Should you replace your gas furnace with a heat pump, or upgrade to a higher-efficiency gas system? Here's the honest comparison — including what the California rebates actually do to the math.
The rebate landscape has fundamentally changed the economics. Here's the comparison most HVAC websites won't show you — with real numbers.
| Factor | Heat Pump System | Gas Furnace + AC |
|---|---|---|
| Typical installed cost | $11,000–$15,000 | $8,000–$13,000 (furnace + AC combined) |
| LADWP rebate | Up to $2,500/ton | $0 (AC only: standard rate) |
| Federal IRA 25C credit | Up to $2,000 | $600 (furnace or AC, not both) |
| Effective cost (3-ton, after rebates) | ~$2,500–$5,500 | ~$7,000–$12,000 |
| Systems replaced | Furnace + AC (both) | Furnace and/or AC (one or both) |
| Heating efficiency | 200–400% (COP 2–4) | 80–98% AFUE |
| Annual operating cost (approx.) | Lower (typically $400–$800 less/yr) | Higher (gas prices, separate AC costs) |
| Works at LA temperatures | ✓ Excellent (40–105°F range) | ✓ Yes |
| Environmental impact | No combustion, grid-powered | Gas combustion, some CO2 emissions |
| CA policy direction | Aligned (incentivized) | Being phased out in new construction |
The rebate math in 2026 changes everything. Before LADWP's enhanced rebate program, gas furnaces were often the cheaper upfront choice. At $2,500/ton, a 3-ton heat pump system's rebates ($7,500 + $2,000 IRA = $9,500) can make a heat pump cost significantly less than a gas system — while providing better efficiency and replacing both appliances. This is a historically unusual situation and won't last forever.
