The pressures for a 410A refrigerant depends alot on ambient conditions. A 40°F evaporator would give you 118 lbs on the suction side or low side. On the high side and a 95°F ambient temperature you'll generate 295 -300 psig or lbs on the discharge side, or high side

You can do most stuff your self, change filter, clean outside coils, etc. I know electrical so I'll do anything related to that, replace starter cap, contactor, etc. If you have a heat pump, remove the fan cover and rust proof it the best you can, and replace the caps on the valves if there plastic with brass ones that have rubber seals in them. Sometimes a slow leak in the valve will lose Freon and don't need to get bent over to have it fixed if you can seal it with the cap. Nylog works great to around the valves.

I thought it was the cap but just the valve did not seat right took the cap off and there were bubbles .. Pop came out this time when I put Freon in it only 2 pounds and it is cold in the house..

Amazing the marketing campaign STILL getting people to call refrigerant "Freon". It has been almost 3 generations and they have such a small percentage of the market. I was unaware Freon was still available until I actually saw a guy use it in July of this year. At least with Kleenex it was on most every shelf. I really don't know how Freon could have been such an effective campaign. Chemours Company now owns the trademark Freon but originally Dow had it when introducing R 12 which really changed peoples lives. I just thought by this generation of techs the habit would be gone. You guys have chosen one of the more difficult trades and they keep throwing technology at you... that should demand higher pay for the techs. Great job... run your own business and make what you deserve. Just noticed that this is 5 years old. Does youtube not have current videos??? 🤣

@@anthonym6843 I realize that, and to be honest, I think it's kind of interesting that subcool readings can vary on any particular system dependent on its operating pressure/ambient conditions. He could have mentioned that as well. I like this young guy, he's a great ambassador for our industry. I was just raising the issue because I only lasted exactly 30 days in my previous job. I was assigned to work with the companies "top mechanic" all but two days and I was stunned to learn the guy was so "old school", he felt taking subcool readings were unnecessary despite the fact I told him these readings are carefully calculated, that they're actually predictable in a properly charged system. The guy was also unable to use a meter but that could have been more an issue he could not read ladder wiring diagrams. He would literally "TUG" on a pair of wires all the way back to the control panel. I was fired the day I challenged his lack of skills. He also used soap bubbles to leak test. He used soap bubbles to do his initial leak tests. Who does that??? He does!!! I never saw anything quite like it and when I confronted him and his inability to troubleshoot, I received a phone call from the office about an hour later asking me to report to the office at the end of the day which is when they fired me. All the owner said was he was surprised at my behavior and that I should have known better. In a way, I got fired because I stood up for defending the importance of taking subcool readings, so I still have a shot at making it into heaven. LOL!

Hi Ben, I have a 3.5 ton 14 SEER Goodman packaged heat pump on my house, I'm pretty sure I'm on borrowed time considering I had this unit put in back in the summer of 2009. I noticed lately that almost my entire compressor, the entire accumulator, and most of the fixed metering device is completely covered in condensation, I live in Florida and I assume a lot of this is due to the high humidity here, I also noticed that the insulation under the top cover of the unit fell apart. About a week ago I cleaned the condensing and evap cores on it, the fins on the condensing core are flaking off in a few spots due to the age of it, but nothing super excessive, the evap core is still solid. I had been noticing the compressor was much louder on start up and even when running was a bit louder than it had been, I replaced the dual run cap with an Amrad with the CPT terminal, the cap is a 45/5 mfd, I put a 5-2-1 hard start kit in it with the separate potential relay, the contacts on the contactor looked a bit burnt, it was still working, but I replaced it just to be safe. I did notice after replacing these items the compressor starts up faster and quieter and seems to be running quieter too. I noticed that after doing all of this that the air blowing off the condenser fan isn't as hot as it once was and there is less condensation draining out of the unit. It is still cooling my house and has cold air coming out of the vents. The cap and contactor I replaced were the factory originals with the unit, I tested the original cap out of curiosity and it is supposed to be a 45/5 but it was only giving me 29/3 mfd's. Could the compressor have sustained some damage from running with a weak cap all this time and is this amount of time and is this amount of condensation on it normal? Would the fact that the insulation on the top cover of the unit is gone have anything to do with this?

Isn't there a reference chart inside the cabinet or isn't there a reference chart that come with the refrigerant, so you can check pressures as they should be based on tonnage of the unit (3 ton unit I'm my case) and ambient temperature 98f the day my unit installed. As ambient temperatures increase so do the pressures, which my techs failed to do. They based their pressures on a normal day like yours, my accumulator sweating like crazy, and worry, pressures too low. Dealer won't check charts to make sure pressures are where they should be.

@anthonym6843 Жыл бұрын
Is it freezing up in cooling or heating mode? If its in heating, it will freeze in low ambient temps. Make sure your defrost board is working, if it’s not going into defrost you got a bad board, or defrost sensor. If its freezing in cooling youre most likely low on refrigerant, which means you got a leak somewhere.

Pressures alone shouldn't be used to tell if the unit is properly charged regardless of the metering device type. txvs regulate superheat, not pressure alone - you can have low suction pressure caused by low airflow as an example, doesn't mean the valve is bad. check superheat/subcool to really see what's going on in a system.

The low side is reading 40f on gauge and the temp prop on the low side read 68f So the high side pressure is about 345psi and the low side is about 145psi based on the guages reading The outside temp was 74f afternoon The system is roof mount train Thanks
