Things They Should Invent: user manuals for new homes

For most of the first-time homeowners I know, their first major expense was the result of being unaware of a kind of preventive maintenance that was required.

Solution: whenever a builder builds a new home, they should provide a manual listing all the preventive maintenance that's necessary, how often it needs to be done, and how, exactly, to do it.

 At this point, people usually point me at the Tarion checklists, but they're close to useless if you're a newbie.  For example, the first item in the fall checklist is "check exterior finishes".  What exactly is an exterior finish?  How do you check it? Do you just look at it, or is some kind of testing procedure required?  What exactly are you testing it for?  And if you find a problem, how do you go about fixing it?  (Also, what's the timeline like to fix it?  Do you have to fix it right away or can you wait a day/week/month?)  And is this even something that applies to my condo, or is just it for house people?

I want detail, in writing and with useful illustrations.  As an example, simplified from reality (and therefore possibly not perfectly accurate):

HVAC filter

There's a filter on your HVAC system that needs to be changed once a year to keep your HVAC system running smoothly.

1. The HVAC filter can be found inside this access panel. [illustration]
2. Open the panel by pulling on the left side, as shown. [illustration]
3. The filter is below the access panel. If you look down, you can see the top edge of the filter. Remove it by pulling it upwards, as shown. [illustration]
4. If the filter is visibly dirty, replace it. Replacement filters can be purchased from [source] under part number [number].
5. Insert the new filter by sliding it back down into the bottom of the access panel, in the direction shown [illustration].

Builders should provide instructions at this level of simplicity and clarity for every single kind of maintenance for which homeowners are responsible.  This would significantly reduce the expense and inconvenience of unnecessary emergency repairs, thereby making homeowners feel better about their builder.

Since many of the elements in the maintenance manual will be identical for every home built, and since builders tend to construct homes en masse (either with highrise condos or new subdivisions), the cost per home would be negligible and could easily be passed on to buyers without them even noticing. And since builders likely reuse elements in different projects (for example, my builder has multiple highrise projects in progress as we speak, each with multiple hundreds of units, so I doubt they're going to use a completely different HVAC in each) they could spread out the cost even further.

At this point, some people are probably thinking "But once you get used to being a homeowner, you don't need a manual. You know how things work! That's a lot of effort for something that's just needed by beginners!" 
But think about how many things do come with manuals. Microwaves and phones and TVs and office chairs and alarm clocks and wrinkle cream and frying pans all come with instructions.  So why doesn't the biggest purchase we ever make, which affects every aspect of our life every single day?

If it turns out the manual contains information that's new to you, it's a lifesaver!  And if it doesn't, you just tuck it away in a drawer somewhere like you do with the manual for your coffeemaker or your ceiling fan, and maybe when it comes time to sell your home, the next owner will think it's a lifesaver.
