Who Should Buy a Mini Split AC
Mini split ACs are a great solution for anyone who is looking to add climate control to large or small spaces. If your home is lacking proper climate control in specific rooms, small mini split ACs can supplement your existing system or satisfy all of your heating and cooling needs on their own.
A new structure will require a modern climate control system, and mini split ACs are the ideal choice for a new shed, garage, or workshop. Traditional HVAC systems can be bulky and overly powerful for smaller structures. Mini split systems come in a wide range of power options, and they’re all much smaller and often more efficient than a full-powered HVAC system.
Commercial facilities can also benefit from the efficiency of an easy-to-install mini split AC system. Ductless and ducted options are available, and some slim fitting mini split AC models were designed specifically for light commercial spaces where there is little room to spare for ductwork.
If you’re finding your home struggles with humidity and you want to address that problem specifically, you may want to consider investing in a dehumidifier. For that purchase, you’ll definitely want to take a look at The Best Dehumidifiers.
Important Features to Consider
There are a few important considerations to think through before purchasing a mini split AC.
- BTU power. The British Thermal Unit (BTU) is a unit of heat often used to determine the power of a heating or cooling device. Every mini split AC has a BTU measurement that equals its power output over the course of an hour’s time, and sometimes you will find two listed BTU measruements— one for heating and one for air conditioning. This unit is often paired with a square footage measurement that the mini split AC is capable of maintaining a steady temperature within. It’s important for you to know your space’s square footage, and the unit’s BTU power, before purchasing a mini split AC.
- Zone control. Now that we’ve established how big of an area we want to heat and cool, we need to know how many zones, or rooms, require climate control. While one powerful mini split AC is capable of heating and cooling multiple rooms, it is much more efficient to have a separate unit for each room, or zone, to reduce power consumption and long-term costs. As an alternative, ducted mini split ACs can be quite efficient at heating and cooling multiple climate zones in a space with many rooms.
- Ducts or no ducts? Most people won’t want to deal with ductwork, and to reflect that we have primarily outlined ductless mini split ACs on our list. However, more powerful systems, like those needed for large homes and commercial use, often require ducts to facilitate the power and airflow necessary for proper climate control. How big of a climate control system do you need?
Frequently Asked Questions
What is a mini split AC and how does it work?
Mini split ACs are heating and cooling systems that enable a person to control the temperature in a single room. The system is split into two main components— an outdoor condenser and an indoor evaporator. The indoor segment is where hot or cold air is circulated into the household.
These mini split systems are often ductless. They can serve as supplements to larger HVAC systems or as a complete climate control solution for small apartments and individual spaces. They are small, relatively easy to install, and energy-efficient. Most are operated via an interactive panel or proprietary remote control, but some can be connected to a smart thermostat or controlled through a smartphone app. Ducted mini split ACs are ideal for larger spaces with multiple rooms and act more like a central air system.
Are mini splits better than central air?
Mini split ACs are better than central air for small spaces and multiple zones where individual climate settings can be applied. Often, mini split ACs are installed in places that don’t require the immense needs of a large central air HVAC system. They can also be ideal for certain commercial needs where specific areas require different climate settings than others. Ducted mini splits bridge the gap between ductless mini splits and central air units, and are usually powerful enough to service an entire home.
Do you need a mini split in every room?
Not necessarily, though a mini split in every room, or a ducted mini split AC, would be more efficient. Powerful mini splits can be capable of heating and cooling a large space, but the circulation between rooms will not be all that great. A one-bedroom apartment or small office may fair well with a single mini split, but a large home with multiple bedrooms would be better off with a mini split in each room.
Can a mini split heat or cool a whole house?
It is possible, but as stated in response to the last question it is more efficient to have multiple mini split units in larger homes. More units would control a home’s climate more efficiently, leading to less energy consumption and a smaller energy bill. A ducted mini split may be the preferred way to go for a large house with many rooms.
