How often should I have my furnace cleaned?
The frequency with which you should clean your furnace depends on the environment that your furnace is in.
If you have pets at home or if you have no carpets (carpets prevent dust from dispersing in the air), you wil likely need to clean your furnace and duct once a year. If your furnace is running in an environment with very little dust and hair, you might get away with cleaning it every 2 to 3 years.
