Top Mini Split Inverters for 2022

Ductless mini splits are a great way to heat and cool indoor spaces without the mess and complications of traditional HVAC systems. For most mini splits, installation only requires a small hole to pass the power, refrigerant, and condensation line between the indoor and outdoor unit.

However, mini splits can also cost a pretty penny in utilities, particularly multi-zone units that heat and cool multiple rooms. Thankfully, homeowners can cut down those dreaded monthly bills with mini split inverters.

 

What is a mini split?

A mini split AC unit has the same function as other air conditioners: cooling your home. The main difference is that mini split air conditioners do not rely on ducts, which is why they are also referred to as “ductless air conditioners.”

The cooling (or heating) process happens via two components: an indoor and an outdoor unit. The indoor unit blows the warm air over cold evaporator coils containing refrigerant, which absorbs that heat from the air, and runs it to the outside unit. Through the compressor, the refrigerant dumps the heat pulled from your home’s air.

 

What is a mini split inverter?

Within the mini split systems, there are two types of compressors: rotary and inverter

A rotary compressor runs on a fixed capacity, while a mini split inverter uses only enough power to reach and maintain your set temperature, and then idles at that setting until more power is needed. This results in more efficient operation.

For a more detailed explanation, see our entry What is a Mini Split Inverter?

 

Advantages of Mini Split Inverters

Reduced power consumption

  • Inverters have a variable electrical consumption based on their workload.

Longer operational lifespan

  • Since the compressors are more efficient and don’t have to work as hard, mini split inverters tend to have a longer lifespan than conventional rotary units.

Faster cooling

  • Mini split inverters start off strong, then gradually decrease the power level as the room temperature goes down. This means faster and more consistent cooling.

Long-term savings

  • Depending on the appliance, inverter-equipped units can be up to 27% more efficient than traditional appliances, which translates to lower utility bills in the long run.

How to Choose a Dehumidifier for your Home

Humidity is one of those things that few of us think about, yet play a vital role in our everyday lives. Humidity can affect health, comfort, allergies, and even physical structures. 

When humidity levels get too high, they can lead to a sticky feeling, trigger allergy attacks, and have a detrimental effect on your house and furniture. This is particularly concerning during the warmer months, when humidity levels tend to be high. 

A dehumidifier can help regulate indoor humidity levels and bring it back to a safe level.

 

The Effects of Excessive Humidity

During the summer, the ideal relative humidity (RH) level indoors is 50%. RH levels that that go beyond can have a detrimental effect, such as:

Human body

  • Heavy breathing
  • Wet, sticky feeling on skin
  • Curling frizzy hair
  • Higher risk of asthma and allergy attacks
  • Overheating
  • Possible heat exhaustion or heat stroke

House

  • Peeling paint or wallpaper
  • Wall and ceiling stains
  • Bad odors
  • Support beam warping
  • Wood floor warping
  • Doors and windows may get harder to open or close 

Furniture

  • Wood expansion resulting in damage
  • Misaligned joints
  • Expanding seams
  • Possible splits or cracks

A dehumidifier can prevent these effects by maintaining the right RH levels.

 

What is a Dehumidifier?

A dehumidifier is a device that is designed to remove excess moisture from the air. It does this by using a fan to force air through coils filled with coolant, thereby sucking moisture from the surrounding air and turning it into water that can be collected and disposed of. The resulting dry air is then circulated around the room or house.

There are two methods of dehumidification:

Condensate dehumidifiers – these use a miniaturized refrigerator to collect the condensate. These are typically found in larger dehumidifiers.

Desiccant / absorption dehumidifiers – these use hydrophilic materials like silica gel contained in a cartridge to suck the moisture from the air.

 

What are the Different Types of Dehumidifiers?

  1. Dehumidifying Ventilator

As its name suggests, this humidifier uses an exhaust fan to expel air outside. A sensor detects the humidity levels and regulates the moisture by forcing air out. They are often used in basements, attics, and crawl spaces.

 

  1. Chemical Absorbent Dehumidifier

Also known as desiccant dehumidifiers, they use hydrophilic materials to bond with the moisture in the air. The hydrophilic material is often contained in a cartridge that can be refreshed and disposed of as necessary.

 

  1. Heat Pump Dehumidifier

Commonly found, these use a fan and heat pump to remove the moisture. The fan forces air through heat exchanger coils to suck out the moisture and turn it into condensate, which is then collected into a drip compartment or pumped away. Because of their larger size and complexity, they are more expensive than absorbent dehumidifiers, but do not require cartridges.

 

  1. Homemade Dehumidifier

Unlike most home appliances, a dehumidifier’s function is simple enough that it can be copied via DIY. These can range from simple absorbers like rock salts and silica gel placed in the room to more elaborate devices that use fans combined with damp meters or hygrometers to measure the humidity level in the room.

 

Type Cost Ideal Use
Dehumidifying Ventilator Medium (requires installation) Basements, attics, crawlspaces
Chemical Absorbent Dehumidifier Low Single rooms
Heat Pump Dehumidifier Medium (may be high for units that require installation) Single rooms, Basements, Whole house or larger spaces
DIY Dehumidifier Low (depending on design and complexity) Smaller spaces or barely used rooms

A Guide to LG Inverter Air Conditioners

With the ever-rising prices of utilities, inverter air conditioners provide a cost-efficient way of cooling your home without breaking the bank. And LG’s line of inverter ACs combine the benefits of inverter technology with the expertise and durability of one of the world’s foremost appliance brands.

 

What is an Inverter Air Conditioner?

Conventional air conditioners run on a fixed capacity: they are either off (0%), or on (100%). This means it’s always running at its highest capacity, which makes it inefficient.

An inverter AC is able to adjust its output capacity to suit the cooling need. The inverter directs the compressor unit to either increase or decrease the output based on the room’s air temperature, instead of blasting away at full volume all the time.

 

Advantages of Inverter ACs

Reduced power consumption

  • Inverters have a variable electrical consumption based on their workload.

Longer operational lifespan

  • Since the motors or compressors are more efficient and don’t have to work as hard, inverter air conditioners tend to have a longer lifespan than conventional AC units.

Faster cooling

  • Inverter ACs start off strong, then gradually decrease the power level as the room temperature goes down. This means faster cooling.

More quiet

  • AC units tend to be noisier on higher settings. Inverter ACs can lower their setting when the room temperature is cool enough, which makes them more quiet.

Long-term savings

  • Depending on the appliance, inverter-equipped units can be up to 27% more efficient than traditional appliances, which translates to lower utility bills in the long run.

 

LG’s Inverter AC Technology

LG’s line of inverter air conditioners combine inverter technology with a variable speed compressor. This adjusts the speed of the compressor motor to more accurately regulate room temperature compared to traditional air conditioners, which can only turn the compressor on or off.

The result is a quiet, more efficient, and longer lasting AC unit that also boasts higher energy savings. In fact, LG inverter air conditioners can save up to 70% more in energy consumption, based on testing by third-party laboratory Intertek on LG’s LA200WC AC model.

Compressors are one of the most critical elements of air conditioners. Unlike most other brands that outsource their compressors, LG manufacturers its own compressors in-house with LG’s very own parts.
