The company holds LSLBC contractor license #23760, Lennox Premier Dealer status (verified on Lennox's residential dealer locator), and EPA and NATE certifications.

Regulatory Context
Geothermal Permitting in Louisiana
Geothermal heat pump installations in Louisiana require specific permits and compliance with state regulations regarding well drilling, loop installation, and refrigerant handling. Contact your local building department for specific requirements in your area.
Geothermal heat pump installation in Norco typically costs between $18,000–$45,000 depending on system size, loop type (vertical vs. horizontal), lot conditions, and home square footage. Available state and utility incentives can reduce net cost (federal §25D credit ended Dec 31, 2025 under OBBBA; §48 commercial ITC may still apply). Request quotes from multiple certified installers in Louisiana to compare pricing.
Most Louisiana municipalities require permits for geothermal well drilling and ground loop installation. Requirements vary by county — some require driller licensing, environmental impact review, or water well permits. Your geothermal installer should handle the permitting process. Contact your local Norco building department for specific requirements.
Geothermal heat pumps typically last 20–25 years for the indoor unit and 50+ years for the ground loop. In Norco's climate, a properly maintained system provides reliable heating and cooling with minimal degradation. Annual professional maintenance and filter changes every 3 months help maximize system lifespan.
Most properties in Norco, Louisiana can support geothermal systems. Vertical loop systems require minimal land area (as little as a standard residential lot), while horizontal loops need more yard space. A qualified installer will conduct a site assessment including soil conductivity testing to determine the best loop configuration for your property.
