If you’re new to furnaces, don’t worry—you’re not alone! Whether you’re moving into a new home or thinking about upgrading your heating system, there’s a lot to know about furnaces. In this beginner’s guide, we’ll break down the basics to help you understand the types of furnaces, choose the right one for your home, and safely get it started. Here’s everything you need to know to make an informed decision about heating your home.
What Are the Three Types of Furnaces?
Furnaces come in several varieties, but three main types dominate the residential market: gas, electric, and oil furnaces. Here’s a quick rundown on each:
- Gas Furnaces – These are among the most popular types of furnaces, especially in colder climates. They operate by igniting natural gas to create heat, which is then distributed throughout your home. Gas furnaces are known for being energy-efficient and relatively inexpensive to operate, though they do require a natural gas connection.
- Electric Furnaces – Electric furnaces are powered by electricity, making them ideal for homes without access to natural gas. They work by running electricity through heating elements, which then produce warm air. While they tend to be less expensive upfront than gas models, electric furnaces can lead to higher utility bills, particularly in regions with high electricity costs.
- Oil Furnaces – Oil furnaces use oil as fuel, which is ignited to generate heat. These are less common but can be an option in areas where gas and electric connections are unreliable or unavailable. Oil furnaces tend to have higher maintenance needs, as they require regular cleaning and fuel delivery.
What Kind of Furnace Do I Need for My House?
The right furnace for your home depends on several factors, including the climate, available energy sources, and your heating needs. In Tucson, AZ, and Albuquerque, NM, where winters are relatively mild, you may want to focus on energy efficiency rather than maximum heating output.
- Gas furnaces are a good choice if you have access to natural gas and want a balance between efficiency and cost.
- Electric furnaces may suit homes without gas access or in areas with lower electricity rates.
- Oil furnaces can be a good alternative for rural areas or for homeowners who prefer an off-grid heating option.

How to Start a Furnace for the First Time
Starting a furnace for the first time can be daunting, but it’s straightforward when you follow these steps:
- Check the thermostat – Ensure it’s set to “heat” and adjust it to the desired temperature.
- Power on – For gas furnaces, open the gas valve; for electric models, ensure it’s plugged in and the circuit breaker is on.
- Ignite – If you have a pilot light (common in older models), you’ll need to light it according to the manufacturer’s instructions. Modern furnaces often use an electronic ignition system.
- Listen and observe – Listen for the fan and burners to start up. Check for unusual sounds or smells; these could indicate a problem requiring professional attention.
What is the Basic Knowledge of a Furnace?
At its core, a furnace is a device that heats air and distributes it throughout your home via ducts and vents. The furnace relies on a thermostat to detect room temperature and cycle on and off as needed to maintain comfort. Regular maintenance, such as changing air filters and scheduling annual inspections, can keep your furnace running smoothly and efficiently.
Furnaces might seem complex, but with a basic understanding of how they work, choosing and managing one for your home can be simple.
