Key Cost Factors
- Unit Size and Tonnage: Larger homes require larger HVAC units, measured in tonnage, which directly impacts the cost. For example, a 3,000-square-foot home may require a larger, more expensive system.
- Type of System: Different HVAC systems (e.g., central air, heat pumps, furnaces) have varying costs. Heat pumps and central air conditioning units have different price points.
- Efficiency Rating (SEER/SEER2): Higher efficiency units, while more expensive initially, can lead to long-term energy savings. The average cost for a 14.3 SEER2 AC and gas furnace system for a 3,000-square-foot home is around $16,977.
- Ductwork and Copper Lines: If your existing ductwork or copper lines need replacement, this will add significantly to the overall project cost. A standard system without duct or copper replacement might be around $8,500, while including them could bring the cost to $12,000.
- Brand and Warranty: The brand of the HVAC system and the warranty offered can influence the price. Some systems come with a 10-year part and 10-year labor warranty.
- Installation Complexity: Homes with difficult-to-access areas or complex layouts can increase labor time and, consequently, the overall cost of installation.
