filter? what filter?

Pic no.2 is a beaut, i never knew r/v standed for relief valve

I will accept your reasoning, but if they don't close they don't pass, that one has always been around, flange mounting and others do also come under a clause in the act regarding design and...

I have found several f/d's that have never been registered, so for over 30 years no one has checked an essiential safety piece of equipment

Look at the access compaired to my hand size

So the company I work for has had a contract of a large commercial site and have never done a fire damper inspection. Last tested in '05, so all the techs have been telling management that they need...

don't think it matters now if the question way asked in 2004. LOL. prob has already had a comp changed.

Love your work, LOL

is this the same unit you had issues with in 2006, thread http://hvac-talk.com/vbb/showthread.php?t=110568

what refrigerant? pressures? set point?

more than likely an outside air in take, not sure of U.S law in residential, 10% required here in Aust

sounds like you need a proper hvac tech out there, in further posts you need to have some more info, e.g model no. age of unit, ref, get a service docket from the next person that attends so we can...

NON CONDENSABLES, the wording is where all the answers are, it's in the high side, sub cooling needs to be checked not the air on air off (coil differential)

Only one person has managed to respond to the op question. I usally say 15 -20 years, by that time there are alot of new options and power saving advantages to upgrade anyway. If a buisness can...

Why didn't you replace the disconnect on the wall this time around?

Was the TxV changed at the indoor coil? Maybe sized it wrong. Don't like when units are mis matched causes way too many problems that could easily be avoided. Like all previous posts, I think you...

Replace it, while your there, fix up the pipe work and get some better saddling in. Maybe look ing a weather proof cover over the unit as well, might extend expected life span

You may think he is on the right track but from the amount of investigation he has to of gone through, and adding freon just because you change fan speeds :eek: Maybe get someone else to finish the...

Straight away I can tell you I think it has non condensables in the system

I can remember my first good ref burn. I was an apprentice, and we were charging up a unit. The bottle was new and was one of the first to have 2 valves/ports for liquid and vapour charging, check...

A refrigerant burn is no diffrent to any other burn, you took the right step in running water over the area, you should do this for up to 20 min, but further action is required afterwards, a wound...

That'll go back down once everything goes back to norm, way over priced at the moment. Aussies are alright but you can still find the ppl who don't respect where they come from, or where other ppl...

It's hard to say, on the road for a company, a lead tech can earn between 34 and 36 AUD. Office supervisors and building managers can pull 150 grand if its a good contract. There are so many avenues...

Depends on the age and location (suburb or town house is in), in the earlier homes around 60's to 70's gas would be used and the kitchen would be gas as well (stove top, oven), after that depending...

In a commercial building you would typicaly see nat gas, but there are still a couple of old deisel burners around. electric re heats are also very common.
