Air Conditioning Maintenance & Inspections

During your air conditioning maintenance appointment, several important tasks will be performed to ensure the proper functioning and efficiency of the system. These tasks guarantee that your air conditioning system will consume as little electricity and will last as long as possible. At the beginning of every A/C maintenance appointment, the air filter is inspected and replaced if necessary to improve air quality and prevent blockages. Second, the evaporator and condenser coils are inspected and, if needed, cleaned to prevent dirt and debris buildup, which can cause reduced airflow and energy consumption. Also, the drain line will be checked for clogs and cleared if necessary to prevent water damage and mold growth. Additionally, the refrigerant levels will be checked and adjusted if needed to ensure optimal cooling performance. Finally, the overall system will be inspected for any signs of wear or damage and repaired as necessary to prevent further problems. Regular air conditioning maintenance can extend the lifespan of the system and save energy and repair costs over the life of your unit. 

When should A/C maintenance be done?

Air conditioning maintenance should be performed at least once a year, ideally before the start of the cooling season. It's recommended to have the maintenance done in the spring, before the hot summer months when the air conditioner will be used the most. However, depending on the usage and condition of the AC system, it may require more frequent maintenance. For example, if the AC is used heavily or in a damp environment, it may need maintenance more often. It's important to have the system checked regularly to prevent breakdowns, extend the lifespan of the unit, and ensure that it's running efficiently.

My cooling system is new, does it still need yearly maintenance?

Yes! It's important to inspect all systems, even new ones, to ensure the install was done correctly and all manufacturers require yearly maintenance to ensure the systems warranty will be honored in the case of a breakdown. Also, small problems that are caught during an A/C maintenance or A/C inspection can be fixed so larger more expensive problems can be avoided.
