About Heat Pump Installation in St. Louis
Heat pump installation covers both heating and cooling using air-source, ground-source (geothermal), or ductless mini-split systems. Heat pumps are highly efficient — modern models work well even in cold climates and can replace both your furnace and air conditioner.
Typical costs: Air-source heat pump systems run $5,000–$12,000 installed. Ductless mini-splits are $3,000–$8,000 for a single or multi-zone setup. Ground-source (geothermal) systems are $15,000–$35,000.
Common projects include:
- Air-source heat pump installation
- Ductless mini-split system
- Heat pump replacement and upgrade
- Geothermal / ground-source system
- Hybrid heating system (heat pump + furnace)
Heat pump installations require mechanical and electrical permits. Ground-source systems may also need well permits for the ground loop.
Frequently Asked Questions
- How much does heat pump installation cost in St. Louis?
- A whole-home air-source heat pump replacing an existing furnace/AC runs $5,000–$12,000. A ductless mini-split for 1–3 zones is $3,000–$8,000. Federal tax credits (up to $2,000) and utility rebates can significantly reduce the net cost. Geothermal is $15,000–$35,000 but offers the highest efficiency.
- How do I find a reliable heat pump installation contractor in St. Louis?
- Choose an installer with specific heat pump experience — heat pumps have different sizing and installation requirements than traditional HVAC. They should perform a Manual J load calculation. Ask about cold-climate performance ratings (HSPF2) if you're in a northern area.
- Do I need a permit for heat pump installation in St. Louis?
- Heat pump installations require mechanical and usually electrical permits. Your contractor should handle the permit process. Federal and local rebate programs often require permitted installation to qualify.
