Mitsubishi Zuba Central Built for Canadian winters.
Premium whole-home heating and cooling for centrally ducted homes. The latest Zuba Central lineup combines Mitsubishi Electric Hyper-Heat technology with lower-GWP R-454B refrigerant.
A complete central heat pump system
Zuba Central connects to new or existing ductwork to heat and cool the entire home. Its inverter compressor continually adjusts output instead of repeatedly switching fully on and off, helping maintain steadier temperatures and quieter operation.
- Multi-position SVZ or PVA central air handler configurations
- Primary whole-home heating and air conditioning
- Hot Start technology helps reduce cold drafts
- Optional electric resistance backup heat
- Professional sizing, duct review and commissioning
Choose all-electric or hybrid comfort
Both use your home's central duct system. The right design depends on your current equipment, electrical capacity, comfort goals and energy source.
Zuba Central + air handler
Replace the furnace and air conditioner with a purpose-built Mitsubishi Electric air handler and Hyper-Heat outdoor unit.
Zuba + furnace coil
Pair a compatible furnace with a Mitsubishi Electric PAA central coil. The heat pump handles efficient heating and cooling, while the furnace provides automatic backup when selected.
Built around your home
City Home Comfort checks heat loss, electrical service, duct capacity, equipment location and controls before recommending a configuration.
Flexible installation without ductless wall heads
The multi-position air handler can support upflow, downflow and horizontal layouts, making Zuba Central suitable for many furnace rooms, basements, attics and tight mechanical spaces.
What changes with R-454B?
R-454B is the refrigerant used in Mitsubishi Electric's newest Zuba systems. It has substantially lower global warming potential than R-410A while supporting the high-performance cold-climate technology Zuba is known for.
Because R-454B is classified A2L, the equipment, controls and installation practices are designed around its mildly flammable classification. City Home Comfort uses trained technicians and the proper tools required for A2L commissioning and service.
A premium system deserves a careful installation
Equipment selection is only one part of performance. We design the complete system around the home's actual heating load and airflow requirements.
Accurate system sizing
We evaluate the home, ductwork and existing utilities before final equipment selection.
In-house technicians
Our own trained team completes the installation, startup testing and homeowner orientation.
Local GTA service
Family-owned since 1981, with ongoing maintenance and 24/7 emergency support.
Zuba Central answers
Is Zuba Central a ductless heat pump?
No. This page is for centrally ducted Zuba systems. Zuba Central uses an air handler or hybrid furnace coil connected to ductwork to condition the whole home.
Can Zuba Central heat a Toronto home without a furnace?
Yes, an all-electric Zuba Central system can be designed as the primary heating and cooling system. Proper heat-loss sizing, duct airflow and backup-heat planning are essential.
Can I keep a gas furnace?
Often, yes. A Zuba Hybrid configuration can pair a Mitsubishi Electric PAA coil with a compatible furnace, allowing the system to switch heat sources according to the selected controls and balance point.
How cold will the new R-454B system operate?
The current central brochure lists 100% heating power at −15°C and exceptional heating performance at −30°C, depending on the matched model and operating conditions. City Home Comfort will confirm the exact performance of the proposed equipment match.
Are rebates available?
Qualifying heat pumps and homes may be eligible for current Ontario programs. Eligibility, approved model lists and funding can change, so we confirm the available incentive during the quotation process.
*Performance varies by model, matched indoor unit and conditions. Mitsubishi Electric states that Zuba Central units can operate down to −30°C depending on conditions. †When installed and registered by an MEQ-certified HVAC contractor; conditions and limitations apply. Efficiency figures are “up to” ratings from Mitsubishi Electric's current R-454B Zuba brochure. Always refer to the quoted AHRI-rated equipment match.
