I agree!

TY, I always look foward to your videos. I found that hearing you go over the cooling process over and over on each video helps me comit to memory the terminoligy and effect and result of each process. Thanks!

My boss would say when it gets to 65 outside turn off the air because the coil is going to freeze. I always thought that he was lying and he just did not want to spend the money cooling the business. Years later I learned why the coils would freeze. And you here are re-affirming that. Nice video. Thank you.

Really wished you were my instructor when I was in school. I feel like I wasted my money.

It's me again, Thank you for making my day smarter.

I’m a senior tech, I tell you one thing. I really enjoy your videos and I’m always checking for more. Thanx a ton

ABC= airflow before charge

Your videos are a combination of all the best seminars or sit in classes, HVAC School’s and factory training all put into one. I wonder how many old-timers are watching your videos with 20 or 30 years experience but are embarrassed or ashamed they would not admit that they are watching HVAC 101 and learning something new for the first time. Keep up the fantastic work

I ❤️ your videos!!! i watch them daily

Been in the trade for 6 years +, which seems a little but easily many others in ability. I am so thankful for having come across good sources of info such as yours Ty, you’re the man. People don’t realize the importance of these fundamentals , and how they will affect your development as a technician or wherever your going in this trade. There’s guys out there who’ve been in the field for over 15 years and still don’t know this stuff. New guys Follow Ty and his content, you won’t regret it. Keep up the good work Ty we need properly trained techs in our field to fill a lot of jobs. 👍

Thank you very much for your help and the gorgeous course. You are the best

Thumbs up for the X,X, check on various types of blowers. 'tis the season again. Watch me wait until it's too hot to use the attic during business hours, same as last year.

Thanks for posting. I enjoyed the presentation.

Hi Mr. Ty, I regularly watch your channel. May i request you to share same video (may be afterwards in future) explaining same concept simultaneously with P-h chart.... How the suction & discharge pressures changes with change of indoor or outdoor temperatures or airflow... Thanks

When people ask me why an ac freezes I say there is only 1 reason an ac freezes, the coil temperature drops below freezing. The number 1 reason for that is usually air flow. But it's the temperature of the coil being below freezing is why it freezes.

Thanks ty

@@love2hvactropical island much like Hawaii but I think cheaper..

You mentioned someone adding refrigerant every year.... in my small town their is a shady service company. They replace my furnace, and put in a weird filter size that isn't in big box stores, only them and Amazon has that size. They also take care of my friend's ac unit. Every year it keeps tripping the breaker. "Shady inc" says they were just low on refrigerant and add more. This year they switched from central air to several window ACs. I think they said the compressor died, but now I have to check. System was 20 years old though. "Oh no your old system died, let me replace that with a new system."

Some sleazy companies put there for sure. Many cities have filter manufacturing companies that can make any size filter by the box for really cheap.

Hello Mr.Ty we can add fifth category which is the thermostat is still close circuit I mean R to Y close I didn’t if agree with me or not.Thankfully.🌹

Nice presentation you should also have mentioned them one inch pleated filters are too restrictive, I recommend a set up with a commercial four inch thick pleated filter to my customers, otherwise I tell them to use cheap filters and plan on having the evaporator checked periodically and cleaned if necessary. Believe it or not however, I have found the cheap filters if changed regularly do a pretty good job of keeping the coils clean. And I may be mistaken but I noticed that dirty filter you displayed looks like it was installed backwards, it would be worth mentioning that cross hatch cardboard pattern across one side of the filters face goes downstream of air flow and is meant to support a neglected dirty filter and keep it from getting sucked into the blower, and I have seen this happen.

Not all one inch filters are too restrictive. A lot goes into that and it will be covered before long. A restrictive filter will wear on a unit but also filter that lets the dirt past will have worse effects including ductwork contamination. The 2" filter was the right way, cross hatch cardboard was on both sides. The metal is on the back side that holds the media from pulling in when it gets dirty like that. Not my house I assure you. And I do love large filters but they are still not a clear cut answer.

👏👏👏👏

Thanks for your vids, Ty! How much caffeine do you consume in an average day? 🙃

How hot can/should the compressor discharge line (entering coil) be over ambient using approach method? I'm assuming this is the highest temperature of the entire system. You mentioned Las Vegas so when it's 110 degrees outside how high will you see? What might cause this to be too high. Could low refrigerant or air in the system inflate the temperature?

Come to my house please. You can do projects on everything

What is good filter can use it to protect the system? Is possible to use double filter? In charging refrigerant why not charge with vapor? If does what’s can happen? Thanks Mr. Ty.❄️💐

Great questions really greqt. Those will all be answered soon as the course progresses. There is not one size fits all and we must understand airflow before we can appreciate filters. So much more than people realize.

So a question I have, which might sound dumb but I can’t find any good answers online so far. I’ve gotten my Fieldpiece probes. And I’ve hooked them up on my system a few times. But I’m going to check my friends new houses AC, and I didn’t know, is it better to hook up probes/gauges when the system is off and equalized, or is it fine to hook them up while it’s running.

@love2hvac

2 жыл бұрын

I like to turn the power the probes and the app without them hooked up. GENERALLY speaking. If the unit is off I check everything I can while it's off. If the unit is running I check everything I can while it's running. So it really dosent matter. If you want to be super safety you could hook the high side up off and the low side while on for the least amount of pressure when attaching.
