Although they are extremely common outside the United States, mini splits have only recently become popular domestically. Unlike our ducted central AC's, a mini split air handler mounts on the wall or ceiling of the room, blowing air directly into the space it is cooling. We say room because they really don't have the ability to force cool or warm air through doors, partitions or other obstructions. They would require an air handler in most rooms of a home. This would have advantages in a new construction application because of energy savings due to ability to easily zone. However, many of our structures are built with central cooling and heating systems, we often see them used as add-ons to an existing system. Common examples we see of people needing more air conditioning in Tampa include: sunrooms, garages and home additions.
Daikin manufactures a premium product line with efficiency reaching up to 24.5 SEER. Within Florida, their primary competitor would be Mitsubishi with LG as a distant second. It can easily be argued that Daikin now has a much stronger distribution network with considerably more contractors. It will be interesting to see how this plays out within the mini split market or if it changes the landscape of the HVAC industry entirely.
