Best 4 Zone Mini Split In 2022

Do you have rooms in your home that are always hotter or colder than the rest of the home?

While there are many reasons for this problem, one of the major causes is having an undersized or oversized air conditioning or heating unit.

I have a solution for you – mini-split systems. The best 4 zone mini split heat pump is the solution for keeping your home comfortable all year round without facing temperature inconsistencies.

A 4 zone mini split has one outdoor compressor unit and four air handling units. You can control each room individually because each indoor unit has its own thermostat.

If you don’t have four rooms to cool or heat, you can choose a single, dual, trio, quint zone, or even more. The advantage is that these units are very quiet and require much less to operate.

Are Mini-Splits Worth the Money?

If you happen to have a central air conditioner working at all or no AC in your home, you know how the summer heat can be unbearable. If you’re going through this issue, then mini splits are the right solution to consider.

Compare to other systems, mini splits offer plenty of benefits such as efficiency, easy installation, and quiet operation. Thus, they are some of the most reliable and durable air conditioning systems to consider using in your home. 

Ductless ACs are quite versatile. Regardless of how large or small, your home is, as well as the cooling requirements, mini-splits can be easily installed to effectively and conveniently cool the home and offer you a comfortable environment. It’s also crucial to note that mini-splits are designed to expand, making life easier for you if you have an attic or basement or add another room in your home. 

So, are mini-splits worth the money? Absolutely! Mini-splits are worth every dime you use to buy them because they offer a wide range of benefits and make life easier for you. They are not only easy to install but also quite affordable. However, the installation cost will depend on the mini-split unit’s size, your home size, and the brand you buy. 

How Many Zones Can a Mini Split Have?

When researching mini-splits, you’ll keep coming across the word “zone’ and wonder what it may mean. These are generally referred to as single zones, and there are also upward zones such as two and above.

If you’re planning on buying mini splits for your home, it’s important to understand the zones, what they mean, how many zones a mini-split can have, and the ones suitable for your needs.

To simplify this whole thing, what you need to know is that mini splits can be categorized into two:

A single zone mini split only uses one ductless mini-split system with a unit for outdoors and indoors. The system is installed in one room of your home or workplace. The room where you install the unit may have specific heating or cooling need currently not met.

However, using only a single zone unit means that other rooms in your home won’t benefit from the more regulated temperature control.

Things are different with a multi-zone mini split because it features a compressor that attaches to many indoor units that may have. The fewest units you can buy for a multi-zone mini-split system is two, although some people may use as many as five. Therefore, to answer this question, you need to know that a mini-split can have eight zones.

To determine the number of units you need for your multi-zone system, you have to count the rooms requiring better heating or cooling, meaning that each room will be considered its zone.

Do I Need a Mini Split for Every Room?

NO! You certainly don’t need a mini-split for every room. When dealing with an old home that features a lackluster HVAC system or even a new home that needs a new system, using a mini-split AC system is usually the best option to consider.

This is mainly because it is both a heating and cooling system smaller than the regular whole-home models. Another benefit is that it is energy-efficient and easy to use. 

You don’t need a mini-split system for every room because it can work properly by itself with another of its kind or even with a whole-home unit. However, if you have a larger home, you may need only a few or use one combined with a larger unit.

But there wouldn’t be any need or reason for you to install all of these units in every room. This makes an energy-efficient mini-split suitable to consider due to its ease of use and efficiency.

Single Zone vs. Multi-Zone Mini Split

A zoned mini-split system provides you with customized comfort and more control over the air quality in your space or room. This is because there can be areas that need less heating or cooling than others. 

Single Zone Mini Split

A single zone mini split system features one air handler and one condenser. It is efficient, minimizes energy usage, and offers better performance. It is also eco-friendly and helps you save money. If you plan to add a room in your home, then a single zone mini split is excellent. 


  • Energy-efficient
  • Low carbon footprint
  • Less equipment
  • Fewer repair and maintenance needs
  • The option to buy efficient models for each area

Multi-Zone Mini Split

Installing a multi-zone mini split requires only one condenser to manage several indoor handlers. A single condenser can handle up to 8 indoor units. Therefore, this can be a solid option for a multi-story house. Having a multi-zone mini split setup reduces the burden and enhances comfort. 


  • Cheap to maintain
  • It offers you complete control over the cooling and warming throughout your home
  • Fewer outdoor units
  • Remote management of the system

Differences Between These Two Options

The difference between a single-zone and multi-zone mini split is the price, number of components, and installation. Single zone mini splits are cheap to install due to the number of indoor air handling units you need.

What’s the Best Option?

Choosing between either of these two options will depend on your needs and situation. To make the right choice, you need to determine your room’s size, installation, costs, and many other factors involved. Therefore, once you’ve determined all these things, you’ll be in a better position to make the right selection.

Tips to Maximize Comfort and Savings with Mini-Splits

 Here are some of the tips that you can use to maximize comfort and savings with mini-splits:

  • You first need to understand when you need to use your backup heating source because not all mini splits are designed to use in cold climates. Therefore, you need to confirm this about your unit.
  • Set the temperature sensors on your mini-split unit to achieve optimal comfort. If these sensors on your unit are higher up than where the thermostat usually would be, it means they are located near the ceiling, where the air is warmer. 
  • Ensure you maintain your indoor unit properly and prevent the winter’s wrath from doing damage outdoors. You can do this by cleaning the filters on the indoor units often. There’s an indicator that alerts you when the filters need cleaning.
