I should have gotten a gas furnace rather than an electric furnace. There are a lot of pros and cons to the different types of furnaces. The reason I chose to go with electric is because a gas heater is not safe. If the heat exchanger cracks, carbon monoxide is released in the air quality. This poisonous gas is not able to be seen or detected. The home owners usually end up with carbon monoxide poisoning and have to be hospitalized. Also, a gas heating system can overwork itself and catch on fire. This is all due to a dirty air filter. Fire and poisoning sounded superbad. So I went with electric heating. For the most part, I love my electric heater. Yes, electric is way more expensive than gas. But, with my electric furnace I am getting 100% of the fuel I am paying for. With gas or even oil, the machine churns and burns it up. You are not getting all that you purchased. I also get faster and instant heating when I turn on my electric heater. The heating installation required no gas hook ups or a flue too. But, the downside to my heater is that it does not work in a power outage. My area frequently loses power and then I have no heating. I can’t turn on the heater without electric. It won’t provide heating with no electric. If I had a gas heater, it would not be affected at all. I get power outages many times a year. Every time it goes out I always curse my electric heater.
