Summer is just around the corner, and with the rising temperatures, keeping your home cool becomes a top priority. Your air conditioning (AC) unit is the hero that ensures your comfort during those scorching hot months. However, in order for your AC to perform at its best, it needs some TLC before the summer heat hits.

Just like any other major home appliance, your air conditioner needs regular maintenance to function efficiently. A little bit of preparation can extend the life of your AC, save you money on energy bills, and prevent breakdowns in the middle of a heatwave. We’ll walk you through the steps for AC Preparation for the summer heat, ensuring that it’s ready to keep your home cool all season long.

1. Clean the AC’s Air Filters

Over time, they become clogged, reducing airflow and increasing energy consumption. Clean or replace filters every 1-3 months.

How to Clean or Replace the Filters:

  • Locate the filter behind the return air grille.
  • Remove the filter and check its condition.
  • Clean reusable filters or replace disposable ones.
  • Reinstall snugly in the housing.

2. Clean the AC Coils

Dirt on evaporator and condenser coils reduces efficiency and can cause breakdowns.

How to Clean the Coils:

  • Turn off the power to the AC unit.
  • Clean evaporator coils with a brush or compressed air.
  • Rinse condenser coils gently with a hose.

3. Check the Refrigerant Levels

Low refrigerant affects cooling and may cause damage. If your AC isn’t cooling properly, contact a professional to check and refill refrigerant.

4. Inspect the Ductwork

Leaky or blocked ducts reduce efficiency and airflow.

How to Inspect Your Ducts:

  • Check visible duct sections for damage or loose connections.
  • Watch for uneven room temperatures.
  • Hire professionals to seal and insulate ducts.

5. Clean the Condensate Drain

Clogged drains can cause water damage or flooding.

How to Clean the Drain:

  • Locate the drain near the bottom of the indoor unit.
  • Use a wet/dry vacuum to remove debris.
  • Flush with water and vinegar to clear buildup.

6. Check the Thermostat

A malfunctioning thermostat can lead to inefficient cooling.

How to Check:

  • Set to a lower temperature and observe if the AC turns on.
  • Compare with a separate thermometer.
  • Upgrade to a smart thermostat for better control and efficiency.

7. Ensure Proper Airflow Around the Outdoor Unit

Obstructions reduce efficiency and increase strain on your AC.

Tips:

  • Clear debris and trim vegetation near the unit.
  • Ensure several feet of clearance around the unit.

8. Schedule Professional Maintenance

A professional HVAC technician can catch issues you might miss.

Benefits:

  • Comprehensive inspection and tune-up.
  • Preventive care to avoid breakdowns.
  • Improved energy efficiency.

9. Upgrade Your AC (If Needed)

If your AC is over 10 years old or frequently needs repairs, consider replacing it.

Signs It’s Time:

  • Frequent repairs and inefficiency.
  • Increased energy bills.
  • Ineffective cooling.

Exterior parts are essential to overall performance.

Tips:

  • Clean condenser coils regularly.
  • Inspect for wear, rust, or leaks.
  • Check insulation on refrigerant lines.
