Hello. I am new to the issue of air conditioning repair. I did a course in Lomas de Zamora, but I could never buy a tool. Well let's get to the point, I installed my air conditioner is a cold only Bgh of 3500 watts, use R410A gas. According to the factory label, it says that it has 520g of gas. I installed everything well and occasionally it freezes the high pipe. Today I measured the pressure and it marks 85 psi. The ambient temperature is 27 g. Will you lack gas? I clarify the tools I rented them to a neighbor. I want to buy a vacuum pump but I don't know, what to start with. From already thank you very much.

Hello Most likely, they have done the uninstallation badly or there has been a lost or badly closed burglar or possibly already had little gas before ... you must empty the equipment completely, discard the old charge and charge new refrigerant from scratch in liquid phase and I recommend you use a diffuser to pass it to gas since you do not have experience and you could damage the equipment. Before all that you must make sure that there is no obstruction and that the indoor unit works well with good air flow regards

Thank you very much for your great contribution. If I am going to buy the diffuser for r410a. What happens if I don't use the diffuser? I did the detoxification, I saved the gas, for 30 seconds I left the spout open to suck all the gas. That had been taught to me in the course. And you recommend that you throw away all the gas and complete it with the 520 g. What does it say on the label? Thank you in advance for all your contributions.

Actually waiting for 30 seconds in the packaging, it would not be bad but it is still working in the air, the ideal is by manometer reading
You must discard all the gas, that already works because, due to the difference in density of its components, losing more than 20% of the total changes its composition

It could be. Is the equipment clean? It's new? The filters are not covered? The r 410 work between 105 and 120 psi depending on the ambient temperature

Hi Lucas, thanks for your answer. I moved and reinstalled after 7 months. But if it is new very little use. It does not reach the year of use, filtered them wash them before putting on, layers that in moving when I did the gas storage, open lost something. Lucas sorry for the inconvenience, what pump do you recommend to start? Which would be one for a / a of up to 5,000, 6,000 fridges. Thank you in advance for your prompt response.

If there was a lack of gas, you should rule out leakage, pressurize at 500psi with nitrogen, if there are no leaks, sweep, then empty. A 3 CFM pump is enough.

I do not know how you started the equipment because if you are using the method swept with the gas itself to get the air out of the system, it may be that the gas you are missing has escaped. Before committing lowering the equipment and looking for possible leaks I recommend that you add the lack of gas that is needed at that ambient temperature of 27g should be at 115 psi then with soap water check the rebobinete and union nuts and already after A few days you check the pressure if it is the same.

Your recommendation to add the missing refrigerant, in the case of r410a, is not appropriate

Basically it is for the same reason that it should be charged in liquid phase, now what is strange to me is that you are not a colleague who occasionally walks here, you are every day and this was said a hundred times so you surely read it more than once not only from me but from other colleagues as well,
