What Is Mini Split AC?

Mini Split AC is a ductless system that’s popular among homeowners because it’s super energy-efficient, environmentally friendly and customizable. It’s also the perfect solution for a new home or remodeling individual rooms.

The components of a mini-split system are similar to those of a central system, though the indoor units are typically wall-mounted. Each of these units is equipped with an evaporator coil, an air handler, and a blower.

Most of the indoor units are hung on walls with included brackets, although some models Mini Split AC may be installed on the ceiling. The outdoor unit, which is a compressor/condenser that provides power to the indoor units, is located outside the house. The conduit that connects the outdoor unit to the indoor units houses refrigerant lines, drain pipes and a condensate drain.

It’s important to have a licensed HVAC contractor install your mini split system because a mistake can lead to an electric fire, a faulty system or even the loss of your ductwork. If you’re considering a mini split for your home, contact a local Carrier dealer to get help from a trained HVAC professional who can ensure the best possible installation and service.

Ductless systems have an advantage over window and portable AC units because they can be hidden out of sight, which makes them less noticeable and easier to integrate into your home’s style. They also don’t require the expensive installation of ducts, which can save you money in the long run.

They’re also the industry standard for quiet operation, with average operating sound levels as low as 19 dB (which is nearly silent). In addition to a lower noise level than other types of air conditioning, they’re much more efficient and can help you save on utility bills.

You can choose from single-zone or multi-zone models of these ductless systems, and you can control each zone individually with a remote thermostat. This allows you to condition specific areas of your home, like the master suite or a family room connected to the kitchen, when those zones are in use.

Another big advantage is that you can cool only the rooms in your home where you need it, and switch off heads in rooms that aren’t occupied. This lowers your energy bill by only operating the heads in rooms that you’re using, and it helps keep humidity from accumulating.

One disadvantage of a ductless system is that it’s generally more expensive to purchase and install than a traditional central AC system. This isn’t just because of the cost of installing a ductless system, but also because it involves more complex electrical work.

Most high-efficiency mini-split units require 208-230 volt service, which requires an electrician to perform the proper wiring. This isn’t an issue for most homes, but if you have older wiring or your home doesn’t have a panel that can provide that voltage, it could be a problem.

You’ll need to ask your HVAC company if you can purchase a 230-volt system, or if your home’s current wiring can provide the voltage. Taking a few minutes to check this can save you time and trouble in the future.
