The Ultimate Guide to Gas Furnaces

Are you in the market for a new furnace? With so many options available, it can be overwhelming to choose the right one for your home. One popular choice is a gas furnace, which uses natural gas to heat your home. In this guide, we’ll cover everything you need to know about gas furnaces, including their benefits, how they work, and what to consider when purchasing one, along with tips for furnace repair, furnace installation, and furnace maintenance.

What is a Gas Furnace?

A gas furnace is a type of heating system that uses natural gas as its fuel source. It is a popular choice for homeowners due to its efficiency and cost-effectiveness. Gas furnaces work by burning natural gas in a combustion chamber, which then heats up the air that is circulated throughout your home via a duct system.

Benefits of a Gas Furnace

There are several benefits to choosing a gas furnace for your home. These include:

Cost-effective: Natural gas is typically less expensive than other fuel sources, making gas furnaces a cost-effective option for heating your home.

Energy-efficient: Gas furnaces have a high energy efficiency rating, meaning they use less energy to produce the same amount of heat as other heating systems.

Reliable: Gas furnaces are known for their reliability and can last for up to 20 years with proper maintenance. Quick heating: Gas furnaces can heat your home quickly, making them a great option for colder climates.

Cleaner burning: Natural gas is a cleaner-burning fuel source compared to oil or wood, making gas furnaces a more environmentally friendly option.

How Does a Gas Furnace Work?

A gas furnace works by burning natural gas in a combustion chamber, which then heats up the air that is circulated throughout your home. Here’s a breakdown of the process:

The thermostat in your home detects that the temperature has dropped below the set temperature. 

The thermostat sends a signal to the furnace to turn on. 

The gas valve opens, allowing natural gas to flow into the combustion chamber. 

The gas is ignited by the pilot light or electronic ignition. 

The heat exchanger, a metal component in the furnace, heats up as the gas burns. The blower fan turns on and blows air over the heat exchanger, heating it up. 

The heated air is then circulated throughout your home via a duct system. 

Once the desired temperature is reached, the thermostat signals the furnace to turn off.

Components of a Gas Furnace

A gas furnace is made up of several components that work together to heat your home. These include:

Thermostat: The thermostat is the control panel for your furnace and allows you to adjust the temperature in your home.

Gas valve: The gas valve controls the flow of natural gas into the furnace.

Combustion chamber: This is where the natural gas is burned to produce heat.

Heat exchanger: The heat exchanger is a metal component that heats up as the gas burns and transfers that heat to the air.

Blower fan: The blower fan circulates the heated air throughout your home.

Duct system: The duct system is a network of tubes that distribute the heated air throughout your home.

What to Consider When Purchasing a Gas Furnace

When purchasing a gas furnace, there are several factors to consider to ensure you choose the right one for your home. These include:

Size

The size of your furnace is an important consideration. A furnace that is too small will struggle to heat your home, while one that is too large will cycle on and off frequently, leading to increased energy costs. It’s important to have a professional assess your home and recommend the appropriate size for your furnace.

Efficiency

The efficiency of a gas furnace is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. This rating indicates how much of the fuel is converted into heat. The higher the AFUE rating, the more efficient the furnace is. Look for a furnace with an AFUE rating of at least 90%.

Brand and Warranty

When purchasing a gas furnace, it’s important to choose a reputable brand with a good warranty. This will ensure that you have support if any issues arise with your furnace.

Cost

The cost of a gas furnace can vary depending on the size, brand, and features. It’s important to consider your budget and choose a furnace that fits within it while still meeting your needs.

Furnace Installation

Proper furnace installation is crucial for ensuring your gas furnace operates efficiently and safely. Hiring a professional for furnace installation can prevent common issues that may arise from improper setup, such as leaks or inefficient operation.

Gas Furnace Maintenance

To ensure your gas furnace continues to operate efficiently and reliably, it’s important to perform regular maintenance and know when to seek furnace repair services. This includes:

Changing the air filter: The air filter should be changed every 1-3 months to ensure proper airflow and prevent dust and debris from building up in the furnace.

Cleaning the blower fan: The blower fan should be cleaned annually to remove any dust or debris that may have accumulated.

Inspecting the heat exchanger: The heat exchanger should be inspected annually for any cracks or damage that could lead to carbon monoxide leaks.

Checking the gas valve: The gas valve should be checked annually to ensure it is functioning properly.

Professional tune-up: It’s recommended to have a professional tune-up your furnace annually to catch any potential issues and ensure it is running efficiently.

Conclusion

A gas furnace is a popular and cost-effective option for heating your home. By understanding how they work, what to consider when purchasing one, and how to properly maintain it, you can ensure your gas furnace continues to keep your home warm and comfortable for years to come. Regular furnace maintenance and timely furnace repair can significantly extend the lifespan and efficiency of your heating system.

Our experience with Ranger HVAC was great. Our ground level HVAC system crashed after 20 years in the middle of a heatwave, in 2022. We called and scheduled a appointment for an estimate on a new system, Mike came out and explained all our options and helped us to pick the best system for us and our home. He was very professional and thorough. The whole experience was great and we would recommend Ranger HVAC to our friends and family. The workers that came out and installed the system were extremely nice and cleaned up after they were finished and were very informative about the whole new world of smart HVAC systems. The office support kept us informed of all the visits and invoices were completed electronically. Update We were so satisfied with Ranger's customer service that, four months later, when our 2nd HVAC system in the attic crashed on the new year's eve, after 20 years, we called Mike to install a new one. We couldn't be more happy with the results. Jennifer and Rudy

My heating system stopped working and a good friend of mine advised to me reach out to Ranger HVAC. The company representative responded in a timely manner and the diagnostic indicated issue with my blower motor, which required replacement. Ranger HVAC team brought in a new motor and replaced it at precise scheduled time with no delay.

Ranger HVAC installed a new HVAC system at my house yesterday. The company did an excellent job communicating with me from the time I requested a free estimate to the morning they arrived on site. They were careful to cover all the traffic areas and wore shoe covers. A team of three, including Michael the leader, completed the install to my satisfaction. They were patient to answer all my questions. I selected Ranger HVAC based on their knowledge, fair price, and honesty. Michael, who gave me the estimate, spoke from experience, having been himself an HVAC technician. The company didn't try to sell me what I didn't need. I felt that the information I received could be trusted. And indeed they delivered as promised! I am very pleased with the install and I highly recommend this company. Thank you Ranger HVAC for a job well done!

I had my HVAC ducts cleaned by Ranger HVAC this past week and was so impressed by their work. I saw what a comprehensive process it is and I’m very pleased with the result. Staff always cover their feet when in your home and are very careful when removing and replacing the vent covers and moving their ladders and equipment around. Very fair price as well. Thanks to Sean, Kofi, and Paul for a thorough job well done. I have already recommended Ranger to a couple of friends and will be contacting Ranger for any future HVAC issues.

      He did a fantastic job cleaning and inspecting my commercial AC unit. He made suggestions that I was completely unaware of regarding how to improve circulation and air flow as well as how to minimise my use of electricity during the summer. Excellent rates and service. Once more, many thanks!

        He is the top in his field! Without having to be at 69 degrees, the AC functions better than before. Additionally, because the heater is so hot, we don't need to turn it up all the way, which saves us money.

        Customer

          The crew was excellent, and I'm glad I found them since they are nice, down-to-earth people who didn't try to upsell me on items I didn't need instead of telling me about innovations that would make life better for my allergic relatives. All Degree Comfort comes highly recommended.
