Blazing pavement and relentless humidity can cause your car's air conditioning system to work overtime just to keep the cabin comfortable.While it may be tempting to crank the AC to its coldest setting the moment you climb inside, a few simple practices can actually help the system cool your car faster while reducing wear and tear. Whether you're heading to the grocery store or setting off on a road trip, these easy maintenance tips can help your car's air conditioner stay in top shape all summer long.Let The Hot Air Escape FirstWhen a car has been sitting in the sun, the interior can easily climb well above 130℉. Instead of immediately asking your air conditioner to cool that trapped heat, open the doors or roll down the windows for about 30 seconds before driving away.AdvertisementAdvertisementOnce you're moving, keep the windows cracked briefly while running the AC. This allows much of the superheated air to escape, reducing the work your air conditioner has to do and helping the cabin cool down more quickly.Your air conditioner works best when it doesn't have to fight extreme interior temperatures. Whenever possible, park in the shade, use a windshield sunshade, or cover the dashboard to reduce heat buildup. Start With Fresh AirMany drivers immediately press the recirculation button, but that isn't always the fastest way to cool a scorching cabin. When you first turn on the air conditioner, use the fresh-air setting for a minute or two to push out the hottest air. Once the cabin begins cooling, switch to recirculation mode. At that point, the system is cooling already-conditioned air rather than continually drawing in hot outdoor air, making it more efficient.Routine Maintenance Goes A Long WayRegular summer vehicle maintenance is key. Keeping coolant levels topped off, checking belts and hoses, and ensuring your engine isn't overheating all contribute to overall performance, including the air conditioning system.

A dirty or clogged filter restricts airflow, forcing the system to work harder while delivering weaker airflow through the vents. If you've noticed reduced cooling or musty odors, a fresh filter may make a noticeable difference.If your air conditioner suddenly isn't blowing as cold as it used to, don't assume it will fix itself. Warm air, unusual noises, unpleasant smells, or inconsistent cooling could point to low refrigerant, a leak, a worn compressor, or another mechanical issue. Addressing problems early often prevents more expensive repairs later, especially before the hottest stretch of summer arrives.Give Your AC A Workout Year-RoundAlthough it may seem counterintuitive, try running your air conditioner for a few minutes every couple of weeks, even during the cooler months. Doing so helps lubricate seals and keeps refrigerant circulating through the system, reducing the chance that components dry out during long periods of inactivity. By the time summer returns, your air conditioner is more likely to be ready for the season's hottest days.Read the original article on Southern Living
