I upgraded from free version to pro for a few months. I wanted to include photos to simple report. I don’t see where to do that. I don’t see any difference between free and pro. I have tried...

I need to swing by and look at meter. I would be surprised if it’s 5#. We are replacing heat exchanger and a general rebuild of heat section(better idea would of been to replace unit)

I did find a picture I took in November. It’s a 325-5AL48. What does the A represent or is that just a superseded number. Grainger said they can get a 325-5L48 by Thursday. I was also looking on...

What is purpose of ops on regulator. I know the purpose. Is it really needed?? This is on a standard Trane rtu. Maxitrol stuff is back ordered. I can get a standard regulator locally We r replacing...

Do you guys find the pressure switch tester is worth the extra money

I think it said bac view. It plugged into sensors. They just changed set points with it

I Am a hvac tech working on series 48 20 ton rooftop. Runs fine in test mode no alarms on display. There are 6 vav boxes. I have taken care of this building for years. It’s always been a mystery...

Thought about replacing sensors first(I know not likely). I saw a post several years ago about replacing exv motor adaptor assembly and cable(llid assembly).

Is that the circuit board at exv??
...

We have received several high suction temp alarms and a low on charge alarm in history. I isolated to run only that circuit so I could verify charge( not much load). 281 head 115 suction 75 % exv...

I would imagine o2 would drop due to reduced air flow

Yeah I am going out with him. I understand watching co ppm as well as o2 when blower kicks on but what would I see if secondary was plugged thanks

I am working on a furnace with younger tech it’s a 90% with enclosed burners. It’s going off rollout that’s inside burnerThe limit is rated to trip at 180. I found temp does get to 180 on long run...

Will they display negative for trane voyager gas valves

I am looking for a small manometer that will fit in side pocket of tpxxl. It will need to do negative gas pressure. Do smart probes do negative gas pressure??. I have my tpxxl set up so I can do most...

we are working on carrier rtu with orifice header The compressor was replaced as well as evaporator orifice header. The tech didn’t install a filter drier instead just replaced with factory screen....

ok I returned to jobsite. I tested 3 of 4 that had resistance to ground but no continuity. they have all ran fine. The one I'm looking at now was reading 8M OHMS. I guess I never really noticed...

We repair 9000 btu climatemaster heat pumps for a hotel. We have an on-site testing station. I have repaired many. I typically check windings and external overload. If I see resistance to ground I...

Looking for suggestions on small setup with tote to carry on roofs. I was looking at victor in Johnstone catalog some said can braze 1/4 to 1.5 others said 1/2 to 1.5 thanks

no to reactor

i have a 40ton vfd automation direct gs34040 vfd. it has been in for 4 years no issues. its a 480 drive. 486/482/482 input voltage. it went in alarm sunday. i looked at today. it alarmed out if it...

There was a dead stinkbug on board??lol

M#UAPM-036JEZ

Code 28 is voltage is too high. I shut it off to clean condensor. The voltage is 246.7. Does anyone know what voltage limit is. I have unit right beside it with same voltage and it seems fine. The...

I did check inlet gas pressure to boiler gas regulator. The inlet gas pressure was around 10" on startup. When boiler fired inlet gas pressure dropped to around 9". The boiler regulator did the same...

I suspect it gas been like this for awhile. They are not having issues with boiler. The jnspector just wanted low gas switch replaced cause it had no cover. Idont know why old switch doesnt trip(it...

I have 8-10" wc outlet pressure on a rv91 regulator with plated spring(which should be 3-6"). When boiler lights off pressure goes to almost zero then up to around 2. The issue i am having is new low...

I just took over several chillers with turbocor compressors. We are onsight starting pm. I noticed discharge check valves rattle when compressors are down below 20%. I did have training in Toronto....

Can someone explain how exactly this is measured.
Liquid temp -leaving water
Is it measured on liquid line or is it saturated liquid temp(liquid pressure converted to temp)thanks

does that mean it will be live data

You have to have testo app open and share data. It works good but it isn't live data like smart probes

I am definitely going the wireless route. I am trying to decide the best route. There Is a good deal on testo at trutech tools. Do you guys usually go through the full measurequick app on every...

are there any differences between the older 2 piece flaring tools and the newer orbital with clutch like the hilmor besides more user friendly features. I was told the older tools dont make correct...

It is to open at 7# (r22). I checked charge on both circuits. It's fine. I had to replace lvg water sensor in July. I checked flow back then it was fine. This thing may trip once a day. It went all...

I have a chiller that trips once a day or so. The charge looks fine. I am going to replace switch. Any other ideas besides exv hanging up. Thanks

I am up to 16 degree split now

Just a fan coil. I have hot water baseboard for heat

Duct board and flex. It doesnt seem to be losing it through the ductwork a degree or so. Seems to be losing through ahu. Anyone ever insulate ahu with black armaflex sheet

This is at my house. It is a 2 ton straight ac ahu in attic piston metering device. It has been struggling runs alot never shuts off till it cools off now that hot. Just wanted make sure I'm not...

We do pms there. Another tech said unit was working ok I am going to go to dig a little deeper.

I work on alot of large desiccant dehumidifiers. They are designed to remove a certain amount of...

I am going on a call monday that space is 60%. And floors even become wet. I will check charge airflow thermostat location run time etc. Is there a way to determine that unit is pulling out...

The book said check sensors and compare to ohm chart. I did that and they seem fine(oa,ra,ma) But the OHS AND RHS SAID check 4-20. I did that but got no reading

Yeah I did that but no reading

I am working on an issue Trane package unit YCD330A. the customer stated it was 80 degrees in all zones. This is a vav unit with a tracker system. It gas the LCI SERIAL board with serial cable. The...

Do you just have the standard 2 pressure probes,2 air probes 2 clamps or do you keep more on hand

What exactly do you use to add charge just an access tee??

Mark,

Do you use fieldpiece all the time as in svc calls charging etc. Not just when someone wants a report. Been thinking of going wireless

What are most of you using measurequick with??feildpiece or testo wireless. Do you use the wireless exclusively when charging also. Been looking at going wireless still using testo 550

Model ac10b36-b

Can someone tell me what run cap and contractor is in this straight A.C. unit
I am checking it for a friend this weekend want to make sure I have correct parts not taking van
