Heating & Cooling Costs
Cost guidance for furnaces, central air, heat pumps, and common repairs -- including repair-versus-replace decision points.
Heating and cooling costs swing with system age, refrigerant type, duct condition, and whether you are fixing one failure or replacing the whole plant. This hub connects HVAC planning ranges, calculators, and repair-versus-replace guides so you can compare options without mixing scopes.
Start with the symptom or equipment type you have today, then open the matching cost guide or calculator. Pair comfort goals with electrical and duct realities—especially when adding heat pumps or high-efficiency furnaces that change venting and panel load.
Use this hub to jump into national planning ranges, calculators, and repair-versus-replace guides for heating & cooling. Ranges are budgeting tools—compare written local bids for the same scope before you hire. Start with a cost guide for the direct answer, open a calculator when you know size and options, and use problem or comparison pages when you are still diagnosing the right project path.
Planning ranges at a glance
Popular projects
- HVAC ReplacementTypical planning estimate: $12,000Matched furnace and central air (or heat pump) replacement with new refrigerant lines and basic commissioning. Modeled national ranges for a typical 3-4 ton system.
- AC RepairTypical planning estimate: $475Diagnostic and repair work for central air failures -- capacitors, contactors, refrigerant leaks, and airflow issues. High-end ranges often include refrigerant recovery and major component swaps.
- Furnace ReplacementTypical planning estimate: $7,900Gas or electric furnace swap with venting checks and thermostat integration. Planning ranges exclude full duct redesign.
- Furnace RepairTypical planning estimate: $350Igniters, flame sensors, blower motors, and control-board repairs for forced-air heating. Safety shutoffs and carbon monoxide concerns warrant prompt service.
- Heat Pump InstallationTypical planning estimate: $12,500Air-source heat pump install as a primary heating and cooling system. Modeled ranges cover equipment and standard install labor for a typical capacity match.
- Mini-Split InstallationTypical planning estimate: $4,500Ductless mini-split heads for room additions, garages, or homes without ductwork. Per-zone pricing scales with outdoor unit capacity and line-set length.
- Duct CleaningTypical planning estimate: $550Whole-home duct vacuuming and register cleaning. Best treated as optional maintenance after renovations or confirmed contamination -- not an annual must for every home.
- Duct Repair & SealingTypical planning estimate: $1,200Sealing leaks, replacing crushed runs, and balancing airflow. Improves comfort and can reduce runtime after HVAC replacement.
- Thermostat InstallationTypical planning estimate: $300Installing a programmable or smart thermostat, including wiring checks for common and power-extender kits when needed.
- Boiler ReplacementTypical planning estimate: $8,500Hydronic boiler swap for homes with radiators or radiant floors. Modeled ranges cover equipment and standard changeout, not full piping redesign.

Common homeowner problems
- AC Not CoolingWhen a central air system runs without cooling the home, the issue may be airflow, refrigerant, electrical components, or a failing compressor.
- Furnace Not HeatingNo-heat calls are common in cold weather and range from simple filter problems to failed igniters, flame sensors, or blower motors.
Repair-versus-replace & comparisons
- AC Repair vs ReplacementComponent repairs can restore cooling affordably on younger systems; major failures on older, inefficient units often tip toward full replacement.
- Furnace Repair vs ReplacementIgniters and sensors are common affordable repairs; cracked heat exchangers, repeated lockouts, or very old furnaces usually justify replacement planning.
- Heat Pump vs FurnaceFurnaces deliver strong fossil-fuel heat; heat pumps provide heating and cooling in one system and often win on efficiency in milder climates or with dual-fuel setups.

Methodology & estimate disclaimer
Heating & Cooling hub pages summarize national planning ranges and internal links across related cost guides, calculators, and decision pages. They are not contractor quotes.
Actual costs vary by location, home condition, material availability, permits, and project complexity. Read our methodology, the national cost bands table, editorial policy, and disclaimer. Planning provenance uses internal model notes (not invented third-party citations)—see the bands page for published low/typical/high frames.
