If your boiler seems to be running but your radiators stay cold, either the system is not producing heat or that heat is not reaching the rooms. A lit display or humming motor does not always mean the burner has fired.
A boiler and a burner work together, but they do different jobs. In a fuel-fired heating system, the burner creates the heat by burning fuel, while the boiler uses that heat to warm water or produce steam that carries heat through the home.
New York City’s heat season begins October 1 and continues through May 31. Starting October 1, 2026, the NYC Department of Housing Preservation and Development will investigate every heat complaint as an individual case.
Some apartments in the same NYC building become too hot while others remain cold because the heating system is not distributing or controlling heat evenly. Common causes include poorly placed temperature sensors, unbalanced steam or hot-water systems, and differences in how individual apartments retain heat.
If you’ve paid for a commercial HVAC repair and the problem came back within weeks — or the same system keeps cycling through service calls — the repair probably wasn’t wrong.
Boiler tune-up costs in NYC vary depending on your system type, fuel source, and whether any parts need replacing during the visit. Oil-fired systems generally cost more to service than gas-fired ones. Steam boilers, which are common in NYC brownstones and pre-war buildings, typically involve more components than hot water systems.
Carbon monoxide detectors are important if your home uses oil heat. That does not mean oil heat is inherently unsafe or that oil-heated homes are somehow uniquely dangerous.
If your commercial HVAC system is still running, it can be tempting to keep repairing it and push replacement off for another season.
Sometimes that is the right call.
Sometimes it is the decision that ends up costing more.
