Direct answer
When a laundromat gas bill doubles, compare therms usage to the same month last year, check read type and billing days, review rate and rider changes, and inspect whether space heating shares the meter with dryers. Gas-fired dryers dominate therms at many stores—CLA due diligence materials note utilities are a major cost line, so confirm the spike is real usage before assuming equipment failure.
Compare therms, not just dollars, to isolate rate versus usage effects.
Check billing period length and estimated versus actual reads.
Review winter space heating on shared meters with laundry load.
Confirm supplier contract status if gas is competitively supplied.
Inspect dryers, pilots, and water heaters for faults increasing run time.
File dispute paperwork if meter test or read error is suspected.
Step one: decompose the bill
Separate commodity therms from customer charges, taxes, and riders. Note whether the unit rate or total usage moved.
Scale partial months to comparable day counts before panicking.
Usage drivers unique to laundromats
Dryer run hours, water heater setpoints, and makeup air heating can spike therms together.
A broken vent or short-cycling heater may burn gas without proportional coin revenue.
Tariff and supplier effects
Regulated delivery rate cases and supply contract expirations can double dollars with flat therms.
Holdover gas supplier pricing after contract lapse mimics usage spikes on the supply portion only.
When to call the utility versus a technician
Utility for read tests, meter swaps, and rate schedule verification.
HVAC and laundry technicians for burner efficiency, venting, and control faults. Document both tracks for insurance or lease disputes.
Q & A
FAQ
Can a gas leak cause a doubled bill without obvious odor?
Large leaks usually smell or trigger equipment faults, but small pilot or valve issues can waste gas. If usage jumps with no operational explanation, request a utility leak survey and equipment inspection promptly.
Should I compare gas dollars to revenue when a bill doubles?
Utilities often run roughly 20–25% of laundromat revenue nationally per CLA references—a doubled bill may be tolerable short term if revenue also jumped, but sustained therms growth without coins warrants investigation.
Does switching gas suppliers fix a doubled bill?
Only if the spike is on the supply portion in a choice market. Delivery charges and increased therms from equipment or weather remain after switching.
