Ductless Mini-Splits 101
We’ve partnered with Mitsubishi to offer the industry’s most comprehensive ductless mini-split product lineup. Read on to learn more about this increasingly popular HVAC option.
Mini-Splits Keep You Comfortable Year-Round
A mini-split heat pump or ductless heat pump operates the same way that a traditional split-system heat pump does. During warm weather, the heat pump removes heat from the home and sends it outside. When it’s cold out, the heat pump reverses operation, extracting heat from the air outside and transferring it into your home. Your local American Standard dealer can tell you more about Mitsubishi mini-split systems.
Advantages of a Ductless System
More and more homeowners in the US are discovering the benefits of ductless systems. Yes, you can cool and heat a space (or zones throughout your whole house) without installing ductwork, but the advantages don’t stop there. They’re highly efficient and quiet, use variable speed technology for excellent humidity control, and offer personalized comfort. All-electric HVAC systems are an ideal way to ensure sustainable comfort too.
Options for Every Space and Style
A mini-split air conditioner or mini-split AC and heat system makes sense in any space you want to heat and cool or simply cool, but where there isn’t existing ductwork—and multi-zone ductless systems allow you to control several rooms at the same time. Some of the most common uses include attached and detached garages, room additions, sunrooms, backyard sheds, attics, and historic homes.
Simple and Efficient Operation
Mitsubishi Electric’s ductless systems pair an outdoor electric heat pump with one or more indoor air handlers/mini-split units, and can be controlled via a wall unit, remote control, smartphone app, or voice assistant. The units are connected by refrigerant lines to transfer the desired heating or cooling to your custom comfort zones—keeping your home warm and toasty in the winter and cool and dry in the warmer months.
Understanding the Details of Mini-Split Systems
Ductless mini-split systems heat and cool your home just like other HVAC systems, but the installation and operation have some subtle differences. Here are a few of the most common questions people ask.
Here’s Why We Recommend Mitsubishi Mini-Split Systems
American Standard recommends mini-split systems from Mitsubishi Electric Cooling & Heating for several reasons. Mitsubishi Electric mini-split systems are routinely ranked as one of the best mini-split brands worldwide, offering superior energy efficiency and cost-effective heating and air conditioning solutions in any type of climate.
In 1959, Mitsubishi pioneered ductless mini-split heating and cooling in Japan, and ductless systems have since become the standard in the Asia-Pacific region and have gained popularity in Europe.
Add it all up, and you can understand why American Standard has partnered with Mitsubishi to bring this technology to residential customers in the US. With these highly energy-efficient systems, you may be able to reduce your energy consumption by up to 40% compared to conventional systems.
As with all HVAC equipment, optimized performance from your new mini-split system depends on a quality installation. Contact your local American Standard dealer to get started enjoying the benefits of today’s leading ductless HVAC technology.
