This Central Heat Pump Was Installed on Stilts by the Riverside: Here's How We Did It

A Unique HVAC Installation Tailored to the Challenges of a Flood-Prone Residence

At AirGreen, we regularly handle complex HVAC installation projects, but certain cases stand out due to their uniqueness. This was precisely the case for a recent installation of a central heat pump on stilts, right by the riverside in Laval. This exceptional achievement clearly highlights our technical expertise, adaptability to challenging environments, and our commitment to offering customized solutions to our clients.

An Unusual Installation Project in Laval: Context and Challenges

This project was located in a flood-prone area along the riverside in Laval—a beautiful geographical location, but one that presents significant constraints for any HVAC installation. The owner, determined to maintain comfortable indoor temperatures despite environmental challenges, contacted AirGreen to install a robust central heat pump capable of operating efficiently even during rising water levels.

Our primary challenge was securing the outdoor unit durably and safely on specially designed stilts while ensuring optimal efficiency and consistent thermal comfort throughout the home.

Why Choose a Central Heat Pump Installed on Stilts?

Considering periodic flooding risks, installing the unit on stilts wasn't just recommended—it was a necessary step to ensure the system's durability and safety. This method offers several decisive advantages:

  • Optimal protection against floods: The elevated outdoor unit remains protected during water level rises.

  • Simplified accessibility for HVAC maintenance: Allows rapid interventions without constraints, even after flooding events.

  • Compliance with local regulations specific to flood-prone areas in Laval and surrounding regions.

Equipment Choice: The Trane XV20i Central Heat Pump

To precisely meet the specific needs of this project, we opted for the Trane XV20i central heat pump, renowned for its performance and robustness:

  • Brand: Trane, globally recognized for superior quality and durability.

  • Model: XV20i, specifically suited to challenging climatic conditions.

  • Heating Capacity: 48,000 BTU, ideal for efficiently covering the entire living space.

  • Energy Efficiency: SEER rating up to 22, significantly reducing energy bills.

  • Eligible for Hydro-Québec's LogisVert grant, considerably reducing installation costs for residents of Laval, Montréal, Longueuil, the North Shore, and the South Shore.

Precise and Methodical Stilt Installation Process

The complexity of this project demanded a rigorously structured approach. Our expert team proceeded with the following steps:

  1. In-depth site assessment: Complete evaluation of flooding risks and precise determination of stilt height.

  2. Custom-built stilts: Installation of galvanized steel stilts specially treated against corrosion, designed to durably support weight and climatic conditions.

  3. Secure installation of the outdoor heat pump: Solidly fastening the unit onto the elevated structure, with waterproof electrical connections ensuring safe operation.

  4. Installation of waterproof underground conduits: Ensuring secure connections between the outdoor and indoor units, eliminating any risk of water infiltration.

Challenges Encountered and Solutions Provided by AirGreen

Installing a central heat pump on stilts alongside a river in Laval posed unique technical challenges:

  • Management of extreme humidity risks: The Trane XV20i outdoor unit was chosen for enhanced resistance to humid conditions, ensuring reliability and durability over time.

  • Structural stability of the stilts: Rigorous strength testing and deep anchoring guaranteed installation stability despite variable ground conditions.

  • Strict compliance with municipal regulations: Close coordination with local authorities ensured full compliance with legal requirements applicable to sensitive zones.

Our expertise allowed us to overcome each challenge, ensuring a reliable and safe installation for many years to come.

Achieved Results: Comfort, Safety, and Peace of Mind

Thanks to this innovative installation, the homeowner now enjoys:

  • Optimal thermal comfort year-round, despite geographic constraints.
