HVAC Vacuum Pump Down: Hold Test and Charging

by | Apr 1, 2024 | HVAC Technical Academy, HVAC Technician, HVAC Training, Universal 608 EPA

HVAC Tech in SIX WeeksHappy April first! This term is flying by and we are only five weeks until the next HVAC 6-weekshop to begin and get you in an HVAC career FAST! The first three weeks have been exciting as our group of has been getting busy troubleshooting, installing, diagnosing, and getting deep into HVAC systems. With that, let’s get back to our vacuum pump.

Vacuum Evacuation and Monitoring

Hold Test: After reaching the desired vacuum level, technicians perform a hold test to confirm system integrity. During the hold test, the vacuum pump is turned off, and the system is isolated from the pump. Technicians monitor the vacuum level over a specified period to ensure it remains stable, indicating the system is airtight and free of leaks.

Charging: Once the evacuation and hold test are completed successfully, the HVAC system is ready to be charged with refrigerant. Technicians introduce refrigerant into the system using appropriate charging methods, such as liquid or vapor charging, to achieve the desired refrigerant charge level.

During our 6-week workshops you will learn the proper strategies to pump down systems as we develop YOUR HVAC Clarity, Choice, Confidence, and Competence.

Interested in a career in the HVAC industry, consider HVAC Technical Academy to help you get on the path quickly and effectively. Looking forward to hearing from you!

HVAC Vacuum Pump Down: Evacuation and Monitoring

HVAC Vacuum Pump Down: Evacuation and Monitoring

by | Mar 29, 2024 | HVAC Program, HVAC Technical Academy, HVAC Training, Universal 608 EPA

HVAC Learning in ActionThe past few weeks have been exciting as our recent group of HVAC workshop participants have been installing systems, rebuilding, recovering, troubleshooting, and much more. With that, let’s get back to our vacuum pump down in detail.

Vacuum Evacuation and Monitoring

Evacuation: Once the system is prepared, technicians turn on the vacuum pump to start the evacuation process. The vacuum pump removes air and moisture from the system by creating a negative pressure environment, causing the trapped gases and moisture to be expelled through the pump’s exhaust.

Monitoring: Technicians monitor the vacuum level using vacuum gauges or digital vacuum meters throughout the evacuation process. The goal is to achieve and maintain a deep vacuum, typically below 500 microns, for a specified period. This ensures that the system is thoroughly evacuated, and the risk of moisture and air contamination is minimized..

During our 6-week workshops you will learn the proper strategies to pump down systems as we develop YOUR HVAC Clarity, Choice, Confidence, and Competence.

HVAC Vacuum Pump Down

HVAC Vacuum Pump Down

by | Mar 1, 2024 | HVAC Technical Academy, HVAC Training, Universal 608 EPA

HVAC ALL the wayA new month means a new HVAC topic you gotta know: Vacuum Pump Down.

During the next few weeks we will break the topic down into easy-to-follow steps. For those interested in HVAC as a career, vacuum pump downs and so much more are a daily hands-on experience at HVAC Technical Academy.

What’s it all about

HVAC vacuum pump down is a crucial step in the installation, maintenance, or repair of HVAC systems, particularly during the evacuation process when removing air and moisture from refrigerant lines and components.

Purpose: The primary purpose of vacuum pump down is to remove air and moisture from the HVAC system’s refrigerant lines, coils, and components. Air and moisture can degrade system performance, cause corrosion, and lead to compressor failure if not properly evacuated.

During our six-week HVAC Workshop program, you will become very comfortable in pumping down systems as well as much more each day by DOING!

Braze: Cooling and Safety

Braze: Cooling and Safety

by | Jan 29, 2024 | HVAC Technical Academy, HVAC Training, Universal 608 EPA

Braze: Mark in ActionLet’s conclude the brazing process and DO NOT forget about safety!

Braze: Cooling and Safety

Cooling: After the brazing alloy has solidified and formed a strong bond between the components, the assembly is allowed to cool.

Safety: Let’s not forget about safety as the flames are hot. When brazing ensure you have a small pale filled with water and a rag just in case it is needed. Upon brazing completion, remember the pipes are hot so do not grab immediately, place water and rag on the line as well. In addition, make sure you keep the torch away from your flesh, clothes, or objects nearby.

Conclusion: HVAC brazing is commonly used for connecting copper tubing and fittings in air conditioning and refrigeration systems. It ensures a reliable and leak-free connection, essential for the efficient operation of HVAC systems.

We’ll continue next time and review characteristics employers are looking for when it comes to becoming an excellent employee and HVAC Technician.

If you have any questions or topics of interest, please let me know. For those considering a career in the HVAC industry, let’s talk as our 6-week intensive workshops can get you there fast.
