Ductless systems are exactly how they sound: Free of complicated ductwork (through which heat and cool air tend to escape). These split systems (also called mini-splits or duct-free systems) usually have one outdoor unit – the condenser – and at least one indoor unit – the evaporator – inside the home. They are connected with insulated refrigerant lines that pump heated or cooled refrigerant directly from the indoor units to the outdoor units and back again. And, since they use electricity for power rather than for the generation of heat, ductless systems have a high-efficiency rate – meaning a lower electricity bill to keep you comfortable.

Ductless systems are most commonly mounted on a wall and provide zoned heating and cooling for each area of the home, offering personalized comfort for every member of the family. Highly efficient, highly customizable.

If a room is too hot or too cold, Mitsubishi Electric Cooling & Heating products can handle it! Mitsubishi Electric ductless systems are specifically designed to improve the comfort level in an uncomfortably hot or cold room of an existing building. Because they don’t require ductwork, they’re the perfect heating and cooling systems for renovating older buildings that were constructed before air conditioning was available – even those with plaster walls and brick facades. The versatility and variety of applications for Mitsubishi Electric systems are virtually unlimited. They’re an excellent choice for almost any spot cooling or heating situation, including enclosed sunrooms, upstairs bedrooms, classrooms, hospitals, nursing homes, restaurants, hotels, workout rooms, computer rooms, offices, and churches.

They’re also equipped with an anti-allergen filter and prevent the cross-flow of air with contaminants. And because they can be controlled by zone, it’s easy to set the controls for the exact room temperature you want.

How does it work? Mitsubishi Electric Cooling & Heating products can fit into almost any space because their innovative engineering optimizes the capabilities of the INVERTER technology and R410A refrigerant for more efficient systems with smaller indoor and outdoor units. R410A refrigerant is environmentally friendly, with zero Ozone Depletion Potential (ODP). The units themselves are also made of recyclable materials.

Many people think that Mitsubishi Electric ductless systems must be more expensive to run than oil or gas heaters. They see the word “electric” and shy away from the anticipated price tag. Actually, the efficient technology of a ductless system can pay for itself in energy savings! And since there is no ductwork, you don’t have to worry about wasting energy through leaky ducts.

Studies show that the use of ductless electric heat pumps can save you $1,000 – $2,000 annually in energy costs versus traditional systems!

We recently got Mitsubishi Mini-Splits installed and it was an incredible experience. Our sales person was incredible thorough and knowledge, gave us a number of options, and was creative in his ideas. The day of the install Mike and Brodie showed up and we through the whole house again, were incredibly fastidious each day, and wonderfully communicative. They even came up with some ideas during the install to make it look better and ensure the units were out of the way. I would absolutely recommend them and East Coast to everyone and we've been gushing at how great the experience was!

Outstanding services and installation. We decided to change to natural gas as a means of fuel source for heating/hot water and cooking. They recommended the best boiler I have seen in 40 years on the facilities operations side. Keenan and Brody were great along with their apprentices. I highly recommend East Coast HVAC

East Coast HVAC was an excellent choice for my mini splits. Everyone on the team took time to listen to my concerns about everything from the system itself to the complexities of an install in Portsmouth’s Historic District. The install went smoothly thanks to Nate, Ian, Keelan, Kasey and Matt who were respectful of my neighbors garden and worked in a very tight space. I’d recommend East Coast to anyone needing HVAC or Electrical work. Beth

We have had a few experiences with East Coast so far, and with each experience we have been impressed with their responsiveness and professionalism from the time we call and speak with the person in the office through to when the technicians come to complete the work. This experience tops them all in that we went to turn on our AC for the season and it wasn't working. I called first thing Monday morning and they were out here and had it fixed by noon. Would highly recommend over and over again.

Both Matt (Electrician) and Trevor (HVAC Tech) were very professional and knowledgeable in evaluating the set up necessary to start the installation of a minisplit. I look forward to getting this installed by them as a professional crew and company that I can trust.
