Natural Gas Bills Explained: What You’re Paying, Why It Changes & How to Lower It

Average gas bills run $30–$60 in summer and $150–$300 in winter — here’s whether yours is normal, why it changes, and the fastest ways to bring it down.

Last updated: March 19, 2026

Natural gas bills are one of the most volatile household expenses, and most utility statements do a poor job of explaining why. In this guide, we cover what you’re actually paying for, whether your bill is normal, and the fastest ways to bring it down.

If you just moved in and are setting up gas for the first time, or you’re weighing gas vs. electric appliances — we cover those too. Jump to the section you need.

Is My Gas Bill Normal? Average Bills by Season

The most common reason people search for natural gas information is a bill that looks wrong. Here’s what normal actually looks like in 2026, based on EIA data:

Summer

$30–$60

Water heating + cooking only

Fall / Spring

$60–$120

Shoulder season, light heating

Winter

$150–$300+

Full heating load, cold climates

These are national averages. Your bill depends on four things: where you live (Idaho averages $7.24/MCF; Hawaii averages $57.88/MCF — source: EIA November 2025), your home’s size and insulation, your heating system’s efficiency, and how cold your winter was.

A $180–$220 winter bill for a 1,500–2,000 sq ft Midwest home heating primarily with gas is normal. That same bill in Florida, where winters are mild, would be worth investigating. If your bill is significantly above these ranges, the next section covers the most common causes.

2025–2026 season note: The EIA’s Winter Fuels Outlook (October 2025) projected the current heating season to be approximately 2% colder than the 10-year average, meaning bills are running slightly higher than the prior winter baseline for most households. Winter Storm Fern in late January 2026 drove record residential demand spikes in affected regions — if you’re in the Northeast or Midwest, a January bill 20–30% above December is consistent with that event, not a billing error.

Why Is My Gas Bill So High?

If your bill is outside the normal range for your area, one of these is almost always the cause. Work through them in order — the most common are listed first.

1. It’s a cold month and that’s just what heating costs. Heating accounts for 50–60% of a home’s total winter gas use. A week of unusually cold weather can add $30–$80 to a monthly bill compared to a mild month. Before investigating further, check whether the billing period covered any significant cold snaps.

2. Your furnace filter is dirty. A clogged filter forces your furnace to run longer to move the same amount of air. Replacing a $10 filter is the highest ROI action most homeowners can take. Check it monthly during heating season — if it’s grey, replace it.

3. Your furnace is old and inefficient. Furnaces built before 2000 typically operate at 60–70% AFUE (annual fuel utilization efficiency) — meaning 30–40¢ of every dollar you spend on gas escapes as waste heat. A 95% AFUE condensing furnace would cut that waste by two-thirds. Upgrading isn’t a quick fix, but it’s why two identical houses can have drastically different bills.

4. Air is escaping. Gaps around window frames, door thresholds, electrical outlets on exterior walls, and attic hatches let heated air out and cold air in. The DOE estimates sealing air leaks and adding insulation reduces heating and cooling costs by 10–20%. Walk the perimeter of your home on a cold day — if you can feel a draft, you’re losing money through that gap.

5. Your water heater is working harder than necessary. Most water heaters ship set to 140°F. Dropping to 120°F saves 3–5% on water heating costs and eliminates scalding risk. If your water heater is more than 10 years old, standby heat loss increases as insulation degrades — this adds to your bill even when no one is using hot water.

6. You received an estimated meter read. If your statement shows an “E” next to usage instead of “A” (actual), the utility estimated your consumption. Sometimes estimates run high. Request an actual meter read and check if the next bill has a significant credit — that’s a sign the estimate was off.

7. A rate adjustment hit your bill. Gas bills contain a Purchased Gas Adjustment (PGA) — a monthly pass-through that reflects what your utility actually paid for gas on the wholesale market. When wholesale prices spike, a PGA surcharge is added to all customer bills. Check your bill for line items labeled “PGA,” “gas cost adjustment,” or “commodity adjustment” — these can add $10–$40 in months following market price spikes.

📄 What Every Line on Your Gas Bill Actually Means

Based on standard residential billing — March 2026

Line ItemWhat It MeansStability

Gas Supply / Commodity Charge

Cost of the gas itself — priced per therm or MCF. This is the part you can shop in deregulated states (OH, IL, PA, NY, NJ).

Example: 42 therms × $0.49/therm = $20.58
National avg: ~$1.49/therm (EIA, Nov 2025)

Changes monthly

Distribution / Delivery Charge

Moving gas through your utility’s pipelines to your meter. Regulated by your state PUC. Doesn’t move with the wholesale market.

Example: Fixed $9.50/month + $0.18/therm variable delivery component

Stable

Customer Charge

Flat monthly fee for maintaining your account and meter connection. Charged every month — even if you use zero gas.

Typical range: $8–$20/month flat, regardless of usage. Non-negotiable.

Fixed

Purchased Gas Adjustment (PGA)

Pass-through of actual vs. projected wholesale costs. Can be a surcharge or credit. Explains why two identical-usage months have different bills.

Range: −$40 to +$40/month. Spikes sharply during extreme cold events or supply disruptions.

Watch this

Usage: “A” vs. “E” Next to Therms

“A” = actual meter read. “E” = estimated. If your bill is high and shows “E”, request an actual read — you may be owed a credit.

Call your utility to request an actual read anytime. Utilities are required to read your meter at least once every few months.

Check this

Taxes & Regulatory Fees

State and local taxes, pipeline tariff fees, utility commission assessments. Varies by state and municipality.

Typical range: 8–15% added to pre-tax bill. Non-negotiable.

Fixed
The number to watch: Your supply charge (per therm) and the PGA together explain most month-to-month bill variation. If your usage stayed the same but your bill is higher, check both of those lines before calling your utility.

How Can You realistically Lower Your Gas Bill?

Ranked by impact, not effort. The first three on this list are responsible for a good portion of residential gas savings.

Lower your thermostat setback (saves ~3% per degree, free). Every degree you reduce the thermostat saves approximately 3% on heating costs. Dropping from 72°F to 68°F while sleeping or away from home saves around 10–12% annually on the heating portion of your bill. A programmable thermostat ($20–$50) automates this without any comfort sacrifice.

Air seal before you insulate ($100–$500, highest ROI per dollar spent). Plugging air leaks — around outlet plates, pipe penetrations through exterior walls, the sill plate where your house sits on the foundation, and the attic hatch — prevents heated air from escaping. This is more effective than adding insulation on top of a leaky envelope. Hardware stores sell foam gaskets for outlets and caulk for window frames. For a thorough job, a home energy auditor ($200–$600) identifies the highest-priority leaks with a blower door test. The federal Energy Efficient Home Improvement Credit (25C) covers 30% of the cost of insulation and air sealing up to $1,200/year.

Drop your water heater to 120°F (free, immediate). The factory setting of 140°F is higher than most households need. Reducing to 120°F saves 3–5% on water heating costs with no perceptible impact on daily use. Find the dial on the water heater tank — it’s usually on the front near the bottom.

Replace the furnace filter monthly during heating season ($10–$15/month). A clogged filter reduces airflow and forces longer run times. Check it monthly from October through March. If it looks grey and dense, replace it immediately.

Service your furnace annually ($80–$150). A dirty burner and heat exchanger reduce efficiency and increase carbon monoxide risk. Annual tune-ups maintain the furnace’s rated efficiency and catch problems before they become expensive failures or safety issues.

In deregulated states: shop your gas supplier before winter. If you’re in Ohio, Illinois, Pennsylvania, New York, New Jersey, or another state with retail gas choice, you can choose a supplier separate from your delivery utility. The supply charge is typically 40–60% of your total bill — locking in a competitive fixed rate before the heating season can save $10–$25/month compared to the utility’s variable default rate.

Apply for LIHEAP if income-eligible. The Low Income Home Energy Assistance Program provides federally funded heating bill assistance for qualifying households. Benefits vary by state but can be significant. Apply through your state’s LIHEAP office — applications typically open in fall before the heating season. Eligibility is income-based; apply early, as funding is limited and allocated on a first-come basis.

How to Read Your Gas Bill

Gas bills are intentionally confusing — they combine a commodity cost, a delivery cost, multiple fixed charges, and regulatory adjustments into one statement. Here’s what each line actually means:

Gas supply / commodity charge — the cost of the gas itself, priced per therm or MCF. This is the line that changes month to month. One therm = 100,000 BTUs of energy. One MCF (thousand cubic feet) ≈ 10.2 therms for most residential gas. The national average residential gas rate was $14.87/MCF as of November 2025 (EIA). Your state may be significantly above or below that.

Distribution / delivery charge — what the utility charges to move gas through its pipelines to your meter. Regulated and relatively stable. Often includes a fixed customer charge ($8–$20/month) regardless of how much gas you use, plus a variable per-therm delivery fee.

Customer charge — a flat monthly fee for maintaining your account and meter. This is why you receive a bill even in months where you use zero gas. It’s non-negotiable and shows up every month.

Purchased Gas Adjustment (PGA) — a monthly pass-through that reflects the difference between what your utility projected it would pay for gas and what it actually paid. Positive PGA = surcharge (wholesale prices were higher than expected). Negative PGA = credit. This is one of the main reasons two consecutive months of identical usage can produce different bills.

Usage: “A” vs. “E” — look for this designation next to your usage figure. “A” = actual meter read. “E” = estimated. If you see “E” and your bill seems high, request an actual read. Your utility is required to do one at least once every few months, but you can request one anytime.

Taxes and regulatory fees — state and local taxes, pipeline tariff fees, and utility commission assessments. These vary significantly by state and municipality and can add 8–15% to the pre-tax bill.

Gas vs. Electric: Which Costs Less in Your Home?

This is one of the most searched home energy questions — and the honest answer is: it depends on your local rates. Here’s what the data actually shows at the national level in 2026.

Heating: Homes using natural gas for heating, cooking, and clothes drying save an average of $1,030 per year compared to all-electric equivalents, according to the American Gas Association’s 2026 Playbook. In most U.S. markets, gas heating costs less per BTU than electric resistance heating. The exception is modern air-source heat pumps — they move heat rather than generate it, operating at 200–400% efficiency, which closes or eliminates the cost advantage of gas in mild climates. In very cold climates (Minnesota, Michigan, Maine), gas furnaces typically maintain the cost edge over heat pumps during the coldest weeks.

Water heating: Gas water heaters cost less to operate than electric resistance heaters in most markets. Heat pump water heaters (electric) are competitive — they operate at 3–4× the efficiency of resistance heaters and can match or beat gas operating costs. The upside-down economics: heat pump water heaters cost $1,000–$1,400 upfront versus $400–$700 for a gas unit.

Cooking: Negligible cost difference — cooking represents a tiny fraction of total home energy use. This choice is almost entirely about cooking preference, not economics.

Clothes drying: Gas dryers have lower per-load operating costs in most markets. Heat pump dryers (electric) narrow the gap but cost significantly more upfront.

How to run your own numbers: Take your electricity rate in ¢/kWh and your gas rate in $/therm. Multiply the electricity rate by 29.3 to get the cost per million BTU (MMBtu). Divide your gas rate by 10 to get the cost per MMBtu. Compare the two directly. If electricity per MMBtu is lower — often true in states with cheap electricity and expensive gas — electric appliances may cost less to run.

Can You Choose Your Gas Supplier?

In most states, no — your local utility is your only option and your rates are set by your state’s public utility commission. But in a growing number of states, you can shop your gas supply the same way you’d shop electricity in deregulated markets.

States with residential natural gas choice: Ohio, Illinois, Pennsylvania, New York, New Jersey, Georgia, Maryland, Michigan, Indiana, and several others. In these states, your local utility (Nicor, Columbia Gas, National Grid, etc.) still owns the pipes and responds to emergencies — you can’t change that. What you can shop is the commodity supply charge, which represents roughly 40–60% of your total bill.

What to compare when shopping suppliers:

  • Fixed vs. variable rate: Fixed locks your supply price for a contract term (typically 6–24 months). Variable floats monthly with the market — can be cheaper in mild years, significantly more expensive during cold snaps or supply disruptions. For most households, a fixed rate through winter provides the most predictability.
  • Contract term and early termination fee: If you might move within a year, check whether the contract has a $50–$200 ETF for breaking it early.
  • Total cost per therm, not just the supply rate: Some suppliers advertise a low supply rate but add service fees that offset the savings. Ask for the all-in cost per therm before signing.
  • Budget billing option: Many utilities and suppliers offer budget billing that averages your annual cost into equal monthly payments — eliminates winter bill shock. Especially useful for households on fixed monthly budgets.

Setting Up Gas at a New Address

Moving is one of the most common reasons people search for gas information. Here’s the short version — follow the link below for the full guide with checklist.

Gas activation requires a technician visit if service has been off at the property. You must be home. Plan for a 2-week lead time — longer during May–August peak moving season when technician scheduling fills up. Don’t wait until move-in week.

What you’ll need: your new address and move-in date, government-issued ID, Social Security Number for the credit check (utilities can ask but not require it), and payment for the deposit if one is required. Deposits are typically 1–2 months of estimated usage, refunded after 12 consecutive months of on-time payments. A letter of credit from your previous utility showing 12 months of on-time payments can often waive the deposit.

On activation day: the technician turns on the gas, checks for leaks, and lights pilot lights on applicable appliances. Do not attempt to light any gas appliance before the technician has confirmed the system is active and safe.

A gas fireplace can add 50–200 therms/year. A pool heater can double a summer bill. If you have these and don’t account for them, they will look like a billing error.
Key takeaway: Space heating dominates your winter bill — everything else is noise by comparison. Furnace efficiency, insulation, and thermostat setback will reduce your bill far more than any other single action.
Residential natural gas usage by appliance. Annual therm estimates for a typical U.S. home in a cold climate. Based on EIA Residential Energy Consumption Survey data. Actual usage varies by home size, efficiency, and climate. March 2026.

About 46% of U.S. homes use natural gas as their primary heating fuel — making it the most common residential heating source, ahead of electric heating (42%), per EIA’s 2025 Winter Fuels Outlook. Around 60% of U.S. households use gas for at least one purpose.

The four main residential uses, ranked by how much gas they consume:

Space heating (largest use by far). Your furnace or boiler accounts for the majority of winter gas consumption. A typical gas furnace runs 1,500–2,500 therms per year in a cold climate. Heating accounts for 50–60% of total winter gas use in homes that heat with gas.

Water heating (second largest). A gas water heater runs year-round and typically uses 200–300 therms per year for a family of four. If your summer gas bill is $40–$60, this is almost entirely your water heater. Tankless (on-demand) water heaters reduce standby heat loss and can cut water heating costs by 20–30% for moderate-use households.

Cooking. A gas range uses roughly 40–60 therms per year — a small fraction of total consumption. If your household cooks frequently, you’ll notice a slight seasonal variation, but cooking is not a meaningful driver of high bills.

Clothes drying. A gas dryer uses approximately 20–30 therms per year. Like cooking, it’s a minor contributor to total usage. Gas dryers are faster and typically cheaper to operate than electric resistance dryers.

Other gas uses that can add meaningfully to bills: gas fireplaces (can use 50–200 therms per year depending on usage), pool or spa heaters (can double a summer gas bill), standby generators, and outdoor grills with dedicated gas lines.

Natural Gas Safety: What Every Household Needs to Know

Natural gas is safe when properly maintained. These are the basics that every adult in a gas-using household should know — not just the primary bill-payer.

What a gas leak smells like: Natural gas is colorless and odorless in its natural state. Gas utilities add mercaptan — a sulfur compound — that produces a distinctive rotten egg smell as a warning signal. If you smell it, treat it as a leak immediately.

If you smell gas — do this in order:

  1. Do not touch any electrical switches, outlets, or lights
  2. Do not use your phone inside the building
  3. Leave the building immediately — leave doors open as you go
  4. Once outside and away from the building, call your gas utility’s 24/7 emergency line or 911
  5. Do not re-enter until the utility has inspected and cleared the building

Carbon monoxide (CO) — separate from a gas leak, equally serious. CO is produced by incomplete combustion in gas appliances — furnaces, water heaters, stoves, and generators. It is colorless and odorless. Install CO detectors on every level of your home and within 15 feet of each bedroom. CO detectors have a lifespan of 5–7 years — check the manufacture date on the back of yours. If it’s expired, replace it.

Know where your gas shutoff is. The main shutoff valve is at the meter, typically outside your home. Turning it 90 degrees with a wrench closes it. After shutting off gas, do not turn it back on yourself — call your utility. Relighting appliances after a shutoff requires following each appliance manufacturer’s specific procedure.

Annual appliance inspection. Gas furnaces and water heaters should be inspected by a licensed technician annually. A cracked heat exchanger on a furnace is a CO risk and will not present obvious symptoms until it’s a serious problem. Don’t defer annual service on gas heating equipment.

Pilot lights. A pilot light that goes out repeatedly is not automatically a gas leak, but it should be investigated. If there’s no gas smell: turn off the gas valve, wait 5 minutes, then follow the appliance’s relight instructions. Persistent pilot problems indicate a faulty thermocouple or dirty orifice — a licensed gas technician should diagnose it.

Frequently Asked Questions

Does natural gas go up in price every winter?

Retail rates don’t necessarily increase each winter, but your bill does — because you’re using more gas to heat your home. The bill increase is almost always from higher consumption, not higher rates. That said, wholesale natural gas prices did spike significantly during Winter Storm Fern in January 2026 (briefly hitting $30+/MMBtu before retreating). Retail rates lag wholesale by weeks to months due to regulatory approval processes, so some utilities may pass through modest rate adjustments later in 2026. The EIA’s March 2026 forecast projects the Henry Hub spot price to average approximately $3.80/MMBtu for 2026 — lower than earlier projections due to milder February weather.

What’s a therm and how many does a home use per year?

One therm = 100,000 BTUs of energy. A typical U.S. home using gas for heating, water heating, and cooking uses approximately 500–1,200 therms per year, depending on climate, home size, and efficiency. Cold-climate homes can exceed 1,500 therms in harsh winters. Your annual therm usage is listed on your December or year-end statement — divide by 12 for your average monthly use, though actual monthly consumption varies significantly with weather.

Can my landlord make me pay for gas that was included in my lease?

No. If your lease states that gas is included in rent, your landlord cannot legally bill you separately for it. If there is any ambiguity in the lease about who is responsible for gas, clarify in writing before moving in. Utility billing disputes between landlords and tenants are among the most common complaints filed with state housing authorities. If you believe you’ve been improperly charged for gas your lease says is included, contact your state’s tenant rights office or public utility commission.

Is propane the same as natural gas?

No. Natural gas is delivered through underground utility pipelines at low pressure. Propane is compressed into liquid form, stored in tanks on your property, and delivered by truck — more common in rural areas without pipeline access. The two fuels are not interchangeable; appliances designed for one require conversion to use the other. Propane contains roughly 2.5× more energy per cubic foot than natural gas, but typically costs more per BTU in most markets.

My gas bill shows $0 usage but I still have a charge. Is that right?

Yes, and it’s legal. The fixed customer charge ($8–$20/month at most utilities) covers the cost of maintaining your meter and account, and it appears every month regardless of usage. If you use zero gas in a summer month, you’ll still receive a bill for this charge. It’s non-negotiable and applies to all residential customers on the rate schedule.

What is a budget billing plan and should I sign up?

Budget billing — sometimes called “level pay” or “equal payment plan” — averages your estimated annual gas cost into equal monthly payments. Instead of a $30 June bill and a $280 January bill, you pay roughly the same amount every month. It doesn’t save you money, but it eliminates seasonal bill shock and makes monthly budgeting easier. At the end of the 12-month period, the utility reconciles actual vs. estimated usage and either credits or bills the difference. Most utilities offer this at no charge — contact your utility to enroll.
