  • Not an expert but these systems are fairly self-contained and robust. A few things that can be checked easily is that the fan spins, the radiator is free of debris and some compressors might have a sight glass for the oil level.

    Any other checks regarding performance of the system, leaks and refrigerant level require you to perform a full refrigerant discharge and recharge. That takes special equipment and some time so no one in their right mind would do that for free, unless they can then force/guide you into some kind of upsell situation.

    Larger systems might have some kind of oil filter/catch-can that you might be able to check easily but I’m not too sure on that.

    After all heat pumps are just plain old A/C units with a reversible cycle.

    You can use their online web-editor (similar to OverLeaf for LaTeX) or download the open-source engine and run it locally (there are extensions available for many text editors).

    Compared to LaTeX I find it much more comfortable to work with. It comes with sane, modern defaults and doesn’t need any plugins just to generate a (localized) bibliography or include links.

    Since Typst is very young compared to LaTeX I’m sure that there are numerous docs / workflows that can’t be reproduced at the moment but if you don’t need some special feature I’d recommend giving it a shot.

    The “add to home screen” button turns into an “install” button when Firefox detects that the website is a progressive web app (PWA). Other browsers do the same.

    The difference is that a PWA can define a custom icon and name for the “app” button on your home screen and that it can use some clever caching making many PWAs offline capable (meaning you don’t need an internet connection to open the web page).

    I understand the reluctance to press “install” but in the case of PWAs the install size is tiny and fully contained in Firefox and you get the added benefit of faster startup / loading times due to caching.
