Yes, you can clean your furnace yourself, but it is important to proceed with caution as furnaces can be dangerous if not handled properly.
Turn off the Power: Before you begin cleaning your furnace, make sure to turn off the power to the unit. You can do this by switching off the power switch on the furnace or by turning off the circuit breaker that powers the furnace.
Remove Dust and Debris: Using a soft-bristled brush or a vacuum cleaner with a brush attachment, gently clean the exterior of the furnace, removing any dust and debris that may have accumulated on the surface.
Clean the Blower: Remove the furnace blower door and use a brush to clean the blower assembly, including the blades and the housing. You can also use a vacuum cleaner with a brush attachment to remove any dust and debris that may have accumulated inside the blower.
Replace the Air Filter: Check the air filter and replace it if it is dirty or clogged. This is a simple but important step in maintaining the efficiency of your furnace.
