How to Clean a Ductless Air Conditioner Unit In Order to Improve Air Quality

It’s rewarding to sit back once your ductless heating and cooling system is installed and reap the benefits of that nice cool air. You’ll definitely want to keep that cool air coming and your unit operating at its optimum level. To ensure the quality of your air is top-notch, it’s important to keep your ductless air conditioner clean. Here we offer tips on how to clean your ductless air conditioner to make the most of your efficient ductless heat pump in Olympia, WA.

Why Clean Air from Ductless Units Matters 

Ductless air conditioners are known to be great for filtering the air. With the variable speed inverter technology in ductless heat pumps, the air is always moving through your home. As a result, your heat pump continuously traps the particles and thus filters the air better than other traditional cooling systems. 

A ductless air conditioner, paired with a purifier, provides great health benefits as it removes smoke particles (we see this a lot from northern California and Washington forest fires), smog, dust, dirt, and microorganisms/fungi from the air you breathe. Thankfully, it’s easy to breathe well with a properly maintained and cleaned ductless air conditioner. 

Dust and Vacuum Your Interior Units

While you’re dusting and vacuuming the rest of the house, include a quick dust of your indoor unit’s filter. By running your vacuum over the unit, you will remove the dust and allergens that can interfere with the air’s quality. You can also locate the filter and gently wipe it to clear away dust and dirt. This is an important step because the system will struggle to pull in air, with dirty filters and your room will feel hotter or colder than it should. You’ll want to do this more often if you have pets!

Keep Indoor Units Free of Clutter

One of the reasons you chose your ductless air conditioner in the first place probably has something to do with how little space they take up. However, for them to run smoothly you need to make sure the area around the indoor units is clear. Not only do things like furniture and even art on the walls block the vents from dispersing the cool air evenly, but they can actually add to dusty buildup that interferes with air quality and efficiency. Give the units about four feet of space to help them do their job properly.

Clean Your Exterior Unit

Try to wipe down your exterior unit with a damp cloth and gentle cleaner when you’re out watering the lawn or tending to your garden. This can help reduce the risk for clogs that can lead to costly repair calls. Exterior units should be clear of vegetation overgrowth in the summer and ice and snow in the winter. Clearance should be about two feet on either side and four feet in front of the unit, too. Ensure you don’t stack anything on top of your unit. 

Clean the Outdoor Compressor

Last but not least, northwest Washington weather can really hit your system with a lot of dirty buildup. To tackle cleaning the outdoor compressor, you can use a leaf blower to blow away debris. Next, use your garden hose to very carefully remove dirt. Do not attempt to use any high-pressure air or water. Gently wipe everything dry.

Get Your Ductless Unit Cleaned Professionally 

Sometimes, the best way to get the job done without causing damage or creating a mess is with a professional cleaning. Having your unit deep-cleaned and inspected will save you time and ensure peace-of-mind knowing that your unit is operating at its optimum efficiency.
