I have worked in the hvac field for about 5 years now. I do have a couple of questions for you.....Are you having your units seasonally maintenanced? Are you changing the filter at least every 30 days? Is your supply located near your puppies?
I just wonder these questions first because #1 if your not having them seasonally maintenanced then the coils will become corroded FAST.....#2 You have to change the filter at least every 30 days because otherwise you are blocking air flow and therefore making the machine work a lot harder. And #3 if your supply is located near the puppies it is possible for the acid to be being pulled in right on top of your coils.
I worked for the American Standard brand for about 4 years, really and truly they are the best. Consumer Reports has had it listed #1 for least amount of problems for many years.
Let me know about the questions listed above and I will see if I can be of anymore help!
