Keeping Your AC System in Top Shape: 5 Essential Maintenance Tips

August 7, 2023

As the summer heat arrives, having a properly functioning air conditioner is crucial for maintaining a comfortable home environment. Your air conditioner is one of the most vital appliances, working tirelessly to provide cool relief during the sweltering summer months. However, like any complex machine, central air conditioning systems require regular maintenance and care to operate optimally. To keep your AC unit running smoothly all season long, follow these five essential tips for preventative maintenance. Keep reading to learn pro tips to maximize your AC system's performance and longevity this summer.

Air conditioner maintenance

1. Change Air Filters Frequently

Air filters play a crucial role in your AC system by trapping dust, dirt, pollen, and other particles from circulating through your home. As these filters become clogged, airflow is restricted, forcing your AC to work harder. This leads to higher energy bills, decreased efficiency, and possible system failure. Filters should be changed every 30-90 days during peak usage seasons for optimal performance. Using electrostatic or pleated media filters can extend the replacement timeframe while still maintaining air purity. AC repair plantation specialists recommend checking your filter each month and replacing it if dirty. Mark your calendar to remind yourself since filters are often out of sight and out of mind. An obstructed filter will also cause indoor air quality issues, allowing contaminants to build up inside the ductwork.

2. Schedule Professional Tune-Ups Annually

While you can perform some basic maintenance yourself, a certified technician should inspect your HVAC system at least once a year. A comprehensive tune-up and cleaning will maximize performance and detect any parts needing repair or replacement. The technician will check refrigerant levels, belts, motors and fans, coils, drains, air vents, thermostat calibration, and overall operation. Minor issues will be corrected to restore your AC to factory fresh condition. Think of seasonal tune-ups as preventative medicine for your system. Schedule tune-ups in early spring to proactively prepare for the upcoming summer heat. Technicians offer discounts during off-peak seasons and have more availability in their schedules. Your AC will be ready to handle the harsh summer temperatures without missing a beat.

3. Clear Debris from Outdoor Unit

Take a few minutes each month to survey the outdoor condenser unit. Remove any leaves, grass clippings, or other debris accumulated around the metal casing. Keep plants and shrubbery trimmed at least 2 feet from the unit. Anything obstructing airflow will force the condenser to work harder to release heat. Also, check that the unit is level and stable. Settling soil or landscaping can cause tilting over time. Use metal shims to level it if needed. Ensure the base sits above the ground on a concrete pad, cinder blocks, or brick pavers. This allows proper drainage and air circulation.

4. Check Refrigerant Levels

The refrigerant is the lifeblood of your AC system, circulating to remove heat and moisture from your home's air. Over time, refrigerant levels may drop due to leaks in seals or coils. Low refrigerant will degrade your AC's capacity to cool your home properly. Warning signs include higher electric bills, failure to reach the set temperature, and short cycling on and off. Only certified HVAC technicians have the equipment to check the pressure and confirm if refrigerant levels need to be restored. Refrigerant is a sealed, regulated system, so do not attempt DIY charging. Prevent leaks by replacing worn parts and coils when recommended. Properly maintained, most AC systems should not leak under normal conditions.

5. Replace the Ceiling Fan Directional Switch

Here is an easy DIY maintenance task - check that the directional switch is functioning properly on any ceiling fans paired with your central AC system. During the summer, the blades should spin counterclockwise to push cool air downward and maintain comfort. If the fan is spinning clockwise, reverse the directional switch and listen for a click. The slight airflow created by fans makes your AC's job easier. Also, dust and clean fan blades that collect dust and allergens. Replace any cracked or warped blades that are out of balance.

Final Thoughts:

Keeping your air conditioner in peak operating condition requires dedicating time each season to essential maintenance tasks. But the effort pays dividends when it comes to your AC system's performance, energy efficiency, and longevity. By routinely replacing air filters, cleaning condenser coils, inspecting ductwork, trimming vegetation around outdoor units, and scheduling preventative HVAC maintenance checks, you can keep your air conditioner running like new year after year. Proper maintenance extends the lifespan and efficiency of your home's air conditioning system and saves you money on energy costs and repairs over time.
