Quiet - Efficient - Game Changer!
October 31, 2025Quiet - Efficient - Game Changer! We recently removed 2 fifteen year old propane fired furnaces and central A/C units. We upgraded to 2 electric heat pumps (much more efficient than propane). Our 5 ton Lennox and 2 ton Lennox units are performing flawlessly. I was amazed at the small footprints and the quiet operation. We hear almost nothing in the house and its even quiet at the outside fan units.
Yes, I recommend this product.
