Summer is just around the corner, and that means cranking up the air conditioning to beat the sweltering heat. While professional AC service from experts like All Weather Heating and Cooling Inc. is always recommended, there are a few simple DIY tasks you can undertake to keep your HVAC system running smoothly.

1. Change the Air Filter

A clogged air filter can significantly reduce the efficiency of your AC unit and even lead to costly breakdowns. Experts recommend changing the filter every 1-3 months, depending on the type of filter and the level of usage. Here’s how to do it:

  1. Locate the air filter compartment, usually in the return air duct or the blower compartment.
  2. Remove the old filter and inspect it for excessive dirt or damage.
  3. Install the new filter, ensuring it’s properly aligned and fits snugly.

2. Clear Debris Around the Outdoor Unit

Your outdoor AC unit needs proper airflow to function correctly. Regularly clear away any leaves, twigs, or debris that may have accumulated around the unit. Additionally, trim back any vegetation that’s encroaching on the unit, as this can block airflow and reduce efficiency.

3. Clean the Condenser Coils

The condenser coils are responsible for dissipating heat from the refrigerant. Over time, they can become clogged with dirt and debris, reducing the unit’s ability to cool effectively. To clean the coils:

  1. Turn off the power to the unit.
  2. Use a soft-bristle brush or a coil cleaning tool to gently remove any buildup on the coils.
  3. Rinse the coils with a garden hose, being careful not to bend or damage them.

4. Inspect and Clean the Condensate Drain

The condensate drain is responsible for removing moisture from the AC unit. A clogged drain can cause water to back up and potentially damage your system. To clean the drain:

  1. Locate the drain line, typically a PVC pipe near the indoor unit.
  2. Pour a solution of vinegar and water down the drain to help dissolve any buildup.
  3. Use a small wire or drain snake to dislodge any stubborn clogs.

Remember, while these DIY maintenance tips can help extend the life of your HVAC system, it’s still crucial to schedule regular professional maintenance and tune-ups.
