The warm days of spring are fast approaching. It is time to slowly turn off your furnace and start preparing your air conditioner for the cooling season. You do not want to find out on the first warm day of the year that your AC is damaged beyond repair. To make sure you can rely on your cooling system this spring, you should complete this AC inspection checklist.

Here are the critical parts of your air conditioner that you need to check before running the system.

Outdoor unit:


The outdoor unit panels are designed to protect the electrical connections from heavy weather damage. If a panel is misaligned or missing, this can be dangerous for you and your HVAC equipment. Before you turn on your air conditioner, be sure to call a qualified contractor to do a unit assessment first.


The system coils play a vital role in keeping your indoors cool and comfortable. The outdoor coil or condensing coil facilitates heat transfer to the outdoor air. Once dirt or vegetation is blown into the coil, it will not be able to perform its function well. To allow good airflow to the outdoor unit, you should clean the unit and its surrounding area.

Suction line

The suction line is one of the two refrigerant lines that connect the outdoor unit to the indoor evaporator coil. It carries cool gas and has to be properly insulated. During winter, the pipe’s foam insulation can easily wear out. Failure to repair or replace the damaged pipe insulation can negatively affect the operation of your cooling system.

Indoor unit:

Air filter

After checking your outdoor unit, turn your attention to your AC indoor unit. Among the first things you need to check is the condition of your air filters. Your AC air filters clean the air that circulates through the system by trapping particles and contaminants. Dirty and clogged filters can cause your air conditioner to blow warm air. It can also trigger allergic reactions in some people or members of your family. To prepare your AC for the cooling season, do not forget to clean your air filters or replace them if necessary.

Supply vent and air return grill

Dust and dirt may have accumulated on your supply vents and air return grills during the previous season. Get rid of these obstructions right away to allow smooth and proper airflow back through the system. Failure to do so can cause severe damage to your HVAC unit. Experts recommend cleaning all grills at the beginning of every season.
