularly.
