Many new homes use gas as a heating source, but Indianapolis’s older homes employ gas as a heating fuel, as well. However, a gas furnace installed in the 1970s wasn’t as efficient as the furnaces seen in modern homes. Over the years, these furnaces have improved from an annual fuel utilization efficiency (AFUE) rating of 65 percent to 97 percent, making them among the most cost-efficient, effective ways to comfortably heat a home.
When an Indianapolis-area natural gas furnace must be replaced, Northern Comfort Systems has the experience to help. Finding a unit that is ideal for an older home can be tricky, requiring specialized knowledge of a wide range of equipment dating back several decades. An experienced technician can maintain and repair systems to extend their lives for years, but in some cases, replacement is necessary.
While today’s high efficiency gas furnaces can cost more than regular models, homeowners often recoup the extra cost soon after installation. A 97 percent AFUE-rated furnace can provide significant monthly cost savings on a home’s or business’s utility bills.
A qualified gas furnace technician can recommend the best unit for the size and type of a building. A gas furnace cost must be balanced against the cost of operation each month to make sure it provides truly efficient heating and cooling for the size of the building.
In some cases, Indianapolis homeowners aren’t sure whether to repair or replace an aging gas furnace. In many cases, an old natural gas furnace can be replaced by a high efficiency gas furnace to provide a more comfortable heating experience. A technician will do a thorough view of a building’s system and make recommendations, but ultimately the decision rests with the homeowner.
While a gas furnace provides years of reliable service, when one fails, it often needs significant work. Older gas furnaces use a pilot light to heat the natural gas used to provide the heat source for a gas furnace. Modern furnaces trade the pilot light in for a glow stick made from silicone nitride. In systems with pilot lights, the thermocouple can malfunction, causing the pilot light to go out and requiring repair.
Because of its cost to repair, often a gas furnace can be replaced by a more modern system that provides increased efficiency. This not only saves money but also prevents the electric furnace from constantly breaking down when it’s needed most.
