Top 6 Ducted AC Maintenance Tips to Try Now

If you have a ducted air conditioner, keeping it in good condition is important. Regular maintenance can help you avoid expensive repairs and maximize your energy efficiency, so you stay comfortable throughout the summer. Here are our top 6 ducted AC maintenance tips to try and when to call N.E.T.R., Inc. for professional upkeep.

1. Clean Your Filters 

Dirty air filters are one of the most common causes of poor system performance. This is because air can’t pass through a filter that has been clogged with dust, hair, and other debris. This causes your system to work harder and raises your electric bills.

Pro Tip

Check your filters every 1 to 3 months and clean them with warm, soapy water as needed. People with allergies or pets may need to clean their filters more often.

2. Clean Your Evaporator and Condenser Coils

Over time, the evaporator and condenser coils in your system collect debris, which reduces their ability to absorb and release heat. This leaves your space hot and humid, even when your air conditioner is running at full blast. 

Pro Tip

Cleaning your coils is easy. Start by turning off the power to your system and removing the access panel on the indoor unit. Then, gently clean the evaporator coils using a soft brush or no-rinse coil cleaner.

For your outdoor condenser coils, remove debris that may have collected around your unit. Then, gently spray the coils with a garden hose from the inside out with low pressure. You can also use a coil cleaning solution specifically designed for outdoor use.

3. Clean the Condensate and Drain Lines

Air handlers have condensate drains inside them that collect moisture from your indoor air and drain it away from the unit. This water is typically funneled through a small pipe that drains outside or into your plumbing. But over time, this line can get clogged with algae, mold, and debris.

Pro Tip

It’s a good idea to flush your drain line before the cooling season begins just as a standard practice. You can do this by mixing equal parts water and vinegar (or water and bleach) and using a funnel to pour the liquid into the line. Letting the mixture sit for a half hour before rinsing will help break down and remove more deposits.

4. Check Your Refrigerant Levels

Refrigerant is the liquid that your ducted AC system uses to remove heat from your space and transfer it outside, where it can be released into the air. Low refrigerant levels often indicate a leak and may cause your system to cool inefficiently or stop working altogether.

Pro Tip

Low or leaking refrigerant isn’t a DIY fix, so you’ll need to contact a licensed HVAC technician to check your system and recharge your refrigerant.

5. Check Your Thermostat

Your thermostat is the command center of your system and is what tells your AC when to speed up or slow down to adjust the temperature in your space. If there’s a problem, it can cause your system to short cycle or have difficulty maintaining consistent temps.

Pro Tip

Check the accuracy of your thermostat by comparing its readings with those of a separate room thermometer. If your thermostat is inaccurate, you can recalibrate or replace it. Consider upgrading to a smart thermostat for better energy efficiency and remote control options.

6. Schedule Professional Maintenance Every Year 

Even the best DIY maintenance can’t replace the benefits of a professional inspection. You need a qualified HVAC technician to check your system’s electrical components, test its performance, clean internal parts, and identify any issues before they turn into major repairs. This should be done annually for optimal efficiency.
