Six questions co-op boards, condo associations, and multifamily owners ask before a NYC Clean Heat conversion. If yours is not here, call (212) 810-0915. The dispatcher answers 24/7.
01What HVAC incentives do NYC multifamily buildings qualify for?
Multifamily buildings in NYC qualify for Con Edison Clean Heat prescriptive at $5,000 per dwelling unit on full-load ASHP with decommissioning, plus $1,000 per dwelling unit on heat pump domestic hot water, plus NYSERDA Heat Pump Program and Multifamily Performance Program custom incentives, plus NYS Clean Heat low-interest financing up to $25,000 residential. On a 24-unit building the rebate side is typically $144,000 to $250,000. The federal 25C and 25D residential tax credits expired December 31, 2025 and no longer apply. Vinco files the Clean Heat application as the participating contractor.
02How does the incentive stack differ for owner vs co-op vs condo?
Owner-occupied 1 to 4 unit buildings: owner files the Clean Heat application as the participating customer. Co-op buildings: the corporation is the customer of record. Condo buildings: similar to co-op for building-wide work. NYSERDA EmPower Plus is restricted to income-qualified 1 to 4 unit buildings and does not apply to co-ops or condos. The federal 25C and 25D residential tax credits expired December 31, 2025, so they no longer factor into the ownership split.
03What are the qualification thresholds for multifamily Clean Heat?
Building must be existing or a gut rehab, in the Con Edison service territory, 5+ dwelling units, with the primary heat source converting from fossil fuel to electric heat pump. Equipment must come from the NYS Clean Heat approved manufacturer list. Full prescriptive amount requires the fossil-fuel system be removed or permanently disabled; keeping it as backup pays a lower partial-load amount. New construction does not qualify (the one exception is geothermal in multifamily new construction). NYPA electric customers do not qualify. Mixed-use buildings file residential and commercial tracks separately.
04How long does the multifamily Clean Heat process take from application to rebate?
End-to-end runs 3 to 6 months on most multifamily projects, sometimes longer for full-building retrofits over 50 units. Sequence: site survey, engineered proposal, board approval (co-op or condo), Clean Heat application filed by Vinco, Con Edison pre-inspection, Notice to Proceed, NYC DOB permits, install (6 to 12 weeks on a 24-unit building), post-inspection, rebate netted against invoice. Larger buildings or projects requiring electrical service upgrades extend the install window.
05Can a NYC multifamily building stack Clean Heat with NYC C-PACE financing?
Yes. C-PACE financing covers up to 100 percent of qualifying multifamily HVAC and envelope work at fixed rates over 20 to 30 years. Survives ownership transfer, repaid through a property tax assessment. The Clean Heat rebate is netted against the invoice; C-PACE finances the residual after rebate. The combination lets a co-op or condo board cover the entire capital cost out-of-pocket-free while still claiming the incentive stack. Requires existing mortgage lender consent. Close typically runs 2 to 3 months.
06How does multifamily Clean Heat interact with Local Law 97 compliance?
LL97 caps building emissions for any NYC building over 25,000 sq ft. Multifamily co-op and condo buildings often fall 50 to 250 tons over the Period 2 cap (2030 to 2034) on a gas-boiler steam system. Converting to heat pumps with Clean Heat funding cuts emissions roughly 70 to 80 percent on space heating, which usually brings the building back under the cap. The Clean Heat rebate window aligns with LL97 Period 2 timing, which is why most NYC multifamily decarbonization is happening in 2026 to 2028 rather than waiting.
