The best Mini Split AC systems provide individual zone control and a host of features, from energy-saving inverter technology to quiet operation and easy maintenance. They are available with various BTU ratings to heat and cool a range of sizes of rooms, and they can be installed in homes with or without air ducts. They also come with built-in Wi-Fi connectivity and support for Amazon Alexa and Google Home voice assistants. Many models are Energy Star-rated and use environmentally friendly R410A refrigerant.
Ductless mini splits are renowned for their energy efficiency, as they eliminate the potential air loss associated with air ducts, which can account for up to 30% of an AC system’s total energy consumption. Since they are so efficient, you can enjoy a more comfortable home for less money.
These systems can also be used to make rooms more comfortable in areas that are difficult to heat or cool with traditional HVAC solutions, such as an attic or crawl space. They are also great for new construction or room additions that may not have the necessary ductwork to accommodate a central air system.
You can find a variety of options when choosing a ductless AC, from wall-mounted units that rest on the floor or ceiling to cassettes that hang from a drop ceiling. You can even get a portable version that is perfect for cooling and heating your favorite outdoor area. Some are designed to work as a standalone heater in colder climates.
The most important feature to look for in a mini split is its SEER rating, which measures its energy efficiency. You should also pay attention to the estimated yearly operating cost, which will give you a dollar amount that represents how much it costs to operate a model over an entire cooling season. These estimates are based on average operating and maintenance costs for the model you’re considering, and they can help you compare different models to find one that will suit your budget.
Another important feature to consider is the compressor type. There are 2 main types of compressors in mini splits: rotary and inverter. A rotary unit will turn on and off as it works to reach your desired temperature, while an inverter model will maintain a set temperature with a constant power output.
You’ll want to look for an air conditioner that has a high EER and SEER rating, as well as an estimated yearly operating cost that helps you compare models to find the right one for your home. You should also pay attention to the refrigerant that a model uses; R410A is being phased out in favor of more eco-friendly and more sustainable alternatives.
A programmable timer is a great feature to have, as it lets you schedule when your mini split will turn on and off so that you can save energy by setting it to run at off-peak times. Also look for a model that comes with a washable air filter to reduce allergens and dust in your home.
