Corona’s Multi-Unit Buildings Face a Hidden Crisis: When Shared Boilers Create Heating Havoc and Neighbor Wars

In Corona, Queens, a growing number of apartment dwellers are discovering that sharing a boiler system isn’t just about splitting utility costs—it’s becoming a source of serious heating inequities and heated disputes between neighbors. As winter temperatures plunge, landlords and apartment building managers are finding that few things impact tenant satisfaction (and their bottom line) more directly than the building’s heating system, and when the boiler system falters, it can quickly lead to tenant complaints, legal issues, and expensive emergency repairs.

The Shared Boiler Problem: When One Size Doesn’t Fit All

The fundamental issue plaguing Corona’s multi-unit buildings lies in how shared boiler systems distribute heat. Many older buildings have no zoning and no good way to zone from the basement since various apartments and floors are tied into the same pipes, resulting in cold apartments on the 1st floor and hot on 2nd/3rd floors which leads to tenant complaints and upstairs tenants leaving windows open to regulate their heat.

This heating inequality isn’t just uncomfortable—it’s costly. Water heating accounts for a fifth of the energy used in apartment buildings, with total heating system efficiency hovering around 50%, meaning that only half of the energy purchased ends up as hot water at the tap. When some units are overheating while others freeze, the system works overtime, driving up costs for everyone.

The Technical Culprits Behind Heating Disputes

Common causes of uneven heating include trapped air in radiators or pipes, faulty zone valves, circulator pump issues, or a boiler operating below set pressure—all of which can cause inconsistent heat distribution. In Corona’s aging housing stock, these problems are particularly prevalent.

Many residents report scenarios where thermostats are set to 70°F, but actual room temperatures reach 83°F, and even replacing the thermostat doesn’t resolve the overheating issue. Meanwhile, neighbors in the same building may be bundling up in winter coats indoors.

The power wires on circulators might have been switched, which could mean your thermostat is now controlling heat in another unit while theirs controls heat in yours, or a faulty or poorly located thermostat may misread room temperature.

When Repair Bills Become Battlegrounds

The financial disputes surrounding shared boiler repairs are escalating in 2025. Property managers are noticing spikes in heating bills compared to previous years, despite similar weather conditions, which can point to a loss of system efficiency due to aging boilers, scale buildup on heat exchangers, malfunctioning thermostats or controls, or boiler short-cycling.

When major repairs are needed, determining who pays becomes contentious. Visible water pooling near the boiler or stains on nearby floors usually signals a leak, and even small leaks can lead to significant damage over time, affecting flooring, insulation, and structural components—in cases where the heat exchanger is cracked, a full boiler replacement may be necessary.

The Corona-Specific Challenge

Corona’s infrastructure, shaped by early 20th-century construction, often includes aging cast iron or clay sewer lines susceptible to blockages, corrosion, or root intrusion, and the neighborhood’s low-lying terrain and combined sewer system make it prone to flooding during heavy rains. These conditions compound boiler problems, as Corona’s cold winters rely on dependable boilers, often gas or oil-powered in older homes, but age impacts performance with aging boilers raising costs through uneven heating.

Solutions That Actually Work

Forward-thinking property managers are implementing modern solutions to address these age-old problems. Installing thermostatic radiator valves in each apartment, together with a coordinated thermostat, lets tenants have their desired amount of warmth in each room of the apartment, reducing complaints of overheating or not enough heat while helping eliminate wasted energy because they can lower the heat in rooms not being used regularly.

For buildings requiring major overhauls, some seven-unit apartment buildings are replacing central steam boiler systems controlled by a single thermostat with individual heat pumps for each unit, eliminating the inefficiencies and tenant dissatisfaction caused by a centralized boiler.

When to Call the Professionals

Corona residents experiencing persistent heating issues shouldn’t wait until the system fails completely. Property owners should have their maintenance team or an HVAC professional check for air in the system, inspect zone valves, and test the pump, as malfunctioning valves in larger buildings with multiple heating zones are a frequent culprit and may need to be replaced or reprogrammed.

Looking Ahead: The 2025 Heating Landscape

As Corona’s apartment buildings age, the shared boiler crisis will likely intensify without proactive intervention. Understanding the early warning signs of boiler trouble can help address issues proactively, avoid system failures, and extend the life of equipment. Property managers and tenants who work together to implement modern heating solutions today will avoid the costly disputes and emergency repairs that plague buildings still operating with outdated, inadequate systems.

The key is recognizing that shared doesn’t have to mean unfair. With proper zoning, modern controls, and professional maintenance, Corona’s multi-unit buildings can provide comfortable, efficient heating for all residents—without the neighbor wars.
