Keeping your air conditioning system well-maintained is the key to staying comfortable during Los Angeles’ extended hot seasons. A properly serviced AC runs more efficiently, experiences fewer breakdowns, and often lasts significantly longer than a system that’s neglected. At Air Plus HVAC, Inc., we believe in the power of preventative maintenance, and we’ve developed this seasonal AC checklist to help you stay ahead of issues and enjoy reliable cooling all year long.

Spring: Prepare for Peak Cooling Season
Spring is the ideal time to get your AC system ready for the months ahead. Begin by replacing your air filter to improve airflow and indoor air quality. Take a moment to test your thermostat, ensuring it’s operating correctly. If you haven’t already, consider upgrading to a programmable or smart thermostat for enhanced comfort and energy control.
Next, inspect your outdoor condenser unit. Clear away any leaves, dirt, or other debris that may have built up around it. Make sure the unit has at least two feet of open space on all sides for proper ventilation. Check the refrigerant lines for worn or damaged insulation. You should also turn the system on briefly to test its performance. Listen for unusual noises and check that the airflow feels strong and cool.
Most importantly, schedule a professional spring tune-up with Air Plus HVAC, Inc. Our experienced technicians will perform a thorough system inspection, clean the condenser coils, verify refrigerant levels, tighten electrical connections, and make sure everything is in peak condition before summer arrives.
Summer: Monitor System Performance
As your AC works its hardest during the summer, it’s essential to monitor its performance. Replace the air filter monthly if your system runs continuously. Stay alert for early warning signs such as uneven cooling, unexpected spikes in energy bills, or strange noises that may indicate a developing issue. Also, be sure to keep the area around your outdoor unit clear and avoid setting the thermostat too low, which can lead to unnecessary strain on the system.
If you notice any changes in performance, don’t wait. Contact Air Plus HVAC, Inc. as soon as possible. Catching and fixing a minor problem early can help you avoid costly repairs and extended downtime during the hottest part of the year.
Fall: Shut Down and Inspect
Once the intense heat of summer begins to ease, reduce your AC usage and prepare it for the off-season. Change the air filter one more time and double-check your thermostat settings. Protect your outdoor condenser by covering it with a breathable, weather-resistant cover to shield it from dirt and debris over the winter months.
Fall is also a great time to assess your ductwork. Look for visible signs of leaks, mold, or poor insulation. If you’ve experienced uneven airflow during the summer, now is the time to consider duct cleaning or sealing to improve overall system performance before the next season begins.
Winter: Off-Season Maintenance Prep
Even though your AC might not be in use during Los Angeles’ mild winter months, this is the perfect time to plan ahead. Use the season to research system upgrades or schedule a consultation if your unit is aging or showing signs of inefficiency. If your home uses a heat pump, which provides both heating and cooling, winter maintenance is especially important to keep it operating smoothly year-round.
