Lennox Air Handler
July 31, 2025This air handler is a little larger than the last I had which made installation more difficult. Seems to handle circulation of cool air well but notice a little more humidity stays in house with this unit. Located in NH, glad it’s not hot and humid year round. This was a replacement for a 16 year old York system. I’ve only had it for less than a month. A second request for review in September would tell us both more.
