Heating and cooling
Keep the air moving through the system
The single most common fault we find in older houses is a filter that has not been changed in a year or more. A clogged filter restricts airflow, the system runs longer and harder for the same heat, and the utility bill quietly climbs. It also makes the fan louder, which is usually the point at which people notice something is wrong.
Write the filter sizes on the inside of the filter housing door with a marker pen. Then set a reminder for the first weekend of every month, on the first weekend of every season. It costs a few minutes and it removes the single biggest cause of short-cycling we see.
Water
Know where your isolation valves are
Take five minutes now to find the main water shut-off valve for the house and the isolation valves under every sink, behind every toilet and in the shower niche. Photograph them and put the photos on your phone, or better still, in a printed sheet somewhere sensible.
Then check that they actually turn. A quarter-turn valve that has seized for ten years will not move when you need it, and you will find that out at the worst possible moment. A few drops of penetrating oil and a gentle test every year or so keeps them free.
Knowing where the valves are turns a catastrophe into an inconvenience, and HEART AND DAGGER SOUTHERN LTD would much rather talk you out of a midnight call than take one.
Surfaces
Stop using the wrong cloth on the right surface
A microfibre cloth that has been used on a bathroom floor and then goes onto a finished tabletop will not damage anything, but it will not do a good job either. The real risk is the opposite habit: a damp kitchen sponge used on a lacquered cabinet leaves a dull film that takes an afternoon to remove.
Keep two cloths and one spray bottle, one for wet jobs and one for dry and finished surfaces. Keep a separate sponge for the kitchen sink. It is not a glamorous tip, but it is the difference between a surface that keeps its finish and one that needs re-finishing every two years.
Wood
Dust with the grain, and never in circles
Circular motions push grit into the open pores of an oiled surface and leave a fine swirl that catches the light. Straight strokes along the grain lift the dust instead of grinding it in.
Coasters, trivets and felt pads under vases are worth more than any product. A ring mark is nearly impossible to remove completely; a ring that never forms is a solved problem.
Plants
Check the soil, not the calendar
Push a finger two centimetres into the top of the pot. If it feels dry at that depth, water. If it feels damp, wait. This single habit prevents the majority of plant deaths we are called to look at, and it takes five seconds.
When you do water, do it slowly until it runs out of the drainage holes, then empty the saucer after ten minutes. A pot standing in water is a pot with rotting roots, and no amount of light will fix it.
