ML17XP1 Heat Pump
Lennox the heat pump that has kept us cool.
August 26, 2025We have had the Lennox heat pump and air handler installed after or old unit was found to be unrepairable, although it has only been two summer months now we so far are pleased with both units. Winter will be the here soon and we expect there will be a huge improvement with the comfort level as there has been during the past two summer months here in Kansas.

Yes, I recommend this product.
