Central Split = separate AC + furnace. Heat Pump handles both heating & cooling.
The single biggest misconception homeowners have about HVAC is assuming the unit price equals the project price. In reality, equipment typically accounts for 40–55% of total cost. Labor, refrigerant, electrical work, permits, and disposal of the old system make up the rest.
For a typical 3-ton central split system in the Midwest, equipment might cost $2,500–$4,000, while total installed cost lands at $5,500–$8,500. The gap widens even more in high-cost metros like New York or San Francisco, where labor alone can reach $3,000–$5,000.
Since 2023, new HVAC equipment must meet the updated SEER2 (Seasonal Energy Efficiency Ratio 2) standards, which replaced the old SEER metric. Minimum efficiency varies by region: 13.4 SEER2 in the North, 14.3 SEER2 in the South and Southwest.
High-efficiency systems (20+ SEER2) cost significantly more upfront — typically $2,000–$5,000 more than baseline models — but can reduce cooling energy use by 30–45% compared to older systems. Break-even on the efficiency premium typically runs 5–9 years depending on climate and utility rates.
Heat pumps have surged in popularity for good reason: a single system handles both heating and cooling, and modern cold-climate models operate efficiently down to 0°F or below. They eliminate the need for a separate furnace in most climates.
The trade-off is higher upfront cost — typically $1,500–$3,000 more than a comparable central split system. However, Federal Tax Credits under the Inflation Reduction Act cover 30% of heat pump installation costs up to $2,000 per year, making heat pumps increasingly cost-competitive.
// 2026 Cost Note: Material costs have risen 3–6% year-over-year due to equipment demand, labor shortages, and ongoing tariffs on imported HVAC components. Ask your contractor specifically whether tariffs affect your quoted equipment before signing.
The rule of thumb used by most HVAC contractors is the "$5,000 rule": multiply the system age by the repair cost. If the result exceeds $5,000, replacement is the better investment. A 15-year-old system needing a $400 repair gets a score of $6,000 — a signal to replace.
Other replacement signals include refrigerant leaks in R-22 systems (R-22 is no longer manufactured and costs $100–$175/lb to recharge), frequent breakdowns, rising energy bills despite no usage changes, or uneven comfort throughout the home.
