How to Lower Your Utility Bills, Season by Season

Utility bills have a way of sneaking up on you. One month feels manageable, then a heat wave or a cold snap arrives and the next bill is noticeably higher. The good news is that a lot of what drives those bills is within your reach, and many helpful changes cost little or nothing.

This guide breaks things down by season, so you can focus on what matters right now and come back to the rest later.

Start with your bills

Before changing anything, pull up your last few utility bills. Most show how much energy or water you used, not just what you paid. Look for:

• Which months cost the most. This tells you which season to focus on first.
• Your usage, not just the price. If usage stayed flat but the bill went up, rates may have changed. If usage jumped, habits or weather may be the cause.
• Any fees or add-ons you don’t recognize. It’s fine to call and ask what they are.

Add your utilities to our bill checklist tool so you can see them alongside your other recurring costs.

Summer: staying cool for less

Cooling can be one of the largest seasonal costs, especially in hot climates. A few habits may help keep both your home and your bill more comfortable.

Use your thermostat wisely

• Set the thermostat a few degrees higher than usual when you’re home, and higher still when you’re away.
• If you have a programmable or smart thermostat, set a schedule so it isn’t cooling an empty house.
• Avoid setting it very low to “cool down faster.” Most systems cool at the same speed regardless, so it mainly just runs longer.

Block the heat before it gets in

• Close blinds and curtains on sunny windows during the hottest part of the day.
• Open windows in the cooler early morning or evening, if it’s safe and comfortable to do so, then close them as it warms up.
• Use fans to help air move. A fan cools people, not rooms, so turn it off when you leave.

Cut indoor heat

• Cook outdoors, use a microwave or slow cooker, or prepare no-cook meals on very hot days.
• Run the dishwasher and dryer in the evening when it’s cooler.
• Switch to LED bulbs, which give off less heat than older incandescent bulbs.

Keep your system running well

Replace or clean your air conditioner’s filter regularly. A clogged filter makes the system work harder. If you have a window unit, make sure it fits snugly and seal any gaps around it.

A quick safety note: in extreme heat, staying safe comes first. If your home becomes dangerously hot, check with your local government or call 211 to ask about cooling centers in your area.

Fall: getting ready for colder months

Fall is a good time for small preparation tasks that pay off all winter:

• Check windows and doors for drafts. Hold your hand near the edges on a windy day, or watch for a candle flame to flicker.
• Use weatherstripping or caulk to seal gaps. Both are usually inexpensive at hardware stores.
• Replace your furnace filter before the heating season starts.
• Reverse ceiling fans to spin clockwise at low speed, which can push warm air down from the ceiling.

Winter: staying warm without overspending

Heat people, not empty rooms

• Lower the thermostat a little and add layers, like a sweater, warm socks, or an extra blanket.
• Lower it further at night and when no one is home.
• Close doors and vents to rooms you rarely use, if your system allows it.

Let the sun help

Open curtains on sunny, south-facing windows during the day to let warmth in, then close them at night to help hold it.

Be careful with space heaters

Space heaters can help warm one room, but they can also use a lot of electricity and carry fire risk. If you use one, follow the safety instructions, keep it away from anything flammable, and never leave it running unattended.

Spring: a good time to reset

Spring often brings milder weather and lower bills, which makes it a smart time to review:

• Clean or replace filters as you switch from heating to cooling.
• Check for leaky faucets and running toilets. Even a small drip adds up over time.
• Wash clothes in cold water when it works for the load.
• Air-dry clothes on a rack or line when the weather allows.

Year-round habits

Some habits help in every season:

• Unplug or switch off devices that draw power when idle, or use a power strip you can turn off at once.
• Run full loads in the dishwasher and washing machine.
• Take shorter showers and consider a low-flow showerhead.
• Lower your water heater temperature to a comfortable, safe setting if it’s set higher than you need. Check your manufacturer’s guidance first.

A worked example

For example, imagine a household whose summer electric bill is around $200 a month. They decide to try three changes: raising the thermostat a couple of degrees, closing curtains on the sunny side of the house, and running the dryer at night.

In this illustration, if those habits trimmed the bill by about $20 a month across three summer months, that would be around $60 for the season. These numbers are made up to show the idea. Actual results depend on your climate, home, equipment, and local rates.

Ask your utility company

Many utility companies offer options that are easy to miss. When you call, you can ask:

• Whether they offer budget billing, which spreads costs more evenly across the year so you don’t get surprised by seasonal spikes.
• Whether they provide free or low-cost home energy checkups.
• Whether there are rebates for things like efficient bulbs, thermostats, or appliances.
• What payment plan options exist if you’re behind.

It’s a good idea to call before a bill becomes overdue. Companies often have more flexibility when you reach out early.

If bills feel out of reach

Sometimes habits alone aren’t enough, especially when income is tight. Programs exist to help with home energy costs and weatherization. Our guide on help with energy bills explains how these programs generally work and where to learn more. You can also call 211 to ask about local resources.

Your next small step

Look at the season you’re in right now. Pick one tip from that section and try it this week. Then make a note to check your next bill and see how it compares.
