How Can I Tell When It’s Time to Replace My Gas Furnace?

Knowing when it’s time to replace a gas furnace isn’t always straightforward, especially in milder climates. However short the heating season is in the Panhandle, it’s still necessary to have an efficient and dependable heating system. If your furnace meets any of these conditions, you should consider replacing it sooner rather than later.

It’s over 15 years old: A furnace that reaches 15 years has likely reached the end of its lifespan. You can check the agHow Can I Tell When It's Time to Replace My Gas Furnace?e of yours by looking inside the door, where you’ll find the manufacturer’s name and the model number. The manufacturer should be able to tell you when the appliance was manufactured.

Low energy efficiency: As you look for the manufacturer’s information, you may also notice a label that discloses its size in BTUs (British thermal units), and the amount of fuel it converts to heat for your home, which is how furnaces are rated for energy efficiency. Its AFUE (annual fuel utilization efficiency) may be clearly stated, or you can divide its heat output by its BTU size. An older furnace with an AFUE of 80 will, in reality, have a much lower heat output than when it was first manufactured.

It hasn’t been maintained: If you don’t maintain your gas furnace regularly, you might experience more frequent breakdowns as your system ages. Neglecting professional maintenance forces your furnace to run when it’s dirty and out of adjustment, all of which can stress components. An HVAC pro give you an update on its condition during a routine furnace inspection.

Repair bills are adding up: If it’s costing more and more to repair your furnace each year, it’s probably time to replace it. Passing cold fronts can overwork an aging system, prompting an untimely breakdown. A new furnace will provide you with a warranty you can depend on for years to come.
