Keeping Your Home Warm with Furnaces

As temperatures continue to dip, having a properly working furnace is essential to staying warm and comfortable in your home. Furnaces come in different types and sizes, use distinct fuels, and offer various features. In this blog, you will learn the basics of furnaces, the different types available, their pros and cons, and what to consider when choosing the right one for your home.

Types of Furnaces 

There are four types of furnaces to choose from natural gas, propane, oil, and electric. Natural gas furnaces are the most common and use a network of pipes to supply gas to the burners. Propane furnaces are similar to natural gas furnaces, but they use propane gas instead. Oil furnaces use heating oil and are mostly prevalent in northeast regions. Finally, electric furnaces are typically installed in homes without access to other fuel types and are more expensive to operate. Each furnace type has its benefits and drawbacks, depending on your location and fuel preference.

Efficiency and Size

When choosing a furnace, consider its efficiency and size. Furnaces come with Annual Fuel Utilization Efficiency ( AFUE) ratings that indicate how efficiently the furnace uses fuel to produce heat. The higher the number, the more efficient the furnace. It's also essential to get the right size furnace for your home. A furnace that is too small won't be able to heat your home effectively, while one that is too large can lead to energy waste, higher bills, and poor temperature control.


Some furnaces come with additional features that affect how they heat your home. One of these features is a variable-speed blower that modulates airspeed depending on the temperature. Two-stage heating is another feature that allows furnaces to operate at low capacity to maintain a consistent temperature and high capacity for quick heating. A modulating furnace is the most advanced option, continually adjusting its fuel and air supply to maintain a precise temperature. These features give you greater control over how your furnace operates.

Maintenance and Repairs 

Regardless of what type of furnace you have, regular maintenance and occasional repairs are necessary to keep it working efficiently and prevent expensive breakdowns. Regularly changing filters, cleaning ducts, and scheduling professional tune-ups should keep your furnace in good shape. However, if you notice any issues, like strange noises or uneven heating, it's essential to get repairs as soon as possible to prevent more severe problems.


Furnaces vary in cost, depending on the type, size, and features. Gas furnaces are typically the least expensive, while electric furnaces can be more expensive. You should factor in the cost of installation, additional features, and energy efficiency when choosing a furnace. It's also essential to invest in a furnace that comes with a warranty to cover any repairs within its lifespan.
