What Size Ductless HVAC Do I Need? A Guide

Many homeowners choose ductless mini-splits, which are helpful for home heating and air conditioning. These devices consist of individual wall-mounted indoor air units and an outdoor compressor, allowing for increased temperature control in each space containing a unit.

While these systems are quieter, packed with energy efficiency, and easier to install than standard HVAC units, you must consider some vital aspects before installing one at home. As the name suggests, a ductless mini-split functions without requiring ductwork, making them a viable option for many home designs; however, it’s still important to know just what size your unit needs to be. Below, we discuss why selecting the proper size ductless unit is crucial and what you must consider when deciding.

Importance of Correctly Sizing Your Ductless Unit

When you’re in the market for a new ductless mini-split, you must ensure that all the boxes are ticked for a successful installation. One crucial aspect is the size of the unit.

 If your unit is too small, it won’t be able to regulate the indoor temperature effectively. If it’s too big, its efficiency will lack, and the unit will likely wear out more quickly than anticipated. By properly sizing your unit with the help of a professional, you can rest easy knowing your unit is designed and equipped to meet your heating and cooling needs year-round.

What To Consider When Sizing Your New Mini-Split

Having a checklist accessible when you undergo a new mini-split installation is critical. The British Thermal Unit, or BTU, is the rating used to measure thermal energy; it’s the amount of heat used to increase the temperature of 1 pound of water by 1 degree Fahrenheit. In addition to using BTU as your sizing chart, you should also consider the following:

• Ventilation and sealing: The indoor and outdoor units must be adequately ventilated to run efficiently. All open spaces should be properly sealed to prevent heating or cooling loss.
• Ceiling height: The height of your ceilings matters as the higher the ceiling, the bigger the room, regardless of the calculated square feet. A bigger room will require more heating or cooling for comfort, affecting the unit size needed.
• Climate: An important consideration is the climate in which you reside. Hot, humid climates require a greater focus on cooling, whereas brisk climates require more significant heating.
