We have used Opie's for many years now. We have never had a bad experience. Every time we have to call and/or they come to our house they are always friendly, kind, and courteous. Easy to work with and very helpful and informative.
Sometimes even going above and beyond the heating and cooling part to help with other things such as killing a wasp that made its way in, so no one would get stung!
The service is always great and we always enjoy working with them.
