Heat Pumps 101: Just how noisy is a heat pump, really?
Short answer: not very! Most heat pumps today use inverter technology, letting the fan adjust anywhere from 20% up to full speed instead of just blasting on and off. That means they can run a lot quieter than you'd expect.
Sound levels vary by brand, features, and sizing, but generally, outdoor units run around 50-55 decibels, while indoor units can be as quiet as 20 decibels. About the same as light traffic outside, a fan humming in another room, or your fridge running in the kitchen.
So if noise has been holding you back from making the switch, it might be time to reconsider! Questions about your setup?
