FAQ

A dual energy heating system is a combination of two types of energy, typically a heat pump and a natural gas furnace. This allows you to use the most efficient energy source based on the outside temperature.

At temperatures above -12°C, using heat pumps is the most efficient and energy-saving solution. However, when the temperature drops below -12°C, the demand for electricity increases. This reduces the cost-benefit ratio of the heat pump. The natural gas furnace automatically takes over, providing powerful and affordable heating.

The heat pump has priority for heating. However, when conditions require, the furnace takes over to ensure optimum efficiency.

A heat pump provides softer, diffused air and a slower rise in temperature, with a range of 96 to 100°F. A furnace provides warmer air, from 100 to 121°F. Both systems provide efficient heating, but the heat pump is more cost effective.

Electricity is billed at $0.08 per kWh. In dual energy mode, the amount drops to $0.04 per kWh as long as the temperature stays above -12°C. Below that temperature, the cost increases to $0.27 per kWh. Throughout the year, using dual-energy is much more economical.

Installing a humidifier improves the comfort of your home by maintaining optimal humidity levels. If the air is too dry, it can be uncomfortable to breathe and can cause damage to your furniture, resulting in cracks. Conversely, air that’s too moist encourages the growth of bacteria. A humidifier helps you find the right balance for a healthy, comfortable atmosphere. 

In addition, properly humidified air retains heat better, which can reduce your heating costs.

We recommend maintenance of your humidifier once a year, before the heating season, towards the end of autumn. This includes replacing the salt cartridge, which is essential to maintaining the unit’s performance. A worn salt cartridge can reduce the humidifier’s efficiency and promote the formation of scale.

We recommend changing the filter every 3 to 6 months, although this may vary depending on the environment. The presence of pets, children, or high activity levels can accelerate filter clogging. If the filter appears dirty or has changed color, replace it to prevent damage to your equipment.

Filters vary in thickness, quality, and size. Below are a few examples:

MERV 8-9 filters (standard): Catches particles the size of a pencil lead.

MERV 11 filters: These high-performance filters capture particles smaller than the tip of a needle.

Choose the right filter for your furnace. Too much filtration can restrict airflow and interfere with your furnace’s performance.

For new construction, an air exchanger is required because houses are highly insulated. An air exchanger helps to renew the air in your home. We recommend its use in the fall, spring and winter, unless the weather is cold.

It’s not advisable to use an air exchanger in the summer when a central air conditioner is installed. The exchanger will exhaust the indoor air and draw in warm, humid outdoor air, which is counterproductive.

Care must also be taken when operating an air exchanger in winter. Although it’s necessary to refresh the air, the exchanger can expel the warm air you’ve paid for, increasing your heating costs.

A smart or programmable thermostat is recommended for residential central heating systems. It allows the desired temperature to be maintained and provides the ability to schedule temperature changes at different times of the day, for example, 19°C at night and 21°C during the day. This can save energy if the difference between the programmed temperatures is small.

An air conditioner is primarily used to dehumidify and refresh the air in your home, whether it is a central or wall-mounted system. A heat pump, on the other hand, is basically an air conditioner that helps heat your home during cold weather. Note that in Quebec, it is prohibited to heat only with a heat pump.
