Once a year is good! Coil cleaner is best and rinsing afterwards from the inside out. More photos to follow. This is a before one.

Hey Brent! We are in Michigan and we schedule for every other year for most units but some are in areas that require annual clean outs.

it should be annual to keep it breathing good

Yearly, coil cleaner and hose.

For ours, we try to keep it simple and make it part of the regular HVAC maintenance routine. We first switch off power to the condenser, then remove leaves, grass, dust, and other debris around the unit. For the exterior fins/grilles, we use a soft brush or a gentle stream of water to loosen buildup without bending the fins.For properties where there’s a lot to stay on top of, InstaService can also be useful for getting routine HVAC and home maintenance tasks handled by a local professional, rather than letting small maintenance jobs pile up.As for frequency, I’d say at least once or twice a year, with additional cleaning when the unit is in a particularly dusty area or surrounded by trees. During spring and summer, I also like to do a quick visual check for leaves, grass clippings, dirt, or anything restricting airflow.One thing that makes a noticeable difference is keeping the area around the condenser clear-not just cleaning the grille itself. Restricted airflow can make the system work harder and affect cooling performance. For larger properties or multifamily buildings, having the units checked as part of scheduled HVAC maintenance is probably the easiest way to stay on top of it.
