Get Your AC Summer-Ready with These 5 Essential Maintenance Tips

Summer heatwaves can push your air conditioning system to its limits. When temperatures soar, a well-maintained cooling system keeps your home comfortable and energy bills manageable. If you live in Kalamazoo or similar climates, preparing your AC before the heatwave hits is crucial. Skipping maintenance can lead to breakdowns, costly repairs, or inefficient cooling when you need it most.

This guide covers five critical checks to get your AC ready for summer. These tips help you avoid surprises and ensure your system runs smoothly all season.

1. Clean or Replace Air Filters

Air filters trap dust, pollen, and other particles before they enter your home. Over time, filters clog and reduce airflow, forcing your AC to work harder. This increases energy use and wears down components.

• Check your filter monthly during heavy use.

• Replace disposable filters every 1-3 months.

• Clean reusable filters according to manufacturer instructions.

  
  

Clean filters improve air quality and cooling efficiency. HVAC techs often find dirty filters as the top cause of poor AC performance during heatwaves.

2. Inspect and Clear the Outdoor Unit

The outdoor condenser unit needs clear airflow to release heat effectively. Dirt, leaves, and grass clippings can block vents and reduce cooling capacity.

• Turn off power to the unit before cleaning.

• Remove debris around the unit.

• Gently hose down the fins to clear dirt.

• Straighten bent fins with a fin comb if needed.

  
  

A clean outdoor unit helps your AC maintain steady cooling even in the hottest weather. Kalamazoo homeowners often overlook this simple step, leading to overheating and system shutdowns.

3. Check Refrigerant Levels

Refrigerant absorbs heat from inside your home and releases it outside. Low refrigerant levels cause your AC to struggle and cool less efficiently.

• Signs of low refrigerant include weak airflow, longer cooling cycles, and ice buildup on coils.

• Only certified HVAC techs should check and recharge refrigerant due to environmental and safety regulations.

  
  

Scheduling a professional check before the heatwave ensures your system has the right refrigerant charge for peak performance.

4. Test Thermostat Settings and Function

Your thermostat controls when and how your AC runs. Incorrect settings or a malfunctioning thermostat can waste energy or leave your home too warm.

• Set the thermostat to a comfortable temperature, typically around 78°F when home.

• Use programmable or smart thermostats to adjust cooling based on your schedule.

• Test the thermostat by setting it lower than room temperature and confirming the AC turns on.

• Replace batteries if needed.

  
  

Proper thermostat function helps your cooling system run efficiently and keeps your home comfortable during heatwaves.

5. Schedule a Professional HVAC Inspection

Even with regular DIY maintenance, a professional inspection is essential. HVAC techs can spot hidden issues, clean internal components, and perform safety checks.

• Ask for a full system tune-up before summer.

• Technicians will inspect electrical connections, motors, and ductwork.

• They can identify worn parts and recommend repairs before a breakdown.
