How To Clean Your HVAC System?

Do you know how to clean your HVAC system? While we recommend trusting an HVAC professional for deep cleaning, homeowners can take regular steps to ensure that these systems run for a long time. Landlords and commercial building superintendents can do the same, providing comfort for the tenants.

You want to avoid clogs in an airflow system. These clogs can disrupt the regular flow of heated and cooled air to parts of a home or business. Dust can cause these blockages while bringing in allergens like pollen or recirculating pet dander. They also may increase the likelihood of illness.

Steps For Cleaning Your Heating and Cooling Systems

Have several tools on hand if taking on this task:

  • A vacuum cleaner with different hose attachments
  • Microfiber cloths or paper towels
  • Antibacterial wipes
  • Different brush types

Create a maintenance schedule ideally, especially if you own a commercial building. Then you can keep the system clean.

Turn Off Your Power

Safety is a priority. Before cleaning whatsoever, make sure that the air conditioner and furnace are off. If anything, you may want to run the fan to break up accumulated dust while covering the supply registers.

If you want to be extremely careful, label the fuse and switch it off; however, that shouldn’t be necessary. Flip the off switch on your HVAC control, which should be sufficient.

Vacuum Or Sweep The Supply Registers

Prepare a vacuum with the appropriate hose attachment. It should fit into the vents and ideally have a brush accessory. A stiff-bristled brush should help you reach the areas that the vacuum cannot when you need to engage in sweeping.

Open And Clean The Return Air Registers

If you have the right screwdriver and have the confidence for this as a homeowner, open the return air registers. Remove them and wipe them down if you see clogs.

Check your vacuum hose attachment to see that it can fit into the areas and reach the more challenging spaces where dust may collect. A long-handled brush will assist as well.

Open And Wipe Down Air Ducts

Remove the grates and grills that lead to the air duct. Wipe them down and remove any dust. Then use a long-handled hose attachment to vacuum the inside passageways. Keep your eyes out for dust.

WIpe down the air ducts where you can reach, using antibacterial substances. Since air conditioners use condensation to cool air, water can drip and encourage mold to grow.

Replace Air Conditioning And Furnace Filters

The filters in your HVAC exist to catch contaminants, including dust and mold. After a few months, the filters become clogged with debris. Then that impedes airflow and forces the motor to overwork.

Measure your vent size before ordering any filters. Specific dimensions allow for a better fit and avoid contaminants from flying through the gaps.
