Natural Gas Furnace Buyers’ Guide

In our previous blog posts, we’ve explored various heating options, including propane furnaces and heat pumps. We’ve also discussed the importance of HVAC system add-ons like humidifiers and dehumidifiers to ensure optimal home comfort.


This time, we’re focusing on a popular and efficient heating solution: the natural gas furnace. We’ll cover everything homeowners and business owners need to know about this essential component of a comfortable indoor environment before investing in one.

What Are Gas Furnaces?

Gas furnaces are a popular choice for heating homes and businesses because they are efficient and cost-effective. They work by burning natural gas to produce heat, which is then distributed throughout the space via a system of ducts and vents.

Natural Gas Furnace VS Propane Furnace

When comparing propane and natural gas as fuel sources for heating, there are several factors to consider:


Natural gas is typically delivered through a pipeline, making it readily available in many urban and suburban areas. Propane, on the other hand, is stored in tanks and may be more accessible in rural areas where natural gas lines are not available.


Propane and natural gas costs can fluctuate based on market conditions and regional availability. Generally, natural gas tends to be less expensive than propane, making it a more cost-effective option for heating in areas where both are available.

Energy Efficiency

Both propane and natural gas furnaces can be highly efficient. High-efficiency models are available for both fuel types, with Annual Fuel Utilization Efficiency (AFUE) ratings that can exceed 90%.

Environmental Impact

Natural gas burns cleaner than propane, producing fewer greenhouse gases and pollutants. However, both are considered cleaner alternatives to heating oil or coal.


Both propane and natural gas are highly flammable, and safety precautions are necessary when using either fuel. Gas leaks can be dangerous, so it’s important to have functioning carbon monoxide detectors and ensure your heating system is maintained correctly.


Propane is stored in tanks that can be installed above or below ground. This requires space on your property and regular refilling. Natural gas is delivered continuously through pipelines, so there’s no need for storage.

Energy Content

Propane contains more energy per cubic foot than natural gas, meaning you’ll need less propane to produce the same amount of heat. However, this is typically offset by the higher cost of propane compared to natural gas.


Luckily, at Dynamic Heating and Cooling we offer financing options for our Greater Toronto Area clients.


The choice between propane and natural gas will depend on factors such as:

  • Availability in your area
  • Cost
  • Efficiency
  • Environmental considerations.


It’s important to weigh these factors and consult with a heating professional to determine the best option for your specific needs.
