Con Edison has the highest incentives for heat pumps of any utility under the NYS Clean Heat program and has seen rapid adoption by single-family homeowners but large multifamily and commercial customers have been slow to adopt. Large projects have increased complexity and do not benefit from economies of scale so installation costs remain high. Multifamily & commercial building owners that make the investment don't receive the benefits of the upgrades, generally reserve capital expenditure for core business or emergency purchases and either may not have access to proper capital funding or cannot spare time to secure scarce traditional debt. Non-profits, particularly houses of worship, may be ineligible for potential tax credits for technologies well suited to their building type. Heat as a Service overcomes the financing gap not solved by traditional loans needed for large customers to undertake heat pump projects. These customers have the capabilities to keep current inefficient fossil heating equipment operating well beyond useful life so they are among the largest emitters and any like-for-life replacement will still be in-service past dates necessary to curb climate change and the devastating effects that will impact NYC earlier than most.
