I was told to do this once, I called the service advisor at gustave a Larsen, he told me that is not an approved way to clean a coil

You won't regret the veto!

You can tell the foam fell out of the roof truss cavity, it must have been damp and the foam just dropped instead of grabbing the wood

Not exactly how you recover ammonia, lol , but it makes it safe to dump down the drain per say. 6" bubble? How bad are hot rodding that drain down

I have a bosch pocket impact that works great on those screws. Let it rap a couple times real slow and they usually bust free.

I've never heard of using the amp draw, ill...

According to the rep at Larsen they were out of range. Where did you get your info from? Im more worried about getting things done right than my ego

I was more curious if different igniters had different ohm ratings. I know the 80 volt ign are lower than the 120 volt.

One of the reps from gustave Larsen finally got back to me. Per the rep he said anything over 80 has the potential to fail and should be replaced.... I'll stick to my 100-110 range

I've tried finding specs, anyone have any idea where they can be found.

Just curious what everyone does as far as replacement for hot surface igniters. Usually I try to replace them when they get around 100-110 ohms. Have a couple units that are at 140 and 170 ohms. I'm...

Company recently got iPad minis for billing. I was wondering what billing programs do most of you guys use and if there were any good apps for time sheets. Any tips on keeping info on individual...

I thought of that, but the evap manifold gets cold when it does run

York Model Y13AC04A2AAAABC Serial S NDLM030707 R-22. Unit has 3 coils in this setup /\/. Far Right is compressor 1 coil, middle is compressor 3 coil and Far left is Compressor 2 coil. Compressors...

Im guessing by cooling the tank your getting it closer to becoming a liquid inside the tank and making it easier to dump more refrig inside?

I have a set, haven't used them a ton. Mine came with regular hoses, have to find a set with ball valves. That's my only complaint so far

if you wanna know if your cap tube is plugged look for frost..... The refrigerant will release its pressure and the temp of the refrig will drop inside of the cap tube. Think a mini cap tube inside...

I would check to make sure you have 24 volts at the contactor. If not then you need to go back to the board on the furnace. If you do have 24 volts at the coil, push the contactor in. Do you have 240...

I believe they justify using a drier that small because they unit and should not have a lot of junk in the system until its run for alota hours.... i believe the units call for a bigger drier when...

Anyone have any experience with these furnaces or ac units? overall value, quality or problems?

I believe if you click on forum and then go down, there is a section that says how to join followed by several pro sections.

I appreciate the help and everyones input, and im sure everyone on this forum has been at the point where they have been in the sun all day, got home feeling beaten down because your lost and looking...

This unit was ran for three years with it intermittent tripping breaker... at this point its at every 3 hrs when I was called. It was murdered

One lead to ground, one lead to the start winding.also the unit has a scroll

The merger lit up the first light which is twenty....

I came to this site because I know alota guys know a lot more about this and I don't feel like ****ing the home owner over. How bout a little more help versus trying to put someone down. After all if...

I realize I didn't go about this in the most logical way but you can really **** off with your condescending bull****..... just because you think your **** doesn't stink and your always right doesn't...

What is the difference between the three wire and the four wire method? Also I have a few questions about the wiring on the motor. I think I have it wired correctly but it only will rotate one...

I had the same problem when I started out and thought every refrigerant should have a general operating range. Truth is there are a lot of variables and it would be better to work on using the...

Ive never seen them come standard on CU, but most of my experience is on refrigeration and Ice makers. Mayber check with manufacture to see if it came installed, im guessing a tech put it on.

If you call Scotsman tech line they will help you out if your stuck, the guys they have in house are great. Does this unit have a hot gas defrost on the evaporator? I have had those things let...

Some people put them in the condensing unit because of previous or other problems. Short run times... etc. If there was one, im guessing it would be by the contactor. I ususally cut the control wire...

The unit was a txv, the whole scenario was bothering me so I went back over to the homeowners house to take some additional information. I megged the compressor and both run and start windings were...

That's totally fair, I have no problems with that. This is the first time I've seen something like this and I should have taken better notes.

I went back through things in my mind, The suction was 75 and the head was around 150. I realize now I added refrig to an already overcharged system with 0 superheat.... 75 psi = 40 f, and my suction...

The reason I come on this forum and ask these questions is because im curious if and how ive made a mistake and want to learn from people that have more knowledge in the field than I do... I take...

Ive never heard anything about time from my employer, like I said before I should have checked it but elected not too. The question was also missed.... if the unit runs for twenty mins, its not...

While I did not check the voltage at the compressor and you are right I should have.... If the compressor will run for 20 mins and then shut down when the house is satisfied, but will have problems...

I did not ohm the compressor. The only time the unit trips the breaker is upon restart of the compressor after everything is close to equalizing. Unit is from 2007, and is a 14 seer unit. Home owner...

I have a Ruud unit that was tripping a 30 amp breaker every two to three hours. The unit was running with 0 superheat and upon initial start up would sen 70 amps to the compressor and quickly jump...

Stay away from this pile of junk, had one for 6 months.... then wouldnt register anything. Cleaned it out and nothing, and not having a valve core depresser blows

If you work on the roof alot get a Veto, Plastic tub for a bottom, and throw the big shoulder strap over your back

This may seem like a dumb question, but are you burring out the tubing before you make a flare?

They cant suck worse than those JB's

Bought a set of Jb valve removal tools and the things are absolutely horrible. The roll pin that holds the end on walks all over the place and took out the ball valve and the o ring on the back of...

The valve was a danfoss and someone installed it incorrectly. There is no J tube, and it is feed above the valve with the powerhead going horizontal. The temps I took across the refrig lines lead to...

Another thing that can screw these guys up is the incoming water temperature

If you have max freeze time faults you either have a low charge or the discharge and water temp sensor harnass is probably faulty.

Is there proper spacing around the units?

Are the air filters...

does it have that adaptive defrost?

If were talking a cooling tower than were talking alota heat. The water is reused and yes some evaporates. How big of a system are you talking? The one I worked on was a 60,000 lb ammonia system.

Also should look at a water softning system to help alleviate the hard water problem.
