How Many Amps Does a 36,000 BTU Mini Split Use?

To determine if your electrical system can support a 36,000 BTU mini split air conditioner, you need to know how many amps it requires. Most 36,000 BTU mini split units require 20 to 25 amps to operate, depending on the specific model and brand.

  • A 20-amp, 36,000 BTU mini split would need a dedicated 240-volt circuit to function properly. This type of air conditioner pulls too many amps for a standard 120-volt household circuit.
  • A 25-amp, 36,000 BTU mini split also requires a 240-volt circuit and may need a higher capacity breaker and wiring to handle the power demands. The condenser unit installed outside and the air handler installed inside will each need their breaker and wiring.

What Size Wire Do You Need for a 36,000 BTU Mini Split?

  1. To properly install a 36,000 BTU mini split air conditioner, you will need to use wire that is appropriately sized for the unit. Using wire that is too small can result in overheating, reduced performance, and even fire hazards.
  2. It is recommended to use 10 AWG copper wire for a 36,000 BTU mini split. 10 AWG wire is capable of handling the high current draw required to start and run a unit of this size. You will need to run the wire from your main electrical panel to the outdoor compressor unit and the indoor air handler. The wire must be rated for the voltage required by your specific mini-split model.
  3. When running the wire, be sure to use wire specifically meant for air conditioning units. AC wire is double-insulated and able to withstand exposure to heat and cold. Secure the wire at regular intervals as you run it to the units. Leave some slack in the wire at the units to allow for serviceability.
  4. You will also need a proper disconnect switch to cut power to the mini split for any service needs. A disconnect switch rated for at least 125% of the unit’s amperage rating should be installed within sight of the outdoor compressor. Label the switch clearly as the disconnect for the AC unit.

What Is the Best SEER Rating for a 36,000 BTU Mini Split?

Why SEER Matters

  • A higher SEER rating means the AC unit will use less energy to produce the same amount of cooling. This can significantly lower your utility bills over the lifetime of the unit. A mini split with a SEER of 15 or higher can cut your cooling costs by up to 30% compared to an older unit with a SEER of 10. The higher initial cost of a more efficient unit will pay for itself over time through lower energy usage.

Additional Benefits

In addition to lower energy usage, a mini-split with a high SEER rating provides other

  • It reduces your environmental impact by decreasing greenhouse gas emissions from power generation.
  • It allows for more precise temperature control since the unit does not have to cycle on and off as frequently. This can improve your comfort.
  • It may make you eligible for tax rebates, credits, and incentives for installing energy-efficient equipment. Many utilities and governments offer programs to promote the use of eco-friendly AC units.
  • It increases the resale value of your home. Energy-efficient features are appealing to potential homebuyers.


  • For a 36,000 BTU mini split, choose a unit with a SEER of at least 15 to maximize efficiency and cost savings. Models with ratings of 16 SEER or higher are even better options if your budget allows for the slightly higher upfront cost. By installing an Energy Star-certified mini split AC with a high SEER, you'll enjoy lower utility bills, improved comfort, and the satisfaction of reducing your environmental footprint.

Pros and Cons of a High-Efficiency 36,000 BTU Mini Split

A high-efficiency 36,000 BTU mini split system has several advantages and
disadvantages to consider before installation.


  • Highly energy efficient. A 36,000 BTU unit can provide sufficient cooling for most residential spaces while consuming minimal energy. Seasonal energy efficiency ratings of 20 SEER or higher are common.
  • Flexible installation. Mini-split systems allow for targeted temperature control since the evaporator units can be installed in multiple rooms. They do not require ductwork and are ideal for heating and cooling open floor plans, attics, garages, and additions.
  • Quiet operation. The components of a mini-split system are designed to minimize noise. At full capacity, a 36,000 BTU unit may produce only 45 to 55 decibels of sound, which is slightly louder than a refrigerator.
  • Extended service life. High-quality mini split systems that are properly installed and maintained can function for 15 to 20 years before needing replacement.


  • Higher upfront costs. Although mini-split systems save money in the long run, the initial purchase and installation fees are typically higher than a conventional HVAC system. A 36,000 BTU unit may cost $3,500 to $5,500 to install.
  • Limited heating capacity. Mini-splits are best suited for cooling and heating in temperate climates. A 36,000 BTU unit may struggle to sufficiently heat areas over 1,500 to 2,000 square feet in very cold weather. Supplemental heating sources may be needed.
  • Require professional installation and maintenance. Mini split systems must be installed, serviced, and repaired by licensed HVAC technicians to ensure optimal performance, efficiency, and safety. DIY installation can void product warranties.
  • May not qualify for utility rebates. Some utility companies and local governments offer rebates and tax incentives for installing high-efficiency HVAC systems. Mini-splits may not always qualify for these programs, reducing the overall savings.

How Many Square Feet Will a 36000 BTU Mini Split Cool

A 36,000 BTU mini split air conditioner can typically cool 600 to 1,000 square feet. The
exact number of square feet a unit this size can cool depends on several factors:

Room Size and Layout

  • The larger the space and the more open the layout, the more area a 36,000 BTU unit can typically cool. Smaller rooms, especially those divided into multiple spaces, are more challenging to cool and may require a higher BTU unit.

Insulation and Sealing

  • Well-insulated rooms with minimal air leaks are easier to cool than poorly insulated spaces. Add weatherstripping or caulk around windows and doors to improve insulation and increase cooling capacity.

Occupant Activity

  • The level of activity in the room impacts cooling needs. More people, electronics, and appliances generating heat will require more BTUs to cool the same square footage.

Climate Conditions

  • Ambient temperature and humidity levels affect a unit's cooling capacity. Hot or humid climates require higher BTU units compared to mild weather.

Ceiling Height

  • Rooms with high ceilings, especially those over 9 feet, need more powerful air conditioners to cool the larger volume of air. Higher BTU units, like a 42,000 or 48,000 BTU mini split, may be better suited for spaces with vaulted or cathedral ceilings.

Why Choose a 36000 BTU Mini Split Air Conditioner for Your Space

As you can see, a 36000 BTU mini split air conditioner is a viable solution for efficient
cooling and heating spaces up to 1500 square feet. With its compact design, affordable price point, and energy efficiency, a unit like this can provide temperature control for homes and businesses while reducing environmental impact. Offering both heating and cooling in one system, it provides flexibility and value across seasons. For powerful yet sustainable climate control, a 36000 BTU mini split is an option worth considering for your space. Make the investment in your comfort and lower energy bills for years to come.
