Multi-Family HVAC Service in Yonkers — Owner's Guide
Two-family, three-family, and small apartment building HVAC in Yonkers — separate metering, tenant maintenance lines, and what to spec on replacement.
Published 2025-12-22 · Bravo Mechanical, Westchester County, NY
Yonkers has more two- and three-family homes than any other Westchester city. If you own one, HVAC decisions affect tenant comfort, vacancy rates, and your operating costs in ways single-family owners never deal with.
Common Yonkers multi-family HVAC setups
Single boiler, multiple radiators
The 1920s–1940s standard. One boiler heats both/all units, owner pays for fuel, often included in rent. Tenants control heat with TRVs (thermostatic radiator valves) or just radiator handles.
Per-unit furnaces
Each apartment has its own furnace and ductwork. Tenant pays gas bill. Owner responsible for equipment.
Per-unit boilers
Each unit has its own boiler. Less common in Yonkers but increasing in renovations.
Through-the-wall PTAC
Old apartment-style cooling. Each unit has its own. Cheap to replace but loud.
Mini-split per apartment
Modern conversion choice. Owner installs, tenant operates.
Owner pain points and solutions
"Tenants run the heat to 80°F"
Switch from owner-paid to per-unit gas service if possible. Otherwise install central control with TRVs and a building thermostat with weather compensation. Cuts overheating by 25–40%.
"I get no-heat calls every winter"
Two solutions: 1. Schedule annual fall tune-ups for every unit (deductible expense) 2. Replace 20+ year old equipment proactively, not reactively
"AC season kills me"
- One outdoor unit serves up to 8 indoor heads
- Each tenant gets independent control
- Heat pump qualifies for NYS Clean Heat rebates ($5,000–$10,000+ for a 2–3 family)
- Eliminates window AC liability
