Your First Winter in This House: What to Check, Book and Keep Track Of

For your first winter in a new house, check the heating equipment and its filter, test every smoke and carbon monoxide alarm, watch where water goes during rain, and find your shut-offs. Split what is left into what you can do yourself, following the manufacturer instructions, and what you need to book. Write it down.

A long seasonal checklist makes every task look equally urgent. It is not. In a house you have only just met, most of the value this season comes from three things: making sure nothing unsafe is being ignored, finding out what your equipment actually is, and starting a record so next year begins from facts instead of guesses.

Check yourself: the short list

Find the heating equipment and read its label. Note the make, model, serial number and filter size, and look for a service sticker with a date. Inspect the filter and clean or replace it as the equipment and filter manufacturer directs. Do not assume a high-resistance filter suits your system — the manual decides that, not the packaging.

Test smoke alarms monthly and check the manufacture date printed on each one. USFA advises replacing smoke alarms after ten years; follow the device instructions for faults and sealed-battery units. Check carbon monoxide alarms separately, using their own instructions. A smoke-only alarm does not detect carbon monoxide. If a CO alarm sounds, get everyone outside and call emergency services rather than treating it as a maintenance task.

Walk the outside of the house at ground level while it is raining, and again afterwards. Photograph gutter overflow, downspouts discharging against the foundation, fresh interior staining or standing water. A dated photo is a baseline, not a diagnosis. Find and label the main water shut-off, the heating equipment switch and the electrical panel while nothing is going wrong.

Your climate decides half this list

Freeze tasks and warm-climate tasks are not the same work, and doing the wrong set wastes the season.

Book it: what is worth a professional this season

ENERGY STAR recommends a professional pre-season heating check. An unknown service history is a good reason to book one before cold weather rather than after. Book, rather than attempt, anything involving gas, flues, roof access in wet conditions, hardwired electrical work, or a system you cannot identify.

When you call, ask what the visit includes, what they found, and what they would want to look at again. Ask for it in writing. Two quotes only compare when they describe the same work. Use HomeScore's system cost guides to frame the questions, then confirm labor, permits and equipment choices locally — a published planning range cannot tell you what this specific job costs where you live.

Keep track: a one-page seasonal record

Keep one page per season, and fill in the record further down this page as you go. Add the model numbers and filter sizes you found, and mark anything you do not know as unknown. Unknown is a more useful entry than a guess — and far more useful than treating the age of the house as the age of every system in it.

Age alone does not establish a replacement deadline. Condition, service history and manufacturer guidance do. Your record is what turns next winter from a repeat of this one into a shorter, better-aimed list. Connect it to your first-year homeowner plan, and use the maintenance schedule by house age for questions, not verdicts.
