Stay Comfortable with Ductless Cooling in Your Massachusetts Home

If installing HVAC ductwork in your older MetroWest home is too expensive a proposition, mini-split air conditioners can offer a cheaper and more flexible solution.

Advantages of mini-split systems

Ductless mini-split air conditioners are small and compact and can be mounted on walls or floors. Since the units are installed in individual rooms, they allow zoned heating and cooling. Why pay to cool rooms that don’t need it? This means lower utility bills because you’re not paying to cool a room that you’re not in.

Other advantages of mini-split systems include:

  • Cooling of more than one room. Up to four indoor units can be connected to one outdoor unit.
  • Installation flexibility. Suspend the inside unit from a ceiling, mount it flushed into a drop ceiling, or hang it on a wall.
  • Reduced noise. Because all of the loud components are located outdoors, ductless mini-splits are much quieter than AC window units.
  • Easy installation. Only needs a small, 3-inch hole to be installed.
  • Wherever you put the indoor unit, you can control it with a remote control.
  • More energy efficient than window units.

Alternatives to ductwork

According to, mini-split systems offer flexible air conditioning options when the cost of extending ductwork is too expensive:

Most manufacturers of this type of system can provide a variety of lengths of connecting conduits, and, if necessary, you can locate the outdoor unit as far away as 50 feet from the indoor evaporator. This makes it possible to cool rooms on the front side of a house but locate the compressor in a more advantageous or inconspicuous place on the outside of the building.

Mini splits have no ducts, so they avoid the energy losses associated with the ductwork of central forced air systems. Duct losses can account for more than 30 percent of energy consumption for space conditioning, especially if the ducts are in an unconditioned space such as an attic.

  • Francis from Nicholson Plumbing and Heating was excellent. He was here to evaluate HVAC in our home. He was very patient and answered all my questions. He is also polite and easy to communicate with him. He explained technical concepts to me in layperson terms!

  • Nicholson offered what is possibly the best customer service I have dealt with in a home repair situation.  I called them because I was looking to replace my very old furnace.  They came out to do an initial estimate, and then came back when I had some further questions about my options.  After installing the furnace, they ran into some problems with my air ducts.  This happened on a Friday, and the problem was fixed by Monday afternoon.  In addition to their excellent service, they did quality work at a fair price.  I would recommend them to anyone looking for an HVAC company in the Framingham area!

  • Recently used these guys because my HVAC unit AC wasn’t working (first hot day of summer).  Showed up on time, wore booties, fixed the unit.  During the visit we talked about how my unit was having problems in the winter – which was resulting in NSTAR service calls of maybe 3-4 times per season (I am on a service plan with them).   He was the first guy to tell me WHY the problem was happening, and HOW to fix it.  I find it strange that all of the NSTAR guys etc. no one took time to point out how to fix the source of the problem…Very professional, smart.  I would use them again, and plan to for the fix on my heating unit!
