    As a certified HVAC tech, I applaud the effort. However, all the little delays like not having the correct adapter to pressurize and evacuate the equipment and ordering the incorrect parts would have been eliminated and install would've been completed in 1 or 2 days depending on the size of the crew.

    The way he broke the cable armor made me cringe, it's a fire hazard if you do it that way. Breaking it by hand creates a burr on the inside of the armor. When it rubs against the wire insulation it cuts it over time, creating a hot spot, creating a fire. Brian should of known better, use a damn saw.

    I assume that being in Canada, running a condensate line though an attic could easily lead to a frozen condensate tube in the Winter time. Should I assume this attic is somewhat a conditioned space?

    It’s funny all the HVAC techs saying it hurt to watch this and spouting all the stuff he did wrong. What does it matter? It’s his shit. Let him do it wrong. If he wants he can have someone qualified repair it. Just seems like they want to brag about all the stuff they know and point out all the negatives. Could’ve been much much worse and no one gives a shit on RSloft what you know when you’ve been practicing and doing it for a long time when your criticizing someone who has little knowledge doing the job. Put your egos aside and let your humility take a turn. No one pointing out all the stuff he did right. Refrigeration and electric is tough stuff to work on.

    A carbon dioxide bottle in the intro? Youre using a Carbon Dioxide A/C?! Some of the newer supermarkets are using CO2 as the refrigerant. Its really cheap. The only problem is that it operates at high pressures (1200psi for CO2 vs 250psi for standard Freon refrigerant) and if you have a leak, the Liquid CO2 can have a phase change directly to Dry Ice!!! So you can instantly turn your liquid CO2 into dry ice, inside your AC's pipes, Anti-Bueno.

    Wow and y'all even cut into a fucking vent to put unmetered water into your sewer or septic. Brian the electrician shouldn't be doing HVAC also I never saw him purging Nitrogen when he was brazing. So congratulation on contaminating the system by your incompetence

  • Lensflair

    How long did it take the municipality to grant the permits for this project? And did the city electrical and plumbing inspectors want to see the install before you replaced the insulation? Assuming that’s your side yard, I’m also surprised they approved the location of the condenser unit so close to the property line.

    I installed my own in 2018. This included a legal electrical cutoff. It only took a weekend. If you are an advanced diy person and have everything ready, it's not that hard. I did need to buy a vacuum pump to charge it up as well.
