Fall Tune Up Part 8 – Inside The Plenum

This system does have an air purifier on it. These cells have to be replaced about every two to three years. Even if they still visually appear to be working fine, the literature actually says replace them after about two years that they're not very effective. If you ever had a lizard of any kind, like a bearded dragon, then you know that you have the UV bulbs that you have to keep in their habitat. After a certain amount of time, they stop being productive and effective, even if they are still illuminating. There's a note here that this one was replaced last year in July. I have no reason to replace that. But what we do have here is a nice access into the plenum. So we'll be able to see if anything gross is going on inside of there. This thing is spotless. There's nothing in there at all. It's perfect.
