Why Choose an MRCOOL or Buck Cool 18000 BTU Mini Split?

As an energy-efficient heating and cooling solution, an 18000 BTU mini split is an excellent choice for many homeowners. Here are a few of the main benefits of selecting an MRCOOL or Buck Cool 18000 BTU mini split:

Efficient Climate Control for Versatile Spaces

  • An 18000 BTU mini split provides powerful heating and cooling for spaces up to 1000 square feet, making it ideal for additions, bonus rooms, attics or anywhere a traditional HVAC system is not practical. With an efficiency rating of 23 SEER, an 18000 BTU mini split can significantly lower energy costs compared to a standard unit.

Quiet Operation

  • An 18000 BTU mini split operates at a low decibel level, producing little noise pollution for you and your neighbors. The quiet performance is perfect for residential or commercial spaces.

Flexible Installation

  • An 18000 BTU mini split only requires a small wall opening for the refrigerant lines, allowing for installation in places where installing ductwork is nearly impossible. The condenser unit sits outside, keeping the inside space clutter-free.

Precise Comfort Control

  • An 18000 BTU mini split gives you full control over the temperature in the room with options like fan speed adjustment, louver directional control, 24-hour timers, and sleep mode. You can customize the settings for maximum comfort.

Low Maintenance

  • An 18000 BTU mini split is designed to operate for many years with minimal service needed. The self-cleaning indoor unit prevents the buildup of mold, mildew, and pollutants. The air filters only require occasional replacement, typically once a year or less.

How Many Square Feet Does an 18000 Mini Split Cover?

An 18,000 BTU mini split air conditioner can typically cool 600 to 800 square feet of space. The exact amount depends on several factors:

Insulation and construction of your building

  • Well-insulated spaces with few windows require fewer BTUs to cool. Homes with lots of windows or made of materials that transfer heat easily, like metal, may need additional BTUs.

Number of stories in your building

  • An 18,000 BTU unit will cool more square footage on one floor versus multiple floors since heat rises. For multi-story spaces, you may need a larger unit or multiple smaller units.

Number of people occupying the space

  • More people means more body heat and CO2 being generated, requiring greater cooling power.

Heat sources in the space like electronics, lighting, and appliances.

  • Spaces with many heat-generating devices need increased BTUs to counter the additional warmth.

Local climate and temperatures

  • Colder regions need more BTUs to cool spaces versus warmer areas with lower temperature differentials.

Desired indoor temperature

  • The lower the temperature you want to maintain, the higher the BTU requirement.

A DIY Installation Guide for Your 18000 BTU Mini Split

Prepare the Installation Area

  • To install an 18,000 BTU mini split, you will first need to prepare the installation area. Ensure you have selected a location with sturdy wall space and access to power. The area should be free of obstructions and at least 7 feet from the floor for the wall unit.

Install the Wall Mount

  • Next, you will install the wall mount that will hold your mini split. First, locate wall studs using a stud finder. Then, mark the stud locations on the wall. Hold the wall mount up to the desired position on the wall and mark the mounting hole locations.
  • Drill pilot holes into at least two wall studs. Secure the wall mount to the studs using lag bolts. Ensure the mount is level before tightening the lag bolts completely.

Install the Refrigerant Lines

  • With the wall mount installed, you can now run the refrigerant lines from the outdoor condenser unit to the wall mount. Measure the necessary line length, allowing extra for turns. Cut the lines to size.
  • Connect the refrigerant lines to the wall mount and outdoor unit according to the instructions. Braze all connections to prevent leaks. Wrap all joints with pipe insulation to maximize efficiency. Secure lines to the wall to prevent sagging.

Connect the Condensate Drain Line

  • Your mini-split will produce condensate as it operates which must be properly drained. Locate the drain outlet on the wall mount and the outdoor unit. Run a condensate drain line between the two outlets, securing it in place. Pour water into the wall mount outlet to ensure proper drainage before operation.

Connect Electrical Wiring and Power

  • The final step is connecting the electrical wiring and powering your mini-split. Shut off power at the circuit breaker. Run wiring from your electrical panel to the wall mount and outdoor unit. Connect the wires according to the wiring diagram in the instructions.
  • Turn the circuit breaker back on and power on your mini-split using the included remote control. Test all functions to ensure proper operation before leaving the unit unattended. Your DIY mini-split installation is now complete!

Where to Buy 18000 BTU Mini Split AC

When searching for a 18000 BTU Mini Split, it's important to consult trustworthy resources to discover the ideal option that matches your needs. Nevertheless, the leading selection is:

  • The Trade Table is a Premier Home Store for HVAC products. Consider checking out our store for 18000 BTU Mini Split below. If you want to explore more options, feel free to check out our wide range collection of Mini Split Systems.

How Many Square Feet Will an 18,000 BTU Mini Split Cool?

  • An 18,000 BTU mini split should be able to cool around 650 to 900 square feet, depending on factors like insulation, windows, and climate. As a general rule of thumb, you'll need around 20 BTU of cooling power for every square foot of living space. However, every home is different, so the actual capacity can vary.

  • The most accurate way to determine if an 18,000 BTU unit is right for your space is to have an HVAC contractor evaluate your home. They can measure the square footage of each room, check for air leaks or insulation issues, and ensure the mini split you choose will properly cool your whole home.

What Size Room Will an 18,000 BTU Mini Split Cool?

  • An 18,000 BTU mini split is typically good for medium to large rooms in a home, such as:

    • Living rooms (300-500 square feet)

    • Open concept kitchens and living rooms (500-800 square feet)

    • Basements (500-900 square feet)

    • Master bedrooms (300-500 square feet)

  • For the best results, place the air handler for the mini split in the center of the space you want to cool. The cooled air will disperse efficiently to surrounding rooms. You may need additional mini-split units for isolated rooms far away from the main unit.

Is 18,000 BTU Enough for a House?

  • An 18,000 BTU mini split may be enough to cool some smaller homes, around 650 to 1,200 square feet. However, for the majority of houses, especially larger ones, 18,000 BTU will not provide enough cooling power on its own. In these cases, it's best to use a multi-split system with several air handlers and an outdoor compressor that can produce 36,000 BTU or more.

  • A multi-split system allows you to place air handlers in different areas of the home for balanced, whole-house cooling. An HVAC pro can determine the right system and BTU size for your specific home based on an evaluation of the square footage, layout, and other factors.
