Air Vent Cleaning

It’s not widely known the findings recorded and that the legal requirement with respect to ventilation system hygiene is that the systems are inspected. This is a requirement applies to owners and operators of workplace premises and laid down in the Health and Safety at Work Act.

There has been a general acceptance that unclean ventilation systems can spread airborne infections in the office including flu and the common cold, leading to increases in the sickness days taken in workplaces.

At CPR Carpet Cleaning we use the most advanced techniques of tracking and cleaning of ventilation systems. The latest readings diagnose and to collaborate the most cost effective and least disruptive way of cleaning your venting systems are used by our surveyors.

Reduce Dust in Your Home and Save Money

There are many reasons to clean out the air ducts in your property. When ducts are clean, the heating system lasts longer (since there is less dirt wearing out its parts ), we dust less often, and the air we breathe at home is cleaner. For those people with allergies, this should be a welcome improvement.

Probably you don’t own a high-powered, truck-mounted vacuum system with 150 foot-hoses; perhaps you can’t afford the price of such service. But I am going to tell you how you are able to clean air ducts yourself. Sure, you won’t be able to reach every nook and cranny, but you can still eliminate roughly 85% of the dust on your system without having to spend any more than the price of your new furnace filter.

There are lots of unique designs of duct systems, such as attic systems and underground systems, but the concept of cleaning these systems is exactly the same. You may not be able to access all parts of these systems (for example, underground ducts), but you can make a difference on your air quality by cleaning the areas of the system that you can reach.

Before we get started, check out this video of what among these high-powered, truck-mounted vacuum systems seems like at work on a pretty neglected duct system.

Things You Want To Clean Your Air Ducts

1. Furnace Filter. 

You will surely require a new furnace filter at the end of the job. Ensure you opt for the right filter option for you.

2. Vacuum. 

A household-type vacuum with a decent hose attached will work, but a heavier-duty”Shop Vac” unit is better, if available.

3. Brush. 

Something closely resembling a toilet brush will do the job best, but a stiff-bristle paintbrush or something similar will do.

4. Screwdriver or Hex Driver. 

Your registers are likely held in place by some type of fasteners. You will need to use whatever tool fits the attachments, usually a Phillips screwdriver or 1/4″ hex driver.

5. Paper Towels. 

Unless you would like to do a great deal of dusting and sweeping right after you clean your ducts, you’ll find these useful to cover some registers while you clean others.

Step-By-Step Duct Cleaning

Step-By-Step Duct Cleaning

1. Cover supply registers. Start by covering up your supply air registers (openings that provide heated air to the chambers ) with paper towels. You do this to keep dislodged dust from drifting into the rooms as you work. Just lift the register, wrap the paper towel on the top of it, and replace it.
2. Turn on fan. You want the fan running while you’re cleaning, to move the dust along that you’re likely to loosen with your banging and brushing. Set the thermostat to”fan on,” and shut off the”heat/cool” mode so that only the fan is running. If you don’t have a fan-only option, you can run the heat, or you might take this opportunity to put in a newer thermostat with this very helpful option.
3. Check filter. Make certain your old furnace filter is set up, so the dust you knock loose doesn’t wind up getting pulled into the fan motor.
4. Loosen dust . Knock loose any buildup of dust in the duct work. Simply take the handle of your brush and start tapping any accessible duct work you’ve got in the basement. This can help break up any deposits of dampened dust that may have stuck to the insides of the duct.
5. Clean supply registers. Now you can begin sweeping out the dust on your supply registers. With the vacuum running and the end of the hose near the register, lift the register. Use the hose to grab any dust that has been pushed out by the fan, and proceed to sweep as far into the enroll piping as your hose can reach. Use your brush to scuff loose any built up dust in the register. As you proceed through the home sweeping out the supply registers, you can remove and dispose of the paper towels you have put in place.
6. Clean return air registers. Sweep out your return air registers. These will likely be fastened with a screw and require your tool to remove them. Again, brush and sweep as far back into the register piping or cavity as possible.
7. Close off fan and furnace. Close off the fan at the thermostat and off the power to the furnace via the service switch or breaker panel. Do not just shut off the thermostat, because that doesn’t switch off the power to the unit.
8. Clean out blower compartment and return air boot. With the power off, you can remove the panels on the front of the furnace and get the blower compartment and the return air boot. Use your vacuum to sweep up the dust built up in the blower compartment and return air boot. This is where the great bulk of your dust will be. As you’re in here, you should clean out the furnace fan also. Take a look at the detailed article (with pictures) I wrote, How to Clean a Furnace Fan for a guide on doing so.
9. Replace furnace filter. Purchasing a better filter will surely cut down on the dust in your home. But the better the filter, the more frequently you should change ita dirty filter limits the airflow to the fan, which causes the blower motor running hotter and reducing its lifespan. How often you need to change your filter is dependent on your home, your pets, and your location.

There are several video’s on youtube of companies that clean air heating vents, but there are none that show how you can clean them yourself. This is a video i made when i decided to try and clean my air ducts by myself. I used a shop vac and a leaf blower to do the entire job.
