Goodman Gsx13 - 4 Ton - Air Conditioner Oct 12, 2016

Very quiet, you can only hear the fan running. Suction line service valve is too close to the case makes it difficult to braze the suction line in.

Modine 30,000 Hot Dawg Heater Jul 27, 2016

Easy to install. Works great. Only drawback is not as quiet as expected but acceptable.

Great Unit Oct 23, 2016

Indoor Unit: Runs great. Easy to install. Almost silent at low speed and no louder than a 16" desk fan at high speed. Instructions are sparse but a DIY guy can figure them out with a little help from YouTube as well. Definitely get the outdoor cover track to make the installation look great. Easily keeps my 14x18x9 living room (east and south exposure) plus 12x12x9 kitchen plus 10x10x9 dining room cool on a 90 degree day with large window exposures on all walls. Outdoor Unit:more

Aprilaire Thermostat 8400 Series Dec 14, 2016

Its difficult to believe I am the first to review this product. However this thermostat is difficult to program and seams to defy reason, when in heat mode and should be using the compressor unit outside to produce heat, it instead will be making expensive heat with AUX electric heat. I will probably dump this thing and get one I can understand how to use effectively.
