Maintenance and Service
 
A central air conditioning is not a household appliance.

It’s a self-contained system that requires professional maintenance and repair.

That’s why attempts at “do-it-yourself” repairs on an in-warranty unit may void the remainder of your warranty.

Other than performing the simple maintenance recommended in here, you should not attempt to make any adjustments to your central air conditioning system.

Preventive Maintenance Agreement
 
Preventive maintenance agreements (PMAs) are agreements between you and Maryland Air Conditioning and Heating, LLC. for scheduled inspections and maintenance of your heating, ventilation, and air conditioning (HVAC) system.

PMAs are generally scheduled semi-annually to maintain peak efficiency, prevent utility overpayment, and avert system failures through predictive maintenance that can help extend the life of your HVAC system.
