SHOWROOM
The Comfort Zone
The Monadnock Region’s first and only Mitsubishi Electric HVAC Showroom!
Electric powered heat pumps are the wave of the future. They use energy more efficiently—leading to lower monthly costs for property owners and a reduced carbon footprint as they move off of fossil fuels.
Many consumers in New Hampshire and Vermont are unfamiliar with the possibility of clean, quiet year-round comfort available to them with a Mitsubishi Electric ductless HVAC system. That’s why we created The Comfort Zone— a showroom where you can experience different solutions firsthand and speak with one of our licensed professionals.
The Comfort Zone is located at 216 Marlboro Street in Keene. Stop by, we look forward to welcoming you every weekday from 7 AM to 4 PM.

The Mitsubishi Electric ductless HVAC systems available at The Comfort Zone includes:
Wall Mount Unit
Multi-Zone Outdoor Unit
Ducted Unit
Ceiling Cassette
Floor Mount Unit
Recessed Ceiling Cassette
Moreover, we offer 15 different models, depending on your property’s needs and budget. Don’t worry—we’re here to support you!
The federal government aims to install 12 million heat pumps in the United States over the next ten years. Federal tax incentives are currently available for home and business owners who install a qualifying system. Local utility rebates are available in some areas, and Bergeron Mechanical Systems offers a 0% financing option for qualifying buyers.
The value is there to be taken—from the upfront tax advantages and financing to the prospect of lower monthly costs. But we also know that people need to feel comfortable when they make a change. That’s why we started The Comfort Zone—we want our customers to get a firsthand experience of what their ductless solution will be like before they buy. Experience, then buy.
The Challenge and the Solution
Old-school, conventional HVAC system runs on a simple formula—go full power until it reaches the temperature requested by the thermostat, turning off and on to maintain that temperature. Most of us have had the experience of a frigid winter day and hearing the heat start up and then stop again repeatedly. Each time those systems turn on that noisy outdoor unit, it uses more energy than it does during regular operation.
Ductless systems can’t make our winters any milder, but they can ensure that hot air (or cold air on a summer day) is delivered much more efficiently. That starts with the INVERTER.
Think of the INVERTER like your own heart—which is appropriate because the INVERTER really is the heart of the ductless HVAC unit.
Your own heart gradually increases its rate to meet your body’s needs of the moment (easing into the day after waking up, exercising, etc.) It doesn’t dramatically shut down and crank back up. A healthy heart regulates, adjusting to your needs at a particular moment.
So too, does the INVERTER. It automatically adjusts conditioning when its temperature sensors detect even subtle changes. You don’t have to think about it, and the system is so quiet you won’t hear it.
Rooms are cooled and heated faster and more efficiently. The INVERTER regulates energy consumption so that the system only uses the precise amount of energy needed to keep each room at the temperature you choose. This process is greener and more sustainable than running at full power, like conventional systems, and can reduce energy consumption.
How Ductless Systems Work
A ductless system allows you to target heating and cooling to the rooms and spaces where it’s needed most. A conventional HVAC system always heats or cools the entire home or building.
Imagine if every time you turned on one water faucet in your house, all of the faucets turned on. No one would ever choose a plumbing system like that, but conventional HVAC systems heat and cool in this way.
Most homes have rooms that are used more than others. The living room, where people gather, and the home office are the rooms you may want to keep at maximum comfort. A ductless system allows you to target these rooms.
The essential components of a zoned air conditioning and heating system are the outdoor unit, the indoor unit, and the wise comfort controls. The system operates by transferring heat to and from an outdoor unit to one or more indoor units. The units are connected by refrigerant pipes, a substance that absorbs heat.
Ductless systems come in two different types:
- Single-Zone System: Ideal if you only need cooling and heating in a single space.
- Multi-Zone Systems: Designed for cooling and heating multiple spaces.
Within these two options is an array of cutting-edge technologies, which may or may not be included with different models. The trained professionals at The Comfort Zone will be sure to walk through all of this with you.

The Technology
Mitsubishi Electric products include a variety of technologies, including:
H2i plus™ takes hyper-heating technology to a new level, providing 100% heating capacity down to -5°F outdoor ambient (without wind chill) temperature. It’s ideal for climates like ours.
3D i-see Sensor® increases the sensitivity of the system to your comfort needs and gives you opportunities to further customize comfort in your home or business. The sensor scans each room to produce a complete thermal profile that includes heat signatures based on size, temperature, and movement. With this capability, the 3D i-see Sensor can detect and eliminate cold or hot spots and can determine whether a room is occupied.
Econo Cool adjusts the amount of air directed toward occupants based on the air-outlet temperature.
Nano-platinum Filter incorporates nanometer-sized platinum ceramic particles that kill bacteria and deodorize the air.
Electro-static Anti-Allergy Enzyme Filters attract and capture dust particles, molds, and bacteria and break them down with enzymes.
Swing Mode moves air throughout the room like an oscillating fan.
Powerful Mode temporarily drops or raises the set temperature for 15 minutes so that automatic fan speed adjustments made possible by the INVERTER will more quickly bring your room to your desired temperature.
Direct Airflow sends airflow directly toward the occupant.
Indirect Airflow is useful when the occupant does not wish to have air blowing directly on them.
Absence Detection activates when no one is in the room. The 3D i-see Sensor can direct your indoor units into energy-saving mode.
Advanced Occupant Detection: Select ceiling-recessed indoor unit models are equipped with sensors that rotate a full 360º in three-minute intervals. This allows the units to detect human body temperature and use an algorithm to calculate the number of people in the room and their positions.
Our indoor units do more than keep each room in your home at the perfect temperature; they also continuously clean the air.
