Is a Ductless Mini-Split Air Conditioner Worth It?

A ductless mini-split air conditioner is supposed to be a great way to stay cool during a hot summer, but are they really worth the money? Window air conditioners are way cheaper. What advantages will a mini-split deliver that a simple window unit can't?

Ductless Mini-Split Air Conditioner Advantages

As it turns out, there are a lot of reasons to get a mini-split air conditioner over an old fashioned window unit. For starters....

Cost. Now, I'm not talking about price, because window units are certainly cheaper. However, that low price tag comes with poor energy efficiency. Which means that while a mini-split costs more up front, it will save you a lot more money over time.

Comfort. Effective air flow is an important component in determining interior air comfort. Placing your air conditioner for optimum air distribution is key. With a window unit, you don't have much choice. You either put it in an available window or cut a window unit-sized whole in your wall. Ductless units are much more flexible. They can go on just about any interior wall, and only need a small 3" hole to connect to the outside.

Quiet. On any air conditioner, the compressor is the loudest part. With a window unit there is no getting around the fact that the compressor is always in the same room with you. You don't have to do that with a mini-split. You keep the compressor outside between an insulated wall and you.

Convenience. Windows are much easier to look out of when a bulky window air conditioner isn't blocking your view. A ductless mini-split air conditioner means you don't have to sacrifice a window for your comfort. The mini-split air handler will be mounted up on the wall out of your way.

    If you want to install just one air handler, you might find that a single-zone system with an 18k BTU air handler could work well for your setup. Keep in mind that sizing correctly depends on climate, sun exposure, insulation quality, and a number of other factors.

    Would a 15,000 BTU one head ductless mini split heat pump work for a 675 s.f. home with 2 bedrooms/1 bath? Is the condensate line draining under the house on a raised foundation a good idea?

    It could work, depending on factors such as climate, insulation, sun exposure, and a number of other variables. We would recommend that the condensate line drain away from the house.

    I want to power a minisplit system for three rooms with a backup honda generator model eu7000is. How many watts does this system use?

    If the system you are looking at is the three zone DIY multi zone system that uses the Multi3-27 condenser, the minimum amps is 21. The watts are 4700. If the system uses the Multi4-36 condenser, the minimum amps is 30 and 6700 watts.

    What if I need to place the indoor unit more than 25ft away from the outdoor unit?

    Mini-split lines can be modified to reach farther than 25'. If you're talking about the DIY and its 25' line, you can extend length with a coupler kit.

    There are tools that can cut through brick.

    Can these units provide 72 to 75 degree room cooling in desert areas where outside temps can reach 115 degrees?

    Properly sized for the climate, certain ductless mini-split models could operate effectively in desert areas.

    Does this unit only allow for one indoor evaporator or can multiple evapertors be conne ted.

    Many ductless mini-splits allow for only a single indoor evaporator connected to an outside condenser. However, multi-zone units like the Olympus can accommodate multiple indoor units on a single condenser.
