No matter whether you have an HVAC, Heat Pump, or Mini Split system, they all need proper maintenance to function at their best.

Air conditioner and heating vents in your house or apartment can become clogged with dust, dirt, and other debris over time, which can decrease the efficiency of your system and cause it to work harder than necessary.

Cleaning your vents on a regular basis will help to ensure that your system is running efficiently and help to prolong its lifespan.

Here are a few tips on the best ways to clean your air conditioner and heating vents:

Why Should We Clean Them?

First of all, why clean them?

The main reason to keep these areas clean is for better air quality.

Dirty vents can release dust and other allergens into the air, which can cause respiratory problems for you and your family.

In addition, clogged vents can cause your system to work harder than necessary, which can lead to higher energy bills.

How to Clean Air Vents

Step 1

Turn off the power to your HVAC/heat pump system.

Step 2

Unscrew and remove the air duct covers. Using a cleaning Brush, clean away all of the dust and dirt. If the covers are badly soiled, you may need to use soap and water as well.

Step 3

Use your vacuum to clean as much of the air vent as possible. If a regular household vacuum isn’t strong enough to eradicate all of the odors from the vents, you’ll need to rent a heavy-duty vacuum.

Step 4

Use the vacuum to clean the ceiling grills. Dust may fall from these, so be careful while cleaning them since they might cause allergies or asthma.

Step 5

Put the covers back on and turn your HVAC/Heat pump unit back on.

Air vents may be cleaned at any time. Many homeowners like to clean their air vents every four to six months. It’s also a good idea to get your air filter checked if it’s dirty. If your air filter is full of dust, it’s probably time to replace it with a new one, which will prevent dust from immediately filling the ducts and vents again.

Note: We always recommend having your vents professionally cleaned every 3 to 5 years when the ducts are cleaned to avoid costly repairs down the road.

If your covers are really filthy, use a toothbrush or similar brush to remove any remaining dirt or debris.

Wipe down the area around the vents with a damp microfiber cloth to remove any dust that may have fallen out when you removed the covers.

Use a vacuum attachment to clean inside the ducts themselves.

Start at the top of the duct and work your way down, making sure to get all the corners.

If you have a long vacuum attachment, you may be able to reach the entire length of the duct.

Otherwise, you may need to use a smaller attachment or even a brush to clean the sections that are too far away.

Replace the vent covers and screw them back into place.

Ceiling vents can be tricky to clean, but it’s important to do so on a regular basis to ensure good air quality in your home. These tips should help you get the job done quickly and easily.
