Quiet, per-unit comfort your residents and guests will never have to think about.
In premium condos, luxury apartments, and boutique hotels, comfort is the product. A guest remembers a room that stayed silent and perfectly even through the night; a buyer remembers a residence that felt calm the moment they walked in. Waterless DX radiant heating and cooling gives every unit its own independent zone, its own setpoint, and its own schedule, so each home or room is conditioned for the people in it, not for the floor plan. Radiant floors warm from the ground up while matched air handlers handle cooling and humidity, all at roughly 20 dB(A) indoors, quieter than a library reading room and far below the hum and rattle that drive HVAC noise complaints. Because each unit meters its own energy, operators can sub-meter usage and set unoccupied rooms back automatically, while keeping central visibility across the whole property. One refined system, individually zoned, individually metered, centrally managed. Purpose-built for your quality life.
Can each unit and room hold its own temperature?
Yes. The system zones each unit independently, and each room within a unit can be its own zone with its own setpoint and schedule. Refrigerant to every floor loop is metered by electronic expansion valves in a per-unit zone-control box, so residents and guests get true room-by-room comfort rather than a single building temperature imposed on everyone.
Common Multifamily & Hospitality Challenges
We understand the unique production challenges your industry faces. Here's how we address them.
HVAC noise drives complaints and lost reviews
Noise is consistently one of the top guest complaints in hospitality, and a humming, rattling, or cycling in-room unit is one of the fastest ways to lose a five-star review or a repeat resident. Forced-air systems push sound through vents and ducts all night long. Waterless radiant floors heat by radiation rather than blowing air, and matched indoor units run near silently at roughly 20 dB(A), so the only thing a guest notices is how well they slept.
One building temperature can't satisfy every unit
A single central setpoint leaves half the building too warm and the other half too cold, and every override means a service call or a thermostat war. Premium residents and guests expect their own climate, on demand. The system treats each unit, and each room within it, as an independent zone with its own setpoint and schedule, so comfort is tailored unit by unit instead of imposed building-wide.
No clear way to meter or set back energy per unit
Without per-unit metering, operators and condo boards can't fairly allocate energy costs or trim waste in unoccupied units, and central systems keep conditioning empty rooms around the clock. Each unit meters its own energy and reports usage, so consumption can be sub-metered to the resident or room and unoccupied units set back automatically, all while management retains a property-wide view.
Solutions Built for Multifamily & Hospitality
Per-unit zoning, metered and managed centrally
Refrigerant flow to each floor loop is metered by electronic expansion valves in a per-unit zone-control box, so every dwelling and every room holds its own temperature and schedule. The same architecture reports energy use per unit for fair sub-metering and automatic setback of vacant rooms, while a property dashboard and app keep management in control across the whole building from one place.
Smart Zoning & App Control →Near-silent comfort that protects the guest experience
Radiant floors deliver even, draft-free warmth from the ground up, and matched low-static air handlers manage cooling and humidity at roughly 20 dB(A) indoors, with no rushing vents, no ductwork rattle, and no boiler cycling at 3 a.m. Steady temperature, balanced humidity, clean filtered air, and true quiet are held together as one standard, so every room feels like a calm, well-run suite.
5-Constant Comfort →Heating, cooling, and hot water on one refrigerant platform
Rather than stacking boilers, chillers, and separate domestic hot water plant, one air-source heat-pump platform delivers radiant heating, air-handler cooling, and hot water across the property. Fewer systems mean a smaller mechanical footprint, simpler maintenance for building staff, and a cleaner path to the efficiency targets that condos, apartments, and hotels are now held to.
Products for Multifamily & Hospitality
Per-unit zone-control & metering box
A per-unit valve box using electronic expansion valves meters refrigerant to each floor loop, giving every dwelling independent room-by-room zoning. Low-voltage thermostats and a connected app provide remote on/off, setpoint, scheduling, and per-unit energy monitoring, the foundation for sub-metering and automatic setback of unoccupied rooms.
Low-noise concealed air handlers
Slim, concealed refrigerant air handlers (fan coils) carry the cooling and humidity load so the floor is never used as a cooling surface, avoiding condensation. They feature high-efficiency filtration, sterilization, and self-cleaning, run near silently at roughly 20 dB(A), and include a built-in drain pump for flexible placement in tight guest-room and unit ceilings.
Waterless DX radiant floor loops
Refrigerant flows directly through corrosion-resistant copper capillary loops embedded in the floor, delivering even far-infrared warmth with no water in the floor, no loop to drain between guests or seasons, and no risk of an embedded water leak across the units below. Loops can be fitted with isolation valves so one room can be serviced without disturbing the rest of the unit or building.
Per-unit comfort and metering across a premium residential community
Challenge
A developer building a premium multi-unit residential community needed comfort that felt bespoke in every dwelling: independent per-unit temperature control, true quiet in bedrooms, fair per-unit energy metering for the owners, and central manageability for the building team, all without a basement full of separate heating, cooling, and hot-water plant or the leak risk of hydronic loops stacked above occupied units.
Solution
Working with our manufacturing partner network, each unit was fitted with waterless DX radiant floor loops for even floor-up heat, matched low-noise air handlers for cooling and humidity, and a per-unit zone-control box metering refrigerant to each loop. Per-unit energy monitoring enabled sub-metering and automatic setback of vacant units, while a single platform covered heating, cooling, and hot water and a central app kept management in control across the property.
Result
Every dwelling holds its own temperature and schedule at roughly 20 dB(A) indoors, with no water in the floor and no audible mechanical noise in living and sleeping areas. Energy is metered unit by unit for fair allocation, unoccupied units set back on their own, and the building team manages comfort across all units from one place, as one coordinated system rather than a patchwork of equipment.

Frequently Asked Questions
Very quiet. The indoor air handlers run near silently at roughly 20 dB(A), and because radiant floors heat by radiation instead of blowing air, there are no rushing vents, no ductwork rattle, and no boiler cycling overnight. Since HVAC noise is one of the most common drivers of hotel complaints, near-silent operation directly protects guest satisfaction and reviews.
Yes. Each unit meters and reports its own energy use, which lets operators and condo boards sub-meter consumption to the resident or room and allocate costs fairly. Unoccupied units can be set back automatically to cut waste, while building management keeps a property-wide view and central control through the dashboard and app.
Yes. One air-source heat-pump platform delivers radiant heating, air-handler cooling, and hot water, which reduces the mechanical footprint compared with separate boilers, chillers, and hot-water plant. Per-loop isolation valves let staff service a single room without disturbing other units, and the technology has been delivered at scale, with more than 690,000 sq ft installed and in service since around 2017.
There is no water in the floor. Refrigerant flows directly through embedded copper loops, so there is no hydronic loop to drain between seasons or guests and no risk of an embedded water leak spreading into the units below, a serious concern in stacked condos, apartments, and hotels. The result is even radiant comfort with far less long-term water-related risk.
