How to Visually Inspect Your HVAC Unit
It is a good habit to do a visual inspection of your HVAC system every one or two months. You should look at the thermostat, indoor and outdoor units, registers and returns. A few hints on what to look for:
- Check the battery in your thermostat
- Is the condensate system draining properly?
- Is your flue securely attached?
- Registers and returns should be free from blockages
- Look for evidence of mold
- Is your outside unit level?
