Your First Winter in the House: Five Questions About the Heating System and Your Policy

The first cold night in a new house is the first time you find out whether the furnace works, how old it is, and what your insurer assumes about it. Heating equipment is the second leading cause of home fires in the U.S., behind cooking, according to the National Fire Protection Association (NFPA). It is also the system new owners know least about, because nobody hands you its history at closing.

Five questions will get you ready before the first freeze. Answer them now and you will walk into renewal, and into any claim conversation, with facts instead of guesses.

Find the age and service date of what's heating your home

Start with the label. On a furnace or boiler, open the access panel or look on the side of the cabinet for a data plate. It lists the make, model, and serial number. The serial number usually encodes the manufacture date, and a quick search of the brand plus "serial number age" will decode it. Photograph the plate, and photograph the whole unit.

Most gas furnaces last 15 to 20 years, according to major manufacturers. Electric furnaces often last longer. If yours is past 15, that is not an emergency, but it changes how you plan.

Here's what most people don't know: the inspection report from your purchase is rarely a service record. It says the system ran on the day of the inspection. It does not say when a technician last cleaned it, replaced the igniter, or checked the heat exchanger. Ask the seller for service invoices. If they have none, book a tune-up this month and keep the invoice. That one piece of paper becomes your starting record.

What the renewal questionnaire asks about heating

Carriers price what they are shown, and heating is a common question on applications and renewal forms. Expect to be asked the type of primary heat, the age of the system, whether you have a wood stove, fireplace insert, or other solid-fuel appliance, and whether a professional installed it. Some forms also ask when the system was last serviced.

These are not trick questions. They are the carrier's way of sizing fire and carbon monoxide risk on a house it has never walked through. The gap is informational. If you do not know your furnace's age, you either guess or leave the answer blank, and neither helps you.

Answer from a record. If the form asks for a year and you only have a range, give the range and say how you got it. An honest "installed around 2009, serial number decoded" beats a confident wrong year. A wrong answer on a form can come back during a claim.

Space heaters and supplemental heat: what to disclose

Space heaters are the part of home heating that causes the most harm. NFPA analyses have found that space heaters are involved in a minority of heating fires but a large majority of heating-fire deaths. The usual causes are simple: the heater sits too close to furniture, bedding, or curtains, or it runs unattended.

Three rules cover most of the risk. Keep anything that burns at least three feet away. Plug the heater directly into a wall outlet, not an extension cord or power strip. Turn it off when you leave the room or go to bed.

On disclosure, read your application and your policy. If a form asks about supplemental heating, a wood stove, or a fireplace insert, answer it. If you add a wood stove or pellet stove after you move in, tell your agent before you light it, not after. Some policies require professional installation or a permit for solid-fuel appliances, and finding that out after a fire is the wrong time.

What a service record changes in a claim conversation

After a heating-related loss, an adjuster has questions: how old the equipment was, who installed it, and whether it was maintained. Without records, every answer starts with "I think." With records, the conversation is short and factual.

A dated service invoice does not guarantee a claim is paid, and it is not a coverage term. It does something more practical. It shows the loss was not a case of neglect, it speeds up the carrier's review, and it protects you if the question of maintenance ever comes up.

Keep four things together: the equipment photo with the data plate, the install or purchase date, each service invoice, and any repair receipts. Store them somewhere you can reach from your phone, because the day you need them, the paperwork in the basement may be the part of the house that is damaged.

Carbon monoxide and smoke alarm basics

Furnaces, boilers, water heaters, and stoves all produce carbon monoxide when something goes wrong. Install a CO alarm on every level of the home and outside each sleeping area. Test alarms monthly. Replace the entire unit after 5 to 7 years, because the sensor wears out even when the battery is fresh. The manufacture date is printed on the back.

Smoke alarms follow the same logic. Check the date on the back, and replace any alarm that is ten years old or older. In a house you just bought, assume nothing about the age of the alarms the previous owner left behind.

Many carriers ask whether you have working smoke and CO alarms, and some offer credits for monitored systems. A photo of each alarm, taken with the date visible, costs you two minutes and gives you proof later.

A 20-minute walkthrough before the first cold snap

Do this on a weekend morning with your phone in hand.

• Furnace or boiler: photograph the data plate and the whole unit. Replace the air filter. Write down the filter size.
• Service: if there is no invoice from the last 12 months, book a tune-up and ask the technician to note the system's age on the invoice.
• Chimney or flue: if you have a fireplace or stove, schedule a sweep and inspection before first use.
• Alarms: test every smoke and CO alarm, and note any that are past their replacement date.
• Space heaters: clear three feet around each one, and plug into the wall only.
• Records: put every photo and invoice in one folder with the date.

That is the checklist. The harder part is keeping it current: service dates slip, invoices get lost, and a year from now you will be filling out the renewal form from memory.

This is the problem Rafter's assessment is built to solve. A Rafter assessment records the age, condition, and service dates of your heating equipment, along with your alarms and other protective devices, and builds a prioritized mitigation plan so the first-winter fixes get done in the right order. Your records live in one dated file, so when the renewal questionnaire asks about heating, you answer from a record, and when a device qualifies you for a discount, you have the documentation to request it. Start your Rafter assessment at rafterhome.com this week, before the first cold snap, and walk into winter with the file already built.
