  1. I have an apparent Amana central air unit with the furnace, evaporator coil box and a condenser which is on the rooftop. The air conditioner Stopped cooling very well but it was still working. The repair person came and told me that there is oil leaking from the condenser, while the other person said that there should be no oil in there I'm very confused

  2. Great video explaining how an ac works! Great way to become familiar with all the components and their functions. Thank you.

  3. I have a Lennox G40UH(X) Furnace that has a bad combustion air inducer. does this Co have one that fits my furnace?
