One of our favorite things to do is give a homeowner back their views of the outside world after years of putting up with window air conditioners. In the case of this Lexington split-level colonial, we were able to remove six window ACs and give the homeowners the ability to enjoy the windows all year long!

Problem: Six unsightly, inefficient, and noisy window units were blocking the windows and detracting from the home's overall aesthetic while racking up huge electric bills.

Solution: A five zone Mitsubishi ductless split system powered by one outdoor condenser and five wall-mounted heads was installed.

Woburn, MA is near Horn Pond, which is the head waters of the Mystic River. As a result, many families, like the one in this split-entry home, live near wet areas and are concerned about humidity and air quality. Our family was using window air conditioners to try to keep the temperature and humidity under control in the summer, but the window units just weren't cutting it. They started to look for a better solution for both their living room, where the family spent most of their time.

In addition, they have a lovely sunroom that was hard to keep adequately warm in cold weather. Even with gas heat and baseboards throughout the home, this area still ended up cooler than they liked. Finding a solution that would allow them to address both heating and cooling needs was really important!

Better Air Quality is Important, Especially in Areas Like Woburn

One of the best parts of ductless systems is their flexibility. There are wall-mount units available, and also floor-mounted ductless units like the one we used in this home, pictured below. It looks mostly like a normal radiator type unit, but this system can deliver heating and cooling with pinpoint control any day of the year.

For our family, we could deliver the comfort they needed -- cooling in the living room, and heating in the sunroom/family room all with the same system. In fact, they could have one room cooled while the other is warmed. The temperature is controlled independently, allowing each room to be the perfect temperature!

Moreover, the system we installed will help them maintain a better quality of air and filtration of the air in the home, which is important especially if anyone in the home suffers from seasonal allergies or have other sensitivities to air quality.

Over time, our needs change. For our empty-nest homeowners in Burlington, heating and cooling the whole house seemed wasteful AND expensive. Split level homes like this one can also be especially challenging to heat and cool, so creating solutions that allow more customization of temperatures in certain rooms is a blessing. They were looking for a solution that allowed them to have the comfort they yearned for, without having to heat or cool the whole home, and spending money they'd rather use on more enjoyable things.

Arlington is adjacent to Cambridge and Charlestown and features many charming cape style homes like this one. Many of these homes were built without central air conditioning, and homeowners have been forced to rely on window units for years. However, window AC units are inefficient, which makes them very expensive to run, and they are noisy as well. I once even heard my mother say, "Close the door! Don't let that expensive cold air out!" Now, there are better options for greater comfort with less noise and that cost much less to run.

Our homeowners in Arlington were tired of the seasonal install required for window air conditioners, followed by the need to remove and store them every winter. It always seems you've put the units away just before the last surprise heat wave hits! It was time to take care of that problem once and for all. The owners wanted to replace the ugly window AC units that were an eye-sore on the otherwise picture-perfect exterior. In addition, they wanted to get a little better heating and cooling for this home.

Problem: Window units are inefficient, noisy, and expensive to run. This home had rooms that were hot and sticky in the summer and they were looking for a better, more cost-effective solution.

Solution: NETR installed a single zone ductless system to provide excellent cooling and allow for an efficient heating boost during the winter. This Cape home will now be comfortable on hottest and coldest days of the year.

The ideal air conditioning solution for a picture-perfect Cape

Our homeowners contacted NETR because they knew we specialized in working with Mitsubishi ductless systems which are known for their reliability, quality, and energy efficiency.

NETR installed an outdoor heat pump condenser and one indoor wall-mounted AC unit to bring comfort to the first floor. In the future, if the family decides to add additional indoor units, the ductless heat pumps systems are designed to allows for expansion at a later date.

The outdoor unit, on the left, is small and unobtrusive and the piping blends into the home's exterior wall. The indoor units are easily mounted out of the way and deliver custom comfort right where you need it most in addition to distributing the cool air more efficiently than the window ACs.

This family was eligible for two separate rebates- a Mass CEC rebate of $620 and a Mass Save rebate of $500, totaling $1,120, making this home improvement affordable in addition to the energy savings it will deliver every day of the year!

One of the most common problems homeowners face is temperature varying throughout the home.  In the winter, the family room might be toasty, but the bedrooms are frigid, or there simply isn't adequate cooling in spring and summer.  Often, as the humidity begins to climb, these problems get worse. When it never seems to be comfortable in the house, it can be amazing how debates over thermostat can cause family strife.

This home on Tewksbury, MA faced some of these problems. Our empty-nest homeowners were sick and tired of the dramatic and uncomfortable temperature fluctuations in their home.  They have an oil-fired, forced hot water heating system using radiators in the home, but this does not effectively circulate heat.

The homeowners also did not have central air system and needed a year-round solution that would make their entire home comfortable no matter the season.

Solution: Installed a Mitsubishi ductless heating and air conditioning four-zone Hyper Heat unit.  Indoor units were installed in the living room, family room, office and master bedroom to provide maximum comfort all year long. 

Our homeowners heat was inadequate and they needed a permanent solution for cooling as well.  Mitsubishi ductless AC unit installation was an obvious solution for cooling and the new, super-efficient Hyper Heat system added the needed heating options for those hard to warm spots throughout the home.

By designing a four-zone system, we made sure that different areas of their home could be adjusted to maximize comfort without adjusting the temperature of the whole home.

With the old oil-based radiator system still in place, this multi-zone ductless solution allows customization - the bedroom can be toasty while the office remains cool.  They can even cool off the family room during the day if it gets a little too much sun!

Zones allow this customization of temperatures, easily and efficiently. Now there are no more arguments over the thermostat because these homeowners don’t have to settle for one-size fits all heating and cooling.  That comfort and convenience will give this family many more years of comfort in their beautiful Tewksbury location.

Saving Money with Rebates

Mitsubishi ductless air conditioning is part of the Massachusetts MassSave program, which helped this couple get a rebate of $250 on this installation!  

Due to the energy efficient technology involved, rebates are issued for systems like this because they help out the environment. These ductless split system ACs can you save significantly when compared to traditional heating with fossil fuels, like the oil-burning hot water system in this home.

There are still rebates available, so if you are interested in making the switch to energy efficient equipment, be sure to ask your specialist about what sort of rebates would apply.

Let’s recap the key points of this home:

• The home owners now have a comfortable, quiet solution to heat and cool four prime areas of their home.

  No removal or replacement of equipment was necessary and the newly installed equipment is out of the way.

• The four-zone system with one outdoor unit is a cost-effective way to deliver maximum comfort with a small footprint.

• $250 rebate was available to the homeowners and the increased efficiency will save them money on energy bills all year long.

A Great Investment

Problem: Many areas of the home weren't getting the proper heat - or AC - they needed.  The living room, family room, office/computer room and master bedroom are the most used areas in the home and we were tasked to make them fully comfortable. In order to do this, we had to stop the "freeze/thaw" cycles the homeowners felt going from room to room. 

Solution: Installed a Mitsubishi ductless heating and air conditioning four-zone Hyper Heat unit.  Indoor units were installed in the living room, family room, office and master bedroom to provide maximum comfort all year long.

This lovely colonial-style home in Newton, MA needed additional heating and cooling. The homeowners wanted to convert one of the bedrooms into a music studio, so having great climate control AND noise reduction was key. They also wanted to ensure the recording they did wouldn’t have the distracting hum of traditional window air conditioners or the noise from fans that are amplified if caught on sound recording equipment. We knew we had to balance comfort and ambient noise to meet the goals of our client. We were able to design a great system using Mitsubishi Hyper-Heating technology that will be able to deliver quiet, efficient heating and cooling for this space while saving our homeowners on energy bills.

Problem: The homeowners were converting a bedroom into a music studio, which would require the room to have adequate climate control for instruments and equipment and a quiet system to prevent "artifact" noise when they were recording music.

Solution: N.E.T.R. Inc. installed a Mitsubishi Hyper-Heating ductless unit to provide additional heating and cooling to supplement their existing gas heat while providing extra quiet cooling during the spring and summer.

Uneven heating and cooling can make some areas of a home less popular, and that's a shame, especially when it comes to areas like a family room, which is meant for folks to get together and spend time as a family. This is a common problem with bonus rooms, finished basements or attics, or a lower level family room like the one in this Winchester, MA home. The homeowners had a pellet stove they were using, but they found it was providing inconsistent heat and had significant maintenance issues. The pellet stove was difficult and timing consuming to clean, hauling pellets was a burden, and it was becoming more and more expensive to heat the home in this manner.

We do a lot of jobs in the gorgeous homes of Boston's South End, so when we got a call from a homeowner on Upton Street, we were familiar with the problems they were experiencing. All we needed to do was assess the current system and install a solution that would complement what was already in place.

Problem: The existing system didn't provide AC to the four-story Brownstone evenly, effectively or efficiently. 

The Ideal Air Conditioning Solution for a Boston Brownstone

In the end, we chose a textbook Brownstone solution.

Based on the homeowner's wish to have absolute control over the temperature in every room in the house, we recommended a five head multi-zone unit from Mitsubishi.

Because we can run all five heads off the same outdoor unit, which keeps the cost under control, we were also able to make this install quickly and efficiently.

We dropped the condenser on the back patio and hid the line in a piece of crown molding, so it blends right in with the brick. All in all, the installation was seamless and didn’t interfere with the home’s beauty.

People have all different kinds of concerns or problems when they call us, but this is one of the most common problems we come across. This homeowner from West Roxbury in Boston was having trouble heating and cooling particular spaces in the home. The areas of concern were the basement, and a bedroom with cathedral ceilings. They didn't want to get rid of their old system but see if there was something they could add or adjust to comfort these spots.

The Ideal Heating and Cooling Solution for This West Roxbury, Boston Home

One of NETR's experts went out to help the homeowner find the right solution.

The homeowner decided to have Mitsubishi ductless units installed in the areas where there were problems with the heating and cooling. This has now become the primary source of heating in the winter, and cooling in the summer.

Between the savings on the rebate, lower energy bills, and improved air quality in the home, this homeowner was very pleased with the end result!

Heating your home using oil is a common practice in the Boston area. You fill up, and you get your oil refilled when needed. We came across a man in Burlington who wanted to switch out of oil heat. The prices for oil were low at the time, but he knew they could go up, and didn't want to be worried about refilling the oil.

Solution: An electric heat pump from Mitsubishi will replace his oil heating solution.

one of our comfort consultant specialist at NETR went out to check out the home. He thought a single heat pump would do the trick, which you can see in the photo above. This switch from oil to electric will help to keep the energy bill lower, and more predictable.

Problem: The existing oil heating system was alright, but the homeowner wanted lower energy bills, without having to refill oil.
