Now you can experience the year-round comfort, savings, quality and reliability you deserve. The secret behind Zuba’s superior heating capabilities is our efficient and patented Cold Climate Hyper-Heat (H2iTM) technology. Designed for the Canadian market, Zuba operates at 100% heating capacity at -15°C and continues to deliver exceptional heating performance when the outdoor temperature drops as low as -30°C* and beyond.

Heat Pump Language


What are Stages?

Stages describe the different levels of output from a heat pump. A two-stage heat pump will have high and low settings for different levels of demand, while a single-stage model operates at full blast whether it’s needed or not.


What Does SEER mean?

The Seasonal Energy Efficiency Ratio (SEER) is a calculation to determine the efficiency of air conditioning in a heat pump. In simple terms, the higher the SEER the more efficient your system will be.


What Does HSPF mean?

The Heating Seasonal Performance Factor (HSPF) is a heat pump’s heating version of SEER. The number represents the total heat output of a heat pump. In simple terms, the higher the HSPF the more effective the heat pump will be at heating your home.


What does dB mean?

dB is used to measure the loudness of sound, and heat pumps typically range anywhere from 52-75 sound decibels. The lower this number is, the less intense or softer sounding the outdoor unit will be.

What's the Best Heat Pump Brand?

This question is better asked – What is the best heat-pump brand for you? Carrier and Amana have great Hybrid systems that pair well with your existing furnace however, these systems are not geared toward colder temperatures. North American heat pump brands are best paired with natural gas systems where the cost of using backup heat is not a major concern. On the other hand, if your backup fuel source is oil or propane you’ll want to consider brands that offer cold climate heat pumps like Mitsubishi or Daikin. Cold climate heat pumps like the Mitsubishi Zuba operate at 100% heating capacity at -15°C and continue to deliver exceptional heating performance when the outdoor temperature drops as low as -30°C. When choosing a heat pump it’s important to clearly define your expectations and work closely with an expert to find you the system that fits your needs.

Are There Heat Pump Rebates?

Yes, the Green Homes Grant currently offers up to $5,000 for cold climate air source heat pumps and $4,000 for Energystar-certified air source heat pumps. Here are two of our favorite matchups:

You can scroll to the line number and view these matchups here:

How Much Does a Heat Pump Cost?

The cost to install a heat pump will depend on a few factors such as the size of your space, product performance, and the material requirements but that’s not the answer you’re looking for and luckily, we have data.

When taking an average cost of 20 add-on hybrid heat pumps installed in 2022 we get $6,324. Keep in mind that this average is limited to add-on hybrid heat pumps and in order to qualify for government rebates, central ducted and hybrid systems must always be paired with a matching furnace or air handler. If qualifying for government rebates is important, you will need to explore hybrid heat-pump and cold climate packages which will increase costs significantly.

What Warranty Does Comfort Hub Provide?

In most cases, we match the manufacturer’s parts warranty with an equivalent labor warranty. For example, Mitsubishi products have a standard 10-year parts warranty, and we match that with a 10-year labor warranty. This is our way of saying that we stand behind the products that we install.

Does Comfort Hub use Sub-Contractors?

Absolutely not, all technicians are fully licensed employees. Each proposal has a no sub-contractor guarantee, so you can rest assured that your products will be installed right the first time around with us – it’s what we do best after all.

Is Comfort Hub Partnered with Lowe’s?

Yes! From Kanata to Orleans we are the installation company for the Carrier/Lowes HVAC program. We’re still a locally owned and operated business, we just have an 800-pound-gorilla on our side.
