You walk in thinking it’s a quick job and next thing you know you’re chasing a second issue. Happens more than I’d like to admit. You guys run into this a lot or just bad luck days?

Different expectations, different standards.

In reply to - Jameson posted an update in the group HVAC Installation Best Practices Do you pull to 300 microns or 500 microns on a residential install and has it ever actually made a difference in the real world? ]]> c8d0fc0f05031a2a111f1e9e628293ef Cameron posted a new activity comment https://hvachub.co/news-feed/p/6419/#acomment-6439 Sat, 21 Mar 2026 08:46:22 +1300 This is a checklist item now on every single one of my installs.

In reply to - Owen posted an update in the group HVAC Tools & Equipment Can I install a zoning controller on an older single-duct system without upgrading the dampers?

You’ll damage the compressor for sure.
