Measuring A/C Air Temp
Hi,
I'm having problems with my A/C. I'd like to measure the air temp. coming out of the ceiling vents. I've read that most infrared guns only read surface temps. I've had A?C repairmen over, and they look like they are using an infrared gun. What can I buy to accurately measure the air temp from the vents? TIA |

But, if they are using an IR gun they are probably measuring the temperature of the vent metal which should reflect the air temperature pretty well.

Checking the vents helps, bur checking temp drop over the evap coil is good too. |

It depends on what you're buying at HF and what your usage is. I recently bought a 3/4" breaker bar, for example. From what I can see, it appears close enough to Craftsman or SnapOn so for what I'm using it for, it's a good deal. Usage is to loosen up wheel hub nuts on a car, something I might do once a decade. I also bought a set of impact sockets, and a set of extensions and they work perfectly fine. On the other hand, if I needed an electric saw to use in trades, I don't think I'd buy it at HF. And for something like a multimeter, I agree buying a Fluke is the way to go. My current one is 30 years old. I bought a cheap one at HF to leave on my boat. It worked OK at first, within a year, it was reading 30% off. I also needed some snap ring pliers, bought a set at HF. The tips, instead of being hardened steel, were so soft that they just bent. But I took them back and they gave me a full refund. So, I'd say it depends on what you're buying, your usage, and using some judgement. |

Carried in a shirt pocket. A friend of mine was a mystery shopper, and often did shops at Starbucks. The company she worked for sent her one of the little thermometers, with the 2 or 3 mm probe, and the plastic probe cover. She would buy coffee and a baked good and leave, go just out of sight and measure the temp of the coffee. I think they didnt' tell her what the temp should be, for fear that would bias her answer. I think it couldn't be too cold or too hot. When I was there, I would eat the baked good. (She's 50 and still weighs what she did in the 7th grade.) When she stoppped working for them, I think they wanted the thermometer back, or maybe it was just the stopwatch they gave her for another client. A lot of her clients went out of business within a year after she was hired. Mystery shopping was their last ditch effort to find out what they were doing wrong. But Starbucks is still going strong. |

I use IR gun In the US, we have to register our IR guns, and cannot legally use them in public places or federal or state buildings. I repair roll laminators for a living, I carry a one of those harbor freight ones, a customer went nuts, stating you cant have a gun in a sschool. i pointed it at my arm and the laser light came on and the customer went nuts till she saw the temperature read out. she believed it was a real gun........_ |

I use one from Pep Boys that they sell to measure the temp of the A/C ducts in a car. It has a 6 inch probe with a round dial attached to the end of the probe. That was pretty much standard equipment for all AC technicians at one time and they still work fine. I went a step further and drilled tight-fitting holes in my return-air duct and supply plenum at the furnace and permanently installed one of these thermometers in each. That way I can, with a glance, see both temperatures and see from the delta how well the HVAC is doing its job. Total cost was probably around $5 and I'll never have to try to figure out where I lost them. |

I have two thermometers permanently mounted: one to the output duct and the other to return duct at the fur[Of course, performance depends a lot on humidity. Do you have a hygrometer, and wall chart to be sure that you're not worrying about low delta T when your real problem is humidity?] No, I do not have a hygromeIt's easy to blame bad cooling on the AC, when the real problem is the humidity went up. ter. I'll have to look into that nace. Makes it easy to assure that the 20 degree differential is maintained. I've used the meat thermometer in the past to check automotive A/C status FWIW, I had my A/C serviced today and the tech used the attachment for his multimeter to do the readings. |

Sounds like the kitchen meat thermometer I used. That was pretty much standard equipment for all AC technicians at one time and they still work fine. I went a step further and drilled tight-fitting holes in my return-air duct and supply plenum at the furnace and permanently installed one of these thermometers in each. That way I can, with a glance, see both temperatures and see from the delta how well the HVAC is doing its job. Total cost was probably around $5 and I'll never have to try to figure out where I lost them. That's an interesting and worthwhile idea. Like you say, it's readily visible at any time as a quick check and you don't have to go looking for thermometers, where to put them, etc. |

I repair roll laminators for a living, I carry a one of those harbor freight ones, a customer went nuts, stating you cant have a gun in a sschool. i pointed it at my arm and the laser light came on and the customer went nuts till she saw the temperature read out. she believed it was a real gun......._ Did you take her temperature? She wanted a big gun. -- Tekkie *Please post a follow-up* |

baked good. (She's 50 and still weighs what she did in the 7th grade.) 179# ? When she stoppped working for them, I think they wanted the thermometer back, or maybe it was just the stopwatch they gave her for another client. A lot of her clients went out of business within a year after she was hired. Mystery shopping was their last ditch effort to find out what they were doing wrong. But Starbucks is still going strong. It's always "leadership" leading to poor customer service. They never look within because they always have the better idea. Coulda saved their money for the bankruptcy. -- Tekkie *Please post a follow-up* |

Measuring A/C Air Temp
Boris posted for all of us...
Hi, I'm having problems with my A/C. I'd like to measure the air temp. coming out of the ceiling vents. I've read that most infrared guns only read surface temps. I've had A?C repairmen over, and they look like they are using an infrared gun. What can I buy to accurately measure the air temp from the vents? TIA Go out immediately and buy a Fluke digital temperature meter. Measuring at the vents is only good for balancing home stuff. The real measurement is at the system; as others have noted to see if the system is working properly. -- Tekkie *Please post a follow-up* |
