The Omega VF Series is a drop-in replacement for discontinued McQuay VF, heat pumps.
It’s designed for buildings where the existing McQuay cabinet, risers, and electrical layout are still in good condition, allowing the new chassis to slide in for an instant upgrade.

✅ Equipment only →Just add to cart.
The Omega VF Replacement Chassis is a direct, OEM-fit replacement for older McQuay VF water-source heat pumps commonly found in high-rise condominiums and commercial buildings across the Greater Toronto Area.
Each unit comes factory-charged with R-410A refrigerant and equipped with advanced microprocessor controls, offering quiet operation, higher efficiency, and long-term reliability — making it the perfect solution for aging McQuay systems in Downtown Toronto, North York, Mississauga, Vaughan, Markham, Scarborough, and Richmond Hill.

Yes, 4Most Energy specializes in replacing McQuay VF and VP/VG series heat pumps across the Greater Toronto Area, including Downtown Toronto, North York, Mississauga, Vaughan, Markham, Scarborough, and Richmond Hill.
We install Omega and Adirondack-Aire drop-in replacements that match your existing cabinet and risers exactly, with no renovations needed.
After Daikin acquired McQuay International in 2006, the VF series and other legacy models were discontinued. OEM parts are no longer supported, and sourcing components like compressors or coils has become difficult.
Replacing the entire chassis with a modern R-410A system is the most reliable and cost-effective long-term solution.
Yes. Both Omega VF and Adirondack-Aire VF chassis are dimensionally identical to the original McQuay VF design.
They connect directly to existing risers, drains, and electrical harnesses — allowing for a plug-and-play replacement with no drywall or plumbing changes.
Installation typically takes only a few hours per suite.
The VF and HCA series are visually similar but use different internal configurations and electrical connections.
If your unit label starts with “VF”, you’ll need an Omega VF or Adirondack-Aire VF replacement.
If it’s labeled “HCA”, a different Omega HCA chassis is required.
Our technicians can confirm your model by reviewing a photo of your unit’s nameplate.
R-22 refrigerant used in old McQuay VF units is phased out and no longer available.
R-410A replacements are more energy-efficient and environmentally friendly.
New systems operate quieter, cool faster, and reduce utility costs.
4Most Energy provides a 1-year labour warranty and 5-year compressor coverage for all new installations.
Call or WhatsApp 4Most Energy to speak directly with a Condo Heat Pump Expert, or upload a photo of your existing McQuay unit through our online form.
We’ll identify your model (VF, VP, or VG), confirm the correct replacement chassis, and provide a same-day quote with professional installation and warranty coverage.
