Pittsburgh natural gas prices fluctuate significantly based on winter demand and pipeline capacity constraints serving Western Pennsylvania. Duquesne Light electricity rates have increased steadily as coal plants retire and infrastructure upgrades continue across the regional grid. Your heating costs from November through March represent your largest utility expense. Older furnaces running at 80 AFUE waste one dollar out of every five you spend on natural gas. Upgrading to a 95 AFUE condensing furnace recovers that wasted fuel, which translates to hundreds of dollars in annual savings. When you finance that upgrade through HVAC payment plans and claim available utility company rebates, your monthly loan payment often equals or falls below your utility bill reduction. The system pays for itself.
