What Oyster Bay's winter means for your heat pump

In Oyster Bay, the average January low is -2°C (28°F), and the coldest temperature recorded from 2015-2024 was -19°C (-2°F). That's milder than 66% of the 123 cities we track. Winters here are mild enough that most cold-climate heat pumps can heat your whole home. Sizing and installation quality matter more than squeezing out extra cold-weather rating.

Before you hire a heat pump installer

  1. Ask for a room-by-room heat loss calculation. A quote that guesses the size from square footage alone is a red flag.
  2. Ask for the exact model and its heating output at your area's coldest temperature, not just the brand.
  3. Ask who handles the rebate paperwork and whether the model is on your rebate program's eligible list.
