5 Signs It's Time to Change Your AC Filter in Lewiston, ID

All we need during the hot summer days is a room filled with cool and fresh air. A working air conditioner can feel like a lifesaver when the temperatures rise. However, if your AC is no longer cooling as effectively as it once did, it may be time to check and replace the air filter.

At Unlimited Heating & Refrigeration Inc., we provide reliable AC repair services in Lewiston, ID, and we’ve listed five key signs that your AC filter needs replacement.

1. Reduced Cooling Efficiency

If your air conditioner isn’t cooling the room like it used to, a clogged or damaged filter might be to blame.

  • A dirty filter restricts airflow, preventing cool air from circulating properly.
  • If you’re experiencing this issue, contact an HVAC professional to inspect or replace the filter.

2. Overheating HVAC System

Is your AC unit heating up quickly?

  • Restricted airflow from a clogged filter causes the system to overwork and overheat.
  • This adds pressure to the entire unit and could lead to mechanical damage.
  • A technician might suggest cleaning or changing the filter to avoid further stress on the system.

3. Dust and Debris Near Vents

Noticing dust build-up around your ducts or vents?

  • This is often caused by a worn-out or clogged filter.
  • As dust accumulates on the filter, it starts escaping into your room through the ducts.
  • Regular cleaning and filter replacement can help maintain cleaner indoor air.

4. Worsening Allergies

Are your indoor allergies acting up?

  • A dirty filter collects dust, pollen, and other allergens.
  • When the AC is running, these particles can be circulated back into your home, worsening allergy symptoms.
  • If you notice increased sneezing or respiratory discomfort indoors, it's time to check your filter.

5. High Electricity Bills

A sudden spike in your electricity bill?

  • A clogged filter forces the system to work harder, drawing more energy.
  • If your power usage has increased without a clear reason, the filter could be the culprit.
  • Routine filter maintenance can help keep energy bills under control.
