ClimateMaster 816 Replacement Omega Condo Heat Pump
The ClimateMaster 816 vertical-stack water-source heat pump was one of the most widely installed models in high-rise condominiums across the Greater Toronto Area. These systems provided dependable heating and cooling for years but are now approaching or beyond their service life.
Because the original 816 models use R-22 refrigerant and are no longer supported by the manufacturer, the best solution today is a direct-fit replacement chassis from modern OEM or aftermarket suppliers.
At 4Most Energy, we specialize in ClimateMaster 816 replacements for condos and commercial units in Downtown Toronto, North York, Mississauga, Vaughan, Markham, Scarborough, and Richmond Hill.
We install drop-in chassis replacements that match your existing cabinet and risers, providing a quick, quiet, and energy-efficient upgrade with no drywall or plumbing modifications.

ClimateMaster 816 FAQs
Most Toronto condos built between the late 1990s and early 2010s were equipped with ClimateMaster 816 vertical stack heat pumps — especially in buildings across Downtown Toronto, North York, Mississauga, Vaughan, and Markham.
You can confirm your model by checking:
- Model label:
- Open the lower front access panel of your unit (usually behind the return air grille).
- Look for a silver or white manufacturer label showing the model number, serial number, and refrigerant type.
- If the model number starts with “816-” (e.g., 816-10, 816-15, 816-20), your unit is a ClimateMaster 816 series.
- Brand marking:
- Many older units show the ClimateMaster logo on the control box or compressor plate.
Some versions were rebranded under Carrier or McQuay, but the model number still starts with 816- if it’s from this series.
Absolutely. We specialize in direct-fit replacements for the 816 series across the GTA. Our licensed TSSA-certified technicians remove the old chassis and install a new high-efficiency R-410A unit — typically within a few hours and without disturbing your suite finishes.
Most 816 models use R-22 refrigerant, which is now phased out in Canada. Once the compressor fails, repair costs can exceed replacement value. A new R-410A system improves efficiency by 30-40 %, operates more quietly, and ensures future serviceability.
- Omega RPC-CM-816 Series (OEM-fit replacement).
- Adirondack-Aire zerOzone 816 Series (Cold Point Corporation)
Both are manufactured to match the form, fit, and function of the original 816 model.
Check the model tag on your existing ClimateMaster unit (e.g., 816-10, 816-15, 816-20).
