Mini split

Are mini-split ductless systems efficient?

In the height of the summer heat, staying cool is essential. Many homeowners are familiar with a central AC system, but that's not the only option.

Mini-split ductless systems can work well year-round, keeping a home cool in the summer and warm in the winter. As the name implies, these systems don't need air ducts to function, instead relying on heat pump technology (an evaporator combined with a condenser) to cool and heat a home. Due to their versatility, these systems can be a great option for New England homeowners.

Mini splits aren't the best fit for every home, however. As always, it's important to evaluate your needs, budget and environment to determine whether it's the right option. One important question to consider is: Are mini-split systems efficient?

Are mini-split systems efficient?

Mini-split systems are incredibly efficient in the right circumstances. Each mini split unit, or head, is controlled by its own individual thermostat – which means that you can control the temperature of different areas in your home. Not using your bedroom much during the day? Turning off the mini-split unit in that room can increase energy efficiency and cost savings. Mini splits also use electricity rather than gas, which comes with some advantages.

Mini-split unitMini splits work best for homes that are under 1000 square feet, or for homeowners that only want to heat or cool specific areas of their house. For example, mini splits could be perfect for a renovated garage or an upstairs room that is difficult to run a duct to. Smaller beach cottages or lake houses would benefit from a mini-split system; homeowners could potentially enjoy the home throughout the winter months.

Larger homes will most likely benefit from a central HVAC system, however. Mini-split systems make sense when there are 2 or 3 units in a home, but for homes that require 7 or 8 units, it doesn't make as much sense – especially because there is a significant efficiency loss as you add more refrigerant lines.

It's also important to evaluate the level of insulation and sealing before you install a mini-split ductless system. Poorly insulated homes are not typically a good fit for mini splits; the ductless systems won't be as efficient to compensate the loss of air. That being said, even a powerful central AC system would use (and lose) a lot of energy in those situations.
