Ductless FAQs
What are the main components of a ductless system?
Ductless systems are generally comprised of an outdoor portion (condenser) and indoor portion (air handler). These two components are connected by wiring and refrigerant lines to make the system function.
Will I need big holes in my house?
For each indoor air handler, there needs to be a relatively small (2.5”) wall penetration where the aforementioned refrigerant lines and wiring route from the exterior to the interior of the home. The penetration is sealed water tight, and covered by a decorative enclosure that looks similar to a gutter. Check out our Mitsubishi Case Studies page for some examples of local installations.
How many indoor air handlers can be connected to one outdoor condenser?
Anywhere from one to eight (and everything in between) indoor air handlers can be connected to a single Mitsubishi condensing unit, depending on the model used. This allows us to keep the exterior footprint minimal, while servicing multiple rooms (zones) on the interior of the home, each with their own unique set point for comfort. For homes that require several indoor units, sometimes it makes most sense from a cost or feasibility perspective to use more than one outdoor condensing unit.

Can it be used for heating as well as cooling?
Absolutely! Ductless systems have become a significant and reliable option for heating, even in our cold weather climate. We have hundreds of ductless systems around the seacoast, providing efficient primary heat to residences and commercial spaces. Watch this video about using Mitsubishi Hyper Heat for primary heating!
Are there rebates available?
YES!! Both NH and Maine customers qualify for rebate incentives, and we will help you every step of the way. Here’s a video explaining our rebate process.
Will I get a warranty?
Yes, and then some. By selecting East Coast as your installer, our Mitsubishi Elite Diamond Level accreditation qualifies your system for an extended compressor and parts warranty of 12 Years! If you choose to have another firm install your system, you may be missing out on valuable warranty time. Choose East Coast for a top-notch, certified installation, with the highest level of Mitsubishi backing. Watch this video from a recent Diamond Contractor Conference, where our President reflects on our rapid climb to the Elite Level of DC.
I heard that electric heat is inefficient…Will it cost a lot to run?
Definitely not. In fact, these systems are so efficient that the local utility companies will generally PAY you for installing them. Traditional electric heat (baseboards) is extremely inefficient since it is CREATING heat using electrical resistance. Heat pump inverter technology uses refrigerant to MOVE the heat instead of creating it. Watch this video of our President breaking down the difference!
Do I need to have the air handler mounted up on my wall?
Not necessarily. Mitsubishi offers a number of solutions, including floor-mounted, ceiling recessed, and ducted systems. Mix and match them together to create your perfect comfort control system. Watch this video about the floor-mounted indoor series!
Are they quiet?
These indoor and outdoor units are so quiet, that many times customers wonder if they are even on! See this example of an extremely quiet outdoor unit while it is operating.
