Boost Comfort with DIY AC Maintenance


Maintaining your air conditioning unit is crucial for ensuring optimal performance, efficiency, and longevity. While professional HVAC repair services are recommended for complex issues, there are several DIY steps you can take to keep your AC running smoothly. In this article, we’ll explore some easy-to-follow tips to help you maintain your AC unit like a pro.

Clean or Replace Air Filters

  1. Locate your AC unit’s air filter, typically found in the return air duct or behind the front panel.
  2. Check the manufacturer’s recommendations for when to clean or replace the filter.
  3. If reusable, clean the filter by vacuuming or washing it with mild soap and water.
  4. If disposable, replace the filter with a new one of the same size and type.

Clogged filters restrict airflow and reduce efficiency, so regular filter maintenance is essential.

Clear Debris from the Outdoor Unit

  1. Turn off the power to the outdoor unit for safety.
  2. Use a soft-bristle brush or vacuum attachment to remove any leaves, twigs, or dirt accumulated around the unit.
  3. Trim back any vegetation growing too close to the unit, allowing at least two feet of clearance.

Proper airflow is critical for efficient operation, so keep the outdoor unit clear of obstructions.

Check for Leaks

  1. Inspect the refrigerant lines for any signs of wear, cracks, or leaks.
  2. If you notice any leaks, contact a professional AC repair service immediately, as refrigerant leaks can be hazardous and require specialized equipment to handle.

Refrigerant leaks can significantly impact your AC’s performance and efficiency, so it’s essential to address any issues promptly.


By following these simple DIY maintenance tips, you can help extend the life of your air conditioning unit, improve its efficiency, and ensure optimal performance. However, for more complex issues or if you’re unsure about any aspect of AC maintenance, it’s always best to consult with a professional HVAC service provider like Ellsworth Home Services in Gilbert.
