When does a heat pump pay for itself in St. Louis?
Payback depends on what you're replacing. Replacing a gas furnace + AC system, a heat pump typically breaks even in 5–10 years through energy savings. The $2,000 IRA federal tax credit (available through 2032) plus any state or utility rebates can cut the payback period by 2–4 years. A properly sized system from an HVAC professional is essential — oversized heat pumps short-cycle and fail to dehumidify properly.

Missouri does not require a statewide general contractor or roofing license. Confirm active general liability insurance (minimum $1M) and workers' compensation coverage. Get written proof of both before work starts.
