Mini-split systems are smaller version of larger split air conditioning systems where there is an outdoor condenser and an indoor evaporator/blower assembly. The primary difference is that mini-splits do not require ducts to be installed throughout the home or business. Typically mounted on an outside wall, installation in an existing building is faster and more economical than that of conventional AC systems.
Although you can purchase AC only mini-splits, most customers prefer to install the hybrid inverter heat-pump versions. These systems provide both heating and cooling and are considered one of the most efficient ways of providing climate comfort to your home or business. Once very popular in Southern areas, heat-pumps are quickly gaining popularity in the Northeast because of their advancing efficiency. In fact, some new homes in our area are being built with only mini-splits as the heat and cooling source.
AC systems work by removing heat and humidity from the indoors and transferring it outside. A heat pump takes heat from the outdoors and transfers it to the indoor space. Even in temperatures as low as -22F, some heat pumps can operate effectively as there is still some heat in the environment! One of the reasons these systems are so efficient is that they do not have to "make" heat, they operate by transferring heat that already exists. Here is a link to an excellent article about mini-splits by one of the manufacturers we work with: https://www.fujitsugeneral.com/us/residential/what-is-a-mini-split.html
The indoor units hanging bracket is installed on a wall and then a hole (less than 3 inches diameter) is drilled to the outside. Refrigerant, drain line and control wire are run through the hole and connected to the indoor unit. The unit is secured to the bracket and the inside work is complete. The unit covers the hole, pipes and wire so you get a clean finished look.
The outdoor unit is mounted on a stand or wall bracket and connected to the pipes and wire from inside. A molding is installed on the wall to conceal the pipes also providing a clean finished look.
How much power do they require?
Smaller size units are powered by a 15 amp 240 volt circuit , medium is 20 amps at 240 volts. Some of the larger units require 30 amps, and some multi-head systems need 40 or 50 amps.
Do I Need and Electrician?
If you have your own electrician, we will be glad to provide them with the units specifications so that the wiring can be done before our arrival. That will allow us to provide start-up on the day it is installed. If you do not have your own electrician, in many cases our electrician can preform the installation for you.
Do you service these systems?
Yes we do. We can provide regular cleaning of both the indoor and outdoor units as recommended by the manufacturer. And although they are extremely reliable, we also provide repair service in the event that it becomes necessary.
Are they loud?
Not at all, in fact most people are surprised as to how quiet both the indoor and outdoor units are. Gone are the humming, rattling and blowing of old window units!
