That’s CO in somebody’s house right now.

In reply to - Grayson posted an update in the group Troubleshooting & Repairs Called out for a no heat. Found this. Customer said the other company was out last month and told them everything was fine.

Compressor needs refrigerant to keep it cool so it being hot at those pressures isn’t abnormal. I’d charge it up to get them AC again and recommend doing a leak search. Tell them refrigerant doesn’t come with a warranty. If they don’t do it and call you back this year or next year deny the work unless they find the leak and repair it first.

I stopped taking Friday evening calls entirely last summer and my mental health improved dramatically.

In reply to - Henry posted an update in the group HVAC Installation Best Practices Genuinely curious how you all handle the customer who calls at 4:55pm on a Friday saying their AC has been out since Wednesday.

Best way to repair a microchannel condenser coil that took some damage? Bent fins on about a 6 inch section, not leaking yet but it’s bad. Replacement is backordered 6 weeks.

Had a customer show me a screenshot mid diagnosis like it was a trump card. I just said cool, did ChatGPT also tell you the model number and the actual fault code, because I haven’t told you that yet. He got quiet.

Halfway through the year. Real talk time.

I’m not asking to judge. Most business owners set goals in January and never actually measure against them.

You can see where one contractor stopped, another picked up, and nobody coordinated. Controls here, duct changes there, piping rerouted with no plan. It all works, but it’s fragile.

Internal fiberglass insulation inside the unit has degraded and detached. The insulation has sagged into the airflow path, collecting dust and debris. This creates airflow restriction, increases static pressure, and allows insulation fibers to enter the airstream. At the same time, moisture exposure has caused surface corrosion on nearby… Read more
