How Long Will My Furnace Last?

Several variables impact the life expectancy of your heater. The most important factor in determining the lifespan of your furnace is its energy source. Although gas and electric heaters have different lifespans, they share one key trait: the need for regular maintenance.

Furnace Lifespan Factors

No matter what powers your heating system, regular maintenance is the most effective way to extend its service life. Replace your air filter every 1-3 months, schedule annual service and preventative maintenance, and don't let poor performance last too long.

Staying on top of these HVAC basics can also improve energy efficiency and the indoor air quality of your home. If you notice changes in how effective and efficient your heater is, contact Daniel's to get ahead of any minor problems – before they become big ones!

3 Signs Your Heater May Need to Be Replaced

Depending on the age of your heater, you may be deciding whether to repair your existing unit or replace it with a more energy-efficient model. Older heaters exhibit some tell-tale signs that replacement may be the best course of action, including:

  • Loud noises – Rattling, popping, or other sounds coming from your furnace while in use may be symptoms of age-related failure. The causes of the noises can range from loose internal components, a damaged blower motor, or, for gas-powered heaters, even a loud boom caused by delays in the ignition.
  • Increased energy bills – Always account for energy rate fluctuations, but many old heating systems become more expensive to run over time. Older forced air heaters, for example, become less efficient with age, resulting in longer run cycles and increased energy expenditure.
  • Frequent repairs – Like most HVAC components, we only truly appreciate our heating system when it stops working. If you're repeatedly forced to call for emergency repairs, evaluate the estimated repair cost and consider the expense of installing a new unit. For forced air heating systems over 15 years old, replacing the old unit may be more cost-effective. If you’re looking to replace a boiler or furnace, consider a dual-purpose (heating and cooling) heat pump, which will cost less to operate and now comes with federal rebates and incentives.

What Is the Average Lifespan of a Furnace?

Boilers, furnaces, and heat pumps each have their own expected service life.

How Long Does a Gas Furnace Last?

Most gas furnaces last 10-15 years, regardless of manufacturer. Nearly half of all U.S. households use natural gas to heat their homes, so there's a good chance your family relies on a gas furnace to stay comfortable. Nearly two decades is a good return on investment for heating, but how long do electric furnaces last in comparison?

What Is the Life Expectancy of An Electric Furnace?

Electric furnaces last longer than gas furnaces by 5-10 years on average. Most homeowners can expect between 20-30 years of worry-free use with an electric furnace. Most manufacturers recommend annual preventative maintenance on electric furnaces starting no later than 10 years after installation.

What Is the Life Expectancy of a Boiler?

A gas or electric boiler will usually last between 10 and 25 years.

What Is the Life Expectancy of an Air-Exchange Heat Pump?

Since they perform double duty as your heater and your air conditioner, they typically last between 10 and 15 years.
