Key Features

Cold Climate EVI Technology
Enhanced Vapor Injection keeps the compressor running at –25°C when standard heat pumps would shut down. The built-in base pan heater prevents ice buildup on the outdoor unit during freezing rain events.
Budget-Friendly Performance
The most affordable cold-climate heat pump we install. Kinghome delivers the core technology — inverter compressor, EVI, smart defrost — at a price that makes heat pump adoption accessible to more homeowners.
Whole-Home Ducted
Connects directly to your existing furnace ductwork. No wall units, no interior renovation. The outdoor condenser replaces your AC and adds full heating capability through the ducts you already have.
Rebate Eligible
Qualifies for Ontario HRSP heat pump rebates. Combined with the KU's low purchase price, the effective cost after rebates makes heat pump adoption a no-brainer.
Quiet Operation
The outdoor unit runs at 58 dB(A) — similar to a normal conversation. The inverter compressor ramps up and down smoothly rather than cycling on and off, reducing noise and wear.
10-Year Compressor Warranty
Kinghome backs the Ultranixx KU with a 10-year compressor warranty and 5 years on parts when professionally installed by a licensed contractor. H&C handles all warranty registration.

Why Kinghome

Maximum Value, No Compromises

Canadian-Focused Design

Kinghome designs its Ultranixx line specifically for the Canadian market. The KU cold-climate model includes EVI compressor technology, pan heater, and smart defrost — features that matter in Ontario winters.

Professional Installation

H&C's licensed technicians are trained on Kinghome systems. Proper refrigerant charging, airflow balancing, and duct sizing are critical — we get it right so your system performs as rated.

Financing Available

Already the most affordable cold-climate option, the KU becomes even more accessible with flexible monthly payments. Combine financing with rebates for the lowest possible out-of-pocket cost.

Not Sure Which Size
Is Right for Your Home?

Sizing a heat pump correctly is critical — too small and it can't keep up, too large and it short-cycles. Our licensed technicians perform a free heat-loss calculation and recommend the right size for your home.

FAQ

Frequently Asked Questions

What is Kinghome and are they reliable?
Kinghome is a Canadian HVAC brand that designs heat pumps specifically for the Canadian climate. Their Ultranixx line uses proven inverter compressor and EVI technology. H&C has installed hundreds of Kinghome units across the GTA with excellent reliability and customer satisfaction.
What's the difference between the KU and KD models?
The KU (Ultranixx Cold Climate) includes Enhanced Vapor Injection technology for heating down to –25°C — it's designed as a primary heating source. The KD (Ultranixx Standard) is a more affordable cooling-focused unit rated to –15°C, best suited as a supplement to an existing furnace or for milder heating needs.
How does the price compare to Mitsubishi or Midea?
The Kinghome KU is our most affordable cold-climate heat pump — typically 30–40% less than comparable Mitsubishi systems and 15–20% less than Midea. You trade some brand recognition for significant cost savings while still getting the core cold-climate technology you need.
Does this replace my furnace?
The KU can serve as your primary heating source in most Ontario homes. Many customers keep their furnace as backup for extreme cold snaps (below –25°C) — this hybrid setup gives you maximum efficiency most of the year with a safety net for the coldest days. H&C can configure the system either way.
What government rebates are available?
Ontario's Home Renovation Savings Program (HRSP) pays $500/ton (up to $2,000) for gas-heated homes and $1,250/ton (up to $7,500) for homes heating with electricity, oil or propane. Combined with the KU's low purchase price, the effective cost after rebates makes heat pump adoption extremely affordable. H&C handles all paperwork.
How long does installation take?
A typical ducted heat pump installation takes one day. H&C handles everything: placing the outdoor unit, running refrigerant lines, connecting to your ductwork and thermostat, electrical hookup, and system commissioning. We test every zone before we leave.

About Their Heat Pump

"Your technician, Cameron arrived right on time, diagnosed the issue with our air conditioning unit quickly, and had everything running perfectly again in no time. What impressed me most was how clean and respectful he was of our home shoe covers, drop cloths, the whole nine yards. I'd rate 6 stars if I could."
