Multi-Zoned Ductless Mini Split System Gives Belmont Colonial Reliable Comfort

Beautiful colonial homes like this one in Belmont, MA are a joy to live in, except in the summer. Many of these homes were built long before air conditioning was even invented, so keeping them cool in our increasingly hot summers is becoming a real challenge. Many folks rely on window air conditioners, but these AC units have a lot of drawbacks.

Window ACs are a pain to install each year and they tie up your windows for half the year! These kinds of air conditioners are notoriously inefficient and drive up energy costs in the summer. On top of it, they’re noisy, which is becoming more of a problem as people, like our homeowners here in Belmont, are working from home more frequently.

Our homeowners were looking for a better solution to cool their kitchen, office, living room, and two bedrooms. They wanted something quiet, energy efficient, and cost effective. When they called us here at N.E.T.R., Inc., we knew we could install the perfect system to meet their needs.

Problem: The homeowners were relying on window air conditioners to keep the home cool, but the units were a pain to install and remove each year. They were also noisy and inefficient.

Solution: N.E.T.R., Inc. installed a Mitsubishi Hyper-Heating heat pump with four indoor wall units, creating four, individually controlled, zones of cost-effective comfort throughout the home.

Like many homes in our area, this family was unhappy with their window air conditioners. The window units did not circulate air throughout a room and both the noise and expense to run the AC units was enough to make this family know it was time for a change.

In addition to the everyday frustrations of window ACs, it usually takes the better part of a weekend day to install several units throughout a house like this one. Plus, finding the perfect weekend to install them is never easy! Often right when you decide to install there’s a cold snap, or you wait one to many, and spend a week sweaty and sticky. Rest assured, there is a better way available!

N.E.T.R., Inc. suggested the family install a Mitsubishi Hyper-Heating heat pump ductless AC system. Ductless air conditioners like these rely on one outdoor unit which connects to multiple indoor, wall mounted units that provide whisper-quiet comfort. The units distribute the air throughout a space and monitor its humidity as well, to help maintain perfect comfort at the touch of a button. For this home, we suggested installing four wall mounted units, one for the kitchen, one that would cool the living room and office, and one each for the upstairs bedrooms. Each of these units can operate independently, creating separate zones of comfort, and allowing you additional savings by only using the zones you need, when you need them.

These units provide great air conditioning in the summer but can also be used to supplement the existing heating system in the house in winter. Now, whenever it seems a little chilly, all the homeowners will have to do is use the remote control and nudge the temperature up to make the room perfectly comfortable. The heat pumps can provide great heat, even when it’s -13F outside, which means perfect comfort no matter what nature dishes out!

By cooling and heating areas without ductwork, there’s minimum disruption to the home, and ridding the family of their window ACs will allow them to enjoy their windows and the great light they provide in the home, all year long!

Saving Money- Rebates are Available

Because ductless systems are so energy efficient, many homeowners can qualify for rebates since these systems use much less energy and help the environment. These rebates, along with the savings you’ll see from lower energy bills every month, help to make switching to a more permanent cooling solution like ductless more affordable.

There are still rebates available, so if you are interested in this type of energy efficient equipment, be sure to ask your N.E.T.R., Inc. heating and cooling specialist about what sort of rebates would apply to your upgrade.

Let’s recap the key points of this home:

  • The home owners now have a comfortable, quiet solution that works both as heating and cooling for four different areas of their home.
  • No removal of any existing HVAC equipment was necessary- but they’ll never need those window air conditioners again!
  • The family will be able to work from home in the home office with no discernable background noise, while making working from home more comfortable than ever.
  • The family will also be able to use these units to supplement heat on cold winter days, assuring cost-effective, energy efficient comfort all year long!

A Great Investment

This installation will solve several of the problems these homeowners were facing. They are still using their current system to heat, so this ductless install will only supplement their current system to make the house completely comfortable, so no removal of an old system was necessary. The units were installed mainly to provide cooling in the summer months, and they can do so on demand- even on the occasional warm spring day. In addition, there’s no need to deal with those heavy, noisy window units ever again.

This technology will also help save money on energy bills, being that it is an energy efficient solution. Those kinds of savings are music to any homeowner who has seen their fair share of high electric bills in summer!
