Ductless mini-split heat pumps still rely on electricity to warm and cool

your home. For those who use heating oil, that means a step away from 

a finite resource. However, these systems are also far more efficient than 

central HVAC units and vastly better at cooling than window units.

  • Supply heating and cooling to any room in your home.
  • Set different temperatures in independent zones.
  • Eliminate the need for ductwork with a ductless system.
  • Reduce energy consumption with energy efficient operation.
  • Reduce dust, dirt, and germs in your home with built-in air filtration.
  • Save money on heating & cooling with energy efficient performance.
  • Reduce noise with silent operation

Choose Which Rooms to Heat and Cool

With central heating and cooling systems, you don’t really have much control over choosing which rooms to heat and cool. This results in inefficient energy consumption, as you'll likely be paying to heat and cool rooms that you don’t use. 

A ductless mini-split heat pump solves these problems by providing full control over the temperature in every room of your home. Specifically, you can:

  • Heat and cool only those spaces you want.
  • Increase energy savings with more control over energy usage.
  • Reduce energy wasted in unused rooms by controlling their temperature.
  • Customize the temperature for each room to the perfect comfort. 
Reduce Allergens

Reduce Allergens with Air-Filtration

Indoor air quality is often worse than outdoor air quality. A great deal of that is due to the dust, pollen, pet dander, and bacteria that settles into your air ducts and then gets blown around. You can change the filter on your system regularly and still experience high amounts of dust and bacteria, particularly if condensation is present in the ducts or registers. With a ductless mini-split system, you can:

  • Improve your indoor air quality with built-in air filtration.
  • Reduce symptoms of asthma, COPD, and other breathing conditions.
  • Eliminate the possibility of mold or bacteria growing in your ductwork.
  • Enjoy purer, fresher air in your home.

Eliminate The Need for Ductwork

Ductwork is responsible for transporting heated or cooled air from the central unit to each room in the home. Installation can be expensive and messy, requiring large, bulky ductwork to be built into walls and ceilings.

Another high cost comes from the inefficient operation as the result of energy lost due to holes, leaks, and gaps in duct connections. The U.S. Department of Energy reports that this can be as much as 20 to 30 percent of the air moving through a duct system--which amounts to 20 30 percent more in costs. Over time, the insulation on your ductwork can also fall away, decreasing your system’s efficiency and performance.

A mini-split heat pump system can solves these problems with a ductless solution. By using thin, flexible hoses to connect the interior and exterior units, a ductless mini-split makes for a clean and quick installation. And the performance is much more efficient without the problem of energy loss.

  • Reduce energy loss from air leaking out of ductwork. 
  • Increase energy savings with an efficient ductless system.
  • Eliminate extra maintenance of regular ductwork cleanings.
  • Avoid the messy, expensive construction with ductwork installation.

Eliminate space heaters and AC window units

Space heaters and AC window units are inconvenient ways of supplementing heating and cooling. Not only are they loud and ugly, but their energy performance is inefficient and expensive to operate. A mini-split heat pump solves all these problems:

  • Replace both your window unit and space heater with a single mini-split.
  • Enjoy more floor space without space heaters cluttering the room.
  • Gaze out the window without an AC units blocking your sight.
  • Stop lugging space heaters and AC window units in and out of storage.

What You Need To Know About Heat Pumps

Do heat pumps work at extremely low temperatures?

Yes, heat pumps can function at extremely low temperatures. Previously, some heat pumps performed better in cold climates than others. However, thanks to technological advances, most heat pumps on the market today can keep you and your family warm on even the coldest of Boston winter days.

Why didn't heat pumps always work well in cold climates?

Most heat pumps today work well in extremely cold climates. However, this was not always the case.

Why? Because heat pumps simply transfer outdoor heat indoors rather than heating homes or office buildings. Heat pumps are extremely efficient because they do not generate new heat by burning fuel.

Certain older types of heat pumps struggle to perform efficiently when it's cold outside. This is because moving heat from a cold area (outside) to a warmer location (inside) takes more energy. This could be a problem because the heat pump would need to constantly move heat into the house to keep it comfortable.

Fortunately, many newer heat pumps have improved their ability to withstand cold temperatures. Below, learn how heat pump technology has evolved to perform well in even the coldest climates and how to select the right heat pump for your home.

Which heat pump works best in cold climates?

The most common type of heat pump is an air-source heat pump. They heat the house or office building with outside air.

Air-source heat pumps were once thought to be inefficient in cold weather. This is due to the fact that the colder the air outside, the more difficult it is for the heat pump to find heat to transfer into the home.

However, technology for air-source heat pumps has improved significantly in recent years, and this equipment now performs well in extreme climates. Several components of the air-source heat pump have been improved, such as coil design, electric motor, and two-speed compressor designs.

The following technological advancements have contributed to improved performance in cold weather:

  • Thermostatic expansion valves for more accurate refrigerant flow control to the indoor coil.
  • Variable speed blowers to improve efficiency and combat the energy-sucking effects of dirty air filters, coils, and clogged ducts.
  • Internal groves in copper tubing to increase surface area.

These are just a few of the advancements that make air-source heat pumps an efficient and cost-effective option, even in Boston's freezing winters.

A type of air-source heat pump is the ductless mini-split heat pump. This system is ideal for homes with non-ducted heating systems such as radiant panels and space heaters. They may also be viable for rooms or homes where adding or installing new ducts would be impractical.

The benefits of ductless, mini-split heat pumps include their small size and ability to heat and cool individual rooms, a process known as zoning, which saves energy.

How to Select the Best Heat Pump for Your Home

Research can provide you with a basic understanding of your heat pump options. Even if you've decided on the type of heat pump you want, you should still investigate the various features to determine exactly what you want for your home.

For example, if you are considering an air-source heat pump, you should think about the following:

  • What is this heat pump's heating season performance factor (HSPF)?
  • Is there demand-defrost control on this heat pump? This could reduce the number of defrost cycles and the amount of supplementary heat required to heat the home on the coldest winter nights.
  • What is the heat pump's outdoor sound rating? The Department of Energy recommends a rating of 7.6 bels or lower.

FAQ / Tips

How many square feet does a mini split cool?

A mini split can cool a large house – over 3,000 square feet - if the equipment has the appropriate BTU rating. Depending on factors like geographic location, ceiling height, insulation depth and the extent of windows, you can expect to need 25 to 60 BTUs per square foot of living space.

For a more detailed discussion on ensuring you have the right size, check out our guide here.

How are ductless mini splits installed?

The installation process for a mini split system is much easier than that of a traditional system. In fact, most DIY systems follow a 3 step process of:
Installing the condenser (outside)
Running pre-charged refrigerant lines through a 3-inch hole in the exterior wall
Installing the air handlers (indoors), attaching the refrigerant lines

How Much Do Ductless Systems Cost to Install?

The cost to install your ductless air conditioning system will depend on several different factors. First, there is the cost of your outdoor unit, which can depend on both the model you select and the unit’s efficiency. More efficient units, obviously, will be more expensive. The number of indoor units that you need will also determine the overall costs of your system. As the number of air handlers increases, so will the installation cost.
