Two-Family Home Get Supplemental Heating

Two-family home in Boston, MA, gets supplemental heating and cooling with Mitsubishi ductless.

Like many older homes in and around Boston, this two-family home was built without central air conditioning. The house had a forced hot water radiator system for heating in the winter. Without an air conditioning system, the family relied on window AC units in the living room and simply opened windows throughout the rest of the home to keep the rooms bearable.

Eventually, the intense summer heat got the better of the owners, and they knew it was time to find a solution for their home. One of the difficulties with heating and cooling this home was the 9 ½ foot ceilings in the living room. The owners knew that they would need to find an energy-efficient solution that would make it easier to keep their home at a comfortable temperature without costing a fortune because of the tall ceilings.


The Problem: Two-family home in Boston with 9 ½ foot ceilings needed a heating and air conditioning solution that was energy-efficient and cost-effective.

The Solution: N.E.T.R., Inc., installed a single-zone Mitsubishi ductless air conditioning system with a heat pump for year-round comfort.


The Design

Because of the size of the rooms that needed to be heated and air conditioned, the N.E.T.R., Inc., team determined that a single unit in the dining room would be the solution this family needed. The indoor AC unit would be mounted on the wall in the dining room, where it would be able to provide the best airflow throughout the home. Additionally, a single outdoor unit would be installed outside the house where it was out of sight and easy to access for future maintenance or repairs.

The Installation

Installing the system for this home was simple. Ductless units do not require ductwork in order to provide treated air throughout the house, so the family was able to avoid extensive renovations to accommodate new air ducts. Instead, the indoor air handler was mounted above the door in the dining room.

The technician drilled a small hole in the wall and then ran tubing through the walls like electrical wiring to the outdoor condenser unit and heat pump. This simple setup allows the treated air to be transferred from the outdoor heat pump to the air handler efficiently and quickly.

Before the outdoor condenser unit could be installed, N.E.T.R., Inc., poured a concrete pad where the condenser would be placed. We then installed the Mitsubishi ductless heat pump on top of the pad to keep it free from debris and potential blockage from snowdrifts.

The Benefits

The family will now be able to enjoy their living room and dining room all year long with the Mitsubishi ductless system we installed. These Mitsubishi ductless ACs provide high-quality, energy-efficient cooling for a fraction of the cost it takes to run window ACs during the summer. Additionally, the Mitsubishi ductless system doubles as a high-efficiency heating system.

Because of the way the Mitsubishi system operates, it only takes about the same energy as a lightbulb to operate. Now, the family will save tons on their air conditioning costs throughout the warmer months because they will not have to rely on window ACs.

Another benefit of the Mitsubishi ductless system is that it provides supplemental heating in the winter. If the family finds themselves a little chilly on a cold night, the new ductless system can help bring the living room up to a more comfortable temperature with the press of a button.

Lastly, the Mitsubishi ductless AC system is easy to expand upon in the future. So, if the owners decide that they’d like to add an additional unit in the bedroom or kitchen, all they have to do is give N.E.T.R., Inc., a call.
