What Temperature Should I Set My Thermostat in Winter?

Oklahoma’s first real cold front never gives much warning. One week you’ve still got the AC running in the afternoon, and the next you’re reaching for the thermostat wondering what number actually makes sense now that you’re paying to make heat instead of remove it. A common call we get this time of year isn’t a breakdown at all — it’s a homeowner asking what they should be setting the thermostat to before the heating bills start climbing.

There’s no single magic number, but there is a sensible range and a few settings that quietly cost people money all winter. Here’s how to think about it.

A reasonable starting point

For most Oklahoma homes, 68°F while you’re awake and home is a solid baseline. It’s warm enough to be comfortable in a sweater, and it keeps the furnace from running more than it needs to.

That said, “comfortable” is personal. A house full of kids and pets feels different from a quiet home for two. The useful rule of thumb: the best setting is the lowest temperature your household is genuinely comfortable at. Every degree lower means your furnace runs a little less, and over a full Oklahoma winter that adds up. If 68 feels chilly, nudge it to 70 — just know that each degree up is a little more runtime and a little more on the bill.

Turn it down when you’re asleep or away

This is where the real savings live. There’s no reason to heat an empty house or a bedroom full of people buried under blankets to the same temperature you’d want while sitting on the couch.

Dropping the thermostat 7 to 10 degrees for the roughly eight hours you’re at work, and again overnight, is a well-established way to cut heating energy without sacrificing comfort when it counts. Your house cools slowly, and warming it back up costs less than holding it high the whole time — because a warmer house loses heat to the cold outside faster than a cooler one does.

A programmable or smart thermostat makes this effortless: set it to drop while you’re gone and asleep, and to warm back up shortly before you wake or get home, so you never actually feel the setback.

The heat pump exception

If your home runs on a heat pump rather than a gas furnace, the advice changes in one important way: don’t make big manual temperature swings.

Heat pumps heat gently and steadily. When you crank the thermostat up several degrees at once, the system often can’t recover fast enough on its own, so it kicks on the electric backup (or “auxiliary”) heat — which is far more expensive to run. Do that every morning and you can wipe out any savings the setback earned overnight.

The fix isn’t to give up setbacks entirely; it’s to keep them smaller, or use a thermostat with a true heat-pump mode that recovers the temperature intelligently instead of slamming on the backup heat. If you’re not sure which type of system you have, it’s worth knowing before winter — the outdoor unit running on a cold day is a giveaway you’ve got a heat pump. (Our piece on emergency heat is a good companion read if you’ve ever seen “Aux” or “Em Heat” pop up on your thermostat.)

Comfort isn’t only about the number

Two homes set to the same 68°F can feel completely different, and it’s usually not the thermostat’s fault:

• Dry winter air feels colder. Oklahoma winter air is dry, and dry air pulls heat off your skin faster, so a properly humidified home can feel comfortable a degree or two lower.
• Drafts and cold spots make a room feel colder than the thermostat reads. Sealing obvious drafts and closing blinds at night helps the whole house hold its heat.
• Where your thermostat lives matters. If it’s on a drafty wall or near a supply vent, it may be reading a temperature the rest of the house doesn’t share, and short-cycling your furnace in the process.

If you’re constantly bumping the temperature up because certain rooms never feel warm, the problem is more likely airflow, insulation, or a struggling system than the setting itself — and pushing the thermostat higher just runs the furnace harder to mask it.

When the setting isn’t the problem

If you’ve landed on a reasonable number and the house still can’t hit it — the furnace runs and runs but never satisfies the thermostat, or some rooms stay cold no matter what — that’s a sign to look at the equipment rather than the dial. Weak heat, uneven rooms, and constant runtime often trace back to a dirty filter, low airflow, duct losses, or a furnace that’s overdue for a tune-up before the coldest weather hits. Our furnace repair team can pin down why the heat isn’t keeping up, and a fall check-up is a lot cheaper than a no-heat call on the first freezing night.

The bottom line

Start around 68°F when you’re home and awake, drop it 7–10 degrees while you’re asleep or away, and let a programmable thermostat do the switching for you. If you have a heat pump, keep the swings smaller so you don’t trigger the pricey backup heat. And if a comfortable setting suddenly can’t keep the house warm, treat that as the furnace asking for attention — not a reason to keep nudging the number up.
