Our No-Pressure Sales Process

Many people don’t know this, but the largest furnace isn’t always the right one if your home is smaller. A furnace that’s too big will actually wear out sooner, because it’s always turning on and off.

Here’s how we ensure you get the right furnace for your home, not just the most expensive one:

In order to help you get the right furnace for your home, we send an expert technician to visit you. They learn your home’s measurements to ensure you get the right size furnace for your home and insulation level.


Your personal preferences also factor in to the decision.

For example, if you’re on a tight budget then a lower-priced furnace may be a priority. If you want lower gas bills, perhaps a more energy efficient furnace is for you. Some people may want the quietest possible operation, or are bothered by warmer and cooler spots around the house.

You’ll learn about all the options that make sense, and get one or more models recommended to you.

Our quotes are all inclusive. You’ll know the total price for the unit itself, related materials, installation, labour, permits, and any related work like venting. We even include removal and disposal of your old equipment.


There are absolutely no hard sell tactics or pressure. You also get plenty of time to review the quote, and we’re available if any questions come up.

In the end it’s our job to ensure you are happy with your new furnace for years to come.

Benefits of a New Furnace Replacement

It’s not always best to wait until your old furnace dies to get a new one.

If your furnace is more than 10 years old and repair bills are starting to add up, you should consider replacing it.

Why? As time passes and technology improves, residential furnaces become more reliable and more efficient.

Using a new, high efficiency furnace can give you a variety of benefits, including:

Up to 50% reduction in natural gas consumption.

Up to 70% reduction in electricity consumption by the furnace fan.

More peace of mind – a new furnace is less likely to break down suddenly.

Less fluctuation of temperature in the home.

Fewer cold and warm air pockets in the home.

Better humidity control and indoor air quality.

Quieter operation.

Safer operation.

More space in your basement or utility area.

When combined with a programmable thermostat, you can take advantage of maximum energy efficiency savings, especially when you have regular maintenance done.

Our heating system specialists would be pleased to match your needs with the right furnace.
