Why a Ductless Wall Mounted AC Unit Makes Sense For Your Home

A wall mounted ac unit is an abbreviated way of saying ductless mini-split air conditioning system. These units have become very popular over the years for how easy they are able to be installed in spaces that previously would’ve needed major work to get air into, along with how affordable they are. 

These wall mounted ac units have the capacity to bring either air conditioning, heating or both(!) to a location in your house that’s not part of your homes HVAC system. 

For homes that are going through a light remodel, where the homeowner is updating a kitchen, living room or any other space that wasn’t part of the homes original HVAC system which used existing duct work to force air into spaces, installing these ductless mini-split ac units is a way to potentially save money and time while gaining the benefits of adding heat and air conditioning to much needed spaces.  

As you can imagine the concept of of these units is to work by bringing either cool air or heat to locations without relying on the use of ducts in the process.

A wall mounted ac unit is one of the most flexible and convenient solutions at handling any indoor air issues that can be easily solved by bringing air directly into a space without making any major inconveniences to your life. Installing one will usually take a day for an installer to handle which compared to the alternative of extending your existing HVAC systems duct work really leaves you with an easy choice since adding to an existing HVAC situation can be costly and complicated.

By installing a ductless mini split system you can cut costs dramatically while ensuring instant relief to a specific location. Best of all, these appliances can provide an all year round comfort while also being the more cost-effective when it comes to your energy bills. Units usually come with remote controls that can be affixed to a wall to ensure they aren’t lost, and when the unit is needed you can turn on, and when you leave the room it can be turned off. It works in similar fashion to window air conditioning or portable heater units, only more convenient and powerful.

Below we review six ductless wall mounted ac units we recommend. We believe these models will give you the results you’re looking for, and won’t break the bank!

How Do Ductless Mini Splits Work?

Ductless mini-split systems are actually the most unique of appliances. A hybrid model they combine that of a heater and a central air conditioner. This unique function further extends to its overall construction.

A ductless mini-split is made up of three main components:

  • An outdoor condenser – This works to pump air inside of the system
  • An indoor unit – This can be wall or ceiling mounted and works to release the air
  • A conduit – This joins both indoor and outdoor sections together. It does this via a network of power supply, cooling tubes and condensate drain.

The Gree makes good use of G10 inverter technology. The result is an appliance which actively works to save you energy, reduce outdoor noise, and keep your room temperature steady.

This steadiness is further enhanced by the appliance’s ability to eliminate those harsh starts and stops that you may often find in several conventional systems.

Whisper quiet in performance, the Gree ceiling cassette can be operated employing an infrared wireless remote control or alternatively wired controller which is mounted to the wall.

Perhaps the best quality of the Gree though has to be its self-diagnostic system. These units will all run both indoor and outdoor continual tests on the system. This means that should any unacceptable operating condition become flagged, the system will rectify it or stop if for you to further investigate!

What to Consider Before Buying a Ductless Mini Split

Before you spend your hard-earned money on a ductless mini split, we recommend considering the following few points:

  • How many zones will your appliance need to cater to?
  • What are the sizes of the rooms you want to cool or heat?
  • What power/BTU do you require?
  • What is the SEER rating of your appliance?
  • Is your appliance a quieter runner?
  • What is the voltage?
  • How easy will the installation be?
  • Do you require additional support or a warranty?
  • What are the potential running costs?
  • What additional features and benefits would you prefer?
  • What is your budget?

Additional Ways to Keep Your Energy Bills Down

With many household consumer reports suggesting that one of the largest utility bills for many households is for heating and cooling purposes, here we offer some simple tips to help you keep those energy bills low:

  • Be sure to service your ductless mini split regularly. Sometimes a little bit of maintenance can make the biggest of differences. This is especially so when it comes to cleaning the filter.
  • Try to reduce the AC level at night. The cooling temperature required at night is a lot less than that of during the day. So, if you need to use your appliance at night, remember to turn it down or look out for those models offering a sleep mode for this very purpose.
  • Turn off lights – Though it may not seem like it, lights can indeed warm a room. Thus, if you don’t need them on, make a point of turning them off, especially during the day and when going to bed.
  • Keep a fan to hand – Even when you install a ductless mini split, having a fan will allow you to decrease the amount of air that needs pumping into your room. Therefore, you can alternate between the two for optimal comfort but ultimately reduced energy bills!

Frequently Asked Questions

How do I maintain my AC Unit?

AC units need to be regularly cleaned for dirt and debris. This means not only doing visual checks of the system but cleaning, washing, and replacing filters, examining the coils and fins, and brushing them softly, as well as ensuring the unit remains sealed throughout.

What extras features should I consider for a ductless mini split?

Though additional benefits of these models may be a more personal preference, ideal features can include a dual-zone operator that allows both cooling and heating properties. Additionally, remote controls are the most convenient, as are programmable timers. Those units with reusable filters will also actively reduce costs over time.
