How Does It Work?
Ductless air conditioners work similarly to your conventional central air system with a few major differences. It still transfers heat from inside your home to the outside with the use of refrigerant as well as evaporator and condenser coils. However, the big difference lies in how the cooled air gets to you. A central air conditioner has what the name implies, one centralized system that cools air and sends it through your air ducts to treat your home. This means air can get leaked at multiple points and contribute to hot spots that can be difficult to deal with.
A ductless air conditioner runs with an outdoor cabinet and up to four air handlers, also known as mini splits, that blow air directly from a fan unit inside of them. The cool air goes directly from the system into your room, there’s no play for it to leak or lose effectiveness.
The Benefits of a Ductless Home
With ductless air conditioning, you can count on a few serious benefits that will really make your home feel more comfortable. Here are just a few.
