Factors to consider buying the best Mini-Split Air Conditioner

Before choosing a product on the market, we check reputable brands like Panasonic, LG, and Samsung. There are several brand names in ductless or mini-split air conditioners, such as Della, Pioneer, Senville, etc., that were not familiar to me, but they are still great brands.

Consider these factors before making an online purchase rather than default to a recognizable looking brand.

1. Power Consumption/BTU

A high BTU leads to a larger surface area covered by the model. Whenever you look at a product’s description, you’ll see the unit’s size.

You will be able to see all the available choices for your home, which will help you make the right choice.

You should always add about 30% to the BTUs in a mini-split if you live in scorching areas where temperatures exceed 90 degrees Fahrenheit.

In addition, if you do not have sufficient insulation, you should add 20% more to the BTU amount below.

2. Room Size

The room size is an essential consideration before purchasing a mini-split air conditioning system.

If you purchase one that’s too small, you’ll find it’ll run constantly trying to cool the room to the desired temperature so that it won’t do the job as well.

Think about the amount of insulation in the room and how many zones you want to cool when thinking about room size.

3. Number Of Zones

If you want to use your mini-split air conditioner in multiple zones, you have to consider this.

There is usually only one indoor unit in the ductless system, covering one zone in your homes, such as a bedroom or a small living area.

Most homeowners have many rooms within their houses to decorate. The benefits of multi-zone air conditioners include the ability to cool several rooms at one time.

There are several affordable options on the market for these products that will cover between 4 and 6 zones.

4. Warranty

In general, most mini-split systems have separate warranties for parts and compressors, with the compressor warranty usually longer than the parts warranty.

The best mini split air conditioners have an extended warranty, which gives you peace of mind.

Make sure to check very carefully first to see if DIY installations invalidate warranties!

5. Considerations of Cost

Depending on the unit’s size and features, mini-splits will cost a different amount of money.

However, a ductless system for an entire house will be about 30% more expensive than a traditional air-conditioning system if ductwork is already present.

The ductless system may be less expensive if new ducts need to be installed.

Other Features to Consider:

6. Option For Dehumidification

Dehumidifying modes dehumidify without cooling, so mini-split units follow the same principle.

With a mini-split unit equipped with this feature, you’d only have to get one appliance!

7. Advanced filtration

There are many filters inside air conditioners, but some systems use filters that do a better job than standard ones at removing pollutants.

Mini-split systems require less maintenance and lower long-term costs.

8. WiFi Ready

Looking for a system that comes to WiFi ready if you want to control your split system from the gym, office, or even from abroad.

Most of the time, you need to purchase an additional adapter.

9. Quick cool

Once the desired temperature has been reached, the feature cycles the system on high.
