Built for the winters that freeze coils.
Crosswind looks after heating, cooling and ventilation for offices, schools, warehouses and older buildings across the Capital Region — with a fall routine that keeps coils from splitting in January. Homes too.
- Outside-air dampers close fully.
- Freezestats trip, and the unit responds.
- Heating coils flow; glycol is strong enough.
- Cooling coils drained or protected.
- Rooftop heat sections fire cleanly.
Capital Region buildings, old and new.
Offices off Wolf Road and the Northway, schools, warehouses along I-87 and I-90, and older downtown buildings still heated by steam and hot water.
- Air handlers with hot-water, steam and chilled-water coils.
- Rooftop units, split systems and unit heaters.
- Controls, freezestats and dampers that behave in January.
Six freeze points, checked every fall.
Most winter coil failures start in one of six places inside an air handler: the outside-air damper, the mixing box, the heating coil, the cooling coil, the freezestat and the condensate trap. We check all six before the first hard freeze.
And the house you go home to.
Furnaces, heat pumps and air conditioners in Albany, Colonie, Guilderland and Bethlehem houses — repaired, tuned up and replaced by the same technicians, with the cold-weather weak points checked.

What facility managers ask in October.
Why do air handler coils freeze in winter?
Usually because sub-freezing outside air reaches a coil that still holds water: a damper sticks open, air does not mix, hot water stops flowing, or a cooling coil was not drained. A working freezestat should shut the unit down first, which is why it is tested every fall.
What is a freezestat?
A low-limit sensor stretched across the face of a coil. When the air there gets close to freezing, it stops the fan and closes the outside-air damper to protect the coil.
Do you work on steam and hot-water heating?
Yes, on the heating coils, valves, traps and pumps that serve air handlers, alongside rooftop units, split systems and controls. Boiler repairs themselves are handled with a boiler specialist where needed.
Do you work on homes?
Yes. Commercial work leads, but we repair, maintain and replace furnaces, heat pumps and air conditioners in houses across Albany, Colonie, Guilderland and Bethlehem.
Is New York licensing required for HVAC contractors?
New York State does not issue a general HVAC contractor licence. Some cities and counties license or register contractors, and mechanical permits are issued locally.
