I worked in Daytona Beach area for a few years and those coast gaurd units did okay but for in the differance in price id just buy a goodman or something else. The maytag did okay out there, they usually lasted for atleast 7 to 8 years, but we would coat the coils with a special coating to protect them better. Ive been to plenty of homes where the coils are shot in as little as 3 years and i hate telling the cust they are going to have to cut us another check for new cond. unit!
Oh, c'mon, dog piss wins ever time. Only a little "extra" 120v/220v current running through the chassis stands a chance against that.

Even without spines, they'll still run quite well (hopefully they oversized 'em slightly to compensate for the coastal environment).
sheesh........a little pm and they should be fine........ Im close (<2 miles) from the pacific, so yeah, I have seen that movie!
you was right.Ive never seen anything like that

Trane Whats the coil look like ?
Trane
I have this one It took 14 years to get that bad though, still working
Trane Do you have any pics of tranes or american standards that are shot from the salt ? Thanks

Swampfox, When I lived in FL I sold a lot of air cooled condensers to Winn Dixie, Patrick AFB and a few others that were coated with a product called Adsil. http://www.adsil.com/products/hvac.htm They use factory authorized HVAC contractors to apply their product. Check it out, maybe you can make a few extra bucks as a Adsil contractor. Of course my standard 10% commission will apply.

Check with your distributer if you have doubts, but that is the recommended cleaning method.

I've been fortunate enough to find other chases to run new linesets down, but I know this won't always be the case. We do alot of them here, we have to get access to every condo in the stack(linesets run up through each ahu closet) between the unit in question and the roof and use a tripod on the roof with a come-along on to pull new lineset through using the old lineset. Most of the time the leak is close to the top and we only pull through what we need to. On the condos that use the through the wall type condenser on the rear patio, we have to pull the new lineset through the duct from front to rear(60 ft), exit the trunkline(ductboard) next to the last register ,go across and down the bedroom wall with acr, drill through the concrete block to where the condenser sits on the back patio. The HO then has to have crown molding installed in the bedroom to cover the linset/wiring. These are a real PITA because the trunkline doesn't go straight through, there are a few turns. It usually takes 2 guys about 10-12 hours to do.
I work in costal SC. We spray ALL our warranty coils before they go out. We even sell condensers sprayed entirely in heresite for ocean front houses. I don't think it's ever enough because the spray can't get everywhere. Has anyone used "Corrosion Grenades"? They are a zinc ball which you attach near the coil. The zinc is supposed to act as an anode, but the surface area versus the coil seems much too small to me.
is this a .0000005 seer?
Yup luckly this is a fist floor job with a drop ceiling so it wont be bad.We are going to insulate the liguid line to protect it.Also using liguid tight for the electrical and the control wires.The house is 30 years old in good shape.The last time this was replaced it was done by a family friend so he did it on the cheap and cut many corners.Now its my turn to make it right.Should have it done in one day.
