Posted by: Hvac

There are a lot of jobs that are out there that can almost guarentee you work no matter where you go. Some of these jobs require years of schooling though such as doctors or lawyers, but what about hvac technicians? They do not have to go through no where near as much as schooling as other professions have to go through, true, a doctor or a lawyer will make a lot more money than an hvac technician, but you will save yourself 10 years of schooling and about 100,000 dollars worth of college.

Refrigerators - What I know about them

Posted by: Hvac

I am very sorry but refrigerators are not my strong point when it comes to hvac, but then again because I know the refrigeration cycle, I can still trouble shoot refrigerators and most of the time I can pinpoint the problem and I can fix it. Although the design of a refrigerator compared to an air conditioning system may be different, teh principles of the refrigeration cycle will stay the same.

One thing that you will have to remember when you are working on refrigerators, that many of them will use different types of refrigerant than the common kinds that are found in air condtioning systems. This is because refrigerators do not need as much pressure, so the refriegerant will vary in a lot of cases. To be able to troubleshoot the freon part of refrigerators you will have to have a type 3 epa 608 certification, the last type there is and in my opinion it is the most difficult of the three certifications that you can get, as I failed the type 3 test the first time that I took it, and then I passed the second time.

Charging Air Conditioning Units

Posted by: Hvac

One of the most dangerous things that can happen to you when you are charging an air conditioning unit is that you can freeze the hell out of your hand, it sucks as I have done it before. The reason that this happened because I did not have low pressure loss fittings on my gauges, which is highly recommended by any hvac technician if you can afford them. They are not absolutely necessary to have, but if you are dealing with an hvac system that has high pressure, such as a split heating and cooling central air conditioning system then I would have them on the high side.

My HVAC School Introduction

Posted by: Hvac

Hello all and welcome to my HVAC and R school. First of all let me get this out of the way this is not a real accredited HVAC school. You cannot get a license from just simply reading and understanding all of the principles of HVAC. You will need to take 4 written tests to get certified given by an accredited school or HVAC instructor, I am not one of those. But what I can help you with is some training tools that will get you prepared to take your exam and pass so you can get qualified. I will also be teaching a lot about refrigeration and heating, how central air conditioning systems work, how refrigerators work, troubleshooting, and much more.
