Maintaining Your Ductless Heating & Cooling System

May 26, 2019 | Maintenance

Ductless Maintenance

A ductless, or mini-split, heating and cooling system is a splendid choice for your home and a worthwhile investment. It offers many benefits, and you can enjoy them all for years to come if you maintain the system on a consistent basis. You definitely want to protect your investment. By not keeping up with the regular maintenance, you will shorten your system’s lifespan and greatly reduce how well it functions.

What You Can Do on Your Own

While you do need to schedule a regular cleaning and checkup for your unit with a professional at least once a year, like with our skilled technicians at AA-AIR Company in Knoxville, TN, there are some things you can regularly do on your own to tend the maintenance of your unit. Take care though. You must turn off your system completely, both indoor and outdoor components, and let them sit for about an hour before you begin. Also turn off the outdoor circuit switch to prevent electric shock:

  • Check to be sure both the indoor and outdoor units have ample unobstructed space in their surrounds, at least a four-foot clearance, to give them room for appropriate airflow and to do their thing.

  • Clean both the indoor and outdoor units. For the indoor, take a damp, soft, white cloth and wipe it down. (Be sure to regularly dust the unit to avoid any significant dirt buildup.) For the outdoor unit, you’ll be cleaning the condenser and coils. After being sure the component is off, along with any electricity, take your garden hose and gently squirt it down. Be sure you don’t use a hose nozzle, as that can apply too much pressure and bend the fragile fins. You just want to rinse off any dirt or debris. If you maintain this task monthly, it’ll be much easier to clean and will work more efficiently. After rinsing the unit, wipe off any leftover residual dirt and dry the unit completely, again taking care with the delicate fins.
  • Remove the filters from your indoor component, and vacuum them thoroughly. This should be done every four weeks, but if you have allergies, pets, or smokers in your home, you might want to check them more often. If your filters are too dirty to vacuum clean, you should probably replace them, then get on a regular schedule of cleaning them. Your filters are one of the most important parts of your ductless system, as they protect both your system from dust and debris accumulation.

What a Professional Will Do

There are definitely things a trained professional will address that you as a homeowner should not. Some of the things checked at your annual maintenance appointment are coolant levels, as well as electrical connections and run capacitors. If anything needs repairing or replacing, your technician will bring it to your attention.

Your ductless system will last for years to come if given the maintenance attention it needs. If you’re considering purchasing a ductless system, schedule service online today, or call and speak with one of our professionals at 865-689-5290 — we’re always happy to help!
