Visual Inspection

After testing your thermostat, a visual inspection of the exterior and interior components of the air conditioning system is performed to identify obvious signs of damage or wear. During this phase of the maintenance visit, an HVAC tech will also inspect electrical terminals and check for loose connections. Any necessary repairs are made, and electrical circuits are tested to ensure they’re all working properly and not consuming more power than necessary.

Refrigerant Levels

Checking refrigerant levels are a large part of A/C maintenance and service. A qualified technician should check the levels and adjust if necessary to ensure your system isn’t working harder than it should to cool your space. If the level is significantly lower than it should be, this stage may become more involved to determine the cause and repair the leak if it is minor.


There are many moving parts inside the air conditioning system that work to cool and distribute air throughout your home. Lubricating all moving parts keeps them operating smoothly and helps extend their life span. Since friction is reduced when parts are properly lubricated, this step also helps prevent overheating.


Finally, a careful inspection and cleaning of the condensation drain in your system is performed. If there are any blockages, they’re cleared and the area is inspected to ensure you won’t suffer a water leak.
