How Much Energy Do Mini-Split Systems Use?

HVAC systems offer essential climate control functions but can be expensive and challenging to operate. Many homeowners use mini-splits to keep their residences comfortable while saving money on energy bills. Learn about the factors that determine how much energy mini-split systems use.

The Size of the Space

The amount of energy mini-splits use depends on how much space they heat or cool. Large spaces require more time to get to the desired temperature, resulting in increased energy usage.

Mini-splits are designed to work in small spaces, making them much more efficient than traditional HVAC units. Calculating the room size before installation will ensure your unit operates efficiently. Small areas less than 400 square feet require around 9,000 BTUs (British thermal units), while areas over 1,000 may need up to 24,000 BTUs.

The Unit’s Capacity

While small units are effective in limited areas, large spaces require bigger units. The amount of hot or cold air your mini-split can produce will significantly impact the amount of energy it uses.

Powerful systems consume a lot of energy, increasing your electric bill. It also depends on whether you use an additional mini-split or HVAC system. Using multiple mini-split units in a single home can reduce the strain on each, reducing energy use.

Your Home’s Insulation

Your home’s insulation also impacts your mini-split’s energy usage. If air escapes through doors, windows, and gaps in the walls, keeping the space at optimal temperature will be much more challenging.

The biggest problem with traditional HVAC systems is air loss due to leaky ducts or poor performance. A ductless mini-split AC system uses a compressor outside the home to pump air directly into the space, reducing the amount of air lost.

The Temperature Outside

The temperature outside will have the most significant impact on your mini-split’s efficiency. Mini-splits use refrigerant to move heat from one place to another. However, if it’s extremely hot or cold outside, they’ll have to work harder; this strain can reduce performance over time.

Mini-splits work best when operating in moderate climates. If the temperature exceeds 100 degrees Fahrenheit or goes below freezing, it can impact the equipment. Homeowners who live in extremely hot or cold areas must pay attention to the weather conditions and have a backup HVAC unit in case things get extreme.

Enjoy Your Home in Comfort

Your HVAC system is essential for ensuring your home has a comfortable climate, regardless of the weather outside. Knowing how much energy your mini-split system uses will allow you to tailor your lifestyle to your needs and live more comfortably.
