I have a 37 yr old air conditioning unit that has borke down each summer. I have tried not to file a complaint but see if I could get it fixed. This year, I finally filed a complaint. Becasue of a dirty air filter, they are saying it is a lack of maintainence and not due to the unit being 37 years old. The whole reson I bought the warranty 2 or 3 yrs ago was becasue the unit is so old. I cannot control what happened before I bought the house and if they were not going to cover it, they shouldn't have sold me the warranty. They are a joke and I am telling anyone and everyone who asks that they are ridiculous! I am getting a second opinion today that is independant and contacting a lawyer!
