Annual HVAC maintenance is essential to improving efficiency and prolonging the life of your system. There are certain fundamental service tasks your cooling technician should do on a service call in the spring:
Check the evaporator and condenser coils.
Test the refrigerant levels and ensure there are no leaks.
Inspect the blower and test its airflow.
Make sure that the thermostat operates correctly.
Inspect all of the moving parts in the system, lubricating as necessary to help avoid wear and tear caused by friction.
Check the condensate drain, ensuring that condensation can properly exit the system, and checking for clogs throughout the drain.
Test the system controls, making sure that the heat is locked out when in cooling mode, and vice versa, and ensuring that the A/C equipment cycles on and off correctly.
A simple task that homeowners should do to ensure peak performance from their air conditioners is to make sure to change the air filter regularly. When you run your A/C frequently, check it once a month and change it when it looks dirty.
All of these maintenance tasks will keep your system in good working order, but you can benefit even further by participating in a Shumate service agreement.
