Do you have a membership in a service club for your heating/ac unit?
The folks that I use for maintenance on my heat pump/ac unit have a service club membership with different levels of membership. You pay a monthly fee and the club provides free services, discounts on repairs, guaranteeing appointments within a certain period of time, and guaranteeing their work. Membership classifies you as a preferred customer.
Just wondering if anyone has this kind of membership and whether they thought it was worth the money.
