Mini-splits require monthly cleaning to function correctly. While ductless mini-splits are relatively easy to maintain, it is still recommended to have a professional inspect them every so often.
Constant circulation of pollen, animal dander, dust, and dust mites through it and its air filters necessitates regular maintenance. Mold can grow and accumulate if you don’t clean the HVAC system’s components, which can aggravate respiratory problems.
Every ductless mini-split indoor unit has one or more air filters on the front panel that must be checked and cleaned every two weeks. Cleaning ductless filters are vital for clean, fresh airflow. When you see dust on your filter, clean it. Here are the steps to cleaning filters.
Ductless filters don’t last forever. Many ductless mini-split owners need to consider system upkeep and filter expiration dates. Depending on your system’s maintenance schedule, ductless filters last three months to three years. Consult your manufacturer’s guidelines or contact us for ductless filter lifespan information.
Before replacing filters, date them. It will help you remember when you put them in the unit and when they need cleaning or replacement. Some write the date they need to replace the filters, not when they did. It’s your part!
A photo of your unit’s make and model may help. The image will be ready if you need to reference it for an HVAC specialist or our staff quickly.
Your make and model are on the indoor unit’s manufacturer’s label. We recommend using your unit’s information rather than the manual. Your manual may cover multiple sizes, leading you to buy the wrong filters.
Unplug and shut down the system monthly. Spray the housing grate fins with a garden hose or a damp rag. Remove the cover to expose the pump and coils, then vacuum or blow off the dust. Wash the fan coils with a hose and turn it on. If the fan wobbles, get it fixed.
If you plug in a wet unit, you risk electrocution and damage.
Air conditioner maintenance is easy to overlook. Having bulk air filters available reduces the risk of missing the expiration date. Buying filters in size is cheaper than individually. Buy suitable filters. HEPA Filter Sales sells annual packs for your model, so you’re prepared all year. We’re also here to answer your filter questions.
