  • Senville 3 Ton Priced Right. Works Right!
Size: 3 TON / 20 KW AUX
Senville has an amazing product. This unit is not a DIY setup. With that said it can be if you are handy. The warranty will go out the window if you DIY but chances are a failure is slim to none. These units tend to run all day unless you program them for a turn on and turn off time. It is not a flaw in the design but an evolution of HVAC technology. The 3 ton unit adjusts it's output relative to the demand it faces. So yes while it runs all day I doesn't face the hard start and stops my previous gen Mr Cool unit does which requires more energy and this raises the electric bill. The thermostat is a 2 wire AB set up and the remote comes in handy. The condenser communicates with the AHU via S1 S2. The AHU can be programmed to adjust to duct work size as well. It is really intuitive. Be aware if you run an Aux Electrical Heating element there will be quite a few breakers. I needed a 30 Amp for the condenser, 15 or 20 Amp for the AHU, and a 60 for the 10 KW AUX element if you go larger then you need two 60 AMP Breakers. I am still learning the operational side of this but from a performance side. It runs, it cools, and it is exceptionally quiet. It all comes with a lowered electrical bill to boot. The day I turned it on the temp went from 86 degrees in the house to 74 in about 2 hours which was impressive. When it comes to heating we will see how winter is this year. Senville for the win. ... show more
