- Here we go over how to check refrigerant pressures and recharge mini splits. I know this is not the right way to do it but we do it on occasion when customers don't have the money to spend on getting it done right.

Thanks for the info, I’m a tech here in Escondido and for ever servicing these dude’s
@@matthewmorris1979 if you are good at service Escondido is not a bad place to be
Okay... I like how you guys work. Keep doing your best
Appreciate you guys, wish you were here in Italy.
Nice job 👏. There is usually a temp sensor inside to prevent freeze up. The flares are usually the leak points, and some will run lower evaporator saturation as the inverter ramps down to help dehum. Good call on trying to get it at full capacity to charge.
Nice job! Man that was a tight squeeze. I also usually poke around the flare joint at the service port with my leak detector for giggles should I get lucky. Loose flare nut. Great videos!
great video red some people just want a gas n go but like you said i break out the reclaimer and vacuum it gets pricey it will be a future recall nice !!!
I’ve read that you want to run cool mode in the max setting , check for pressures. This allows the electric expansion valve to fully open allowing for the best reading . I also bought the mini split instruction book from AC service tech . One of the best and most detailed books on mini splits . highly recommend it
Great video thou , don’t see too many on mini splits repairs .
We fix them a lot. Got some more videos coming out on them soon
Great vid guys. I took a class some time ago where they said superheat and amps could also be used, max cooling, less than 5 degrees of superheat and 80-100% on amps and let er eat
I just want to emphasize that this type of repair is not necessarily "recommended" in any circumstance. Mini splits especially should be fixed when they are leaking. Sometimes we run into circumstances where homeowners or business owners do not want to fix the issue for one reason or another and this is essentially a temporary fix that we can do. In this instant the unit is a back house and the system is 6 years old. The homeowner basically didn't care to spend the money to get it fixed. This unit is also just not very serviceable in general due to not having proper clearances so it would have been very difficult to talk on the outdoor flares and the indoor flares supposedly being located in the wall - we did not confirm this but it happens way too often. This customer understood very explicitly that if the refrigerant leaks out within the next 1-2 years they would have to pay to get it fixed properly. We do not add leak sealant to mini splits as the leaks are generally at the flares.
The eev sometimes makes you think it’s low on start up. The only way to know is recover and weigh and weigh back in.
So you’re saying you can’t trust the PSI at startup to determine refrigerant levels?
👋 @9:38 You mean the system was at 177 PSI when off? Do you know what the approx ambient temp was?
@@Katana_00 no clue
@@SurfBrosHVACall I need is a date + approx time and city 🤣 I can look up the temp
Start with delta T
You need to reclaim refrigerant and weigh in charge
I talk about this in the video. Yes this is ideal but not everyone wants to pay to have it done the right way
@@SurfBrosHVAC the problem is they will tell you to go ahead and do it and hope for the best but when it fails they'll blame you.
Excellent video !! Shitty location !!! What brand of digital torque wrench 🔧 do you endorse ??? NAVAC, HILMOR, Yellow jacket or CPS BLACK MAX ???
Honestly I don’t have a preference for any brand. Unless someone were to prove different I think they should all work well. I think ours is yellow jacket
THANK YOU SurfBros, There isn't much out there on adding a little bit of Freon to a mini split..... and Yes I know you are suppose to recover/weigh..... Not everything is in a perfect scenario.
