I must be getting too old. It was a confusion on my part. It's not showing the TSH probably because the gauges aren't hooked up.

I have a Fieldpiece sman gauge and the fieldpiece psychrometer

When I try to find target superheat, it keeps asking for indoor dry bulb temp. Do I need to buy another fieldpiece psychrometer and...

My co-worker says they're one time use only, but I've been reusing mine for the last 12 years.

I can't seem to find the info on the box if it's reusable or not. If not, then I've been...

What brand do you use? I bought the C&D ones from Amazon. I've been using it multiple times a day, 5 days a week, and haven't had a single issue, but then again I've only been using it for 2 months....

I've known about them for the longest time and have always thought they were a neat tool, but never bothered to buy one

I had some Amazon gift cards a few months back and I saw one of them being...

Yeah, I just got your email thanks

I need help finding PTACs with a max temp 120 degree working condition

I hate how these companies aren't responding to my emails.

These new units we've been getting the last 10 years or so are practically disposable. Getting to the parts is next to impossible, there's less screws and more folded sheets of metal. We can't even...

I am the engineering staff on-site

These units have documentation but do not mention about maximum operating temperatures.

The old R22 units ran for decades, but they're just too old and parts...

We got a few different models. 2 types of Friedrichs and one ComfortMaster brand or something like that. I don't have the models with me, but we couldn't find any outside temperature working...

They're too new to be even serviced. Brand new units out of the box installed in the cans will overheat if it's 115 or higher outdoor temp

Dont think we have to worry about humidity issues here in...

So we have a couple thousand rooms with PTACs at the hotel I work at. Since this place was built, we've always used 1 ton PTACs. We've had problems the last around 10 years where the high limit or...

I've never done this before, but I've only heard about it

It uses mineral oil like R22, so you dont need to do anything other than recover the remaining R22, then charge with R422B. Maybe replace...

Is there a way to find out if a split system has a TXV or piston metering device without having to crawl in the attic and take the evaporator apart just to find out? It's such a pain having to take...

I keep reading this sightglass thing and someone told me once to just charge until the the sightglass is almost full of liquid?

I do air conditioning and have no experience with refrigeration. I went from working on PTACs, to residential air conditioning and now I'll be working as an in-house refrigeration technician.

I...

I'm sorry, I'm not too tech savvy. I have to figure out how to do that.

I've seen those, too, and I've seen the extensions

What's the purpose of these valves? I use Appion core valve removal tools when I'm working, so I have a working valve right next to the service...

I retired my old habor freight manifold and gauges after 10 years. I just bought a Fieldpiece Sman380v digital manifold as a replacement and I was thinking of getting Yellow Jacket's hoses with the...

That one's only for personal use. Vevor tanks are not DOT certified

I've never ordered tools there before, but the prices look about the same to me. I don't have any discount there.

Never, why?

Saying goodbye to my 10 year old harbor freight gauges and vacuum pump. Spent over $2k on these bad boys

I'm still weary of anything bluetooth

I don't even trust wifi. My PC is still hardwired.

I want to "upgrade" to a digital manifold system and I've been eyeing the Fieldpiece Sman 3 port digital manifold. It's pretty pricey.

There's a million different brands on Amazon that are a lot...

I'm really considering buying this. I want to know if anyone here has any experience with this tool. It's a cordless vacuum pump made by milwaukee. It's supposed to have a 90 minute run time per...

Does anyone know what the A2 error code means on Friedrich PTAC units? We have over 700 units and these happen every once in awhile. The manual doesn't show this code, Google isn't coming up with...

I'm calling Friedrich tomorrow and ask them which model PTACs have 120F max ambient temp

We normally don't do the ordering. It's Procurement that does it and cost is normally the deciding factor on what they get and when they order, it's usually a dozen or so pallets of these units.

I...

I'm trying to google ptacs with 120 max ambient temp and I'm having no luck

These units are brand spankin new. The coils can't get any cleaner. The older Sanyos have R-22. The new ones have 410a.

I work maintenance in a large hotel casino resort. We have over 2000 PTACs in our hotel. We have had several manufacturers from Sanyo to Friedrich and they all have the same problem. During the...

I give up. Good news is it'll save me a lot of money.

Maybe a big swamp cooler would be better at what I'm needing it for?

I'll be happy if the garage is 90 and it gets down to 80 in 1 hour. The hottest the garage ever gets is around 92.

Why do I deserve a crappy job just because I want the condenser in the backyard instead of the side of the house? If it can't be done, it can't be done, but this is what I prefer them to do.

I'll be getting a quote for them to run the lineset and power to my backyard as well. I don't want the condenser to be seen from the front of the house. I currently have it on the side, but the...

I looked that up and it's too complicated for me. I talked to a contractor and he recommended the 30k BTU one from what I was explaining to him what I needed the unit for. I'll talk to 2 other...

It was the contractor that told me 9k BTU was good enough in the first place. I even asked him a 2nd time before making the purchase from Amazon for them to install. I showed him on my phone the...

I have a 2 car garage in Las Vegas, NV. I have a Senville 9k BTU mini split that someone installed over 2 years ago and it can't keep up with the heat in the summer or cold in the winter.

I want...

I work maintenance in Las Vegas in one of the large hotels/casinos. We use PTACs in the hotels. We've gone through several different brands of units from Sanyos to Friedrichs to now, ComfortAire by...

I had someone install my Samsung 12k BTU mini split in my garage a year ago. I have had it on heat over the winter and I turned it on cool for the first time today and air is coming out, but it's not...

I mainly work in-house at a large casino/hotel. I mainly work on PTACs, reach-ins, walk-ins and mostly I'm the guy they send to run electrical, wiring motors, electrical troubleshooting and for the...

yeah, why not? I have a universal EPA card and I'm a licensed electrician

After much thought, I'm installing it on the other wall. The same wall where the breaker panel is. I don't want people walking up to my house and see a condensing unit on the side by the front door....

throw it in my copper bucket. when it gets full, we sell it and it's pizza and burritos Friday for the guys in the shop



That's the easy way to do it, but having the lines hidden inside the...

Everything is going to be run inside the wall, including the power and drain. the problem is how many studs do I have to drill 3" holes into

comes with 16' of lineset

The bush will be to the side of the condenser, not restricting the air being pushed out. Not worried about the noise, as the unit will only be running when I'm working in the garage during hot or...

I'm having a small 115v mini split system installed in my 2 car garage. Inside is drywall, outside is stucko. The house is 10 years old.

It comes with a plastic sheeth to hide the refrigerant...

you got a picture by any chance?
