Mitsubishi Ductless Replaces Oil Heat in Ranch Home

Front of homeThis Ranch-style home located in Marblehead, MA, was built without a central AC system but did have a complete oil heating system installed. Unfortunately, due to the size of the home and the age of the oil heating system, it was incredibly expensive to run during the increasingly cold winters.

The family knew it was time for a change, so they began researching their options for heating and cooling their home. After reading some of the reviews left by previous customers from N.E.T.R. Inc., the family knew that we could design a heating and air conditioning solution for them.


The Problem: The owners of this ranch home in Marblehead, MA, wanted to remove their expensive oil heating system and replace it with a ductless heating and air conditioning solution. Additionally, they needed a new electric water heater installed.

The Solution: N.E.T.R. Inc., designed and installed a five-zone Mitsubishi ductless heating and air conditioning system that would keep the home comfortable all year long. We also installed the new electric water heater.


The Design

Example of an indoor Mitsubishi ductless AC unit installed in a home in Marblehead, MA, for heating and cooling. When this family called N.E.T.R. Inc., we knew it was going to be a big project. After touring the home and meeting the family, our team designed a five-zone Mitsubishi ductless AC system that would provide heating and cooling throughout the house.

Each of the indoor units would be installed on the walls of the rooms in locations that would provide the best airflow for the home. Additionally, an outdoor condenser would need to be installed on the side of the house to pump the treated air to the indoor units.

The Installation

Before the installation could take place, our team had to remove the existing oil heating system. This was a significant task and took some time to complete correctly. Thankfully, N.E.T.R. Inc., has 40 years of experience upgrading all kinds of heating and cooling equipment, so we were able to remove it without incident. All of the old oil heating system was disposed of properly, and work on the new HVAC system began.

Outdoor unitFive rooms required a ductless air handler to be installed. The family room and dining room had units placed to circulate the air throughout the room. Afterward, the master bedroom, home office, and sitting room were all equipped with their own Mitsubishi ductless air handlers, as well.

Each of the indoor units only requires a small hole to be drilled behind the unit to allow the refrigerant piping to run from the handler to the outdoor condenser. The condenser unit was installed on a newly poured concrete pad, which is designed to keep the unit clear of debris and snow. This Mitsubishi ductless 3.5 condenser unit offers Hyper-Heating technology.

This innovative technology keeps the condenser pumping hot air into the home even when temperatures outside reach -13 degrees Fahrenheit. Now, the family will be able to enjoy perfectly treated air even on the coldest days.

The Benefits

Because of this Mitsubishi Hyper-Heating ductless air conditioning system’s dual-purpose, the family will experience perfectly treated air all year long. Additionally, the system is much more energy-efficient and cost-effective than the old oil heating system, so they were able to receive a Marblehead rebate of $500 for upgrading the home to a more environmentally friendly option.

Each of the indoor units operates entirely independently from the others, which will allow the family to adjust the heat in each room accordingly. In fact, if they are not using one of the rooms, they can even turn off the ductless AC in the room and save money by not heating or cooling a space that is not in use.

N.E.T.R. Inc., will also provide the homeowners with a one-year warranty on labor for the entire system and a twelve-year warranty on parts for the indoor units. The outdoor condenser unit will also have a twelve-year warranty but no labor warranty.

Lastly, because of this system’s versatility, the family will be able to enjoy savings on their energy bills all year round. If the other benefits to the Mitsubishi ductless system weren’t enough to convince this family that they made the right decision, the savings will be.
