How good are these for HVAC work?

They do offer some protection, but ideally you want two things these don't have.1) Protection from cuts on the edge of metal sheeting from a glove with a kevlar palm and fingers.2) Superior grip of smooth metal from finger tips coated in rubber or silicone.However, both of these things add to the cost of a glove, and they will still wear out with regular use so the level of protection you want has to be weighed against the cost to have it.In some parts of the work like fabrication you might be working a lot with sheet metal screws. In that case you might also want a 2nd pair of gloves with a finger or two cut out for best grasp of small screws.

I can't vouch for their efficacy for that line of work. They are a tight fitting, flexible glove. I actually bought mine to use as light/medium weight motorcycle gloves.

I would not use them for that. You need something that air will actively be pushed thru.

I put new ones in about a year ago, our house was build in 2004 and it seemed that the "contractor grade" air vents were what you would expect. So far the new ones seem to work okay without any problems.

that is due to the human comfort level being above 55 degrees and these are designed for work HVAC systems if you would like a temperature setting below that you should go to a digital refrigerator thermostat like for a walk inI'm not sure I understand what your application ismore info

It should be fine. They are shipped to us normal ground so have several days unrefrigerated on the way to us and I have never had a problem with them working.

They do pretty good. I use them when I cut grass and vacuum. When I cut grass I put ear muffs over them and can't hear anything and I can't hear the vacuum when I'm using it.

They are ideal for pets. The housing is cool, the low design is more stable and will take a little rough housing without falling over, and the blower can be easily angled to suit both you and your pets preferences. I've had two dogs and a cat happily live with this heater. The dog beds are about eight feet away and both LOVE it. Also perfect for warming my cold legs and feet under desk. I've just purchased a third one this year. I use one to heat a green house.

I have installed probably more than a 100 of these for my business and haven't had a problem with one of them. I have installed them in areas sheltered and unsheltered without any issues.

Should be fine. They have been fired at a much higher temp. They are made for the heat. We use ours for everything.

If you mean 20 below, no way will these work. If you mean 20 degrees, you may be ok if your activity level is high since they're rubber on the outside with a thin layer of fleece on the inside and they will keep the heat in. They have a good grip and are completely waterproof. Small containers may be an issue depending on what the container is like. Hard to say about that. My husband uses them for shoveling snow in those temps and was fine. Hope that helps.

I don't know if they are the best and I think a lot depends on your carpet. I run them on a commercial grade level loop carpet and they work just fine.

If you have to do commercial work with them. They are too small. But if you're just working around the house or doing automotive underneath a shade tree. They'll do. I was going to send them back, But I kept them.

I have eight of them working o n different angles of my property. I'm quite happy with the clarity during the day and with light they are pretty good at night. The infra red works great in close proximity. UIf You don't mind an estimation ,,I would say they are good out to about 40 degrees. Wider with distance.

I use them for vaping and they work quite well. I have an itaste svd with 2.1 ohm dual coil.

They are just fine at room temperature. I would only use a heater if the temperature dropped below 68.

It worked well on my vehicles. I have not tried it on other HVAC. I am sorry.

Temp ranges vary with manufacturers but the range is sufficient for hvac work and yes u can put them in water.
