Preventative Maintenance Program

Our Heating and Cooling Preventative Maintenance Program is Accepting New Members.

You don’t have to work long in the HVAC business to learn that homeowners hate surprise repairs or, worse, replacements for their heating and cooling system. At Morelli Heating & Air Conditioning, we know how frustrating these HVAC surprises can be – and we know that regular preventative maintenance is the best way to avoid repairs and replacement due to wear and tear or small issues that grow into larger ones.

But not all homeowners have the time or the know-how for quality preventative maintenance. That’s why we created the Morelli preventative maintenance program – a preventative maintenance and discounted service subscription, and our way to ensure you’re prepared for the hot and humid summers of South Carolina and for the winter season. Preventative maintenance in the spring and fall reduces any surprises when you need your heating and cooling systems the most.


 Our preventative maintenance program does not discriminate based on your system, either. Though we’re a Factory Authorized Dealer of the Carrier line at Morelli, we service all makes and models. In fact, our NATE certified technicians go through rigorous training to ensure their knowledge base is broad for all types of equipment.

The cost of a maintenance agreement is dependent on the number of systems in your home and the contract terms. The typical agreement is for two visits, one heating and one cooling, per home. It’s also common for customers to sign up for a one year plan and renew with us yearly.

You’ll see us in the spring to tune up your cooling system and the fall to check on your heating system. Our friendly office coordinators will help you set up a visit at the most convenient time for you. We promise to be respectful in your home or business. What else would you expect from a company who abides by the golden rule?
