What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Check Your Air Filters

Start by inspecting your air filters. A dirty filter can restrict airflow and affect your HVAC system's efficiency. Replace or clean filters if they appear dirty.

2

Inspect Ductwork for Blockages

Look for any visible blockages in your ductwork, such as dust buildup or furniture obstructions. Clear these blockages to improve airflow.

3

Examine Thermostat Settings

Ensure your thermostat is set to the desired temperature and is functioning correctly. If you have a programmable thermostat, check if it's set to the right schedule.

4

Listen for Unusual Noises

Pay attention to any strange sounds coming from your HVAC unit. These can indicate mechanical issues that may need professional attention.

5

Check for Odors
