Call Journey Home Inspections for all of your North Texas Home Inspection needs 817-296-8443! As a Home Inspector we check out the homes air conditioner pretty thoroughly. Here’s a few tips of things that you can do to help maintain the unit! 

Monthly rinse out the outside unit with a garden hose. This will allow it to work more effectively. 
Be sure the suction or cool line from the condenser to the compressor is insulated with snap-on urethane or other high R-value insulation.
Don’t be afraid to monthly take a garden hose and spray out your outside unit really well. This will help it cool and work more efficiently. 

Straighten all of the evaporator and condenser coil fins with a small pointed stick or a special plastic fin comb. Bent fins do not allow proper air distribution.
If the condenser is at ground level, be sure no vegetation or foreign material is restricting the air flow path. If possible, shade the condenser with trees or bushes, which will improve the cooling efficiency by elimination of direct sunshine.
