Helpful Gadgets: An Air Flow Meter

A cool gadget that I like to take with me when I go Rving, is an airflow meter. This will tell me two things. It'll tell me the air flow coming out of my air conditioner or my furnace. And it'll also tell me the temperature. You know, if I just tell somebody that I don't think my air flow is coming out enough, my air conditioner isn't cool enough. That's a little too general. So, what I want to do is just, periodically test the air flow coming out of it, test the temperature. If I see it start to decrease, then I know I probably am gonna have to change my filter inside my air conditioner, or if I see the temperature going, you know, up and it's not cooling quite as well as it was before, then I'm gonna have to take it in to my dealership and probably have it recharged. So it's really easy to do, you just simply turn this on here. I'm gonna turn the air conditioner here and we've got air flow on the front side here, also on the backside. So I'm just gonna take this, put it up there. So now I'm gonna change my settings. And we're gonna get to temperature. I see I'm running at 67.6. Now, one of the things I did notice with this, is I have a little less airflow than I've had in the past. So that's kind of telling me that my filter up here is probably plugged, very easy to change. Two screws. Take my knobs off the front. And we see we've got some filters that start to look like they need to be changed. Now I can use the same air flow meter on the furnace so I can get air flow out of that and temperature. So it's a good idea to know exactly what temperature, what air flow is coming through it, rather than just have the generality of saying, I don't think my air conditioner's cooling is efficient.
