Quick Answer
In Brilliant, a sudden rise in your gas bill usually means the furnace or water heater is staying on longer than necessary. Clogged filters, short cycling, leaking ducts, and water-heater sediment are the most common causes. Each one adds runtime, and longer runtime directly raises fuel use even when the thermostat doesn’t change.
Homes in Brilliant—whether near North Third Street, Clearview Avenue, or along the Ohio River flats—often have older ducts, river-valley drafts, and mineral-heavy water. These conditions make small mechanical issues show up quickly on the monthly bill.
Furnace & Duct Issues in Brilliant
Clogged filters reduce airflow, forcing the furnace to run longer. Some older homes also experience short cycling from oversized units, wasting gas during repeated startups.
Basement duct leakage is common in original sheet-metal systems, sending warm air into unheated areas and making the furnace replace lost heat.
Water Heater Sediment
Hard water in Brilliant speeds sediment buildup inside gas water heaters. This layer slows heating, causing long burner cycles.
Rumbling sounds or slow hot-water recovery often indicate wasted fuel.
FAQs
Why did my bill increase in normal weather?
Because airflow loss, duct leakage, or sediment increases runtime regardless of outdoor temperature.
Is sediment buildup common in Brilliant?
Yes. Mineral-rich water creates fast accumulation in older tanks.
