Last week, we announced the launch of our Ductless on Every Job campaign, which aims to encourage contractors to consider ductless as a solution on every call. On the blog, we’re running biweekly posts that focus on specific installations or situations where contractors can offer ductless as a home comfort solution. This week, we’re highlighting older homes.

September 18_Ductless Older Homes_Image 2The existing home market is growing. According to the National Association of Realtors, existing home sales are up 6.5 percent, the National Association of Home Builders reports that home improvement spending is up 7 percent over the previous year and the median age of the American home is around 36 years. If you haven’t been on a sales call for an older home yet, you’re going to find yourself on one sometime soon.


Here are some common issues associated with cooling and heating older homes and ways that a ductless solution can address them:


The existing HVAC systems in older homes are outdated and ineffective. Let’s face it: HVAC systems in homes that are more than 30 or 40 years old are simply not effective. They run inefficiently, sending energy bills through the roof, and the outdated technology can’t adequately heat and cool the space.

Some older homes have no existing ductwork. Often built before central heating and air conditioning were widely available, many older homes have no ductwork at all. A unitary system would require extensive construction and are costly, time intensive and a huge disruption to the homeowner’s daily life.

With a ductless solution, the indoor air handlers are either wall- or floor-mounted and require no ductwork, so homeowners can avoid the enormous cost and inconvenience of installing ductwork.

Ductwork requires extensive space. To retrofit ductwork in an existing home requires taking away from space to make way for the ducts. Ceilings would be lowered or space would have to be carved out of the rooms.

Unlike ducted systems, the footprint of a ductless system is very small. The bundle of refrigerant piping and wires is so compact that only a 3-inch opening in the wall is required to run the lines connecting the indoor unit to the outdoor unit.

Many older homes feature historic architecture. For many homeowners, part of the appeal of an older home is the architectural charm of older structures. Moldings, large windows and other details throughout these homes could be compromised in order to accommodate ductwork.

A ductless solution will modernize the home while keeping the architectural integrity intact. The National Park Service (NPS) and Secretary of the Interior Standards and Guidelines for Rehabilitating Historic Buildings have recognized ductless systems for their ability to help maintain this historic character.

To see how our ductless systems were able to meet the needs of a historic renovation, check out this case study of the the Waggoner Family home in Washington, D.C. – a nearly 90-year-old house that cut its energy bills by 87 percent with Mitsubishi Electric ductless zoning systems.
