System-Specific Costs
Factors Affecting HVAC Installation Costs
Home Size Impact
The size of your home significantly affects installation costs:
System Configuration Costs
Different HVAC configurations come with varying price points:
| Configuration | Price Range | Best For |
|---|---|---|
| Central AC + Gas Furnace | $7,400-$22,000 | Common, reliable setup |
| Heat Pump + Air Handler | $7,300-$21,700 | Growing popularity |
| Dual Fuel Systems | $9,600-$28,700 | Maximum efficiency |
| Geothermal Systems | $15,000-$35,000 | Premium efficiency |
| Ductless Multi-Zone | $12,000-$25,000 | Retrofit-friendly |
2025 Price Increases
HVAC prices are expected to rise 10-15% in 2025 due to new EPA regulations requiring environmentally friendly refrigerants. This means a system currently costing $10,000 could increase to $11,500-$12,000.
Ductwork Installation Costs
Ductwork installation is a significant component of HVAC costs, ranging from $1,400 to $17,149 with a national average of $9,293. Costs vary by:
Installation Complexity
- Budget-friendly (small homes): $574-$7,146
- Mid-range (average homes): $1,096-$10,009
- High-end (large, multi-story): $13,338-$19,419
Cost Per Linear Foot
- Standard ductwork: $25-$55 per linear foot
- Basic installation: $13.80-$22.90 per linear foot
- Professional labor: $83-$151 per hour
HVAC System Types Comparison
Split Systems
The most common residential HVAC type, featuring separate indoor and outdoor units connected by copper tubing. Components include outdoor condenser/compressor and indoor evaporator coil with air handler.
Heat Pumps
Energy-efficient systems that provide both heating and cooling by transferring heat rather than generating it. They can be up to 50% more efficient than traditional systems.
Furnaces vs. Boilers vs. Heat Pumps
- Furnaces: Heat air using gas, oil, or electricity; distribute through ductwork
- Boilers: Heat water/steam; distribute through radiators or radiant floor systems
- Heat Pumps: Move heat from outside air/ground; most efficient in moderate climates
Maintenance Costs
Annual Maintenance
Regular HVAC maintenance typically costs $75-$200 per visit, with comprehensive annual plans ranging from $175-$300 for residential systems. Commercial systems cost $500-$2,000 annually.
- System inspection and cleaning
- Filter replacement
- Lubrication and tightening
- System testing and calibration
- Minor repairs
Maintenance Benefits
