Expert Cooling & Heating Solutions for Every Space

NYC heat season runs October 1 through May 31, and a cold apartment now turns into a 311 heat complaint within hours. What the law requires, an eight-point boiler checklist for supers and property managers, what the work costs, and how to tell when a boiler is past repairing.

Mitsubishi, Daikin and Fujitsu all make equipment that outlasts the apartment it goes into. The real differences are narrower than the brochures suggest — cold-weather behavior, how low a unit can throttle, what fits a pre-war wall, who has the part in ten years. How a technician actually chooses.

Most comfort complaints in a ducted building are distribution problems, not equipment problems — and the equipment gets replaced anyway because nobody looked inside the ducts. What a proper inspection finds, what it costs in NYC, and how often you actually need one.

The federal heat pump tax credit expired at the end of 2025, which changed the arithmetic but not the answer: in Con Edison territory the utility money is now the money, and it is several times larger than the credit that went away. Here are the 2026 numbers, who qualifies for which program, and the details that decide what actually lands on your invoice.

A box drifting up two degrees an hour is a different problem from one sitting at 55°F, and the fix is usually cheaper than the panic suggests.

Cold air from the vents in heating mode is sometimes a five-second fix and sometimes a safety lockout you should not reset twice. Here is how to tell which one you have — fan settings, clogged filters, ignition faults and heat-pump defrost, in the order a technician checks them.
