A properly sealed AC system should not need refrigerant added. Refrigerant does not get consumed through normal use the way oil or fuel does. If your system requires a recharge, that is a sign there is a leak somewhere in the system. Recharging without finding and repairing the leak will result in the same problem returning within months. If your AC has gradually become less effective over several years with no obvious leak symptoms, a small amount of natural permeation through seals can be addressed, but the system should still be inspected first.

Running the AC briefly during the winter months, even when it is cold outside, is actually good for the system. It keeps the compressor seals lubricated and prevents refrigerant from migrating to areas it should not be. Many vehicles automatically engage the AC compressor when the defrost mode is selected, so you may already be doing this without realizing it. Running it periodically through the colder months also gives you an early warning if something has gone wrong before you need it during summer heat.

The cabin air filter cleans the air that flows through your vehicle's HVAC system before it reaches the passenger compartment, filtering out dust, pollen, mold spores, and other particles. A clogged cabin air filter reduces airflow from the vents, makes the AC and heater less effective, and can worsen air quality inside the car. Most manufacturers recommend replacing it every 15,000 to 25,000 miles, or annually. If you drive frequently on dusty roads or suffer from allergies, more frequent replacement is worthwhile.
