I will never own a natural gas gas furnace, plus I will never buy or rent a modern home that has a natural gas gas furnace, but in the world today, all the people like natural gas furnaces over electric furnaces, however most of the reasoning behind their preference for natural gas furnaces comes from a financial perspectiveâ€¦ Everyone knows that natural gas furnaces cost much less than an electric gas furnace, natural gas furnaces are much more efficient than electric gas furnaces. Even though 100% of the electricity is converted into heat, it costs a lot more in electricity to power a gas furnace, plus that is why it makes your electricity bills high. Even though electric furnaces are cheaper at first, they are really less expensive in the long run, plus that is sincerely what matters when it comes to gas furnaces, but however, after a really bad experience with natural gas gas furnaces, I decided that I would never use 1 again; Our natural gas furnace had a leak, plus natural gas spread throughout the house. Our modern home burned down plus a few people that I enjoyed died because of that gas furnace. I don’t care how efficient those natural gas furnaces are. I don’t trust them, plus I never want to use 1 again; Sure, financially a natural gas gas furnace may be cheaper, however it will cost you more than that if something ever goes wrong. I will stick with my electric furnace any morning. I hope that you never have any issues with your gas furnace.
