Buying Guide

The hunt for the best ductless mini split air conditioner & heat pump can be daunting but having the right information can help you secure a better deal.

Here are the questions to ask:

Single Or Multi-Zone?

Single-zone ductless split systems cools using one outdoor and indoor unit per instance and are preferred in bedrooms or any other room not ducted for regular central air conditioning.

For these, the crucial step is to check the power rating to ensure it can cover your room’s square footage when buying.

Multi-zone mini splits systems aren’t so different from single-zone models but usually cover larger areas in your apartment.

However, each of the indoor units (representing a zone) will connect to the sole compressor unit via the refrigerant lines.

Homeowners lacking central air conditioning will find this suitable as it can cool different parts of the home including multiple floor levels.

Multi-zone models are common in basements, apartments, and commercial offices.

What’s The Best Size (BTU Rating)?

The amount of energy that your unit should generate to cool your space is measured in BTUs (British Thermal Units).
Technically, a BTU is the energy needed to elevate water’s temperature by 1 Fahrenheit and is simply its cooling power.

Now, the BTUs associated with a mini-slit’s indoor unit are enough to point you towards the ability of single-zone models.

Things, however, become a bit complicated in multiple zone systems and here, you have to assess the BTU rating of both the indoor and outdoor units with regard to each zone.

It’s also important to remember that BTU ratings are just estimates and assume 10ft ceilings, proper insulation, and windows meaning that improper insulation, excessive sun, an adverse climate in your regions, and taller ceilings will affect the accuracy.

Something Else

In general, larger spaces need more powerful units which will ,in most cases, cost more.

Lastly, don’t make a mistake of thinking that the bigger the unit the better the performance. Rather, what you need is an optimum size and not necessarily the biggest!

Here is a guide on the recommended BTU rating for specific square feet:

Square FeetBTU Rating/hour
150 – 2506000
250 – 3007,000
300 – 3508,000
350 – 4009,000
400 – 45010,000
450 – 55012,000
550 – 70014,000
700 – 100018,000
1000 – 120021,000
1200 – 140023,000
1400 – 150024,000

Is It Energy Efficient?

Apart from independently controlled cooling for each room, the other major strength of ductless air conditioners is their smart power consumption.

That explains why most are energy star certified.

Now, here the keyword is SEER (Seasonal Energy Efficiency Rating), essentially a measure of a unit’s cooling output (seasonally adjusted) divided by its energy consumption.

The thing is, the higher its SEER rating, the greater the energy efficiency and the more the savings in your utility bills.

What About The Extras?

In terms of additions, some models offer more extra features than others. A programmable timer helps you set your unit to turn on/ off at a specific time. For example, you can program it to activate before you arrive home from work so as to be welcomed by a perfectly cooled home.

The automation also helps save energy.

On the same note, you may find an auto restart very handy since it automatically recalls the previous settings after a power failure. Apart from this being convenient, it helps to shield your circuit breaker and the compressor from premature damage.

Besides the above mentioned, an adjustable airflow is awesome as you will also be in charge of airflow, something important since some rooms may need excess airflow, for example, due to their location not to mention that its normal to have temperature disparities between rooms and/or zones in your home.

Finally, washable air filters are great as you just need to wash them when dirty to restore its best functioning rather than spend on replacement filters- which come with some mini-slits.


If possible, units with additional functions are advantageous. Fortunately, most of the latest units are coming enhanced with more and more functions including dehumidifiers.
