Cleaning out your furnace is an operation that can be performed by a Denver HVAC specialist as a part of the annual maintenance and will help you keep heating bills and repair bills low. If you have some basic skills, you can do the cleaning yourself, but if you are not sure about this, you should call a HVAC technician who can safely do it for you.
Before starting to clean out your furnace, you must turn off the gas and electricity to your furnace and open all access panels.
First, you need a vacuum cleaner and some of its attachments. With the vacuum brush on, clean dust and debris around the motor, inside the burner compartment, from other mechanical parts and from fan blades. For hard to reach areas, change the brush with the crevice tool. Be extra careful not to disconnect wires in the vacuuming process. Use a soft cloth, slightly damp, and wipe down your furnace. If you notice any loose terminals, use a screwdriver and tighten them.
Check the motor belt; if it is loose or if you see cracks, take it to the hardware store, find a match and replace it. Clean the ducts too, with a high-powered vacuum cleaner with filter that prevents dust from scattering throughout the house.
When you change the filters of your furnace, make sure to buy quality products, for a better efficiency.
