Frequently Asked Questions

What is a high efficient furnace?

High efficiency is achieved through a secondary heat exchanger which makes the furnace more efficient. A secondary heat exchanger is where the extra heat is condensed to for more heat into the house before it goes outside to the atmosphere. In Canada, a rating of 92% is required for a furnace to be considered high-efficiency. 

What is the difference between high efficiency and standard efficiency furnaces?

As the name suggests, high efficiency furnaces use less fuel because they convert 90-97% of the energy from gas into heat, while standard-efficiency furnaces convert roughly 80% of the energy from gas into heat.

What is the difference between Single-Stage and Two-Stage Heating?

Single-stage: When there is a call for heat, the furnace uses 100% of the gas and 100% of the electricity to satisfy the heat call. Typically less efficient fan motor.

Two-stage: When there is a call for heat, the furnace will use 50% of the gas and 50% electricity for a preset number of minutes set by the furnace computer board, this can also be controlled by two stage thermostats. After the preset number of minutes have passed, it will start to use 100% gas and 100% electricity. The majority of heat calls will fall under the 50% usage depending how you set your thermostat. Typically more efficient fan motor.

When should I be changing my furnace filter?

Depending on the type of filter, you will need to change it every 2 months (4 inch filter) or every 3 months (5 inch filter). However, the best way to find out if your furnace filter needs to be replaced is by pulling it out and taking a look once a month. If it looks dirty and clogged up, then it’s time for a new filter.

Why is my system freezing up?

A common problem is that not enough air is getting past the inside part of the air conditioner. We recommend checking your filter before calling out a service tech. If you have a dirty filter, please change out the filter to a less resistant filter (something you can see through) and run the furnace fan to help thaw out that coil. Give it the day to unthaw.

What can I do when I have a cold spot in my house?

One solution is to run your furnace fan continuously (turn fan to “ON” on thermostat) to pressurize the house. This also helps with constant air movement and can eliminate your house feeling stuffy or stale.

Another solution is to install an Ecobee or Nest smart thermostat with room sensor. We can set up your new Wi-Fi thermostat to average out the temperature in your house.

When should I be covering my air conditioner?

Typically, you should cover your air conditioner during the colder months to keep snow and debris off the unit when not in operation.

What can I do myself to enhance my home’s air quality?

Get a home air filtration systems or air purifier. Some options available here.
