HVAC maintenance typically includes a range of tasks that are designed to keep your heating and cooling system functioning at its best. Some of the common services included in HVAC maintenance are:

Cleaning of the system components: This includes cleaning the air filters, condenser coils, and other parts of the system that can become clogged with dirt and dust.

Inspection of electrical components: Technicians will inspect the wiring, controls, and other electrical components to ensure they are functioning correctly and are not a potential safety hazard.

Testing of system performance: Technicians will run tests to evaluate the efficiency and performance of your HVAC system to ensure it is operating at peak capacity.

Lubrication of moving parts: Technicians will lubricate the moving parts of your HVAC system, such as the motors and fan blades, to reduce friction and extend the life of the system.

Refrigerant level checks: Technicians will check the level of refrigerant in your cooling system to ensure it is at the correct level, and make any necessary adjustments.

Inspection of ductwork: Technicians will inspect the ductwork for signs of leaks, damage, or clogs, and make repairs as needed.

These are just some of the common tasks included in HVAC maintenance, and the specific services included may vary depending on the type of system you have and the services offered by your maintenance provider.
