Advantages of Gas Furnaces: Efficient, Affordable and Safe.

Gas furnaces have several advantages for home heating, including more efficient and cost-effective heating. Heating with gas can produce heat quickly and reliably, reducing the need for constant maintenance and repair.

With a gas furnace, you’ll never have to worry about power outages or running out of fuel, making gas an ideal choice for cold climates. Gas furnaces also tend to last longer than other types of heating systems. They require less maintenance and are easy to operate, making them a convenient choice for homeowners.

Whether you’re looking to save money on your energy bills or increase the lifespan of your heating system, a gas furnace is always a reliable choice.

Advantages Of Gas Furnaces

Gas furnaces have become increasingly popular due to their high efficiency, affordability, and safety. They are now the preferred choice over electric and oil furnaces for heating homes. In this section, we will dive deeper into the advantages of gas furnaces and understand why they are the best option for most households.

High Efficiency

Gas furnaces are highly efficient when it comes to heating homes. They use natural gas to generate heat, which is then distributed throughout the house using ductwork. The efficiency of a gas furnace is measured by its annual fuel utilization efficiency (afue) rating, which indicates how much energy is used to produce heat.

Here are some key points related to the high efficiency of gas furnaces:

  • Gas furnaces have afue ratings ranging from 80 to 98 percent, which means that up to 98 cents of every dollar spent on heating goes directly to warming the home.
  • High efficiency equates to low energy consumption, helping to lower energy bills and saving money in the long run.
  • Gas furnaces require less maintenance than other furnaces, which reduces the risk of breakdowns, extends the lifespan of the furnace, and lowers repair costs.

Gas furnaces have a low upfront cost and are more affordable than electric and oil furnaces. Here are some key points related to the affordability of gas furnaces:

  • The cost of natural gas is lower than electricity and oil, which can result in significant long-term savings on utility bills.
  • Gas furnaces have a longer lifespan than other heating systems, up to 20 years or more, which means that homeowners do not have to replace them as often.
  • Installation of a gas furnace is simple and cost-effective, especially if the house already has ductwork installed.


Many people are wary about gas furnaces due to safety concerns, but in reality, they are safe and reliable heating options when installed and maintained correctly. Here are some key points related to the safety of gas furnaces:

  • Gas furnaces are equipped with numerous safety features, such as automatic shutoff switches, heat exchangers, and ventilation systems to ensure proper airflow and prevent carbon monoxide leaks.
  • Modern gas furnaces have advanced technology that reduces the risk of gas leaks and pilot light blowouts.
  • Gas furnaces are less prone to electrical malfunctions, reducing the risk of fires.

Gas furnaces are efficient, affordable, and safe heating options for homeowners. They require minimal maintenance, have longer lifespans, and provide a comfortable and warm environment for families.

Installing a gas furnace is not an easy task, and it should be done by professional technicians. A professional technician can ensure that the installation is done safely and correctly. Here are some key points to keep in mind when installing a gas furnace.

  • Hire a licensed technician: It’s essential to hire a licensed technician who has experience in installing gas furnaces safely.
  • Permits: Before installation, ensure that all necessary permits have been obtained and that the gas lines are inspected.
  • Size: Pick a furnace with the right size. A furnace that is too big or small can result in unnecessary energy consumption, creating an impact on your wallet.


Maintaining a gas furnace is vital to ensure that it functions correctly and lasts for a long time. Here are the key points to consider when maintaining a gas furnace:

  • Regular check-ups: Arrange annual check-ups with a professional technician to ensure your furnace is running efficiently
  • Clean filters: Dust and other particles are one of the leading causes of furnace malfunctions. Clean your furnace’s filters frequently.
  • Inspection: Have a professional technician inspect the furnace’s ventilation system, burners, and heat exchanger to check if they are running correctly.
  • Lubrication: If the furnace has moving parts. Lubricate the parts frequently.

Troubleshooting Common Issues With Gas Furnaces

It’s not uncommon for gas furnaces to develop problems over time. Here are common issues that require troubleshooting:

  • Furnace not warming: If your furnace isn’t heating, first verify that the thermostat has been set correctly. If the thermostat has been set properly and the furnace still doesn’t turn on, check the fuse, circuit breaker, and pilot light switches.
  • Ignition issues: If your heater won’t turn on, make sure the pilot light is on and working. If the pilot light isn’t on, turn it on manually or call a technician.
  • Strange noises: If you hear strange sounds, like banging or screeching, turn off your furnace and call a professional technician.
  • Excessive electricity bills: If your electricity bills increase significantly, it’s probably because your furnace is malfunctioning or not working correctly.
