just want u to know i been watching ur videos i got 6 weeks left of hvac school and ur videos are really informative thank you for everything i watch your videos and take notes everyday

Really clear. Thank you.

Just cleaned the coils on my system and my delta t is roughly 25-26 degrees, however the thermometer I used was an infrared one that I use for automotive use. The humidity inside the house is 28% and the t-stat is set to and showing 77F. The return is on the floor reading 70F and closest supply is showing 46F. I have a properly sized unit for my home and it’s southern Arizona with an outdoor temp of 90F and humidity of 9%. Blower speed is set to medium out of 5 speeds (low, medium low, medium, medium high, and high)

I would love to see a video like this explaining mini splits and how they work!

Fantastic video!

For the algorithm 🇺🇸

I always learn something new from these videos. Thank you!

Very very very great video

Another well made video!

Russ fear mongers natural gas explosive gas being in the customers homes while promoting heat pumps which now have to use a flammable refrigerant in 2025....

Thanks for the cool video! I was hoping it would show us how to use the charging charts on the condenser panel and take dry bulb/wet bulb measurements, but I still learned a lot from it!

Will share with my basic refrigeration students over the summer and provide them a jump on the Fall 2024! Thanks, Mr. Orr!

I appreciate the knowledge

Awesome information as usual! Thanks!

I have a r134a compressors and I have alarm low discharge superheat. I believe I have bad temperatures sensors.

Every video I see presupposes that the wires are "x" color with "y" stripe, or brown, black, etc. what if the colors are totally different. My new motor and old one both had a black wire, yet no other colors matched and none of them had a stripe. Both diagrams were different and I had no idea what to do. I tried many variations, but nada. I had an electrician take a look, but nada. I never figured that one out. 🤔 I would add a picture if I knew how. 🙄🧐

Hvac school is a gift from god for hvac techs all over

i there any game or website that help you like this.

Unfortunately, quality installation is contrary to the business goal - making profit. I would say it is for non-profit organizations. Ugly truth. 😁

how much does it cost to take the exam

So are they recording everything you do or not? Hhahahah! Probably. Then comes the claim that they were "hacked."

Very helpful! I was wondering why my charge hoses were leaking so badly when I was connecting to or disconnecting to the AC fittings on my pickup lately. I was loosing a lot of oil and refrigerant even with being quick to unscrew the hoses

The mp are looking good, they might expect grants from pm, but don't. Contain the number and fix the problem please, it's our country, it's our future.

What's the app call please respond

What about placing copper pennies in the drain pan?

Quick question I can't get a straight answer from anyone on this topic. Your thoughts would be greatly appreciated. Why when measuring voltage at a running compressor is there higher voltage than the input voltage?

5:56 you said EMF not EFM like it says there bud

High heat during summer causes voltage drops voltage imbalances caused by utility, contactor parts, ,electrician bus barr load. voltage imbalance calculator tool a good practice.

Blow out water after maintenance to prevent pressure trips and bubble parties that kill condenser motors

Microchannel coils notoriously easy to damage. Super expensive coil to replace 🧑‍⚕️

Check out Ductless Plus HVAC This install is not near as good!

Awesome

Measure quick charges you monthly it's not a free app

Good job. Please share to me news videos. Thanks.

My ductless had a refrigerant leak which caused a lot of condensation on the coil and wheel. I did this cleaning method but now I have a musty smell. The unit was thoroughly dried before starting back up again. Any ideas? 😫

Great video! Technical, morals and good business practices in one. If I may ask, what was the orange megohmeter that you were discussing at the end of the video?

Extremely well worded and presented.

Great video. My suction line is frosting up. Indoor temperature is 75F and outdoor ambient is 70F. It's r410a with low suction pressure. The low side saturation temp is 28F. I am getting low superheat but normal subcooling with fixed orifice. Filter is clean and air flow is good. The coil has no frost but frosting just before service valve at outdoor condenser. All amp draws are good. I tried adding some refrigerant but the low side pressure would not rise. I just can't figure this one out. Any help would be greatly appreciated. Thank you.

There is such a big difference in the quantities of refrigerants used in commercial versus residential and automotive applications. I just laugh at the paranoia surrounding the use of small amounts of straight up, hydrocarbon based refrigerants that are more efficient and have lower GWP. Quit being a bunch of paranoid babies and use freaking propane already in residential and automotive. FFS most houses have an unlimited supply of methane piped into them as we speak! This fear is being perpetuated AND SPONSORED by chemical companies that stand to loose millions if HFC is dropped in favor of HC. They are literally spending millions to make you fear flammable refrigerants.

What about all the decades of units installed without nitrogen and are still working perfectly. Just another added scam to make you pay more and sound more important to the customer.

How to know the this valve its energized when cooling or heating?.i appreciate your answer.great channel by the way

My space temp is ok but RH% is getting high and space vent is getting sweat. I need to bring that dew point need a dehumidifier. Filters r clean. Any recommendation?

brilliant explanation.

Low airflow = less capacity,less efficiency.
