Maintaining your air conditioning system can save you money and extend its lifespan. While professional service is recommended for major repairs or installations, there are several DIY tasks you can undertake to keep your system running smoothly. This article from Bruton Comfort Control provides practical tips to help you tackle some basic AC maintenance tasks.

Clean or Replace Air Filters

  1. Locate the air filter(s) in your system. They are typically found in the return air ducts or the blower compartment.
  2. Inspect the filter(s) and clean or replace them as needed. Disposable filters should be replaced every 1-3 months, while reusable filters can be cleaned with a vacuum or water.
  3. Make sure the new filter is properly installed, ensuring a tight fit to prevent air leaks.

Clear Debris from Outdoor Unit

  1. Turn off the power to the outdoor unit before working on it.
  2. Use a soft brush or vacuum to remove any leaves, dirt, or debris that has accumulated on the unit’s fins and coils.
  3. Trim back any vegetation or shrubbery that may be obstructing airflow around the unit.

Check and Clean Condenser Coils

  1. Locate the condenser coils, which are typically found in the outdoor unit.
  2. Use a soft brush or coil cleaning tool to gently remove any dirt or debris from the coils.
  3. Be careful not to bend or damage the delicate coil fins during cleaning.

Inspect and Insulate Ductwork

  1. Visually inspect your ductwork for any signs of leaks, holes, or damage.
  2. Seal any gaps or cracks with duct sealant or metal-backed tape.
  3. Ensure that exposed ductwork is properly insulated to prevent energy loss.


By following these DIY tips, you can help maintain the efficiency and longevity of your air conditioning system. Remember, if you encounter any complex issues or feel uncomfortable performing certain tasks, it’s always best to seek professional assistance from a certified HVAC technician like those at Bruton Comfort Control.
