Learn More About This Unit Type

Ductless air-conditioning units, also known as mini-splits, do away with ducts to deliver comfortable air in a room. Instead, a section containing the often-noisy compressor and condenser is placed outside while a remote-controlled indoor unit is mounted on a wall.

A refrigerant line usually made of thin copper connects the two sections, making installation easy, convenient, and quick as it only requires a three-inch opening to fit. This makes it a perfect solution for places that do not have existing duct layers as well as expansions.

Furthermore, this setup is quieter and more energy efficient than traditional systems.

However, regular maintenance is necessary to keep ductless air-conditioning units running in optimal condition. Due to constant exposure to elements, including rain and extreme sunshine, the outdoor unit needs to be properly checked and cleaned at consistent intervals.

The same is also true for the refrigeration lines that connect the two major sections of the system. The indoor unit, on the other hand, needs to be tested for air quality; the thermostat must be assessed for its efficiency as well.

These scheduled check-ups will quickly identify issues and prevent costly repairs caused by neglected problems. Furthermore, a well-maintained ductless air-conditioning unit will last longer while keeping energy savings at a maximum.

Single Zone or Multi Zone

Single zone mini splits may only cool one room or section of a home. Multi zone mini splits have more than one indoor unit connected to a single outdoor unit through refrigerant lines.

Single zone units are good for single rooms and areas that don't have ductwork, while up to four units can connect to a single outdoor unit in a multi-zone system. This allows temperature control of separate areas.

BTU Ratings

All ductless systems vary in their cooling power, and BTUs indicate how many square feet per hour each unit can handle. A 6,000 BTU mini split can cool a small area of up to 250 square feet, while a 24,000 BTU unit can cool up to 1,500 square feet.

SEER Ratings

The higher this rating, the more efficient a mini-split system is. All systems today will have a rating of at least 13.

Inverter or Rotary

Mini splits come with two compressor types. Inverter compressors use just enough energy to run at the chosen temperature, while rotary compressors turn on and off. Inverter compressors are the most common type.
