Your Guide to Buying a Mini-Split Air Conditioner Yehudah Posnick

A mini-split air conditioner is a device that can cool several rooms in your house. It is a cheaper alternative to central air conditioning, where you have to install a system of ducts connecting all the rooms together. (Another problem with ducts is that there tends to be air leakage, which affects the unit’s efficiency. With a ductless model, you avoid all of that.)

What can you expect with the installation? There is usually a single outdoor condenser unit, which expels the hot air from your home, and several evaporator indoor units, where you install one unit in each room. You can then cool individual rooms to your preferred temperature--there is typically a remote control for each indoor unit, to control temperature and fan strength. Many mini-split air conditioners serve as heat pumps as well (at least as long as the outdoor temperature doesn’t go below 25 degrees Fahrenheit), so you have a solution for both winter and summer in one device.

We’ve composed this buyer’s guide to help you make the right decision when selecting a mini-split air conditioner. It'll help you:

  • Choose the right type of mini-split air conditioner,

  • See useful tips about that particular type of mini-split air conditioner,

  • Read reviews of different mini-split air conditioners, and what customers are saying,

  • Select the right brand of mini-split air conditioner, and

  • Compare prices and find the best deals.

Types of Mini Split Air Conditioners

We can distinguish between different mini-split air conditioners by how you mount the indoor unit:

  • Wall Mount--This is the most popular method since the indoor unit can be installed in a way that it is not conspicuous.

  • Ceiling Mount--This model is attached to the ceiling, either suspended or recessed in the center of the ceiling, or adjacent to one of the room’s walls. When in the center, it will deliver hot or cold air evenly throughout the room. But if it is mounted to the side, it will be less noticeable.

What Reviewers Say

  • Match the unit to your room size: If a mini-split air conditioner is stronger than the room’s needs, it will reach the desired temperature too quickly, and then shut itself off. This short cycling actually wastes energy instead of saving it, and puts a needless strain on the unit. So, you should make sure that the air conditioner’s BTUs match the room size. These are useful specs for reference:

    • Room size from 250 square feet - 450 square feet: 9,000 BTUs

    • Room size from 550 square feet - 800 square feet: 12,000 BTUs (best for two-story home, bungalows, side-split, split entry, rec rooms)

    • Room size from 750 square feet - 1100 square feet: 15,000 BTUs

    • Room size from 850 square feet - 1250 square feet: 18,000 BTUs

Note: These figures are when the unit is used for cooling. If it can be used as a heat pump, the appliance will usually prove to be even more efficient.

  • Some things to consider about the installation:

    • Tubing: Take note of the tubing that comes with the unit. Some companies provide 16 feet or 25 feet of copper tubing. This allows you to set up a line set connecting the indoor and outdoor units.

    • The hole between the indoor and outdoor units: You will also have to prepare a hole in the wall or ceiling through which to run the tubing. A 3”-diameter hole will usually suffice. A wall sleeve, usually made from polypropylene, is inserted into the hole, through which you thread the tubing.

    • Coolant: Regarding the coolant, you’ll see that some companies, such as Air-Con, will sell the outdoor unit “pre-charged”, supplied with environmentally-friendly R410A coolant, that doesn’t damage the ozone layer. However, if your unit is not pre-charged, you’ll need a HVAC professional to fill the appliance with coolant.

Important Features

  • Noise: Mini-split air conditioning units can have the outdoor unit separated from the indoor unit by over 16 feet. So the outdoor unit can be noisier than the indoor unit, and still not cause you much of a disturbance. The outdoor unit of the Innova 12000 BTU Mini-Split Air Conditioner operates at around 54 decibels, which is the level of normal room conversation, or a light rainfall. The indoor unit is much quieter, as only 19 decibels--that’s the equivalent of people whispering, or a ticking watch! You don’t have to worry about the air conditioner disturbing your sleep.

  • Warranty: A mini-split air conditioner unit is a big investment--for example, the Senville 24,000 BTU unit is over $1400--so you want to make sure that it has an extended warranty. The Senville has a 3-year warranty on the parts, and a 7-year warranty on the compressor (which does most of the cooling work).

  • Specifications on air conditioners: You’ll see a few acronyms that will help you know about the efficiency of the air conditioner that you select.

    • AHRI certified: You’ll see that air conditioners advertise to be “AHRI certified”. “AHRI” stands for “Air Conditioning, Heating, and Refrigeration Institute”. They compare the performance of air conditioning and heating products, to make sure that they comply with efficiency standards.

    • SEER: The SEER ( = Seasonal Energy Efficiency Ratio) rating tells you how well your air conditioner cools. It is a ratio of the amount of cooling that the appliance performs per unit of energy that it uses. It is measured at a standard of 82 degrees Fahrenheit, and the minimum SEER rating is 13.  The Cooper and Hunter 2-Zone air conditioner has a SEER rating of 21.3.
