Homeowners who are thinking about how to cool or heat an area of the home without extending the duct system for the central HVAC system often turn to the ductless mini-split. It’s a heat pump, but it works with just a condenser that’s connected by a conduit for wiring and refrigerant to an indoor air handler. There are no ducts. Some models can accommodate as many as four air handlers, which can then be placed strategically in the home. 

Let’s weigh some of the benefits and drawbacks of ductless HVAC so you can make a more informed decision.

Cons of Ductless HVAC Mini-Splits

  1. It may not heat as well as a furnace during freezing weather. One of the main drawbacks of the mini-split has always been that they don’t heat the home as well as a furnace when temperatures plummet below freezing. They then revert to a radiant heater, which can be expensive to run during extended cold periods. Or, the system may default to a central heating system. However, mini-splits have been improved in recent years to be more reliable for heating.
  2. Mini-splits can be expensive. Ductless HVAC systems are often perceived as being expensive. Furthermore, they may not last as long as a central system. However, the savings in energy bills may offset some of the costs of purchasing the equipment and the installation.

Pros of Ductless HVAC Mini-Splits

  1. Ductless mini-splits are efficient. Ductless systems are considered one of the most efficient air-conditioning/heating systems available. Homeowners report as much as a 30% annual savings on energy bills.
  2. Air handlers are versatile when it comes to placement. Air handlers are available that can be mounted on the ceiling, the floor, a shelf, or the wall. They are very versatile in your room arrangement.
  3. Ductless mini-splits cool and heat in a pleasing manner. The heated and cooled air comes out in a gentle stream rather than a big blast like central heating and cooling. Furthermore, mini-splits are quieter.
