All of you people are kidding yourselves when you say "janitrol is junk" I installed Carrier for 8 years and I now install Janitrol. Here are the facts--Janitrol doesn NOT advertise! Therefore the cost of their equipment is extremely less than all other brands! ALL parts are warrantied for 5 years and the heat exchanger is warrantied for life. No other company can match this warranty and all make you pay for warranty labor. For a minimal charge upon installation you can get labor coverage and extended parts for 10 years!! They have a simple design and upon proper installation will match any other brand out there. How else did they get to be the largest privately owned business in America? Oh, yeah, they also OWN Amana. Anyone heard of them?! Now go buy a Janitrol and save some money. Don't pay for the name!
