Ran into a system today where suction pressure looked low so it seemed like a charge issue at first, but after checking a bit more it turned out to be airflow again. Starting to feel like airflow gets overlooked way too often because gauges are just easier to rely on. Curious if anyone else finds themselves double-checking airflow more than they used to.

Bought a new vacuum pump thinking it would speed things up, but honestly not seeing much difference compared to my old one yet. Maybe I’m missing something, but as long as I’m pulling down properly and holding, it all feels the same on most jobs. Curious if anyone actually noticed a real upgrade going from a basic pump to a higher-end one.

Hey everyone, just heard the news about Mingledorff’s merging with The Home Depot. I’m curious what we think this means for us in the repair community. Has anyone noticed a shift in prices or quality after mergers like this in the past? Let’s reflect on whether industry consolidation genuinely affects us or if it’s just business as usual.… Read more

Finally picked up a micron gauge this week. Been in the trade 9 years and have been judging vacuum on the manifold needle the whole time like everybody else I learned from.
First job I used it on — thought I had a good vacuum. Manifold needle looked right. Micron gauge said 1,840. Nowhere near where it needed to be.
Should have got one of these years ago.

Not looking for the “commercial is way better” highlight reel. The real version.
What actually changed about the physical install the tools, the process, the rooftop conditions, the weight of everything you’re moving?

Nitrogen purge when brazing. Every time. No exceptions.
That’s what we’re taught and honestly that’s what I believe. But I’ve had this argument with enough experienced techs to know it’s not as black and white as the textbook makes it sound.
On a brand new install no question. Purge the whole time. Copper oxidation in a new system is a… Read more

Went out on a spring service call this week. Homeowner mentioned their heating bills were a lot higher than usual this winter but figured it was just the cold.
Hooked up the gauges. System was running in cooling mode. Full cooling mode. In the middle of winter.
Reversing valve stuck in the cooling position. Has probably been like that since… Read more

New RTUs just landed for a warehouse changeout. Three units going up on the roof later today. Always a bit of coordination getting the crane set, rigging right, and making sure the curb measurements actually match what was ordered. Nothing worse than getting everything up there and realizing something doesn’t line up. Long day ahead.

Just closed on a house built in the 1920s and the furnace looks pretty new installed around 2022 from what I can tell. While walking through everything I noticed a lot of the return vents are blocked off or covered up behind trim and built-ins. Not sure if that was done intentionally during renovations or just over time. Is there any legit… Read more

We charge a service/diagnostic to come out and troubleshoot. The only time we roll that into the total is when the customer decides to replace the system and signs off on the install. Otherwise the diagnostic stays separate, even if it turns into a decent sized repair.

Do any of you waive or apply that initial fee once the repair crosses… Read more

Found this inside the unit today insulation split open and the copper conductors exposed and fraying.
Not failed yet, but this is exactly how intermittent faults, nuisance trips, and random shutdowns start once vibration and heat do their thing.

Contact points are showing early signs of heat stress and wear. Pitting and discoloration suggest rising resistance, which can lead to voltage drop under load and intermittent sticking once the contactor warms up. This one’s heading toward failure not there yet, but close.
