Demands for efficiency pay off for tenants in Brooklyn’s Crown Heights in the form of brand-new heat pumps
For years, tenants at 792 Sterling Pl., an 82-unit rent-stabilized building in Brooklyn’s Crown Heights, endured freezing winters due to inadequate heating. “The heaters were completely useless; at times, I’d use my oven to try and heat the apartment,” said Chase Dimura, who rents a studio in the five-story building. Building owners Safdie Realty had installed wall-mounted electric fan units that were very expensive to run and frequently failed to maintain even legal indoor temperatures, let alone adjust to residents’ comfort. “The apartment would be in the mid-50s Fahrenheit at times,” Dimura said.
At 792 Sterling Pl., tenants resorted to buying space heaters. The combined cost of inefficient fan heating and additional electric radiators pushed some residents’ monthly energy bills to more than $900.

When Anna Nemetz moved into a one-bedroom at the building in early 2023, she was shocked to get an electricity bill for $376. “It wasn’t even the full month, and I was already feeling pressure financially,” she said. Even though New York City landlords are required to provide heat, in some newer buildings like this one, which was built in 2007, payment for the utility falls on tenants. “That whole first winter I felt very isolated and almost ashamed,” Nemetz said. Even though she raised issues with the building’s management, JSAF Property Management, her drafty windows and fan heaters kept her energy use high.
The Challenge
New York apartments must be heated to 68°F during the day and 62°F at night during what’s called “heat season” — between October 1 and May 31, when the outdoor temperature is below 55°F. If they aren’t, a landlord can face legal action in housing court.
At 792 Sterling Pl., there’s a long history of housing court action over heat and hot water, going back to 2011. Housing Preservation and Development (HPD), which oversees building conditions, has initiated multiple cases over the years in response to unresolved heat and hot water violations. In general, fines for a lack of heat start at $350, and can quickly reach $1,500 per day for repeated offenses. By the middle of 2024, the building had so many violations and heat complaints that it was enrolled in a HPD heat sensor program to closely monitor conditions. In the past two years, litigation against the building’s landlord has resulted in fines of $68,550 for a lack of heat and hot water.
In addition to baseline heating requirements, many landlords citywide are considering electric alternatives to oil and natural gas in an effort to meet carbon emission caps and avoid fines under Local Law 97 (LL97). Buildings with more than 35 percent rent-stabilized units, like 792 Sterling Pl., have some flexibility in meeting LL97’s carbon emission targets, but must still implement energy conservation measures. However, since the heating system at this Crown Heights rental is electric, the landlord is technically already in compliance with the law — without a gas or oil-fired boiler, the building is considered emission-free. Even though the existing heat system is inefficient, the landlord is not facing LL97 penalties.
According to city data, a 10-percent reduction in electricity use at the building would generate $10,333 in savings. Yet these savings wouldn’t benefit the landlord — rather, they would help out the individual tenants who pay the utility bills. So, with little incentive for management to upgrade to a better system, how could tenants get their landlord to fix their inefficient, ineffective, and expensive heating?
The Roadmap
Collective action has long been a strategy for rent-stabilized tenants to get landlords to meet their obligations. In March 2023, tenants at 792 Sterling Pl. began talking to each other about conditions in their apartments. Nemetz helped migrate a largely inactive Facebook group to Whatsapp, and encouraged residents to join. The group ultimately attracted over seventy tenants. “It was building solidarity, building community, and the purpose was to talk about issues in the building, the main one being a lack of legal heat,” Nemetz said.
From her window on the third floor, Nemetz could see HVAC equipment on the roofs of neighboring buildings — condensers for a heat pump system. Nemetz wondered if this could be an alternative heating solution to present to the landlord. After some research, the newly re-formed tenant group concluded ductless mini split heat pumps were the answer to their heat problem. “A lot of us had been in other apartments where we had these split units and it was fine,” Nemetz said. “It’s a little bit expensive, but nowhere near what people were paying [at 792 Sterling Pl.].”
As temperatures dropped again in late 2023, landlord inaction over the heat pushed the tenant organizers to escalate their efforts. They held a building-wide call-in day to 311, the city’s complaints hotline. Calls to 311 can lead to building violations, adding to fines for the landlord. Over the past two years 198 complaints have been made about the building; 132 are related to a lack of heat. The tenants also contacted their City Council and state representatives. They sought advice from non-profit legal clinics, getting tips on negotiating with the landlord and information about their rights.
In the right circumstances and with the right preparation, withholding rent can be used as a tactic to get a landlord to make repairs. Having spelled out the heat problems to the landlord, via HPD and in written communications, this was the tenants’ next move. At least a dozen residents withheld a portion of their rent, “between $500 to $700 for each apartment,” Nemetz said. In most cases this was the cost of their monthly heating bills. The decision to go on partial rent strike wasn’t taken lightly. “It’s very scary to withhold rent. People were really afraid, myself included,” Nemetz added.
Withholding rent raises the risk of a landlord filing an eviction case in housing court for non-payment. “If a tenant is sued for withholding rent, they may raise the lack of services as a defense in the proceeding and seek an abatement from the court,” said Magda Rosa-Rios, director of housing group advocacy at The Legal Aid Society. A rent abatement can either be negotiated with the landlord or may be ordered by a court. But for tenants, the prospect of litigation can be daunting; it’s often an unmatched fight, even if your case is strong.
The landlord and building management acknowledged the tenant’s concerns, but it didn’t result in any meaningful changes. (Neither party responded to multiple requests for comment for this article.) From the tenants’ perspective, collective action got results. Within six weeks of the partial rent strike, the property manager agreed to a meeting where residents again asked for heat pumps to replace the fan heaters. Management used the meeting to push for an end to the rent strike, but Nemetz said this was something their group would not commit to without a timeline for upgrades. Soon enough, heat season was over, and there was still no lasting or building-wide solution.
Even so, as winter rolled around again in 2024, tenant organisers were hopeful. “The only time we ever heard a whisper of a plan was when we withheld rent,” Nemetz said, so they decided to commit to it again. This time the 15 or so tenants involved in the rent strike withheld their full rent. Within a few months they achieved a major victory. JSAF Management was replaced by Elite Management, and by early January 2025, plans had been filed with the Department of Buildings to replace the expensive fan heaters with high-efficiency heat pumps to provide both heating and cooling.
The Project
The heat pump installation began by late January. “It was amazing how quickly they jumped into action,” Nemetz said. Even so, the rollout was far from smooth. One of the challenges with mini split units is the need to run refrigerant lines throughout the building to connect to rooftop condensers. This added to the disruption for residents, who had to provide workers access to their apartments. “It was super invasive,” Nemetz said. Tarps were needed to protect personal belongings. The drilling was noisy. There were holes in the walls. The work created dust that wasn’t always cleaned up. Yet after what Dimura called a “grueling” few weeks, the installation was complete and the units were functional.
Nemetz was charged $144 for electricity the following month. “I was hoping it would be lower, but I feel great about it,” she said. Other tenants saw a decrease of up to 60 percent in their utility bills. The mini splits deliver both heating and cooling, and since heat pumps are generally more efficient than window AC units, the tenants are hopeful electricity costs will decrease year-round. “The cost of electricity is instantly less,” Dimura said.

According to city data, the estimated cost of installing the mini splits at 792 Sterling Pl. was $406,500, translating to roughly $4950 per unit. Incentives are available for these types of projects, and it’s likely the landlord took advantage of financial help provided by Con Edison’s Multifamily Clean Heat program. “Buildings using gas, oil, or non-heat pump electric heating are all eligible,” said Elisabeth Ferrari, media relations manager at Con Edison, adding that LL97 implications are not a factor in the eligibility screening for financial incentives.
Although the efficiency savings will be enjoyed by the tenants, there are benefits for the landlord as well. At the very least, costly fines and rent strikes for lack of heat should now be eliminated. The landlord hasn’t shared the precise reason behind the decision to install heat pumps; It may have been the coordinated tenant action, a persuasive new property management company wanting to end rent strikes, financial incentives bringing down the cost of heat pump installations, or even just common sense around energy efficiency. Perhaps it was all of these. In any case, Nemetz is glad for the change, and is looking forward to warmer winters.
