How to Lower Your Heating Bill in a Cold Utah Winter

Winter heating bills in Utah County can jump fast once the overnight lows settle into the teens and twenties. The good news is that most of the biggest savings come from small, cheap changes you can make yourself — not from buying anything new. Here's an honest rundown of what actually moves the needle, roughly in order of bang for your buck.

Start with your thermostat settings

The single cheapest change is also the most effective: turn the heat down when you don't need it. Every degree you lower your thermostat over a long stretch saves energy, and the savings add up over a full Utah winter.

A reasonable approach for most homes is 68°F when you're awake and home, and 60–62°F while you're asleep or away for the day. If anyone in the house is elderly, very young, or has health concerns, adjust for comfort — this isn't worth suffering over.

What you want to avoid is the habit of cranking the thermostat to 75 to "heat the house faster." Your furnace puts out heat at the same rate regardless; you'll just overshoot and waste gas. If your schedule is consistent, a programmable or smart thermostat makes these setbacks automatic so you're not relying on memory.

Seal the drafts you can feel

Utah's cold, dry winter air finds every gap in your house. On a windy day, walk around with your hand near windows, exterior doors, outlets on exterior walls, and the attic hatch. Where you feel cold air moving, you're losing heated air.

The fixes are inexpensive:

• Weatherstripping around doors and windows that leak
• A door sweep on exterior doors with a visible gap at the bottom
• Caulk around window trim and where pipes or wires enter the house
• Outlet gaskets for exterior-wall outlets (a surprisingly common leak)

A weekend and $50 in materials often tightens up a home noticeably. Older homes in American Fork, Orem, and the established parts of Lehi tend to have the most to gain here.

Add attic insulation if yours is thin

Heat rises, and in a lot of Utah County homes — especially anything built before the mid-1990s — the attic simply doesn't have enough insulation. If you can see the tops of your ceiling joists poking through the insulation, you're under-insulated.

More insulation up top keeps heat in your living space longer, so your furnace runs less. It's a bigger project than weatherstripping, but it pays back steadily winter after winter, and it helps in summer too.

Use the sun and your window coverings

This one is free. On clear days — and Utah gets plenty of winter sun — open the curtains and blinds on south- and west-facing windows to let solar heat in. As soon as the sun drops behind the mountains, close them to trap that warmth and add a layer against the cold glass. Insulated or heavier curtains do more than thin ones.

Keep air moving — the right way

Most ceiling fans have a winter setting that reverses the blades to spin clockwise at low speed. This pulls cool air up and pushes the warm air that's pooled near the ceiling back down along the walls. In rooms with high or vaulted ceilings, it makes a real difference without touching the thermostat.

Also make sure your supply and return vents aren't blocked by furniture, rugs, or boxes. Restricted airflow makes your system work harder and heat unevenly. If some rooms never get warm no matter what, that's often an airflow or balancing issue — we cover the common causes in why some rooms are hotter or colder than others.

Don't skip the furnace filter

A clogged filter chokes airflow, forces your furnace to run longer, and can even cause it to overheat and shut down. During heating season, check your filter monthly and replace it when it looks gray and loaded. Utah's dust — plus construction in the fast-growing parts of the county — tends to load filters faster than the box's "90 day" rating suggests. Our filter guide breaks down how often to change which type.

Make sure the furnace itself is running efficiently

A furnace that's dirty, out of tune, or not quite working right burns more fuel for less heat. A few things to watch for:

• Short cycling — the furnace turning on and off every few minutes instead of running steady cycles. It wastes energy and signals a problem worth diagnosing.
• Cold or weak airflow from the vents even when the burner is lit.
• Rising bills with no change in the weather or your habits.

An annual tune-up keeps the burners clean, checks the heat exchanger, and confirms everything is firing efficiently. If you've been putting it off, our furnace winter-prep checklist walks through what should get done, and regular maintenance is the simplest way to keep an older furnace from quietly costing you more each month.

Lower your water heating costs too

Water heating is usually the second-largest energy user in a home after heating and cooling. Two easy wins: set your water heater to around 120°F (many are shipped hotter than needed), and insulate the first few feet of exposed hot-water pipe. If your water heater is old and showing its age, be aware that a failing unit also runs less efficiently — here are the signs a water heater is about to fail.

When an upgrade actually pays off

Sometimes the math points to replacement rather than nickel-and-diming an old system. If your furnace is 15–20+ years old, needs frequent repairs, or is a low-efficiency model, a high-efficiency furnace can cut your gas use meaningfully. It's a real expense, so it's worth running the numbers honestly — our guide on repairing versus replacing a furnace can help you decide, and if you're worried about the upfront cost, there are financing options that spread it out.

The point isn't to upgrade for the sake of it. For most homeowners, a combination of thermostat discipline, draft sealing, a clean filter, and a well-maintained furnace is enough to bring a winter bill back down to where it should be.

A simple winter savings checklist

• Set thermostat to 68°F awake, 60–62°F asleep/away
• Weatherstrip and caulk obvious drafts
• Open south-facing curtains on sunny days, close them at dusk
• Reverse ceiling fans to clockwise on low
• Check the furnace filter monthly
• Clear furniture away from vents
• Turn the water heater down to about 120°F
• Book a furnace tune-up if it's been over a year

If your heating bill still seems high after working through this list, something in the system is likely working harder than it should. We're glad to take a look — reach out for a quote or learn more about our team serving Lehi and the rest of northern Utah County.
