Ductless Air Conditioner Buying Guide: What to Look for Before Purchasing?

Whether you’re going to purchase one of the best ductless ac units as reviewed above or some other ductless AC that is not in the review, there are various factors you should consider. Here are a few of these factors:

Initial cost

When dealing with figures that are spread out between around 600 and 5000 bucks, it’ s only natural that you want to consider your options carefully. The most affordable models go for around 600 to 800 dollars but if you want a highly efficient model, expect the price tag to be well over a thousand dollars.

While considering the price, you also need to think about the size of the room where you’re going to install an AC. If it's just a small room, a small, less expensive model will do. If, however, it’s a large room, then a larger, more expensive model might be more appropriate.

With basic engineering skills, installing a cordless mini split system shouldn’t be very difficult. Here’s a video you might find helpful. However, if you find the process to be confusing, you can always hire an HVAC specialist.

FYI: the initial cost of ductless AC units is typically higher than that of window air conditioning units. Nevertheless, window air conditioners consume more energy than the ductless units. In the long run, the energy costs associated with window ACs make them far more expensive than ductless units.

The voltage

With regards to the voltage, there are two major options – 115V and 230V.

Most mini split ACs use the 110 to 120V that the regular outlet presents but some bigger models need an outlet with 220 to 230 volts.

The smaller models using 110 to 120 volts supply a BTU of around 12000 while the larger ductless units using over 200 volts typically supply around 24000 BTU.

And you know what that denotes? It’s simple – a larger unit that uses more volts has more cooling capability than the 110 to 120V models.

As a result, the 110 to 120V mini splits are normally used as single zone units for cooling one room while the 220 to 230V models are usable as multi-zone ACs.

Before you purchase a ductless unit, you want to check its voltage and ensure that it matches that of your home. Using a 230V unit on a 120V outlet will likely break the circuit and cause reduced efficiency as well as electrical problems in your home.

Multi-zone or single zone

The question here is – do you have a central air conditioner in place? If you have one, then a single zone ductless AC will do. On the other hand, if you don’t have a central AC, you will need a multi-zone model,so you’re able to control each room’s temperature.

For those who need a ductless AC for an office, a multi-zone AC will be very helpful. You might also find it very useful if you live in an apartment with multiple rooms.

Energy Efficiency

Ductless air conditioners normally use less energy than central units.

To find out the energy efficiency of a cooling unit, we get the SEER (an acronym for Seasonal Energy Efficiency Ratio). This ratio is calculated by dividing the cooling output by the total electric energy input.

A high SEER shows that less power is being used; it’s an indication of high energy efficiency.

Generally, most ductless units have a SEER of 16 to 24, which the least figure being 13. The best models have up to 30 SEER.

Of course, you should go for a mini split with a high SEER if you want to save more energy.

How to Take Care of And Maintain Ductless ACs Properly 

Ductless units are very useful in a range of ways. For instance, they only use little electric power and thus help you pay less in energy bills. However, to keep enjoying the benefits that these units have to offer, there are certain maintenance steps you need to take from time to time.

Of course, there are things you will likely leave to the professionals. But, here are a couple of things you can do,and they will go a long way towards increasing both the lifespan and the effectiveness of your ductless. 

Clean the exteriors

Take a look at the outer surfaces of the AC. Can you see dust or debris? Clean these off. By doing this from time to time (perhaps once a week), you will keep the dust and debris from making their way into the machine and wreaking havoc in there.

With a clean damp towel along with a gentle chemical cleaner, you will be able to clean the exteriors of the air conditioner effectively. Pay attention to all the surfaces, especially the vents, which might act as a good entry point for the dust.

What this simple maintenance does is that it reduces the chances of your unit clogging, and consequently reduces your expenditure on repairs.

Take off the filters

The filters help protect the internal components from dust and debris and if they’re not working properly, your ductless AC will undoubtedly suffer reduced efficiency.

At least once in two weeks, while going about your regular cleaning routine, remove the filters and observe how much grit they have caught. If there’s too much grit, use a soft bristle brush to get the grit off and then wipe the filters down with a towel.

Your manual should have the precise steps for cleaning the filters, including a recommendation on the frequency.

Remember, clean filters enable the release of clean air into your home. In the event that they’re extremely dirty or damaged, consider replacing them to keep your AC working excellently.

Unclog the pipes

A ductless AC is composed of two units – an indoor (evaporator) and an outdoor (condenser) unit, and pipes are used to create a connection between the two.

If the pipes are not checked for a long time, dirt can accumulate in there, and as a result, the pipes can get blocked, reducing the efficiency of the entire installation. Again, there might be leaks in the system.

The best time to check on the pipes is while examining the filters. If there’s dirt, be sure to remove it, and if there are leaks, seal them with a stop leak product or replace the pipes if the damage is irreparable. 

Clean the condenser and coil

Once in a while, perhaps once per month, clean the condenser and coil. Before cleaning these components, be sure to disconnect the power cables. Then, with a garden hose, spray water condenser and coil and afterward allow them some time to dry completely. Wiping down with a dry towel will accelerate the drying process.

If there’s any debris remaining after cleaning with a hose, try removing it with the towel (or a separate towel perhaps).

After this, check the fins and if they got bent while cleaning the coil and condenser, make sure you restore them to their original shape using an alignment comb.

Allow it space

While it is true that ductless mini splits generally occupy less space than the ordinary air conditioners, they still need ample space to work efficiently.

If there are large furniture like couches or cupboards surrounding the ductless unit, there’s the risk of not only dust accumulation but also less air conditioning efficiency as the mini split is obstructed.

We recommend that you leave at least four feet of free space around the ductless unit.

Objects like picture frames and bookcases can lead to the collection of dust, and therefore, you should refrain from hanging these on the wall near the air conditioner.

Remove ice and snow

This especially applies when using an air conditioner during winter or in places that are naturally cold like the north. The problem with ice and snow is that they can clog the unit’s pipes and mess with the electronic parts.

Thus, examine the outdoor part of the unit and remove any ice/snow lodged on its components. You could install a form of shade over the installation to protect it from the falling ice and snow.

Get a professional

There are so many things you can do to keep your ductless air conditioner is good shape. However, when it comes to technical matters, for instance, repairing the electrical parts, you need to get a qualified air conditioner technician, unless of course, you’re very knowledgeable in such areas.

Wondering where to find one? Just search “air conditioner technicians near me”.

You should have a technician inspect your air conditioner at last once every year. Have them look for blocks and leaks in the drain hoses as well as the refrigerant. Additionally, they ought to examine the electrical components, especially the capacitors.

In case anything is faulty, they should repair or replace it to keep the air conditioner working flawlessly.

The Benefits of Using Ductless Mini Split Ac System

As we have already seen, the cost of getting the top ductless air conditioner is much higher than that of getting a regular window-mounted unit. However, there are certain benefits that will make you want to grab a ductless AC for yourself. Let’s explore some of them.

They’re quiet

If there’s something that can really distract your sleep or time for relaxation, it is a window-mounted ac. If you can’t sleep pleasantly or relax properly because of a window ac, it’s time to ditch it for something better – the ductless ac.

Unlike a regular window ac, a ductless mini split air conditioner is so quiet that you will most probably not hear any sound coming from the unit even when standing right next to it.

How does the ductless unit achieve that? The major components are placed in the outdoor part of the unit, and thus the noise is locked out of the house.

Involves a less complicated installation

Both the ductless and the central air conditioners have both an indoor and outdoor part. However, central air conditioners involve duct work that is typically routed along or inside the walls, making the installation process quite complex.

It might be virtually impossible to install a central unit without the services of a professional. Again, as the process is complex, it might take weeks to complete.

A ductless unit involves no duct work; all you have to do is make sure the connection between the outside and the inside parts is secure. Hence, there’s relatively little work to be done. Okay, it might not be little per se, but compared to the work that has to be done when installing a central unit, it’s definitely far less tiring and complicated.

Actually, if you’re keen enough and you take the time to learn the principles described in an instructional video like this, then you will definitely install a ductless unit in a couple of hours. Just be sure to have your toolset and some gloves on hand.

Here’s a bonus point: as you won’t necessarily use the services of a professional to install the ductless unit, that’s money saved.

Note: Below I added a video about installing mini-split ductless ac. You you know in details just watch the video from start to end.

They save energy

The duct work that comes with regulars ACs leads to a loss of around 30% of the energy they consume. Therefore, with a ductless AC, there’s a chance you will save up to 30% of the energy you’d have used on heating and cooling.

Apart from that, you might notice that the SEER rating on ductless units normally ranges between 16 and 24. There are even units with a SEER of 30.

Regular window-mounted ACs, on the other hand, mostly have a SEER rating of between 10 and 18.

Now, remember, we mentioned that the higher the SEER, the lesser energy is consumed.

By simply comparing the SEER figures for the two units, we can clearly see that a ductless unit is more efficient than a window-mounted unit at saving energy.

Versatility in zoning

Unlike the central acs, which regulate the temperature of your entire house even for the rooms that might not need air conditioning, a multi-zone ductless unit regulates temperature only where you want it to.

Haven’t installed a central air conditioner for your home? Consider installing a multi-zone ductless unit to have better control and save energy.

Better versatility with interior design

A window air conditioner can be mounted on – where? Oh yeah, that’s right – windows only. In contrast, ductless units can be mounted anywhere in the room. From suspending them from the ceiling to hanging them on the wall, the options are quite diverse, something we can’t say about the window acs.

The ductless ac blowers maintain a low profile,and with their sleek designs and elegant jackets, they enhance the room’s appearance in an excellently attractive manner.

Better security

The installation point of a window-mounted air conditioner is a sure gateway for intruders. They can easily knock down the unit and enter your house, as the space is big enough to let an adult through.

A ductless unit, on the other hand, uses a 3-inch hole on the wall as the communication between the indoor and the outdoor parts of the AC. Obviously, a human being can’t make it through that space, and what does that mean? Better security from intruders, and greater peace of mind.

Mini Split Ac Safety Issues You Need to Take Seriously

Your split ac unit is connected to your home’s electrical line, and considering that HVAC systems often use a high voltage that could be above 200, it is extremely essential that the installation is done properly. Again, it’s important that you give the ductless ac regular maintenance to ensure it’s working properly and that there are no electrical faults.

Here are some measures to apply for safety and efficiency.

Turn off the unit while cleaning it

In the part about how to maintain the ductless air conditioner, we dwelt a lot on cleaning, as one of the most important maintenance tasks. Sometimes, you’re going to use water or a damp cloth, especially when you’re cleaning the coil.

But remember, water is a good conductor of electricity. Therefore, be sure to turn off the system and disconnect the power to avoid the risk of an electric shock. And, before cleaning it, allow the machine ample time to cool down. Moreover, before turning the unit back on, make sure it is totally dry.

Install a carbon monoxide detector

Carbon monoxide is a gas that’s produced when there’s combustion without adequate oxygen. If there’s a problem with the electrical connection to the ductless mini split, something may start burning,and this gas might get produced.

As you might already know, carbon monoxide is quite toxic, and what makes it especially dangerous is that it can go unnoticed. It is,therefore, vital that you install a few detectors of the gas in your home, especially near where the mini split is mounted.

Don’t forget to maintain the carbon monoxide detectors as required, for instance, by changing the batteries after a specified period to ensure they’re working properly.

Apart from carbon monoxide detectors, you also need to have smoke detectors installed.

Use surge protection

HVAC systems use lots of power compared to other appliances, and because of that, these systems might cause a power surge. Now, the issue is, if there’s a power surge, your split ac unit might get affected, and you might not even notice it. Over time, as more surges happen, the electrical parts of the unit get damaged, leading the whole system to fail.

To prevent all this from happening, consider installing quality surge protection.

Ask for help

Perhaps you’ve just bought a mini split system but don’t have the handy skills needed for installing it. Okay, the machine might have come with an instructional guide and there also videos on YouTube that illustrate how to do it. But, if you’re not used to handling the technical parts of electrical equipment and don’t understand the basics, like telling positive and negative cables apart, installing the split air conditioner will likely be tricky.

Rather than doing guesswork, consider calling an HVAC professional to do the installation for you.

If the system ever develops a problem and you’re not sure what exactly could have gone wrong, refer to the manual for troubleshooting processes or call the manufacturer for assistance. If that doesn’t help, have a qualified technician check and fix the unit.

Frequently Asked Questions (FAQs) 

1. How do mini splits operate?

Otherwise known as ductless air conditioners, mini splits work like central AC units, only without the duct system.There’s both an indoor and an outdoor unit. The indoor unit drives the warm air from the room over the coils, and the refrigerant in the coils absorbs heat from the air and makes it cool before it gets released back into the room.

2. Why are ductless ACs called mini splits?

Traditionally, the central air conditioning units are known as splits, due to the fact that they have both an indoor and an outdoor component. Ductless ACs also have indoor and outdoor parts, though the entire installation normally takes up less space than the central units. Because of the less space, ductless ACs are known as mini splits.

3. How much will I spend on a split ac unit?

Most good ductless ACs go for 700 to around 2500 dollars though there are units that go for over 5000 dollars. Although it makes sense that the higher the price, the better the quality, finding the best is not necessarily about seeking the most expensive. It is rather about examining the features, observing what other users are saying, and actually testing the unit.

4. Are mini splits noisy?

Not at all. One of the reasons why people want to purchase a ductless ac is to wave goodbye at the noise that the central ACs make.

5. How durable are ductless air conditioners?

Given the right maintenance, a good ductless unit can last decades, offering the user reliable comfort through proper heating or cooling. At least, a good ductless should last at least 2 decades but remember, it all boils down to the maintenance.
