A large ductless system with a BTU of 36,000 can effectively cool a room measuring up to 1,500 total square feet, while smaller units usually start at around 9,000 BTUs and can cool approximately 350 square feet of space (the size of approximately 2-3 bedrooms).

How many rooms can a ductless air conditioner cool?

Both can be used to cool a single room without ductwork. But a mini-split can add more evaporator units (up to 4) to one condenser unit. So technically it can cool up to 4 rooms.

How big of an area can a mini split cool?

One of the most often installed sizes is a 12,000 BTU mini-split. This will heat and cool approximately 450–550 square feet, or about the size of a studio apartment.

Will a ductless air conditioner cool a whole house?

Even though it takes a powerful system – especially in a large home – a ductless mini split is up to the task. With the right size system in place, it's capable of cooling an entire house, from the basement all the way up to the attic.

How many ductless units do I need?

Based on the size of your home, calculate the BTU requirements (primary factor). Usually, we use a 20 BTU per sq ft rule of thumb. Example: For a 1,500 sq ft home, you would need 1,500×20 = 30,000 BTU output. You can use one 30,000 BTU mini splits, two 15,000 BTU mini splits, or three 10,000 BTU mini splits.

How many square feet will a 12000 BTU air conditioner cool?

Will mini split cool multiple rooms?

A mini-split system is an excellent option for cooling multiple rooms [max 4] in your home from one condenser. The evaporator unit can be mounted in each room you want to cool. Each evaporator has its temperature control so that you can cool each room to the perfect temperature.

Is ductless AC cheaper than central air?

According to the U.S. Department of Energy, it costs up to 30 percent less to install a central air system than it does a ductless one. However, ductless mini-splits tend to cost less to operate long-term. What's more, they often require less maintenance and repair.

Are mini splits worth the money?

When you consider everything you get in return, ductless mini splits are definitely worth the cost. Not only do you save money upfront, but you do so over the long run as well. If you have questions about the cost of installing a ductless mini split AC system in your home, contact us to schedule a free consultation.

How much does it cost to install a 12000 BTU Mini Split?

The average cost for ductless mini split air conditioning installation costs between $1,700 to $8,500. To heat or cool an average living room alone with a square footage of 350 square feet, a 12,000 BTU ductless AC unit with a 21 SEER rating would end up costing around $3,500 for the unit + installation costs.

How many BTU do I need for a 20x20 room?

As a general rule, a 20×20 feet or 400 square feet room should use a 12,000 BTU or 1 Ton air conditioner. If your room is heavily shaded, you can save cost by using a 9,000 BTU or 0.75 Ton air conditioner.

Can a split AC be used for 3 rooms?

Answer is NO. Similarly from one outdoor unit you can operate only one indoor unit of an AC.

Does a mini split need to be in every room?

You do not need a mini split in every room. There are some rooms in which it is better to have a mini split, and there are other rooms that will never need direct temperature control from a ductless system, such as a bathroom or a walk-in closet.

Should I put mini split in each bedroom?

Do I Need a Ductless Unit in Every Room of the House? No. While you won't need a single indoor unit for every room in the home, the outdoor unit does attach to multiple indoor wall-mounted units. In most homes, this typically means having indoor units in main living areas.

Do mini splits use a lot of electricity?

Mini-splits typically consume far less electricity than central AC and heating systems, making them an energy-efficient alternative. Most of them consume about 600 watts per hour. However, energy consumption varies depending on use, temperature settings, and the unit condition.

How long do mini splits last?

Ductless mini-splits – Like heat pumps, ductless mini-splits can provide both heating and cooling, with a typical life span of 10 to 30 years, except in coastal areas.

Should I replace HVAC with mini split?

Efficiency. Ductless mini splits are also one of the most efficient HVAC options available. Energy produced by central HVAC systems is lost as it travels through the ducts, and this waste is eliminated by ductless mini splits. This heightened efficiency directly leads to significant energy bill savings.

What is the difference between ductless and mini split?

Typically, only one thermostat is used for the entire system, although zoning technology can be utilized. Central systems can run off electricity or gas. Conversely, ductless mini-split systems don't use ductwork to move air throughout your home.

What is the difference between a split system and a mini split?

The central heating and cooling systems that are traditionally used in homes are called split systems because they typically have indoor and outdoor components. A mini split air conditioner also has indoor and outdoor components, but it takes up a lot less space than traditional heating and cooling systems.

How many zones can a mini split have?

Ductless mini-split units are highly versatile, allowing you to create zones for separate temperature controls. One outdoor unit can be connected to up to eight zones, typically enough for the average household.

What happens if you oversize a mini split?

A few things can happen when you oversize a mini-split. If you drastically oversize the unit, the system will short cycle, as it cools too quickly to run in a regular cycle. This isn't a desirable outcome since the unit doesn't have enough time in its rapid cycles to dehumidify the air.

How big of a mini split do I need for 900 square feet?

550–600 square feet = 15,000 BTUs. 650–700 square feet = 17,500 BTUs. 750–800 square feet = 20,000 BTUs. 850–900 square feet = 22,550 BTUs.

How many mini splits do I need for 2000 square feet?

In fact, if you play around with our Mini Split BTU Calculator, that's what you'll find. Zone 1 – 2,000 square foot home: AC needed is 48,000 to 60,000 BTU (if using the ton rating, it is 4 to 5 tons). The heating requirement in the same home in the same location is just 24,000 to 32,000, or almost exactly half.
