The furnace will not heat. Open the short answer that matches.
Short answers on frozen pipes, a furnace that blows cold air or will not turn on, repair cost, and 2026 rebates, each linked to its source.
- Cold air Leave first for a gas smell or a CO alarm. If the air is safe, ENERGY STAR says to check the furnace filter once a month and change it if it is dirty.
- Furnace rebates The federal 25C credit does not cover a furnace placed in service after December 31, 2025. Utility rebates still differ by city and by AFUE (annual fuel utilization efficiency).
- Furnace repair cost HomeAdvisor says furnace repair costs average $318, with a normal range of $133 to $505. Those figures are national, not a bid.
- Won't turn on If your furnace won't turn on, a dirty filter can shut the air handler down. During an outage, never run a generator indoors. Leave first for gas or CO.
- Frozen pipes The National Weather Service says drip hot and cold water, open sink cabinets on outer walls, and set heat no lower than 55 degrees if it still runs.
