12,000 BTU Mini Splits Buying Guide

If you have decided to invest in a 12,00 btu mini split system, and you have the right measurements for your room, there are very critical factors you have to keep in mind during your search to help you find the perfect unit for your home.

But first, how do ductless mini split air conditioners work?

How do Ductless 12,000 BTU Mini-Split Air Conditioners Work?

Ductless mini split air conditioning units have two main parts – an outdoor and indoor unit. Air conditioning or heating starts on the inside, with the indoor unit designed to blow warm air from your home over cold evaporator coils. The refrigerant running through these coils absorbs the heat from the air and transfers it into the outdoor unit, which then dumps it to the outdoors.

The difference between mini split air conditioners and central units is that the latter has the indoor unit located in the attic or closets. Air pulled from your home is carried to this central location for cooling after which it is sent back your home through another duct.

This process is different in mini-split air conditioners because the indoor unit is usually placed in the room that you want to cool. This is a great advantage because you don’t need air ducts. The unit simply receives all the heat from the rooms, dumps it outdoor and blows cold air from the outdoors into the room.

There are different types of mini-splits, with the most common types being wall-mounted, horizontal ducted, floor-mounted, and ceiling-mounted models.

Benefits of Mini Split Systems

Ductless mini splits offer homeowners many benefits. If you haven’t installed these units, here are some benefits you may be missing out.

  • Flexible control: Ductless mini split air conditioners are invaluably flexible. Their unique design and small size make them ideal for zoning or heating and cooling individual rooms. If you have five rooms that you’d like to control separately, for example, all you have to do is find a mini split with five air handlers. This way, you’d be able to turn ON or OFF air conditioner or heat or adjust the temperature in each room independently. This is impossible with central air conditioners.
  • Easy to install: Ductless air conditioners easy to install. For starters, you only need a small hole (around 8 cm) through the wall to connect the indoor air handler to the outdoor unit. The units, however, come with long connecting conduits, allowing you to position the indoor unit as far as 50 feet (around 15 meters) from the outdoor unit.
  • Reduced energy losses: Since ductless mini splits don’t require ductwork, energy loss is also minimized. Poorly insulated ductwork contributes to approximately 30% of energy loss in central air conditioners. Leaking ductwork could lead to even higher energy losses. Ductless air conditioning systems eliminate this problem.
  • Flexible installation: These units also offer the kind of installation flexibility not available with other air conditioning systems. For example, the indoor unit can be suspended from the ceiling, hung on a wall, or flush mounted onto a drop ceiling. Then, there are also floor-standing models. Plus, since you only need a small hole through the wall to connect the indoor unit to the outdoor components, mini splits leave your home safer. Window-mounted air conditioners, in comparison, for example, can provide an easy entry for intruders.

What Size Ductless Mini Split AC Do I Need?

12000 btu mini-splits are designed for spaces ranging from 400 to 600 square feet. But, are you making the right choice? Is a 12,000 BTU unit what you need, or do you need a smaller or maybe even larger unit?

This is the million dollar question when shopping for a ductless mini split system. Keep in mind that if you choose a small, undersized unit, it may not adequately cool the space. On the other hand, if it’s too large, it would cool the area quickly, leaving behind a damp and clammy feeling. Also, it would cause temperature fluctuations as well as failing due to short cycling.

The best way out of this problem is to ask your HVAC technician to perform a Manual-J Load Calculation test to properly size your ductless system for the space you want to cool or heat.

Additionally, it’s important to apply some common sense. For example, two similarly-sized spaces in different climates have different cooling requirements. The room in a cool climate requires less cooling capacity than the one in a warmer climate. The reverse is true for heating – the room in the warmer climate would need a smaller heat pump. Insulation is another factor. Better insulated spaces don’t need as much cooling or heating as poorly insulated rooms.

How Much Does It Cost To Install a Ductless Air Conditioning System?

Several factors affect the cost of ductless units, among them; quality, performance, efficiency, and single vs. multi-zone configuration. Let’s look at each of these factors more closely;

Quality

Ductless air conditioners are available in a range of quality ratings. The following are the common quality categories;

  • Standard brands: Standard brands are priced moderately and have life spans ranging from 15 to 18 years. Brands that fall in this category include; Haier, Pioneer, GrKingsfin, Classic America, MrCool, Blueridge, and Kilmaire.
  • Premium brands: These are higher priced air conditioners with life spans ranging from 17 to 21 years. Brands in this category include; American Standard, Lennox, Trane, Toshiba Carrier, Friedrich, Fujitsu, LG, Panasonic, and Mitsubishi.

Performance

There are two primary issues to break down here; functions and comfort. With regards to functionality, AC-only units cost less than mini splits that double up as heat pumps. Some mini splits even work as dehumidifiers. These models cost more. When it comes to comfort, some premium mini splits have inverter compressors that are not only more efficient but also quieter and perform more consistently. These units cost more.

Efficiency

The SEER rating determines the efficiency of ductless heating and cooling units. This rating ranges from 15 to 38. SEER simple means Seasonal Energy Efficiency Rating and describes how much cooling can be achieved per unit of energy consumed. As such, higher ratings indicate that the unit is highly efficient. Another efficiency rating that you may come across is the Heating Seasonal Performance Factor (HSPF). HSPF ratings typically range from 9.0 to 15.0. Again, higher values here mean that the unit has high efficiency. More efficient units cost more.

Single vs. Multi-Zone Units

Generally, multi-zone mini splits cost more than single-zone models. On the same note, multi-zone systems can have up to five air handlers, which means they can control the temperature in up to five separate rooms simultaneously. In most cases, the higher the number of zones a mini split can handle, the higher the cost.

Wrap Up

Ductless air conditioners differ from ordinary air conditioning systems. They are energy efficient and doesn’t require ductwork. They also allow you to customize the temperature of different rooms, especially if you choose multi-splits systems. The initial purchase and maintenance cost of these units is also little bit high compared to other air conditioning and heating units. However, they last a little longer and saves a lot of energy in the long run. With all these benefits, we hope you find the perfect 12000 btu mini split for your home.
