At some point in the lifetime of your furnace, you will need to start thinking about a replacement. In addition to the type of fuel your furnace will use, you should also consider the clear advantages of a modulating furnace.
If you are accustomed to either an electric or oil furnace, you may find a gas furnace, whether traditional or modulating, is better for your needs. A gas furnace can be more expensive upfront than electric, but in most areas, gas will be less expensive than electric and more accessible than oil. The upfront costs associated with any gas furnace will be higher, not just for the system itself, but because of the installation of new gas lines in a residence that does not use gas. When comparing gas furnaces, modulating options are also more expensive than their traditional gas counterparts, but the significant savings will come in the utility bills.
When comparing a traditional gas furnace to a modulating furnace, the modulating option is more efficient. Modulating furnaces are essentially the variable-speed ACs of the heating world. Instead of continually turning on and off, they run for a longer length of time. The system regulates the amount of gas used based on your needs. If the weather is not terribly cold, the system may use less gas over a longer length of time, gently heating up your home. When the weather turns brutally cold, the system can use more gas. The level of accuracy of a modulating system means it does not use unnecessary fuel, thereby reducing your gas demand and saving you money.
Although a modulating system uses less gas to heat your home, it does not sacrifice comfort. Actually, you may find your home to be more comfortable. Depending on your home, you may find it is difficult to reach and maintain a comfortable temperature with a typical gas furnace. This is because the furnace turns on and heats your home until it reaches the preset temperature and then cuts off. Your home may feel hot, then once the system turns off, your home is back to feeling cold. With the longer, gentle heating of a modulating furnace, there are fewer temperature swings, which allows your home to stay at a pre-determined, comfortable temperature. Beyond the energy efficiency, the level of comfort you can achieve in your home makes a modulating system a good choice.
