Debunking These Common Myths About Gas Furnaces

Home Saving Inc • June 10, 2022

Gas furnaces are the most cost-effective way of heating your home. This makes them one of the most preferred options for indoor heating. However, a few opinions regarding gas furnaces have cast doubt on the effectiveness of this heating method.


In order to understand if these doubts are based on facts or just myths, the experts at Home Saving Inc. have put together this article to address the most common ones and debunk those that have no truth to them. Continue reading to find out more! 


Myth 1: Gas furnace is the Most Expensive Heating System


Many people assume a gas furnace is expensive due to the high cost of installation involved. However, this form of heating is actually the cheapest. Installing gas lines is initially expensive, however, with gas furnaces, you won’t need to incur any high expenditures in the future. 


With gas furnaces, you also won’t need additional appliances to heat multiple areas within your home. 


Additionally, the cost of natural gas is cheaper compared to other energy sources such as electricity. This means that in the long run, gas furnaces serve as an economical and practical heating solution for residential as well as commercial properties. 


Myth 2: Gas furnaces will dry out Your Air


This myth arises from the fact that people compare gas furnaces to wet heat systems and boilers. However, Boilers and wet heat systems affect the moisture in the atmosphere differently than how gas furnaces do. 


Unlike wet heat systems and boilers, gas furnaces work completely differently and do not dry out the air.


Myth 3: Furnace Maintenance is Optional


Many people believe that these furnaces last forever. This is completely untrue; they are made to last for 15 to 20 years. And like every other system, they need to be checked and maintained routinely.


Call reliable HVAC contractors to check your system and detect faults before they turn into costly problems. These checks will prevent your system from breaking down unexpectedly and allow you to get repairs done when the fault is minimal and not as expensive to repair.


Regular maintenance also reduces any risk of fire hazards. All heating systems pose fire risks if they are not properly maintained. Many people are of the opinion that gas furnaces, in particular,  are more unsafe and more prone to fire hazards.


This is another myth that must be debunked. Modern gas furnaces come with built-in safety features such as limit switches. In addition to limit switches, gas furnaces also have pressure switches that get rid of excess gas from the combustion chamber before a flame in ignited.


If you hear weird sounds or realize that your system is not functioning as expected, call the experts to check and run a gas furnace repair if necessary. 


Myth 4: Cranking up the Thermostat will Heat Your Home Faster


Many people turn up their thermostats when they want to heat their homes faster and then turn them down when the desired room temperature is achieved.


This may seem like a good plan but furnaces do not work that way. Doing this will only make your HVAC work hard to heat the space and eventually cause the system to wear off quickly.


A system that has worn out leads to higher energy bills and costly repairs. Ideally, you should keep your thermostat at a regular temperature to heat your rooms evenly.
