Spring HVAC Maintenance Checklist | Avoid Costly Repairs & Lower Energy Bills!

1. Change or Clean Your Air Filters

Taking care of your air filters is a simple yet essential step to keep your HVAC system running smoothly. It helps maintain good airflow, keeps energy costs in check, and improves the air you breathe indoors. Here’s how to ensure your filters are ready for spring.

Disposable filters usually last around 90 days, but there are exceptions. If you have pets, aim to replace them every 60 days. For allergy sufferers, a change every 20–45 days might be necessary. On the other hand, vacation homes that aren't frequently used can go 9–12 months without a replacement.

Choosing and Maintaining the Right Filter

Here’s a quick guide to help you pick the right filter and keep it in good shape:

Filter Type Replacement Schedule Best For
Fiberglass Every 30 days Basic filtration, budget-friendly homes
Pleated (MERV 8–13) Every 60–90 days Better air quality with balanced airflow
Washable Clean monthly Environmentally conscious households

When selecting a filter, check its MERV (Minimum Efficiency Reporting Value) rating. Filters rated MERV 8 to 13 are ideal for most homes, offering a balance between effective filtration and proper airflow. Keep in mind that filters with higher MERV ratings can restrict airflow, potentially straining your system.

"By having more surface area, you're essentially giving more places for the air to pass through, and the resistance of those filters is lower... Thus, they're going to last longer, and they'll also have less of an impact on the energy use of your system."

  • Peter Straight, CEC appliance efficiency manager

Checking Your Filter's Condition

Here are some simple ways to see if it’s time for a replacement:

  • Hold the filter up to a light source - if you can barely see light coming through, it’s time for a new one.
  • Look for visible dirt or discoloration.
  • Watch for signs like higher energy bills or strange noises from your HVAC system, which could indicate reduced airflow.

Expert Tips for Spring Maintenance

  • Set Monthly Alerts: Use your smart thermostat to remind you when it’s time to replace your filter.
  • Stock Up: Keep a few spare filters on hand so you’re ready when the time comes.
  • Test Airflow: Hang a clean white sheet near a vent. If it turns gray within minutes, it’s a sign the filter needs replacing.

During the mild spring months, consider setting your fan to ON mode to keep air circulating throughout your home. This small adjustment can make a big difference in maintaining fresh, clean air indoors.
