By becoming a Preventive Maintenance Agreement (PMA) customer you will be placed on a maintenance schedule in our computer systems. You may choose an annual service, a semi-annual service, or more frequent services throughout the year. We will call you to let you know when it is time to service your heating and cooling system. You will not have to worry about a thing, we will take care of everything. You will be entitled to a 10% discount on services, including parts and labor. You will also receive the same low rate for services conducted after hours, on weekends, and holidays. The cost to become a PMA customer is FREE and will cover you for a lifetime.
