If they sold you a service contract there is a written agreement, demand a copy. If there is a parts warranty on your ac unit it also is in writing, demand a copy. The parts warranty with your ac unit probably was delivered at the time the unit was installed. However, warranties are very specific to their terms and usually verbal statements about what is or is not covered are not sufficient to overcome what is in the warranty. It would be a very unusual circumstance to have a verbal warranty with no writing.
