Floor Mount Air Handlers

Voomi Supply carries floor mount mini split air handlers from brands such as Daikin, Mitsubishi Electric, Gree and Haier, in floor console and floor-ceiling types across single zone and multi zone systems from 9,000 to 36,000 BTU. A floor mount air handler is the indoor unit of a ductless mini split, installed low on a wall or hung from the ceiling, and it connects by refrigerant lines to an outdoor unit. Every order ships with Voomi's 30-day return policy and free help matching a indoor unit to your outdoor system.

Choosing a Unit

Check

Why it matters

Capacity in BTU

Match the room load; units on this page run from 9,000 to 36,000 BTU

Refrigerant

Listings show R-454B and R32, and the outdoor unit must use the same refrigerant

Zones

Single zone units pair with one outdoor unit; multi zone units need a compatible multi zone outdoor unit

Heat pump or cooling only

Filters on the page separate cooling-only from heating and cooling models

Voltage

Most units are 208/230V; confirm before ordering

Sizing a Floor Mount Unit by Room

These ranges are a starting point from a mini split sizing guide. A Manual J load calculation is more precise, especially for multi zone layouts, unusual ceilings or windows, or sizes near the edge of a band.

Room size

Approximate capacity (BTU per hour)

Up to about 350 sq ft

6,000 to 9,000

About 350 to 500 sq ft

9,000 to 12,000

About 500 to 750 sq ft

12,000 to 18,000

About 750 to 1,000 sq ft

18,000 to 21,000 or more

 

Condition

Sizing adjustment

Hot or humid climate

Use the high end of the band or the next size up

Vaulted or tall ceilings

Move up a size for the extra air volume

Large south or west facing glass

Move up for afternoon solar gain

Poor insulation or a leaky room

Move up; tight, well insulated rooms can use the low end

Kitchens, sunrooms and crowded rooms

Add capacity for the extra heat load

Single Zone vs Multi Zone

Setup

How it works

Check

Single zone

One indoor unit connected to one outdoor unit by a refrigerant line set

Indoor and outdoor model must be a listed match

Multi zone

Several indoor units, such as a floor console and a wall unit, share one multi zone outdoor unit

Each indoor unit must be on the outdoor unit compatibility list and the total capacity must fit

The page filters list single zone and multi zone options, so use the Zones filter if you know the outdoor unit.

Installation Checklist

Item

What to check

Mounting height

One manufacturer guide says to mount a floor unit at least 6 inches above the floor, so follow the installation manual for your model

Clear space

Keep furniture and appliances away from the intake and discharge

Sunlight and airflow

Avoid direct sunlight, which can affect temperature readings, and aim the airflow away from seating and sleeping areas

Wall strength

Check the wall first; thin or non load bearing walls may need reinforcement

Line set and drain

Plan the refrigerant line set and condensate route to the outdoor unit; use a condensate pump if gravity drainage is not possible

Electrical

Confirm the voltage on the data plate, usually 208/230V, and the circuit the manufacturer requires

Refrigerant

Match the indoor unit to an outdoor unit that uses the same refrigerant, such as R-454B or R32

Parts of a Ductless Floor Mount System

Part

Role

Indoor floor mount air handler

Delivers conditioned air to the room, with a filter and a fan

Outdoor unit

Houses the compressor and condenser coil

Line set

Copper refrigerant lines between the two units

Condensate drain or pump

Carries away the water the indoor coil removes from the air

Remote control

Sets temperature, mode and fan speed

Air filter

Washable or replaceable filter; the low position can collect dust faster, so check it often

Accessories and Related Collections

Most installs also need line sets and a condensate pump if gravity drainage is not possible. Other indoor unit styles are in ceiling cassette units and concealed duct units.

Frequently Asked Questions

While floor-mounted air handlers offer several benefits, they also have some disadvantages:

  • Higher Initial Cost: The upfront cost of floor-mounted units can be higher compared to wall-mounted units, particularly as not all brands and models have a floor-mounted variant. 
  • Space Requirements: Floor-mounted units require floor space and need a significantly large area set aside for the cooling system. 
  • Maintenance Needs: Due to their proximity to the floor, these units can accumulate dirt and dust more quickly, necessitating more frequent cleaning and maintenance. 

The choice between floor-mounted and wall-mounted units depends on your specific needs and space considerations:

  • Air Distribution: Floor-mounted units often provide more even air distribution in rooms with high ceilings, as they blow air upwards towards the ceiling, which then circulates throughout the room. 
  • Aesthetics: Wall-mounted units are more discreet and take up less floor space, making them suitable for rooms where wall space is available and aesthetics are a priority.
  • Installation Flexibility: Floor-mounted units can be installed in spaces where wall mounting is not feasible, such as rooms with limited wall space or where wall mounting is not desired.

Yes. A floor mount air handler is the indoor unit of a ductless mini split, so no window is needed. Refrigerant and condensate lines pass through a small wall opening to the outdoor unit, which sits on the ground or on a wall bracket.

Yes, when it is paired with a heat pump outdoor unit. Cooling-only models also exist, so check the operating mode in the product details before ordering.

Often yes within the same brand and refrigerant, but compatibility depends on the model series. Check the manufacturer matchup for the indoor and outdoor model before ordering.

A room of about 350 to 500 sq ft usually needs 9,000 to 12,000 BTU, and about 500 to 750 sq ft usually needs 12,000 to 18,000 BTU. Hot climates, tall ceilings and sunny rooms call for more, and a Manual J calculation gives the exact number.

A floor console sits low on the wall, while a floor-ceiling unit can stand low on a wall or hang under the ceiling, depending on the model. Check the product details for the mounting positions the manufacturer approves.

Pick a spot with clear space around the unit, away from direct sunlight, with the airflow aimed away from seating and sleeping areas. Check that the wall can carry the unit and that the line set and drain can reach the outside.

Yes. Listings on this page show R-454B and R32 units, and an indoor unit must be paired with an outdoor unit designed for the same refrigerant and listed as a match by the manufacturer.

Yes, professional installation is recommended for floor-mounted air handlers, as the process involves connecting refrigerant lines, electrical wiring, and ensuring the correct placement of the unit for optimal airflow. Improper installation can lead to reduced performance and potential system failure. A licensed HVAC technician ensures the system is installed correctly and complies with local codes.
