Ductless Mini Split Installation | Just Call Heritage

Central air conditioning is a great addition for comfort, but if your home doesn’t have existing ductwork, then you may have resigned yourself to cumbersome window AC units each summer. The good news is that recent developments in technology have made it possible to install permanent and fully controllable air conditioning, all without the need for ductwork.

Commonly called mini-split or “ductless” air conditioning systems, these units provide the same performance as central air conditioning without the need for ductwork, and are installed through a combination of an outdoor unit (condenser) and an indoor unit (evaporator). Instead of using ductwork to circulate air through a series of registers and returns, and back to your furnace’s air handler to be cooled, ductless systems use an indoor unit (commonly mounted to the floor or wall) to circulate and cool air directly from the unit.

If you don’t have a furnace or existing ductwork in an area of your home that needs AC, there’s a good chance a mini-split system could be right for you.

Mini-split systems can be installed almost anywhere, provided there is a good location for the outdoor unit and indoor unit(s). Indoor units can be installed in almost all locations, either on the floor or on a wall or ceiling. Each indoor unit contains its own local temperature sensor and can be individually controlled from a remote control or with the correct upgrade package, even your phone. If seasonal allergies are a concern, they can also be fitted with enzyme filters that eliminate allergens and irritants inside your home.

As a side benefit, all of our Heritage installed ductless systems double as heat pumps during the colder months, essentially acting as an AC system in reverse. Most standard units are effective down to about 35 degrees, or you can upgrade to a Hyper Heat system so you can heat your home all year round, even down to -13°F. And, depending on the layout and size of your system, ductless heat pumps can actually heat your home more efficiently than traditional fossil fuel systems like gas or oil, saving you money during the heating season.

The short answer is yes! Even if you have a central heating and cooling system, you can still benefit from a ductless system in areas of your home without existing ductwork such as a new addition, workshop or garage, and even finished basements.

Typically, existing ductwork has not been designed to accommodate additions or renovations, and therefore is only sized to meet the exact airflow requirements of your existing setup. This makes it either impossible or too costly to add a new “zone” to existing ductwork. In this situation, a mini-split solution may be a better option.
