Howdy, I'm new to the programming side of controls. I have a small project that I have been tasked with and for the life of me can't pencil it out in my head.

My customer has spec'd a maximum...

I just got the 2500 (gas) standard wheelbase...... It's a whole bowl of awesome to work out of. Room to spare, stand up in the back and seems to have plenty of power. I'm getting 15.7 mpg and have...

Don't think you can ask for much better..... Several years ago I had a similar issue, half the holes in the distributor had never been milled out. YMMV.

I'd do a load calc to verify system size is proper, without that you are guessing. Just because someone else put X in that does not indicate that it is right.

I'd put a data logger in the supply in the supply and one in the house someplace. Let them run for a week and see what's really up. Slowing the air flow down will remove more moisture. Increasing...

I have quite a few spreadsheets that I use on my palm. cfm calcs, electrical calcs, pt calcs, just to name a few. I use it all the time.

TIF ZX-1 better detector than any other in many side by side tests. I always thought only 2 things belong inside of a refrigerant system....refrigerant and oil. Dye is not one of those

Is anyone using a mapping GPS to get around instead of a paper map? I was just given one by a friend and havent touched a map in a week or so. This GPS tells me when to turn and if I miss the turn it...

TIF ZX-1 Good down to .1 oz loss per year on R-22. Crack a bottle and do a side by side test. The TIF will pick up the leak first everytime.

Thanks R-12

I do have a good job that pays well.

The cases are all working right. The drains are just getting plugged once in awhile. Howabout making those plastic things and the pricing tags. out of something that disolves over a period of time...

Hey Guys,
I HATE commercial refrigeration. Now that thats out of the way, it seems that we spend a fair amount of time de-icing froze up cases. The majority of the problems are caused by plugged...

I'd be designing this crap. Instead I'm out till the wee hours fixing it.

So how hot can your get txv's before you cause damage. I've seen people braze them in w/o wrapping them and counted them as foolish.

I WISH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Target anyone that is hiring. You are employable in this field, but only as a helper. Your resume tells your prospective employer that your have taken a year of class. When asked and you will be...

I've never heard of that until now. I did install a 1p compressor in a 3p unit once though, it did'nt run for long.

Thanks Guys now I have a HEADACHE!!!!

condenser and evap is flooded. Unit looks somewhat overcharged. You might want to pull all the gas out and start over.

Its great equipment. You should jump at the chance to become a Water Furnace Dealer.

If you have any sense about you, you will find something else to do before you get TRAPPED. Like a job where you get to have a life, regular hours, not on call all the time. Don't get me wrong I love...

I think that I would be looking at floodback.

I used to be like you. No use for core depressors. But I am in HVAC now, and those damn units do not come with access service valves, just schrader ports. I hate them. But I am like...

Hi guys,
Long time no visit, been a busy summer. Hey what brand of leak detectors do you guys use. I have a D-Tek that I distrust more and more (even w/ a new tip). Have any of you tried the new...

I think they had an electronic air cleaner. Salesman said it only needed to be cleaned every 6 months.
I HATE THOSE DARN things. A .59 filter from walmart does a better job.

God at the top
