The project
This Lower Mainland home required a full mechanical room upgrade — two complete Lennox heat pump systems with matching air handlers, all-new custom sheet metal ductwork, refrigerant line sets, condensate plumbing, and dedicated electrical. The project involved coordinating two separate systems running side-by-side in a tight mechanical space, with custom-fabricated ductwork transitions to match the existing distribution. Both units carry the Grove Mechanical Ltd. service label and were commissioned and tested before handoff. The result is a clean, professional mechanical room built to last.
Installing two full heat pump systems side by side in a residential mechanical room requires careful planning of ductwork routing, refrigerant line paths, electrical runs, and condensate drainage — all without creating access problems for future servicing. Grove Mechanical's sheet metal team pre-fabricated all transitions before installation day to minimize on-site time.
The existing duct distribution required custom-sized plenums and transitions to connect the new air handlers. Grove Mechanical's in-house Red Seal sheet metal workers fabricated all pieces to exact measurements, ensuring proper airflow and a clean finished appearance.
Two heat pump systems require two dedicated electrical circuits, two disconnect boxes, and two sets of low-voltage control wiring. Grove Mechanical coordinated the full scope in-house through Grove Electric Ltd., eliminating the need for a separate electrical contractor and reducing scheduling delays.
Both systems were installed, commissioned, and tested in a single project. The homeowner now has two independent, high-efficiency Lennox heat pump systems providing heating and cooling for different zones of the home — with full Grove Mechanical service labels, warranty registration, and a clean mechanical room built to professional standards.
Yes — many larger homes benefit from two separate heat pump systems serving different zones or floors. This gives you independent temperature control for each zone and redundancy if one system needs servicing. Grove Mechanical has experience designing and installing multi-system homes throughout the Lower Mainland.
Yes. Grove Mechanical has Red Seal-certified sheet metal workers on staff who fabricate custom ductwork, plenums, and transitions in-house. This means faster turnaround, better fit, and no coordination delays with a separate sheet metal subcontractor.
Heat-pump projects can involve current equipment, existing-heating-source, contractor, documentation, and application requirements. Grove can review the home and published terms; the applicable administrator determines eligibility and payment.
