7 Best 36000 BTU Mini Splits For 2022

The main advantage of installing 36000 BTU mini splits at your home or office is that you don’t need to pay for ductwork to get enough power to warm or cool your house.

These ductless air conditioners are also energy efficient, delivering a consistent and smooth flow of warm and cool air all year round. Each system can effectively warm or cool spaces between 1,200 to 2000 square feet, with some supporting multi-zone functions. 

Here are 2021’s best 36000 BTU mini-splits worth buying today.

How Many Square Feet will a 36000 BTU Mini Split Cool?

When buying a mini-split for your home or business, sizing the system depending on your space’s size is crucial. That’s because choosing a smaller unit than your space will only result in inefficient operation and an uncomfortable home.

You’ll end up wasting energy and won’t notice the efficiency of your unit. That might lead to cold or hot spots in your room as the desired temperature won’t spread uniformly across the room. 

With a 36000 BTU mini-split, your system doesn’t need to overwork to compensate for its inadequacy. These mini splits can cool or heat spaces ranging from 1,200 to 2000 square feet, although that might be divided across several rooms depending on the unit’s configuration.

For instance, if you have a dual-zone 36000 mini-split, then each indoor unit will pack 18000 BTU each, effectively controlling the temperature of two rooms ranging from 600-1000 square feet. 

Do I Need a Mini Split for Every Room?

While you can’t use a single-zone mini split to condition your entire home’s temperature, you don’t need a mini-split for each room. However, many homeowners use multi-zone mini-splits to control the temperature of each room.

For instance, if you have a 36000 BTU mini-split with three indoor handlers (12000 BTU each), you can control the temperature of up to three rooms independently while using a single outdoor unit.

That means the number of rooms you can cool or heat with a multi-zone system depends on the number of indoor air handlers you have. 

Single Room vs. Multi-Room Mini Split

As the name suggests, single-zone mini-splits only heat one room at a time, while multi-room systems support several rooms. However, the system you choose depends on your unique needs, location, and home insulation.

For instance, a single-zone 36000 BTU mini-split might come in handy for controlling the temperature in large basements or garages, but you can also choose a multi-zone to warm your entire household.

Why Choose a Single-Zone Mini Split?

  • Easy installation – compared to multi-zone mini splits or the traditional duct system, single-zone are generally easier to install. That’s because there are only two main components to set up, and all you need is a 3-inch hole through your wall. 
  • Affordable cost – Due to the straightforward installation process, single-zone mini splits are less expensive to install than other options. Some brands also have DIY options for homeowners to install on their own. 

Why Choose a Multi-Zone Mini Split?

  • Fewer Outdoor systems – Being able to control multiple indoor air handlers using a single outdoor system is the main reason why most homeowners choose multi-zone mini-splits. That eliminates the hassle of installing an outdoor unit in each zone you need to cool or heat. 
  • Improves your home’s exterior appearance – Having multiple bulky outdoor compressor units negatively impacts your home’s exterior appearance. Fortunately, only one outdoor system can serve up to eight indoor air handlers, resulting in a pleasing exterior appearance of your home. 

How many amps does a 36000 BTU Mini Split use?

With a 36000 BTU mini-split being a 3-ton system, it uses about 18.5 Amps to have enough power to heat four separate 350 square feet. The system works at around 220-240 Volts, meaning you’ll need a circuit breaker as required by the building regulation code. 

What size Of breaker do you need for a 36000 BTU Mini Split?

With your AC’s current converted to DC form when it enters the system, your 36000 BTU mini-split will require 220 volts ac. That means installing a double 20-amp circuit breaker in your power supply or panel box to deliver 40 amps of power.

Fortunately, both the indoor and outdoor units pull very little current from your power supply, and that’s why they’re affordable to operate. 

Other Things to Consider when Choosing 36000 BTU Mini Split

Choosing the right 36000 BTU mini splits is about more than picking the right configuration for the size of your rooms.

Besides room size, zoning and BTUs, here are other factors worth considering:

  • Sunlight – If your room is heavily shaded, feel free to reduce the required cooling BTU by about 10%. However, if the room receives a lot of sunlight, you’ll need to increase the BTU required by 10%. 
  • Average Occupancy – When your room is regularly occupied by over two people, consider adding 600 BTU for each additional person. Human bodies also generate heat when together. Therefore it’s worth factoring out when choosing a 36000 BTU multi-zone mini split for your home. 
  • Climate – The climate significantly affects indoor temperatures. As such, you may want to consider a different option if you live in areas with high temperatures compared to homeowners in low temperatures. For instance, if you’re in a location where temperatures exceed 90 degrees Fahrenheit in hot months, your system must be capable of increasing its BTU by 30%. Fortunately, multi-zone systems can do that as they can adjust depending on each indoor air handler’s energy needs.
  • Your Home’s Age – When your home is old and poorly insulated, much energy is wasted in the process. That means you need more BTUs in your system to heat or cool your room. Homeowners with old spaces should consider increasing the estimated BTU requirements by about 30%. 
  • Floor-type – floor carpeting acts as part of your house’s insulation, making it easy to control indoor temperatures. However, homeowners with tile, hardwood, and stone floors will need their system to work more to heat the house. 
  • Room Function – Some rooms like the kitchen require bigger-sized units because they’re quite hard to control the indoor temperatures. That’s because kitchens are open spaces in general, with heat coming from your stove, ovens, and lighting.
  • Light Bulbs – Lights generate heat when turned on, with certain types producing more heat than others. As such, you need to factor in whether you’ve installed many heat-producing bulbs in your house when thinking of sizing. 
  • Door and Windows – whether your windows and doors are properly insulated affects the BTU load of your system. The more the opening in your house, the more likely it is for air to leak and affect your 36000 BTU mini-split system’s performance.
