Adding Cooling to a Home With No Ductwork in Mount Rainier

A Mount Rainier case study in bringing air conditioning to a home built for radiators.

The Problem

A Mount Rainier household lived in a historic home heated by radiators — comfortable in winter, but with no ductwork anywhere and therefore no central air conditioning. Through our humid summers they relied on window units that were noisy, unsightly, and uneven, and they were tired of it. They wanted proper, whole-home cooling but faced the obvious obstacle: a home built for radiant heat has no ducts to carry cooled air, and adding conventional ductwork to a historic house is invasive and costly.

What We Found

The situation was a common one for Mount Rainier’s radiator-heated homes: excellent heat, no path for central cooling. Retrofitting ductwork through a historic home would mean tearing into walls and ceilings, sacrificing closet and living space to chases, and risking the home’s character — a lot of disruption and expense for a compromised result. But the lack of ductwork did not rule out real cooling. The home was well suited to a ductless mini-split system, which cools without any ductwork at all, letting the beloved radiator heat stay exactly as it was.

The Approach

We designed a ductless solution for the home. Ductless mini-splits use one or more outdoor units connected to slim indoor units by small line-sets, each cooling its area with only a minor penetration through an exterior wall — no ductwork, no major construction. We planned the number and placement of indoor units to cool the home evenly while keeping the visual impact minimal, and sized the system to control our summer humidity properly. The radiator system was left untouched to keep providing winter heat. The result is a home that keeps its historic radiant heat and gains modern cooling, each doing what it does best.

The Outcome

The household finally had genuine, even, whole-home cooling through the summer — quiet and efficient, with the window units gone for good — while keeping the radiator heat they valued in winter. The home’s character was preserved, since no ductwork had to be forced through its walls and ceilings. It is a textbook Mount Rainier solution: for the many historic homes here that were built for radiators and never had ducts, ductless mini-splits are often the ideal way to add real cooling without compromising the home. Heat and cooling, each suited to the house.

Frequently Asked Questions

My radiator-heated home has no ductwork. Can I still get air conditioning?: Yes, through a ductless mini-split system, which needs no ductwork at all. Many historic Mount Rainier homes were built for radiant heat and never had ducts, which rules out conventional central air without a costly, invasive ductwork retrofit — but ductless solves exactly this. Outdoor units connect to slim indoor units by small line-sets, each cooling its area through only a minor exterior-wall penetration, with no major construction. Multiple units can cool a whole home evenly. Your radiator heat stays exactly as it is for winter, and you gain efficient, quiet cooling for summer. For a no-duct home, it is usually the ideal way to add real air conditioning.
Isn’t it better to just add ductwork for central air?: For a historic home built without ducts, usually not. Retrofitting conventional ductwork means tearing into walls and ceilings, giving up closet or living space to duct chases, and risking the home’s character — a lot of disruption and expense, often for a compromised result in a house that was never designed for it. Ductless mini-splits avoid all of that, delivering efficient, even cooling with only small line-set penetrations and no major construction, while leaving your radiator heat untouched. For most radiator-heated homes in Mount Rainier, ductless is both less invasive and more sensible than forcing ductwork into a home that was built for a different kind of comfort.
