Tuning up your air conditioner is easy--tips for how to learn how

When summer temperatures rise, a well-functioning air conditioning system is a must. Keeping your AC in top condition keeps your home comfortably cool, lowers energy bills, and extends your AC's lifespan. Simple air conditioner maintenance—both DIY and professional—keeps your AC running efficiently and effectively all summer.

KEY TAKEAWAYS

  • Regular AC tune-ups improve efficiency and lower energy costs.
  • Routinely changing the air filter prevents costly repairs.
  • Monitoring your AC helps identify issues early and avoid breakdowns.

Air conditioners need regular care to function at their best. Whether your unit is brand new or has been cooling your home for years, performing a simple yearly AC tune-up helps keep your unit in shape. This routine can lower energy consumption and help avoid costly repairs.

1. Replace the AC Air Filter

A dirty air filter restricts airflow, forcing your air conditioner to work harder and increasing energy use and utility bills. A clogged filter can also cause refrigerant issues, which may damage the compressor and lead to costly repairs. To keep your air conditioner running smoothly, the Environmental Protection Agency’s Energy Star program recommends checking the air filter monthly, especially during peak usage, and replacing it every one to three months.

2. Schedule an Air Conditioner Tune-Up

Scheduling a professional AC tune-up keeps your air conditioner in top shape. Regular check-ups by skilled technicians help your system run efficiently, reduce the risk of breakdowns, and extend its lifespan. Here’s what a professional AC tune-up typically includes:

  • Adjusting Thermostat Settings: Fine-tuning your thermostat to match your daily schedule and comfort preferences can boost energy efficiency and improve overall comfort.

  • Cleaning Coils and Components: Removing dirt and debris from coils, ducts, and blower parts enhances airflow and increases the system's efficiency, which can lower energy costs and improve cooling.

  • Checking Refrigerant Levels: Proper refrigerant levels are crucial for effective cooling. Technicians check these levels and make adjustments to maintain optimal performance.

  • Inspecting Electrical Connections: Making sure all electrical components are functioning properly improves both safety and efficiency.

  • Examining the Condensate Drain: A clogged condensate drain can cause water damage and increase humidity levels. A thorough inspection and cleaning of this drain prevents such issues.

A yearly AC tune-up helps maintain comfort and efficiency, keeping your home cool during hot summer months while saving money by preventing costly repairs and optimizing your system’s performance.

3. Monitor Your AC's Performance

Regularly checking your air conditioner’s performance helps keep your system running smoothly. Pay attention to these key areas to ensure your AC is operating efficiently:

  • Cooling Effectiveness: Check if your AC is cooling your home as expected. If the air feels warm or the temperature isn't dropping, there might be an issue.

  • Unusual Sounds: Listen for any strange noises, such as rattling, buzzing, or grinding. These sounds could indicate problems with the compressor or other components.

  • Airflow Issues: Notice if there's a lack of airflow from the vents. This could be a sign of a clogged filter, blocked ductwork, or a failing blower motor.

  • Moisture or Leaks: Look for moisture around the indoor unit or any visible leaks. These could point to a blocked condensate drain or a refrigerant leak, both of which need immediate attention.

Addressing these signs early can prevent minor issues from becoming major problems. For instance, moisture around the unit might suggest a blocked drain or refrigerant leak, which can cause severe damage if ignored. Unusual noises might mean the compressor is struggling or parts are loose. Prompt professional AC help can prevent a small problem from turning into a costly repair. Regular monitoring and quick action help keep your AC running efficiently and your home comfortable all summer long.

4. Consider Replacing an Older AC

Modern air conditioners use much less energy than older models. According to the U.S. Department of Energy (DOE), today’s best units consume 30% to 50% less energy than those made in the mid-’70s. Even if your AC is only ten years old, upgrading to a more efficient model could reduce cooling costs by 20% to 40%.

When choosing a replacement, keep these factors in mind:

  • Seasonal Energy Efficiency Ratio (SEER) Rating: Look for models with a SEER rating of 13 or higher. A higher SEER rating means better efficiency and lower energy costs.

  • Proper Sizing: Make sure the new system is the right size for your home. A unit that's too large won’t effectively remove humidity, while a unit that's too small won’t cool your home adequately on the hottest days.

Regular care of your air conditioning system helps you achieve efficiency, comfort, and savings. Simple maintenance steps keep your home cool during the hottest months, while professional expertise can enhance the performance and lifespan of your AC unit.

If you're unsure about the condition of your air conditioner or need an annual check-up, reaching out to a professional is a smart move. Scheduling a yearly AC tune-up with Sears Home Services keeps your system running smoothly, providing reliable cooling and reducing energy bills.
