Building coordination
Coordinate service around occupied spaces and building rules
Property-focused HVAC requests need clear access instructions, affected areas, building requirements, and the person who can approve next steps.
- Building type, affected units or spaces, and site contact
- Tenant, customer, staff, or operations impact
- Access instructions, elevator or roof requirements, and COIs
- Photos, equipment location, and preferred communication path
If occupied spaces, operations, tenants, customers, or critical equipment are affected, call first so the request can be routed with the right urgency.
Building complaints
Tenant complaints and building comfort
A single apartment complaint, three units on the same line, and a building-wide no-heat call point to different possible failures. Airplex starts by finding the pattern: which units are affected, whether common areas are involved, what equipment serves the space, and whether the problem starts at the unit, distribution, controls, rooftop equipment, or central plant.
That pattern matters for owners, landlords, supers, and building managers because it decides where the mechanical investigation starts and how quickly the building needs help.
One line or stack
Several complaints in the same line can suggest a pattern beyond one resident. Tell Airplex which apartments are affected, whether the issue repeats, and what changed recently.
Whole building
Building-wide no heat, no cooling, weak heat, or repeated outages point toward central equipment, distribution, controls, rooftop equipment, or broader maintenance needs.
Common areas
Lobbies, hallways, amenity spaces, stairwells, basements, boiler rooms, and mechanical rooms need clear access details and an on-site contact who can meet the technician.
Mechanical service
Repair, maintenance, and replacements
Airplex handles multifamily HVAC repair, maintenance, replacement planning, heating repair, AC repair, boiler and furnace service within verified HVAC scope, RTUs, VRF/VRV, heat pumps, mini-splits, thermostats, controls, and refrigerant concerns when they are part of the mechanical system serving the building.
For managed portfolios or ongoing vendor coordination across many buildings, use Property Manager HVAC. For a single resident or owner-occupant unit, use Apartment & Condo HVAC.
Multifamily HVAC repair
Airplex repairs HVAC problems affecting occupied units, common areas, central systems, rooftop equipment, and building comfort. For unclear symptoms, start with repair diagnostics.
HVAC RepairHeating repair
No heat, weak heat, uneven heat, boiler trouble, furnace issues, or controls that are not responding can be reviewed through heating repair or emergency HVAC when occupied spaces are affected.
Heating RepairAC repair
No cooling, warm air, weak airflow, water around equipment, frozen equipment, or repeat cooling failures can be reviewed through AC Repair or HVAC Repair.
AC RepairMaintenance
Maintenance helps owners and supers get ahead of repeated winter complaints, seasonal startup problems, airflow issues, control concerns, and aging equipment.
HVAC MaintenanceReplacement planning
If central equipment, rooftop units, or other building HVAC keeps failing, Airplex can review replacement planning without turning the page into design or engineering advice.
HVAC ReplacementInstallation planning
For planned heating, cooling, RTU, VRF/VRV, heat-pump, mini-split, boiler, or furnace work, Airplex can review property fit, equipment, access, and building requirements.
HVAC InstallationWinter readiness
Heating season readiness
Heating season readiness is easier before tenants start calling. Airplex can review maintenance needs around boilers, heating equipment, controls, distribution symptoms, rooftop equipment, filters, airflow, and repeated complaints before winter pressure exposes weak points.
Occupied-unit no-heat calls need priority handling as a process matter. Airplex can review the mechanical issue, access path, affected units, and equipment condition without giving tenant-law, HPD, DOB, or code advice.
Before winter
Review heating equipment, recurring tenant complaints, controls, pumps, filters, airflow, and service history before the season exposes a weak system.
HVAC MaintenanceRepeated complaints
If the same units complain every winter, the pattern matters. Airplex can compare affected units, floors, equipment, controls, access, and prior repairs.
HVAC RepairRepair or replace
Aging central equipment, repeated failures, and hard-to-keep-running systems may need replacement planning instead of another temporary repair.
HVAC ReplacementEmergency no heat
No heat or no cooling in occupied units is an operational problem for owners, landlords, supers, and building managers. If occupied units, vulnerable people, common areas, operations, or temperature-sensitive spaces are affected now, call Airplex or use Emergency HVAC.
Emergency HVACBuilding systems
Central equipment and distribution
Multifamily buildings may involve central boilers, furnaces, rooftop units, VRF/VRV systems, heat pumps, mini-splits, thermostats, controls, refrigerant diagnostics, occupied units, common areas, roof equipment, basements, boiler rooms, mechanical rooms, and outdoor equipment. The building type, access, and complaint pattern matter.
Airplex looks at the mechanical system and the building reality: where the equipment is, who can open the space, how tenants are affected, and whether the complaint pattern points to repair, maintenance, or replacement planning.
Boilers and furnaces
Airplex services, repairs, and installs furnaces, high-efficiency water boilers, low-efficiency water boilers, tankless boilers, and water heaters within verified mechanical/HVAC scope.
Boiler RepairRTUs and rooftops
Rooftop equipment serving units or common areas needs clear roof access, building contact details, and safe equipment photos when available.
Rooftop Unit ServiceVRF / VRV systems
VRF/VRV issues can affect one zone, multiple units, or shared spaces. Airplex handles service and planning when the system and property are a fit.
VRF / VRV ServiceControls and thermostats
Schedules, sensors, zoning, thermostats, and control problems can create recurring complaints even when equipment is running.
Thermostat & ControlsHeat pumps and mini-splits
Heat pumps and mini-splits can serve units, additions, common spaces, or supplemental comfort needs when the building and system requirements work.
Heat Pump RepairRefrigerant concerns
Cooling symptoms that suggest refrigerant-side problems need a qualified HVAC technician. Do not try refrigerant work yourself.
Refrigerant DiagnosticsVisit planning
Access, supers, and COIs
Walk-ups, elevator buildings, mixed-use buildings, and larger apartment properties need different access planning. Share the super contact, building-staff contact, unit access windows, roof or boiler-room access, work-hour limits, COI requirements, and safe photos before the visit when available.
Clear building coordination helps prevent wasted visits: confirm who can open the boiler room, roof, mechanical room, basement, common area, or apartment before requesting service.
Super contact
Share the superintendent or building-staff contact who can provide entry, show equipment, open mechanical rooms, and confirm affected units or common areas.
Unit access
Tell Airplex which apartments need access, whether residents are available, and whether the issue affects one unit, several units, a line, or the building.
COIs available
Airplex can provide COIs for applicable commercial or building-managed HVAC work. Share any requested wording from management when you contact Airplex.
Photos help
Safe photos of equipment, nameplates, thermostats, error codes, boiler rooms, roof units, mechanical rooms, and affected spaces can help Airplex prepare.

FAQ
Multifamily HVAC FAQs
Does Airplex provide multifamily HVAC service in NYC?
Yes. Airplex repairs, maintains, and helps plan replacement for HVAC systems serving multifamily buildings, apartment buildings, occupied units, common areas, boilers, rooftop equipment, and central systems in NYC and Northern New Jersey.
Three tenants on one line have no heat. Is that the boiler or the riser?
It could be a local, distribution, control, or central equipment issue. Airplex starts by reviewing which units are affected, whether the issue follows a line or stack, and what equipment serves those apartments.
Can you service both units and common areas?
Yes. Airplex can work on HVAC serving occupied units, common areas, mechanical rooms, boiler rooms, rooftops, and outdoor equipment when access and system scope are a fit.
Tenants complain every winter. Can maintenance get ahead of it?
Maintenance can help identify weak airflow, dirty equipment, control issues, boiler or heating concerns, and recurring patterns before the busiest part of heating season. Share prior complaint history if you have it.
What if there is no heat in occupied units?
If no heat affects occupied units, vulnerable people, common areas, operations, or temperature-sensitive spaces, call Airplex or use Emergency HVAC. Airplex can review the mechanical problem without providing legal, HPD, tenant, landlord, or code advice.
Do you repair multifamily AC and cooling systems?
Yes. Airplex repairs multifamily cooling problems, including no cooling, warm air, weak airflow, rooftop equipment issues, VRF/VRV concerns, controls, and refrigerant-side symptoms within HVAC scope.

Use Apartment & Condo HVAC for a single-unit resident, apartment owner, condo owner, or unit-specific comfort issue. Multifamily HVAC is for building owners, landlords, supers, and building-level or multiple-unit concerns.
How much does multifamily HVAC service cost?
Contact Airplex for a current estimate. Pricing depends on the building, system, symptoms, equipment location, access, urgency, and property requirements.
What should I have ready before requesting service?
Have the building address, borough, your role, units or common areas affected, system type if known, no-heat or no-cooling status, super or building-staff contact, access windows, COI needs, and safe photos ready.
