Once considered a curiosity, ductless mini-split A/C systems have grown in popularity among many homeowners throughout the United States. Ductless systems provide roughly the same level of comfort offered by typical central A/C systems, but without the need for expensive and complex ductwork.
Keeping your ductless A/C system in great shape involves following a few simple rules when it comes to care and maintenance:
All Clear on the Outdoor Front
Like your average central A/C system, ductless mini-split A/C systems consist of an indoor air handling unit and an outdoor cabinet housing the condenser and compressor. To transfer heat and keep the compressor cool, the fan mounted near the top of the outdoor cabinet pulls air from the bottom of the cabinet. It's important to keep dirt vegetation and other debris away from this area, since not doing so could cause the components within to overheat.
Make Way for Condensate
Since the typical ductless A/C system is usually wall-mounted, proper condensate disposal is absolutely important. Not only should the condensate drain tube have the proper slope and a kink-free run for efficient drainage, but the proper tubing should also be used. This is especially important in places that experience freezing temperatures during the winter.
Air Filter Changes are Still a Must
No matter what type of A/C system you own, you'll have to keep it free of dust and debris. That means changing the A/C filter that came with the air handler on a regular basis. This will also keep dust from mixing in with the condensate, creating a lumpy and eventually hardened mess that blocks drains and causes interior leaks.
Raising the Dead (Remote)
Instead of a typical thermostat, many ductless AC systems rely on remotes to adjust temperature and fan settings. Occasionally, the remote control may experience a glitch that renders it nonfunctional. The first thing you may want to do is locate and press the reset button on the remote control. Also, make sure the remote and the receiver located on the air handler are in line of sight of each other.
If the above doesn't bring the remote back to its senses, you may have to open the remote and change the battery located inside. The type of battery you'll need depends on the manufacturer, so be sure to read the owner's manual during the replacement.
Keep the above tips in mind as you use your ductless A/C system. With the right amount of care, you'll be able to enjoy it for years to come. (For information on AC repair, contact Armstrong Air, Ref.& Heating - David Armstrong Services, LLC)
