Hello,

I just closed on the purchase of a 4-storey condo townhouse. Each floor has its own climate control, in the form a heat pump built into the wall.

I am in Canada and the units are currently operating in the heat cycle. Every 2 hours or so, they seem to kick it with a "sputter", and wheeze through the next 30 minutes, and then quiet down.

This is not so bad during the day, but at nights, they are keeping everyone awake as there is one on every floor. There is no getting away from one as each floor only measures around 500 sq. foot.

This is our first experience with heat pumps, and I am not sure whether we got faulty units, or if this is part of the package. Is there any way to lessen (if not eliminate) the sound? Currently they are built into the walls, with a hinged metal door that leaves a 1/2 inch gap all around. Does the noise get getting in the cooling cycle?

Thanks in advance for your help.
