Modernize aging guest-room HVAC, controls, and supporting systems.
Hotel HVAC modernization for occupied properties
We modernize aging hotel HVAC—room by room.
PerFitTech assesses, engineers, and delivers two-pipe retrofits and connected room controls—so hotels can improve guest comfort without closing the property or replacing qualifying infrastructure.

Why it matters
Modernize the room system without defaulting to a full-building rebuild.
PerFitTech evaluates the property as a whole—identifying what can be preserved, what should change, and how work can be phased around hotel operations.
01 / ROOM REVENUE
Limit inventory disruption
Coordinate room-level work around available inventory, renovation schedules, and occupancy periods.
02 / GUEST EXPERIENCE
Improve room comfort
Give individual rooms greater heating and cooling flexibility during difficult seasonal transitions.
03 / CAPITAL PLANNING
Preserve what still works
Retain qualifying piping, central equipment, and building infrastructure instead of defaulting to full replacement.
04 / OPERATIONS
Make performance visible
Add occupancy-aware controls, trend data, alarms, and remote diagnostic visibility around the room system.
Scope
Typical four-pipe conversion
Qualifying PerFitTech PMAC retrofit
Water piping
Can require separate hot- and chilled-water risers
May retain the qualifying two-pipe loop
Central plant
May include central-plant modifications
May preserve qualifying chiller and boiler infrastructure
Installation
Often involves significant room and corridor work
Can support planned room-by-room deployment
Capital plan
Often structured as a large construction program
Can be phased around budget and occupancy
Final fit and scope depend on installed equipment, enclosure dimensions, electrical capacity, controls, piping, water conditions, code requirements, and property operations. A site assessment confirms feasibility.
How the retrofit works
Four-pipe comfort from a two-pipe footprint.
PerFitTech applies Japanese-engineered PMAC/PAFMAC technology within a complete modernization service—from property assessment and engineering through controls, phased implementation, commissioning, and support.

Keep the two-pipe water loop
Retain core piping infrastructure instead of installing a second set of risers throughout the property.
Replace room fan coils with hybrid units
The built-in inverter heat pump lets the room deliver the opposite mode from the central water loop when needed.
Add room intelligence
Connect thermostats, occupancy sensors, door/window inputs, trending, and remote diagnostics around the equipment.
Available configurations: floor/console, ceiling/duct, and other application-specific units—subject to the property and selected PMAC/PAFMAC product.
Independent mode selectionEach room unit can select heating or cooling while retaining the two-pipe chilled/hot-water system.
Room-by-room replacementThe self-contained refrigerant circuit supports phased replacement without shared outdoor-unit refrigerant work.
Reheat dehumidificationPAFMAC can use the water coil for dehumidification and the heat pump for reheating to limit overcooling.
Hotel-ready engineeringPMAC publishes low-noise inverter operation, near-existing fan-coil dimensions, and a built-in drain sensor for U.S. floor units.

The PerFitTech process
Engineered around an operating hotel—not a vacant jobsite.
Our work connects site investigation, engineering, equipment, controls, implementation, commissioning, warranty, and service in one accountable path.
01
Assess
Review fan coils, piping, electrical conditions, controls, room inventory, and timing.
02
Engineer
Develop equipment selection, controls strategy, scope, schedule, and budget.
03
Pilot
Use representative rooms to confirm fit and operating procedures where appropriate.
04
Roll out
Install in planned batches around occupancy, renovations, and capital availability.

Keio Plaza Hotel: solving shoulder-season comfort
Nippon PMAC’s project story describes how the hotel retained its existing two-pipe piping while adding PAFMAC for year-round room-level heating and cooling. Before adoption, the hotel reported that seasonal comfort requests could reach approximately 20 in a day.

What we deliver
One modernization program from first survey to long-term support.
PerFitTech connects assessment, engineering, room equipment, controls, implementation planning, and lifecycle support—so critical handoffs stay coordinated.
Property & HVAC assessment
Evaluate room equipment, piping, electrical capacity, controls, operating priorities, and capital timing before defining scope.
See the assessment scopeEngineering & system design
Qualify the two-pipe system, select room equipment, and coordinate hydronic, electrical, controls, code, and constructability requirements.
Review engineering criteriaConnected room controls
Combine smart thermostats, occupancy inputs, trend data, alarms, and remote access into a hotel energy-management strategy.
Plan the controls layerImplementation & lifecycle support
Coordinate permitting, installation, commissioning, warranty, service, and VRF/VRV support around hotel operations.
See the delivery scopeMore than an HVAC retrofit
Connect comfort, operations, and equipment support.
PerFitTech brings the room unit, control strategy, hotel inputs, trend data, and service workflow together. The result is a comfort system designed around how hotels actually operate—not just how equipment is specified.
Plan a connected-room strategyGuest-aware room control
Coordinate thermostats, occupancy sensing, and door inputs so comfort and energy strategy respond to real room use.
Hotel-system integration
Where supported, connect PMS and room-status inputs to align HVAC operation with arrivals, departures, and occupied-room priorities.
Proactive engineering visibility
Use trends, alarms, and remote diagnostics to surface declining performance before it becomes a guest complaint or room outage.
Common questions
What hotel teams ask first.
Early qualification can begin with basic property information. Technical drawings and a site review can follow.
Potentially. Qualification depends on the fan coils, enclosure dimensions, piping and water conditions, electrical capacity, controls, code requirements, and desired performance. PerFitTech begins with a property-level review.
The approach is designed for planned room-by-room deployment in an operating hotel. Individual rooms must be available while work is performed; the sequence and inventory impact are confirmed in the implementation plan.
Yes, when property conditions allow. Rollout can be structured around occupancy, floor renovations, PIP work, or annual capital budgets.
Smart thermostats, occupancy sensors, door/window inputs, trend data, and remote access can be designed with the room equipment to improve visibility, maintenance, comfort, and energy strategy.
A conventional four-pipe conversion adds separate hot- and chilled-water piping so both modes are available. The PMAC approach is designed to create room-level heating and cooling flexibility while retaining the existing two-pipe loop, subject to property qualification.
It combines a hydronic coil with an inverter heat-pump circuit in the guestroom unit. Depending on design and operating conditions, the heat pump can provide the room’s requested mode when it differs from the central water loop.
Where the selected systems support it, PMS and room-status inputs can help coordinate comfort and energy settings with arrivals, departures, occupancy, and hotel operating priorities. Integration is confirmed during controls design.
Start with the property location, room count, existing equipment and controls, electrical information if available, representative photos or drawings, and your target schedule. A site visit may follow.
Property fit
Is your hotel a strong candidate?
The best starting point is not a product selection—it is a property-level qualification. These conditions often indicate that room-by-room modernization deserves a closer look.
See if your property qualifiesOccupied hotel
The property needs an improvement path that can work around room inventory and ongoing operations.
Existing two-pipe fan coils
Aging room terminals rely on a central loop that changes between hot and chilled water.
Seasonal comfort conflicts
Guests request cooling during heating season—or heat while the building is distributing chilled water.
PIP, renovation, or capital event
An upcoming project creates an opportunity to coordinate HVAC work with rooms already entering scope.
A desire to phase and preserve
Ownership wants to retain qualifying infrastructure and avoid defaulting to a disruptive, all-at-once replacement. Final feasibility still depends on loads, piping, water conditions, electrical capacity, controls, dimensions, and code requirements.
