In reply to - Tristan posted an update in the group Troubleshooting & Repairs Bought a new vacuum pump thinking it would speed things up, but honestly not seeing much difference compared to my old one yet.

I’ve had a couple boards let it creep on and it kills heat input.

First year is about learning how to think, not how to rush. Pay attention to airflow, wiring basics, and why things fail – not just how to swap parts. The best techs I know were slow early on but asked a lot of questions.

In reply to - Zachary posted an update in the group HVAC Contractors & Subcontractors Starting out in HVAC and realizing how much there is to learn – any advice from the field? ]]> 0686b35fbf584a91726f3e1710abf723 Antonio posted a new activity comment https://hvachub.co/news-feed/p/3624/#acomment-3631 Mon, 15 Dec 2025 09:44:55 +1300 Perfect temperature, swamp-level humidity – classic comfort combo.

In reply to - Cameron posted an update in the group HVAC Contractors & Subcontractors Got a strange one today: several thermistors are drifting 5–7°F again right after calibration. ]]> c3eb7dd19441cfed8f452ce7ee3312e1 Antonio posted a new activity comment https://hvachub.co/news-feed/p/3045/#acomment-3052 Fri, 14 Nov 2025 19:20:54 +1300 Could be your PID loop too tight. If proportional is high or integral is slow, the AHU will “chase” static instead of holding it.

In reply to - Dylan posted an update in the group HVAC Installation Best Practices Was checking a VAV system today and the static pressure kept jumping all over the place- from 0.9” straight up to 1.6” the moment a few […] ]]> ef85496c61b1a561c8092bde7ad2e6b0 Antonio posted a new activity comment https://hvachub.co/news-feed/p/2970/#acomment-2983 Wed, 12 Nov 2025 19:59:18 +1300 Give it time – they’ll all quit together eventually.

Measure voltage right at the motor next time.

Check the equalization line.

That’s why monitoring tools make such a big difference-they catch patterns humans miss.

That’s why educating clients upfront is just as important as installation.

That’s where hidden costs creep in.

A poorly configured BMS can neutralize the efficiency of even the best equipment. Regular fine-tuning is critical.

The issue often isn’t the equipment itself, but factors like improper load calculation, poor BMS integration, or controls that were never fine-tuned.
