Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
Always use a calibrated torque wrench and follow specifications exactly.
Incorrect Torque Sequence
Tightening bolts in the wrong order can cause uneven pressure distribution and potential leaks or damage.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Clean and inspect all threads before assembly. Use new thread locker if specified.
Reusing TTY Bolts
Torque-to-yield bolts are designed to stretch and must not be reused.
Always replace TTY bolts with new ones. They are single-use only.
Dry vs. Lubricated
Not accounting for whether torque specs are for dry or lubricated fasteners can lead to incorrect tension.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 Why are torque specifications important for HVAC components?
Why are torque specifications important for HVAC components?
Incorrect torque settings can lead to premature failure of fasteners, potentially damaging the HVAC system. Over-torquing can strip the threads or deform the component, while under-torquing can lead to loose connections, leaks, and reduced system efficiency. For example, a loose AC compressor mounting bolt could allow the compressor to vibrate, causing excessive wear and potential failure. Proper torque ensures a secure, reliable connection, extending the life of the HVAC system and preventing costly repairs.
Q2 What should I do if I suspect a loose HVAC component?
What should I do if I suspect a loose HVAC component?
If you suspect a loose connection, such as a loose hose clamp or a loose bolt on a component, do not attempt to operate the HVAC system. Immediately address the issue by consulting these specifications and using the correct tools for tightening. Improper tightening can lead to significant damage to the system.
Q3 How can I ensure accurate torque application?
How can I ensure accurate torque application?
Use a calibrated torque wrench. Different types of fasteners require different torque values, and the torque wrench's accuracy is essential. Ensure the torque wrench is properly calibrated and in good working order. Apply the torque evenly, and avoid using excessive force, which can damage the threads or fasteners.
Q4 What if I don't have a torque wrench?
What if I don't have a torque wrench?
If a torque wrench is unavailable, use the next best alternative, which is a calibrated wrench with a similar size and shape. However, be exceptionally cautious as improper tightening can be more damaging than no tightening. If you are unable to safely and accurately tighten the components, seek professional assistance from a qualified mechanic.
Q5 What are the typical HVAC components that require torqueing?
What are the typical HVAC components that require torqueing?
Various HVAC components require torqueing, including hose clamps, compressor mounting bolts, condenser fan motor mounting bolts, and various ductwork connections. Refer to the specific specifications for each component for proper torque values.
