I see that many are putting gauges on so I have a question (try not to beat me up too bad, I am trying to learn). Do you ever find a problem by way of the gauges that doesn't present itself by lack...

We check the same units every 6 months, some commercial stuff every 3. If we put gauges on that often every couple years each machine would be down a pound or so on refrigerant. It could also make...

I generally check motors amp draw, check capacitors, check voltage in/out across contactor, give all spade connections a little tug to see if they are tight, clean coils, vacuum out drain line and...

Our company charges x dollars an hour for leak search, not to mention what the repair may end up being. About an hour of searching is equivalent to the same price as applying the easy seal. If its a...

When changing out those compressors did you also change out the start relay?

At least in space it is easy to do a proper evacuation.

I did a tune up on one today that my company installed a few years ago. This was the first time I had the displeasure to deal with it. It had a 13d delta when I got there.Refrigeration lines were...

That's what happens when you put a woman behind the grill.

Prime example today, went on a no cool call this morning, found the unit had about 5 psi of refrigerant left in it, R410a. I added about half a pound of 22 and run the nitrogen in as high as my...

I gave him the short version of what i got from here and he was not pleased to say the least and said he would take care of it. I believe he will make it right. I hope.

I have decided the best thing for me to do in this case is recommend relocating the equipment for the proper line set size and length, or get trane involved if it must stay where it is.

Thanks for the replies. Printing that piping manual now, looks like something handy to have around. Boss wont be too thrilled though.

My company installed a new unit Friday, Comfortlink II, xl20i CU, TAM8 AH and xl900 stat. The problem is the existing line set was used, which is about 150 ft long, has a 30ft rise, and has a 1 1/8...
