The Furnace Selection Guide

With various types of furnaces available, selecting the one that best fits your needs can be challenging. This guide aims to simplify that process, providing key information to consider when picking the furnace that will be fueling your comfort.

Understanding Different Types of Furnaces

Many people don’t clearly understand the difference between furnaces and HVAC systems. Essentially, your furnace is part of your HVAC system, which helps generate warm air, besides the air conditioner. There are many types of furnaces to choose from:

Gas Furnaces

Gas furnaces are among the most common types. They use natural gas, which is piped directly into the unit from your local utility provider. Gas furnaces are known for their efficiency and effectiveness in heating and are a popular choice in areas where natural gas is readily available.

Electric Furnaces

Electric furnaces use heating elements to warm the air and are typically more straightforward and cheaper to install than gas furnaces. They are a good option in areas where electricity costs are lower or where natural gas isn’t available.

Propane Furnaces

Propane furnaces operate similarly to gas furnaces but use propane as fuel, stored in tanks on your property. They are a viable alternative in areas without natural gas service and are known for their high efficiency.

Oil Furnaces

In some regions, particularly where other fuel sources are not readily available, oil furnaces are used. They require an on-site storage tank and regular deliveries of oil but can be a powerful source of heating.

Factors to Consider When Selecting a Furnace

  1. Efficiency Ratings

Pay close attention to the furnace’s efficiency ratings, such as AFUE (Annual Fuel Utilization Efficiency). Higher AFUE ratings mean better efficiency and lower long-term costs.

  1. Size and Output

Choosing the right size is crucial. A furnace that’s too large or too small for your space can lead to inefficiencies and discomfort. A professional HVAC assessment can determine the appropriate size for your home.

  1. Climate

Your local climate plays a significant role in your decision. For instance, in extremely cold regions, a high-efficiency gas or oil furnace might be more appropriate, whereas, in milder climates, an electric furnace could suffice.

  1. Cost

Consider both the upfront cost and the long-term operating expenses. While some furnaces might be cheaper to install, they could be more expensive to run and vice versa.

  1. Environmental Impact

For those concerned about their carbon footprint, consider the environmental impact of the furnace. Gas and oil furnaces emit carbon dioxide, while electric furnaces if powered by renewable energy sources, can be a more environmentally friendly option.

  1. Installation and Maintenance

Proper installation by a qualified professional is critical for any type of furnace to ensure safety and efficiency. Regular maintenance, including filter changes and periodic inspections, is essential to keep your furnace running smoothly and efficiently for years.

Upgrading Your Current System

When you’re ready to replace your old furnace, upgrading to a newer, more efficient model can bring significant improvements to your home.

Modern furnaces offer higher AFUE ratings, meaning they use fuel more efficiently, which translates into lower energy bills and a smaller carbon footprint for you. These newer models often include advanced features like programmable thermostats, giving you greater control over your home’s temperature and the potential for additional energy savings.

By upgrading, you also gain improved reliability and a reduction in repair needs, as new furnaces are less prone to breakdowns.

Additionally, newer models are designed to operate more quietly, enhancing the comfort of your living space. This upgrade is an excellent opportunity for you to assess and possibly upgrade your home’s insulation and ductwork, further maximizing the efficiency and comfort of your heating system.


Selecting the right furnace is a critical decision for ensuring comfortable, efficient, and cost-effective heating in your home. By understanding the different types of furnaces, considering factors like efficiency, size, cost, and environmental impact, and ensuring proper installation and maintenance, you can make an informed choice that meets your heating needs and aligns with your values.

Remember, the right furnace is not just about heating; it’s about fueling your comfort in a way that suits your lifestyle and budget.
