A Summer AC Maintenance Checklist for Homeowners

Consumers spend over $10 billion each year on HVAC repair or maintenance. Coil and maintenance cleaning costs $150 to $300. Before paying for extensive repairs, use this AC maintenance checklist.

Caring for your air conditioner can help you avoid more expensive repairs later. You can keep your home comfortable and cool as we roll into summer. Read on to maintain a functioning air conditioner today!

Change the Filters

Every day, your AC unit's air filter collects dust, dander, and other particles. This keeps airborne pollutants from spreading throughout your home. Replacing your air filter ensures optimal airflow and efficiency.

In fact, replacing a clogged filter could lower your air conditioning unit's energy consumption by as much as 15%. Otherwise, air will have a more difficult time moving through the filter.

Your unit will push twice as hard to emit air, causing your energy usage to rise. Components could experience wear and tear.

These components may need replacement. The entire unit could even break down. 

When the filter clogs up, airflow can become obstructed. Air will bypass the filter, depositing dirt into the evaporator coil. This will impair the coil's heat-absorbing abilities. 

Before that happens, set a reminder on your phone to replace the filter every three months. Replace it more often if:

• You have pets
• The unit is in constant use
• Your home is dusty

Talk to an HVAC technician about filters with different MERV ratings. A filter with a higher rating is more effective at collecting small particles. Using a better filter could improve your home's indoor air quality. 

For residential properties, a MERV rating between seven and 13 is ideal.

Inspect the Lines

Has your AC unit started producing hot air? Check the unit's refrigerant lines, located in the exterior air handling unit and condenser. Make sure the lines are clogged or leaking. 

If you notice ice on the lines, don't touch the tubes. Instead, turn the unit off. Head inside and turn the thermostat's fan setting on.

An HVAC technician can show you how to clean your drain line using vinegar. You should:

• Locate the condensate drain line
• Identify the access point
• Remove the cap at the top of the drain
• Check for blockage
• Add 1/4 cup of distilled vinegar to the line
• Let the vinegar sit for 30 minutes
• Flush the pipe out with water

You can repeat this process each month to remove bacteria or buildup. This will keep everything operating properly.

Check the Thermostat

If you're experiencing issues with your AC unit, check the thermostat before calling a technician. Most families in the US spend $2,000 on energy every year. Half of that goes to keeping homes warm or cool.

You'll spend even more if your unit isn't responding to your thermostat's settings. First, confirm that the thermostat is programmed to the right temperature.

If it's not responding, check the power supply. Make sure it's not disconnected from electricity or using dead batteries.

Consider switching to a smart thermostat this year. You can adjust your home's temperature from your phone. This technology can improve the unit's energy efficiency, saving you money and stress.

Clean the Coils

Don't skip cleaning your air conditioner coils during routine AC maintenance. The evaporator and condenser coils collect dirt over time. A clean air filter should keep them from getting dirty quickly.

As they collect dirt, the coils will reduce airflow. Their ability to absorb heat will decline. Check your evaporator coil every year to avoid this issue.

Head outside to sweep away dirt, debris, and foliage from around the outdoor unit. Determine if dirt has soiled the fins.

Heavy debris could damage the coil fins. If they're bent, they could block airflow through the coil. Request AC care services to keep the fins are in good condition.

Clear the Drain

Pass a stiff wire through your AC unit's drain channels. When channels become clogged, the unit will struggle to reduce humidity. This could cause excess moisture to build throughout your home.

Talk to your HVAC technician for tips on reducing your home's humidity levels. They may recommend using a dehumidifier.

Otherwise, excess humidity can cause mold and mildew growth. You may notice discoloration on your walls or carpets.

Check for Leaks

If cool air still isn't circulating throughout your home, confirm there aren't any leaks. First, check for gaps between your ducts or loose ductwork. Request AC services if anything is loose or damaged.

Schedule routine duct cleaning services. This will keep mildew, mold, or dust from circulating throughout your home. It can also keep pests from affecting your home's indoor air quality.

If you continue experiencing air quality issues, consider using an air purifier. 

Keep the Unit Level

The ground beneath an exterior HVAC unit can shift. Walk around your exterior unit. If it appears uneven, call a professional AC maintenance company.

They'll ensure the unit is level and flat to the ground. Don't try to adjust the unit on your own. 

Request Preventative AC Services

You don't have to worry about caring for your air conditioner alone. Instead, schedule routine AC maintenance. 

Maintenance could extend the lifespan of your unit to over 15 years. This could reduce your need for an expensive replacement sooner than anticipated. 

A technician can:

• Oil motors
• Check belts for wear
• Check the refrigerant levels
• Determine if there are leaks
• Capture refrigerant that must be evacuated
• Measure airflow through the evaporator coil
• Check for and seal duct leakages
• Inspect electric terminals
• Clean and tighten connections

Schedule a maintenance check in the fall or spring. A technician can assess your unit before severe temperatures kick in. You can confirm the unit is working properly to keep your family comfortable.
