Hunting For The Wrong Problem - 2nd Try…I Just Had to Go Back to Basics

Guys, in the video I'm going to put together for you today, it was a real head scratcher. What the homeowners were telling me caused me to look everywhere except where the problem was. A lot of times, if you listen to the homeowners, they can pretty much tell you what the problem is. But this time, they caused me to chase my tail. So no, I'm not going to tell you what it is. You're going to have to watch. Here it comes. all right in this one i had to come so far out in the country i did not even know what county i was in this is mitchell county down in south georgia which is basically like two counties away and one side of the house is really hot that is nice and cold i think we need to make a trip under the house look what was in here that could have shortened to the cabinet how about this this customer is letting me drive right up to the air conditioner I just have to stay away from the septic tank right now we're I'm just gonna park right in front of this access so we can go under the house here's my air handler under there and as far as crawl spaces go this one ain't bad at all I gotta put on some gloves to keep from putting my hands down in the dirt she said the house one side of the house where the thermostat is stays hot and it was 81 degrees in there it looks like we're gonna have two branches i just want to look at things first and i see my return there let's walk around and take a look at the other side all right getting to where a damper might be let's see just by design i don't see where they would have difficulty on this side of the house it's a possibility that some well that box is insulated on the outside i got no idea how much of that is usable by the way i do pull up my mask when i'm down in places like this fantastic all right let's see if we can find a way to get a peek at this coil what i see on that coil is it's clean i've seen y'all have now seen more of that that coil than i can see but it looked clean i don't see nothing in the return something else has got to be going on let's see oh my there's still a screw in it all right i'm not seeing anything obvious down here that's not enough to cause our problem no dampers all right let's go back out and check pressures we got us a 2007 r22 unit here two and a half tons temperature is close to freezing 272 62 that head pressure is a little high considering how low the suction is what do you want to bet if i wash this coil out that pressure is going to drop and it's going to clearly be low on freon there's one way to find out all right that coal was not dirty let's go in and start checking the register she is not correct when i went around and checked the airflow the airflow on this side of the house was clearly poor and um i did put the old thermostat back on the wall but i'm afraid it may have been icing up the temperature of the suction line relative to how hot it was in there and those pressures i think that suction line should have been warm i'm gonna check my probes but that's my supply and that's my return this was in the hottest room in the house but this may require a trip underneath it is running in cool maybe i can get a better picture of that coil to see if there is any ice on it well we are back down here these gloves when i'm crawling around let's see if i missed something seeing any ice if i leave that panel off long enough i will that's it that's in the hottest room in the house and it's hotter in there than it is at the return dang it i didn't bring my my meter the wheel lights up put this panel off see to try to see which one is pulling possible i do want to know which one is pulling we can disconnect it the way this is set up it's easier to replace the whole heater kit so i know it's that way and the bottom down there well it wasn't just hot in that room the heat was on you just see the difference in my return and my supply that was in the hottest room with the least air flow pressures are still normal I only figured it out I was chasing my tail because once I had the house was hot the other side was cool there was less air flow that I could feel you know thought maybe it was freezing up but it was the heat strip and between you and me those are the kind of calls that I like because it's like an investigation when you find it it's a it's a satisfying feeling Thanks for watching, and I'll catch you on the next one.
