The mechanical systems that are used for cooling, heating, and ventilation in an interior setting are referred to as HVACR (heating, ventilation, air conditioning, and refrigeration) systems. The world of HVACR is a great career opportunity but has a few myths that need dispelling. Contrary to what many believe, the HVACR industry has many diverse job opportunities for everybody.

Myth #1: You need a university degree.
The HVACR industry offers a wide range of career options; some need a university degree, while many do not. Though most occupations need more education than high school, you are not required to attend university. Only approximately one out of every ten jobs need a university degree, according to the Construction Sector Council.

Myth #2: In HVACR the only job opportunities are field positions
Professionals that can conceive, plan, and interact with both external and internal customers, and innovative individuals who welcome the use of constantly evolving technologies improving HVAC tools and systems, are needed in the HVACR business. In addition to the skilled trades’ careers, opportunities can be found in planning and project management, sales, marketing, administrative functions and more.

Myth #3: Working with HVAC Tools requires brute strength
This is an industry that thrives on new ideas! Through innovation and improved technology HVAC tools often require more brains than brawn. Today’s HVAC tools are more efficient, save time and are easier to use.

Myth #4: HVACR jobs don’t pay well.
Competitive pay is available in this field. Salary levels vary depending on the professional route chosen, but the field offers well-paid opportunities for those who are ready to put in the effort. If you opt to work in the trades, you will find that demand has grown for qualified, trained associates.

A refrigerant weight scale is an essential piece of equipment for an HVAC technician to have. A refrigerant weight scale is specifically meant to help install and maintain air conditioning units, measuring the weight of refrigerants when they are removed from an air conditioning unit’s compressor.

There are a few things that you should consider before you buy a refrigerant weight scale. Let’s look into a few of them below.

What is the Maximum Weight Capacity?
One of the main things that you need to know before purchasing a refrigerant weight scale is the scale’s weight capacity. You also need to understand the type of systems you will service and what is needed to get the job done. For most residential and light commercial jobs, a refrigerant weight scale that offers 115lbs would be sufficient. However, for larger commercial jobs a higher weight range will be needed.

What is the Resolution?
The resolution of a refrigerant weight scale is the smallest change or increment that can be measured. You will want to understand the accuracy needed for the jobs you perform. You can find scales with a resolution as small as 2g while many have a resolution of 5g to 10g.

What Is the Size and Weight of the Scale?
Because refrigerant weight scales need to be transported between sites, the size and weight of the scale can make a big difference in the overall ease of doing your job. Look for something that is compact and easy to transport. Be sure to consider what you have to weigh. If you have to weigh larger tanks, having a scale with a larger base and non-slip surface would be beneficial. Also, don’t be fooled. Just because a refrigerant weight scale is large doesn’t mean that it has the weight limit you’ll need.

What is the Construction Quality?
As is the case with most products, a refrigerant weight scale should be sturdy, durable, and rugged. While some scales are well-constructed, other scales may not be up to the standards that you need for the rigors of your daily routine. Water resistant, rubber feet and rubber padding are a few attributes to consider looking for when choosing a refrigerant weight scale.

How Easy is the Scale to Use?
Overall using a refrigerant weight scale is not difficult but there are things to consider for ease of use. Are the controls wireless? Does the scale run on batteries and if so, what is the battery life? Are platform measurements sent to both the remote display and a mobile app? Can you view units how you want? (pounds and ounces, pounds only, ounces only, kilograms and grams, kilograms only, or grams only).

Before you buy a refrigerant weight scale, make sure you ask yourself the five things listed above. They’ll help you find the right one you need.

Proper care and maintenance are significant in improving the structural integrity of your HVAC vacuum pump and extending their lifespan. However, there will be a time when even the best HVAC vacuum pump will need replacement, no matter how much care and maintenance you give it. Here are reasons to consider for when you should replace your vacuum pump.

Low or Inconsistent Vacuum
The most important indication for the proper function of a HVAC vacuum pump is its ability to reach its specified final pressure, or ultimate vacuum. A vacuum pump with low suction power will be unable to do its job correctly. If your vacuum pump has low suction power, try changing the oil. If after changing the oil, the pump is still unable to reach its ultimate vacuum, then that may be an indicator the vacuum pump needs to be replaced.

Overheating Vacuum Pump
An HVAC vacuum pump should not regularly overheat. If your vacuum pump overheats when operating or constantly shuts down because of overheating, you should consider replacing it. Replacing the vacuum pump will prevent heat-related damage and save you money on costly repairs.

Old Vacuum Pump
While HVAC vacuum pumps can be very durable, they will not last a lifetime if used regularly. An older HVAC vacuum pump is less efficient and more prone to damage. Additionally, there have been many advancements in technology and innovation that apply to HVAC vacuum pumps. Newer vacuum pumps offer even more reliability and speed. They are built to cut back evacuation time allowing you to get your work done more quickly. Depending on the age of your vacuum pump you may want to replace it.
