When Should I Schedule A Furnace Replacement?

There is no specific timeframe for furnace replacement since units will differ in quality and longevity. Most can last well over a decade with proper care. After ten years, homeowners may want to start saving up. Frequent breakdowns can be stopped once and for all by a new furnace installation.

What Are Furnace Replacement Signs?

You might need a heating system upgrade if you notice multiple symptoms like delayed ignition, inadequate heat, odd smells, worsening corrosion, and pilot light failure. Reduced energy efficiency is also a sign that you should replace your furnace. It manifests as increased energy consumption and rising monthly bills.

How Often Should I Replace My Furnace Filters?

An HVAC air filter will prevent dirt and dust from entering the system to protect indoor air quality. However, the surface will get clogged up over time. Home air filter replacement should be performed regularly as stated in the manufacturer’s manual. Check monthly and replace it when necessary.

How Do I Determine The Size, Or Capacity, Of A Furnace For My Home?

The correct furnace size can be found by considering multiple factors, including the total floor area, the ceiling height, the insulation, the orientation, the amount of shade from trees, and the regional climate.

How Long Will My New Furnace Last?

Furnace lifespan varies greatly from one home to another. Homeowners can expect their new installation to last over 20 years as long as the unit receives proper care. It should also be of the right size for your home. If unsure, go to an HVAC contractor and ask about sizing estimates.

What Is A Furnace’s AFUE Rating?

The Annual Fuel Utilization Efficiency ratio measures a unit’s heat production relative to its fuel consumption. What is a good AFUE rating? It should at least be 80% and ideally greater than 90%. Check how to find AFUE rating from your user manual. It’s usually printed on the faceplate.



Furnaces can be relied upon to provide warmth and comfort during winter for a long time. Their lifespan can even exceed two decades, but homeowners will need to do their part in maintaining the system. They should monitor the air filters and change them whenever necessary. They should also call in the professionals for annual tune-ups. This will include a comprehensive inspection and cleaning. Minor repairs will be performed when needed.

As for those who have an older unit, the possibility of getting a replacement may be considered. Frequent breakdowns, spiraling fuel consumption, poor performance, and extreme old age are all good reasons to get a new unit. Just make sure that the replacement furnace will be of the right size for the house. Manual J load calculations should be performed to arrive at the necessary heating capacity. A high-efficiency unit would be ideal.
