Ductless air conditioning, or mini-split systems, has transformed how we cool our homes in the summer. In this article, we'll dive into the internal components of ductless air conditioning and look at how these modern and efficient systems provide superior comfort and flexibility in British Columbian homes. At Moore and Russell Heating and Air Conditioning, we've got you covered if you're thinking about upgrading your cooling setup or simply curious about the technology behind these units.

Therefore, if you want to know how ductless air conditioning works, keep reading!

What are the disadvantages of ductless AC systems?

Although ductless air conditioners have many benefits, they also have a few drawbacks to consider when choosing the best cooling solution for your home. Here are some of the potential disadvantages of ductless AC systems:

  • Higher Initial Cost: When compared to conventional central air conditioners or window units, ductless air conditioning units can be more costly to install. The initial cost involves the cost of indoor and outdoor units, as well as professional installation.
  • Limited Zoning: Although ductless systems provide individually regulated temperatures in different zones, the number of indoor units can be restricted by the capacity of the outdoor unit. This may limit the number of areas or rooms that can be independently cooled unless you want to install a ductless unit in each room of your home.
  • Maintenance and Repairs: To ensure adequate performance, ductless systems need regular maintenance, including cleaning filters and coils. If an issue develops, repairs may be more complicated and possibly more expensive than fixing conventional central air conditioning units, as you will need to service several units rather than one.

Despite these drawbacks, ductless air conditioning systems are still an excellent option for many situations due to their flexibility, energy efficiency, and capacity to deliver zoned cooling. When thinking about a ductless system, it's critical to weigh the disadvantages against the advantages. Furthermore, by working with a local HVAC company, you can be confident that you're installing the right cooling system for your home and needs.

How does a ductless AC unit work?

A ductless air conditioning unit, also commonly known as a mini-split system, works on similar basic principles as a conventional central air conditioner but with a few important design and functionality differences. Here's how a ductless air conditioner works:

  1. A ductless AC system's indoor unit is mounted on a wall or ceiling within the room you want to be cooled. It is made up of an evaporator coil and a fan. When you turn on the cooling system, the fan draws warm interior air over the cold coil.
  2. To promote the process of cooling, the refrigerant, a special cooling substance, moves through the compartment. As it passes through the evaporator coil, the refrigerant soaks up heat from the air inside and converts it to cool air.
  3. The compressor and condenser coil parts are located in the outdoor unit. The compressor compresses the coolant and transports it to the condenser coil, where the heat that is absorbed is released into the surrounding air outdoors.
  4. The refrigerant circulates between the units in the house and outdoors on an ongoing basis, taking in heat from the inside air and distributing it outside. This procedure is repeated until the desired indoor temperature is met.

Ductless AC units usually come with an optional remote or a wall-mounted thermostat that enables you to easily adjust the temperature and settings. Furthermore, unlike conventional central air conditioning systems, ductless units don't depend on a duct network to distribute cool air. They instead deliver air conditioning immediately to the room, lowering the energy losses related to ductwork. Pretty cool, hey?

What are the advantages of a ductless mini-split?

Ductless mini-split systems provide numerous benefits, making them an attractive and effective cooling solution for a variety of uses. The following are some of the primary benefits of ductless mini-split systems:

  • Energy efficiency: Reduces energy waste in the absence of ducts, which can save you money on your monthly utility costs.
  • Zoned cooling: Zoned cooling allows you to set different temperatures for each room for more personalized comfort.
  • Simple installation: Installing these units is relatively quick and easy compared to standard cooling systems.
  • Placement flexibility: Indoor units have a variety of mounting possibilities that enable you to customize the look of your room for aesthetic purposes and optimal cooling capacity.
  • Quiet operation: Ductless air conditioners operate quietly to maintain a peaceful environment.
  • There is no need for ductwork: Ideal for homes with no existing ducting.
  • Environmentally friendly: Uses cutting-edge, environmentally friendly refrigeration fluids that lower your environmental impact.
  • Compact: Outdoor units are compact and save space.

Ductless mini-split systems are flexible and efficient, with excellent control and ease of use. They are a great option for residential spaces, providing homeowners with many advantages. However, it is critical to select the proper system size and seek the help of a professional who can make sure that the installation is conducted correctly and safely to ensure optimal performance and longevity of the equipment.

How many square feet can a ductless mini-split cool?

A ductless mini-split system's cooling capability differs depending on the model and its BTU (British Thermal Units) rating. That said, the cooling capacity of ductless mini-split systems typically ranges from approximately 6,000 BTU to 48,000 BTU or more.

Furthermore, a variety of factors can impact the actual cooling capacity required for any given space throughout your home. For example, the insulation quality in your home, ceiling height, window quantity, sunlight exposure, and the number of occupants can all have an impact on the cooling load.

As such, it's best to consult with a professional HVAC technician for a more precise estimate of the cooling capacity required for your specific space. They can conduct a heat load calculation to determine the optimal size and performance of the ductless mini-split system for your cooling requirements, ensuring reliable and efficient cooling throughout your home.
