Over the past several years, ductless mini splits have become an increasingly popular cooling and heating option for homeowners across the United States. They’re versatile and require no ductwork. But like any other cooling or heating system, mini splits require regular maintenance. Fortunately, this is fairly easy to do, with the assistance of your expert HVAC-system technician. One of the most crucial aspects of maintaining a ductless mini split is making sure the air filter is checked regularly and changed as soon as it looks dirty.
VACUUM YOUR DUCTLESS FILTERS REGULARLY
Every indoor unit of a ductless mini-split air conditioner has one or more air filters located on the front panel, which require checking and potentially cleaning once every two weeks. Proper cleaning ofductless filters is vital for a clean, fresh, and healthy airflow. If you see dust on your filter, it might betime for a cleaning. Follow the steps below to clean it properly. Another method for filter cleaning is to wash them with lukewarm water and a very mild detergent. Always consult your user manual for this step.
DATE YOUR FILTERS BEFORE PLACING THEM IN YOUR UNIT
Did you know that your ductless filters don’t last forever? It may seem like something that makes sense but we find many ductless mini-split owners don’t even consider the overall upkeep of their systems, let alone the expiration dates on their ductless filters. Depending on the recommended maintenance schedule for your system, ductless filters last for 3 months to 3 years, depending on the filter and your use. Also consult your manufacturer’s guidelines orcontact us to learn the lifespan of your ductless filters.
TAKE A PHOTO OF YOUR UNIT’S MAKE AND MODEL
Having a photo of your unit’s make and model handy could be advantageous. If you need to quickly reference it for anHVAC specialist or our staff when you call regarding filters, the photo will be ready to go to get your questions and concerns answered quickly.
Your make and model information can only be found on the manufacturer’s label, which is located on the indoor unit. We recommend relying on the information located on your unit, not your user manual. Your manual might apply to several different sizes and can mislead you into buying the wrong filters.
SAVE YOUR MINI-SPLIT USER MANUAL
Understanding a machine’s every function is ideal for maximum efficiency. It’s unlikely you will remember every one of your mini-split’s settings and parts, so keeping its user manual in a safe and convenient place for reference will be helpful for effortless usage. If you rely on your ductless mini-split unit, it’s a great idea to have it professionally maintained per your manual to protect your warranty and cleaned at least every 2 to 3 years with a deep cleaning. Both your indoor and outdoor units will need a deep cleaning.
BUY BULK FILTERS TO REMEMBER WHEN YOU NEED TO REPLACE THEM
It’s easy for most of us to forget about maintaining our air conditioners. Having bulk air filters readily available for when it’s time to change them greatly diminishes the chances of missing the expiration date. Plus, buying filters in bulk costs less per product them buying filters individually. Just be sure youbuy the correct filters!
