You may wonder why gas furnaces are so popular with so many homeowners. Now, with the appearance of super efficient condensing models, gas is even more popular than it ever was. These models can have a 90 - 95 percent fuel efficiency rate, which is 12 - 15 percent above the official requirements. In addition, some models don't even need a chimney.

Advantages of Gas Furnaces

All furnaces give off some degree of exhaust fumes. If you suffer from asthma, the experts recommend that you choose a two-stage furnace because the way it runs results in cleaner air. Two-stage furnaces operate at two levels: lower, or first stage when the weather is milder, and higher when it gets really cold.

The fact that these furnaces mostly run at the lower stage or first stage, means that they will not be creating more heat than is necessary and so won't waste fuel. They can also give you a more comfortable level of heat and lower energy costs. Another advantage with a two stage furnace is that when it runs on the first stage it will be quieter.

While controversy will probably always rage about which brand of gas furnace is better than others, the experts are unanimous about one thing. They all say that getting the best technician you can find to install your furnace will save you money in the long run. On the other hand, even the best, most expensive furnace can be rendered a heap of junk by bad installation.
