There are lots of factors to clean up the duct in your house. When ducts are clean, the heating system lasts longer (because there is less dirt wearing its parts), we dust less frequently, and the air we breathe at home is cleaner. For those of us with allergies, this need to be a welcome enhancement.
Most likely you don't own a high-powered, truck-mounted vacuum system with 150 foot-hoses; perhaps you can't manage the expense of such service. However I am going to tell you how you can clean duct yourself. Sure, you will not be able to reach every nook and cranny, but you can still eliminate approximately 85% of the dust in your system without investing any more than the cost of your brand-new heater filter.
There are several designs of duct systems, such as attic systems and underground systems, but the theory of cleaning up these systems is the exact same. You may not be able to gain access to all parts of these systems (for instance, underground ducts), but you can make a difference in your air quality by cleaning up the parts of the system that you can reach.
Prior to we start, take a look at this video of what one of those high-powered, truck-mounted vacuum systems appears like at work on a quite overlooked duct system.
2. Turn on fan. You desire the fan running while you are cleaning up, to move the dust along that you are going to loosen with your banging and brushing. Set the thermostat to "fan on," and shut off the "heat/cool" mode so that just the fan is running. If you do not have a fan-only option, you can run the heat, or you may take this chance to install a newer thermostat with this handy alternative.
3. Inspect filter. Make sure your old heater filter remains in place, so that the dust you knock loose doesn't wind up getting pulled into the fan motor.
4. Loosen dust in ducts. Knock loose any buildup of dust in the duct. Just take the deal with of your brush and begin tapping on any available duct work you have in the basement. This will help separate any deposits of dampened dust that might have stuck to the within the duct.
5. Tidy supply registers. Now you can start purging the dust in your supply registers. With the vacuum running and the end of the tube near the register, raise the register. Use the tube to capture any dust that is being pushed out by the fan, and continue to sweep as far into the register's piping as your pipe can reach. Use your brush to scuff loose any built up dust in the register.
As you go through your home sweeping out the supply registers, you can get rid of and deal with the paper towels you've put in location. 6. Clean return air registers. Purge your return air registers. These will likely be fastened with a screw and need your tool to remove them. Again, brush and sweep as far back into the register piping or cavity as you can. 7. Shut down fan and heating system. Shut the fan off at the thermostat and the power off to the furnace by means of the service switch or breaker panel. Do not just shut off the thermostat, since that doesn't turn off the power to the system.
8. Clean out blower compartment and return air boot. With the power off, you can get rid of the panels on the front of the heating system and access the blower compartment and the return air boot. Utilize your vacuum to sweep up the dust developed in the blower compartment and return air boot. This is where the great bulk of your dust will be. Given that you're in here, you should clean up the heating system fan too.
Have an appearance at the detailed get more info post (with photos) I wrote, How to Clean a Heater Fan for a guide on doing this. 9. Replace heater filter. Purchasing a better filter will absolutely reduce the dust in your house. However the better the filter, the more typically you ought to alter it; a filthy filter restricts the air flow to the fan, which results in the blower motor running hotter and lowering its life expectancy. How often you need to change your filter depends upon your home, your pets, and your place.
