The Pioneer Ceiling Cassette AC is very high-powered, but expensive.

It’s one of the most powerful on the market —  it can cool (or heat) large rooms within 10-minutes.

There’s many BTU sizes available:

One of my favorite features of this unit is the washable filter.

You can just put it under cold water to remove any residue that might’ve gotten stuck — you’re also able to reuse it multiple times without worrying about causing damage to it.

** Washing your ductless air conditioner consistently every year will help it last longer and require less energy. In the long run it’ll keep your electric bill lower than non-Pioneer ACs.

#4.) Pioneer Wall Mount AC System

PIONEER Air Conditioner Inverter

This Pioneer AC system comes w/ an inverter compressor for maintaining consistent temp.

Instead of having to restart it completely, the air compressor will keep working and do the job for you — this significantly reduces the amount of energy needed for cooling.

Multiple sizes available.

It’s a single point power unit with a compressor located on the outside part.

It produces minimal sound when it operates. That’s a huge plus if you’re running it in a bedroom or work office!

What separates this unit from other air conditioners is that all the systems’ performances are safety tested and approved.

#5.) Pioneer Cassette AC System

PIONEER Ceiling Concealed Split

Check Price Button

This Pioneer ceiling unit provides consistent cooling for efficiency.

Instead of turning on and off, multiple times – the Pioneer Cassette stays balanced.

It’s a little different which can be good for some and inefficient for others. If you have limited rooms your home, it might be a good choice (because someone is present more often).

If it’s for a room that’s not frequented as much, I’d advise against it.

Another downside is that it’s a little slower to cool — it’s best to leave the unit running.


  • Cooling capacity:  24,000 BTU 
  • Heating capacity:  24,400 BTU
  • AC system sizes: 5
    • 9,000 BTU ; 12,000 BTU 
    • 18,000 BTU ; 36,000 BTU
    • 48,000 BTU
  • Easy-to-wash filter
  • Fresh air intake option

Potential Flaws

  • Few buyer reviews

#6.) Pioneer 4 Zone Mini Spit AC System

PIONEER Multi Split System

Check Price Button

This Pioneer AC system is best for cooling/heating multiple rooms in your home.

It comes w/ a complete DIY installation kit — buyers say it took 2 people to connect throughout the house, but was fairly simple.

It’s a little bulky/heavy which is why 2 people will likely be needed.

Each mini split has its own remote control.

  • Cooling capacity:  19,900 BTU

As we approach the last days of summer, it’s important to find the right Ductless AC Inverter that’s durable enough to last the next 3+ years.

Fortunately, Pioneer is known for producing durable AC units that include a Heat Pump for winter time! Using the remote control

According to buyer reviews, Pioneer Air Conditioners are fairly easy to install. You’ll need a helper of some sort, but it’s definitely cheaper than buying an entire AC system + hiring HVAC contractors.

Another benefit is that most come with a heat pump for when it gets colder. The remote control makes it super easy to control the heater or AC from a distance.

Prices have dropped and they’re a very effective solution against extreme colds and unbearable heats. (most are air conditioners + heat pumps)
