The Small Checks I Make Before the Heat Comes On

October 1, 2026

Before the heat comes on for the season, I like to make a few small checks while the house is still between routines. This is not a call to take apart an appliance or diagnose a system you are not qualified to touch. It is a quiet look at the things a household can see.

Start with the filter

Check the filter size and condition, then replace it if it is dirty or overdue according to the equipment instructions. If you rent, this is a good moment to find out whether the filter is your responsibility or belongs on the maintenance list.

Look at the vents

Make sure supply and return vents are not blocked by furniture, baskets, or a layer of dust. You do not need to rearrange the whole room. Clear the path so the system can do its ordinary work.

Notice what changed

Turn the system on only when you are ready to be home and attentive to it. Notice unusual smells, sounds, weak airflow, or anything that seems different from last year. Those are reasons to consult the manufacturer, landlord, or a qualified technician, not invitations to improvise a repair.

A ten-minute look now is one of the simplest ways to begin the heating season with better information.

While you are looking, check that smoke and carbon-monoxide alarms are present and within their recommended replacement or testing schedule. Look at the area around the equipment for anything stored too close, but do not move service panels or attempt combustion, electrical, or duct repairs. A clear list of observations gives a landlord or technician something useful to act on.

Keep the result of the check somewhere you can find it: filter size, replacement date, unusual sounds, and the name of the person or service to contact. If the system does not start normally, turn it off and seek qualified help. A seasonal check is valuable because it catches information early; it is not a substitute for inspection, cleaning, or repair when the equipment calls for those services.

With care,
