    I have an ocean front condo with a 1.5 ton Lennox heat pump that is 7 years old. The outside unit's fins are crumbling when touched. I'm looking for advice on what unit would last the longest in a harsh environment. I've heard about phenolic coated units but Lewnnox's web site doesn't mention this.

    Any particular brand/model to consider?

    Thanks,
    Dave

    In my experience Trane's spine fin coils seem to stand up particularly well in salt air environments.

    i do a lot of work along the ocean front in jersey and have found there is no beter then a another here. seems all brands tend the deterate over 5 to ten years. the closer to the ocean front the faster it would seem.
    i dont know where you live but to give a certain brand and say it will out last any other i cant do. i have found turn off all breaker to kill any power to the unit put a coat of car wax on the casing and hose off the coil a coupletimes a year hepls it to last longer. after an hour turn the breakers back on. the wax will protect the casing and washing the salt and sand out of the coil will slow down the deterating process

    Trane/American Standard Spinefin will stand up the best.

    Many coatings out there that will extend the life of coils with copper tubes and aluminum fins, but in my opinion they will still fail, before a spinefin ever would.

    Or install a sacrificial Goodman, and replace it every 5 years.

    Maybe Goodman will listen to Robo and use the black paint again. The painted ones did surprisingly well.

    Washing the coils frequently helps. Do not use a pressure washer, especially on a coated coil.

    I agree with the Trane spine fin coil. You can also purchase a 10 year parts and labor warranty. That way you have "peace of mind".

    Last time I checked the warranty is an extra $100 (plus the regular cost) if within 5 miles of saltwater.

    Good luck.

    I live in eastern NC.

    Searching for "broze glow" and "bronze glow" on google didn't turn any coil coaters up.

    I have been advised to clean with water and then spray a teflon based lubricant spray over the fins. Sound or bad advice??

    What kind of premium does the extra coating run? Will the SEER be better if I wait until early 2006?

    Having worked with Carnak on units that were extensively exposed to super salty conditions I have to agree that the Trane-A/S spline fin coils held up better then coated coils.

    As far why the black painted Goodman coils held up so well, I don't think it has anything to do with the black latex paint that was only sprayed on the outside of those coils. The unpainted Goodman coils are also holding up.

    My only guesses are that either the nonevaporative oil that Goodman alone must use during processing of their coils gives protection against salt air or there is something in the copper to aluminum fin process that retards the reaction that causes the deterioration.

    I have a friend in Galveston, Texas that swears by Cal-Shield. He sprays it on his customers indoor and outdoor coils every year when he does maintenance.

    If more government is the answer, then it's a really stupid question.

    Sure do. These photos are of a chiller coil that has been treated with BronzeGlo. The only sign of deterioration is where BronzeGlo did whatever they do to create a shadow of their name http://www.roboteq.info/bronzeGlow.html?1121653186692
