Doubt about installation that made me in split air
Hello friend, in the first place, they are not installers, they are chantas, you should not throw refrigerant into the atmosphere, the vacuum is paramount, because not only do you eliminate the air and the humidity of the pipe but it also serves to verify that there are no losses in the connections, what they did is just what should not be done, it is difficult to know what amount of refrigerant they removed from the total load, they should control the working pressures to know if it is necessary to replace. I hope it serves you, greetings
Yes, the truth is that I think that. I feel like they scammed me. They charged me $ 5000 for the installation, which I paid confidently that they were going to do the procedures correctly, since they are enrolled but no, nothing empty, loss control, etc. I hired them to have the guarantee, but they even want to charge me the VAT to make me an invoice B. It was better to hire an acquaintance who is not enrolled but knows a lot and does things accordingly: /
Thank you very much Pablo, for your kind assessments and thanks for the communication. Good luck I wish you success in the future S @ lu2 friovega63.
Thank you very much for your complete and clear response.
It is the first time I have a split, I noticed that it takes longer to cool than a window air that had lower refrigerators in a larger environment. I don't know if it is due to the installation they made or if there is any notable difference in the cooling speed of each one.
I don't know what the solution would be to the issue of not having made a vacuum. I guess that emptying all the gas from the pipes and equipment, emptying and recharging with new refrigerant, is the issue worth it? Or do I think of it as an option for the future x example in 2 to 3 years?
Hello Pablo, as a consolation for his disappointment with this technician, I can tell you that perhaps the lack of knowledge, about the details of the ecological type mixture gases, could be the cause of the bad practices carried out. On the other hand the recommendation would be for a next maintenance, take into account your comment, removing all the refrigerant from the system, obviously empty and refill the system itself with a new refrigerant charge in liquid state, helped by a balance, to inject the exact weight, with the load indicated in the technical chapter of the equipment.
Thanks for your time. When I come I will ask if they can change my gas and do it properly, but he will tell me that nothing happens and that they work well as well. So I ask you one last question: being that I already spent a lot of money on the air, and it is not in my possibilities to make a change of refrig with another technician. Using it this summer like this (in case it cools well), and facing change next year is an option, or is it taking a lot of risk? Regards!
No Pablo, risk as such of gravity for that reason does not exist, if so note that it works relatively well, you can extend the change of refrigerant I repeat for later, for example for the next maintenance. The biggest drawback of vacuuming with the R-410A refrigerant itself is that when the refrigerant degrades due to the loss of a refrigerant from its mixture more than the other, its property of absorbing heat and lowering the temperature is canceled. As the system is designed to work with pressures that are now lost because another mixture is formed inside.
Thank you. I stay calm then. I was worried that apparently everything is going well, but silently some component or material is degrading. With all the knowledge acquired here I will be able to defend my position in case the air does not cool. Cheers
Today I contacted the owner, and I was able to solve the issue of the invoice. It gave me the option of returning half the value of the installation but I do not care about that, if the job is well done. I asked him to come to check the equipment since I don't feel it cool much, he told me he was coming and check the pressure he has, I don't know exactly how. Since I am going to ask you to measure the difference between the intake and the air outlet of the indoor unit with a thermometer to see how many ° C it is. I will tell you about changing the gas, taking into account the behavior. +
of the ecological type gas that friovega63 told me about. I don't think they will do it to me, and I don't know another registered technician where I live. Perhaps I should have accepted the return of labor, although not knowing what happens with the warranty. As an orientation ... if you could tell me how much a gas change comes out in a team of these, I would appreciate it. It is a Carrier 53HVA1201. Regards!
Friend do not be fooled with the "ENROLLED TECHNICIAN" since many chatter with the enrolled, but the reality is that THERE IS NO SUCH ENROLLMENT FOR REFRIGERATION TECHNIQUES, some trout card and chapear with that, but the reality is that such registration DOES NOT EXIST, legally it is not valid, there is NOBODY TO AVOID IT
