I have a Ocean front property in Mexico. The unit is on the top of the build and the salt aire has eaten both my 3 ton york units alive in just 5 years. The units only get used once a month for a couple days in the summer and heat in the winter.
Is there any A'C units that are better equipped to handle the harsh sea environment? The A/C dealer down there wants to put in 2 new 13 seer tranes... Is there something better ?
