Do Ductless Air Conditioners Use a Lot of Electricity?

Let’s look at the energy efficiency of ductless mini-splits.

ductless ac Worcester County, MAMany of the households that TF Complete Heating & Cooling serves in Bristol, Middlesex, Norfolk and Worcester counties lack ductwork. That means they don’t have forced air heating and cooling equipment.

In the winter, these homes generally stay warm with boilers, but they often must resort to loud, bulky, sunlight-blocking window air conditioning in the summer. Our HVAC pros recommend that homeowners looking for a better cooling option consider ductless air-conditioning systems, also called ductless mini-splits.

How Ductless Mini-Splits Work

Ductless mini-splits use heat pump technology to cool your spaces without needing ductwork. These systems consist of two main components: an outdoor condenser and an indoor air-handling unit. These two parts are connected by a refrigerant line that runs through your outdoor walls. The system extracts heat from indoor air and transfers it outside to make your home cooler and less humid.

How Much Electricity Does Ductless A/C Use?

One helpful calculation notes that the average ductless mini-split uses an average of 600 watts of electricity — or 0.6 kWh per hour. This can result in some considerable energy savings compared to both central air conditioning and window A/C units.

Ductless Mini-Splits vs. Window Units

Window A/C units generally have a fixed compressor speed that doesn’t allow for efficiency adjustments. Additionally, these units are notorious for allowing cooled air to escape. That makes them incredibly inefficient.
By contrast, the air handlers in a mini-split don’t require large openings in your home, and they use inverter technology to cool your house more efficiently.

Ductless Mini-Splits vs. Central A/C

If you’re choosing between installing a central A/C system or ductless mini-splits, your cost considerations should begin with the installation. A home without ducts will need significant alterations to accommodate a central A/C. You will likely need to give up some amount of living space to install ductwork, and the process could be expensive and disruptive to your daily life.

Ductless A/C installation is much less invasive. It normally involves only drilling to run refrigerant lines and mount equipment. Mini-splits also have energy-saving benefits that can lower their electricity usage compared to central A/C.
