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
Uh, I think it's called a thermometer.
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.

Probably don't need to buy anything...just hang a reasonable-quality thermometer from the vent in the air flow and you'll be well within accuracy needed.
Thermometer with a probe has always worked. Checking the vents helps, bur checking temp drop over the evap coil is good too.

That was my thought.
I use IR gun
Bed, Bath and Beyond, or any store with a kitchen department.
A popular model is 4 or 5 inches long, most of it probe, with a dial at the top. And a plastic sleeve to put the probe in. I have one somewhere.
I've used a kitchen meat thermometer. Just stick it in the vent. If it's a ceiling one, could use a piece of tape to hold it in for a few minutes to get a reading.

In the US, we have to register our IR guns, and cannot legally use them in public places or federal or state buildings.

HF had both digital and analog models.

I meant handheld thermometer using IR. I also have multimeter with temperature probe. Use to measure Delta T to make sure A/C is working good.
You fond of HF and loyal customer? I never buy serious stuffs from place like HF. All tools or gadgets I own will last my life time and beyond.
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.
Some times it's nice to be serious, other times it's acceptable to be comic.

I agree, HF is not "serious tools". But for most of my tasks, they are adequate.

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.
Yes, indeed. We don't have HF up[ here. Similar outfit is Princess auto. If I need some thing for one time use or don't care if it breaks after couple use, I go to Princess Auto. My idea of buying any thing is best I could afford. Or I save up to get what I want, LOL!
I repair roll laminators for a living, I carry a one of those harbor freigh t ones, a customer went nuts, stating you cant have a gun in a sschool. i p ointed 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...... .:):)_:)

honestly i dont use the heat gun often, i can look at the film and tell if its hot enough or too hot......
every now and then someone questions the temperature, after a couple got st olen i cheaped out with harbor freight
