Speed just exposes it.

In reply to - Samuel posted an update in the group HVAC Installation Best Practices Callbacks are killing time over small misses lately. Anyone else dealing with this? ]]> cae3d8b56a3676d33ebb6584a2e44c2a Fabio posted an update in the group Troubleshooting & Repairs: Thinking about outsourcing SEO/marketing but hard to […] https://hvachub.co/news-feed/p/6538/ Tue, 07 Apr 2026 21:06:00 +1200 Thinking about outsourcing SEO/marketing but hard to tell who actually delivers vs who just sends reports every month. Anyone here had a good experience with a company?

In reply to - Alessandro posted an update in the group Troubleshooting & Repairs Hey folks, ever hit up a service call with a complaint of no cooling, only to find the system running fine?

Seen a TXV fail from contamination exactly once in 12 years and it was from a full evap coil replacement with zero purge. Not a 90 second repair.

Then suddenly it’s the most important thing in the world.

As long as it goes into defrost you’re probably fine.

If you jump straight into parts or adjustments you end up chasing symptoms instead of the cause.

Cold start numbers look decent, then once it’s been running a bit everything starts chasing itself. Watching the valves now to see if one starts drifting under load.

Supply temp swings after runtime, heat transfer isn’t steady, and it never really settles. Refrigerant side looks okay, airflow is there, but the response doesn’t line up with the actual load.

I had a similar situation last week where a homeowner wanted to improve their VOC levels without breaking the bank. Ended up recommending a DCV system since it helps manage airflow without going over budget, and they really liked that. Balancing cost and performance can be a headache,… Read more
