1. Check your thermostat

• Make sure it’s set to the correct mode (HEAT or COOL).
• Replace the batteries if it’s been a while or if the screen is dim.

2. Replace or clean your air filter

• Check your filter for dust buildup.
• Replace it every 1–3 months (or clean it if it’s washable).
• A clogged filter can cause poor airflow and higher energy bills.

3. Inspect your vents and registers

• Make sure they’re open and not blocked by furniture, rugs, or curtains.
• Wipe away any visible dust or debris.

4. Listen and smell

• Turn on your system and listen for unusual noises (rattling, banging, squealing).
• Be aware of any odd smells like burning or mildew.

5. Check your outdoor unit (if you have one)

• Make sure there’s no debris, leaves, or vegetation blocking airflow.
• Clear at least 2 feet of space around it.
• Visually check that the fan spins freely when the system is running.

6. Check for proper airflow

• Walk through your home to make sure air is coming from all vents.
• Weak or no airflow could mean a duct or blower issue.

7. Inspect your condensate drain (for cooling season or heat pumps)

• Look for water pooling near the indoor unit or drain line — that can signal a clog.

8. Review your maintenance records
