Generally, replace your AC filter every 90 days (or 3 months). The filter collects dust, dirt, pet hair, and other allergens, keeping them from circulating in your home. Over time, it clogs with debris, making it harder for your AC to work efficiently.

However, a few factors can impact this timeline:

• Allergies: If anyone in your household has allergies, consider changing the filter every 60 days for cleaner air.
• Environment: If you live in a dry, dusty area or where pollen levels are high, more frequent replacements—every 60 days—can improve air quality.

Q: How can I tell if my air conditioner might be about to fail?
A: Watch for signs like unusual sounds, reduced cooling, and strange odors. These symptoms often indicate underlying issues that need attention, especially during peak season.

Q: What kinds of sounds should concern me?
A: While AC units can be noisy, certain sounds signal problems. A hissing noise, for example, may point to issues with the ductwork, which can stress the unit and lead to breakdowns if not addressed.

Q: What does it mean if my AC isn’t blowing cold air?
A: If the air isn't as cold as it used to be, your system might be struggling to keep up. Possible causes include duct leakage, condenser issues, or low refrigerant levels.

Q: Are strange smells from my AC a sign of trouble?
A: Yes, unusual odors, like a musty smell, may signal mold in the ductwork or unit. Odors often indicate poor maintenance, which can lead to bacteria growth on the AC coil.
