A “split system” refers to having two pieces of equipment that work together to provide heating and cooling; an indoor unit and an outdoor unit. Like a traditional split system here in Southern California which is comprised of an inefficient gas furnace and a central air conditioner, a ductless system uses an indoor and an outdoor unit as well. The main difference is that the conditioned air is distributed into a room without the need for messy ductwork. Therefore you don’t waste money through the inefficiencies of your duct system which also tends to collect dirt, bacteria and other allergens.

It depends. Most of the Mitsubishi Electric systems provide cooling & heating however they do make a model that just provide cooling only.

A heat pump is a great option for climates like Southern California, even for colder regions such as up in the mountains.

What a heat pump does is actually extract heat from outside via the refrigerant and transfer that heat inside. It may sound odd that if its cold outside it warms you inside. It’s important to remember that not all heat pumps are created equal and frankly, many do not perform well. Fortunately, Mitsubishi Electric uses advanced technology which allows heating to take place at full capacity even with an outdoor temperature of 5 degrees Fahrenheit. By transferring energy vs. transforming it (like a gas furnace), they are very efficient and provide nice even heating without drying out the air. It’s important to know that a heat pump is an air conditioner also.

Not many brands offer this as an option but Mitsubishi Electric does. You can control one zone or all of them from anywhere at anytime without entering each room. You’ll never leave your home wondering “did I close the A/C on”?Plus, you can heat or cool your home in advance of arriving.

This is a problem that almost every house with multiple levels has to deal with. It’s called the “stack effect”. Because heat rises, there can be up to 10 degrees difference between the upper and lower floors. With a central air system you have to decide whether it’s worth freezing the downstairs just to get it relatively cool upstairs. With a ductless comfort system, every single room of your house is controlled by you at whatever temperature you want without wasting energy cooling/heating rooms that your not in.

Beware of contractors selling “zoning” for central systems. These are very difficult to design and install. They also provide a false sense of energy savings since you’re still using the full capacity of your whole house system to heat/cool certain zones.

Installation yourself is not advised and will void your warranty. Like any HVAC system, it requires professional product knowledge and skill, experience and of course the proper tools to do the job safely and correctly. Some websites promote this as a DIY project but we don’t advise that and neither do any of the major manufacturers. Ductless systems require that several specific things happen perfectly during an installation in order for the units to perform properly and last for the years they are designed for. These systems operate with pressures upwards of 500 psi and the systems need to be perfectly free of moisture and any non-condensible to avoid rust building up inside the compressor so proper installati9on is important. You must use exactly the right control wiring to avoid communication errors and the systems operate on high voltage so again proper installation is important.

Let’s start with the fact that our systems are DUCTLESS and ducts collect dirt, dust and other allergens. Ours do not. All ductless systems contain a washable filter but only Mitsubishi offers multiple stages of air filtration.

Stage 1: Nano-Platinum Filter. Ceramic and platinum nanoparticles are incorporated into the filter material to provide antibacterial and deodorizing characteristics to improve air quality.

Stage 2: Electrostatic anti-allergy enzyme filter. It reduces germs, bacteria and viruses. It helps trap dust, pollens, mites and other particles. Finally it utilizes an enzyme catalyst to help break down the sulfur atom bonds in allergen proteins, transforming them into non-allergen proteins and effectively cleaning the air.

Stage 3: Deodorizing Filter: Features a ceramic surface absorption element and uses nanotechnology for high-power odor absorption.
