How Long Does An HVAC System Last?

Given the substantial investment that a heating or cooling system entails, it makes perfect sense to maximize its efficiency. The normal life of an HVAC system is between 15 to 25 years, but this number might vary greatly depending on the system’s characteristics and other factors. Even with routine HVAC maintenance and repairs, today’s best boilers, furnaces, heat pumps, including AC repair in Pearland, TX will eventually end their useful life.

Expected HVAC System Lifespan:

How long a heating, ventilation, and air conditioning (HVAC) system lasts depends on the system type. The typical lifespans of specific HVAC equipment are as follows:

  • Although the average lifespan of an air conditioner is 15 to 20 years, some may last ten years. Due to salt penetration, they typically only last seven to twelve years in coastal environments. Typically, air conditioners and heat pumps are replaced if the compressor fails or the condenser is severely corroded and leaking.
  • With regular upkeep, gas furnaces can last between 20 and 30 years or even longer. When a furnace’s heat exchanger begins to leak, it is frequently removed as it is one of the most critical and expensive components. Systems that are improperly maintained or of dubious quality may only survive ten years. However, oil furnaces often last between ten and fifteen years due to inefficient fuel maintenance.
  • Boilers have a lifespan between 20 and 35 years, significantly longer than furnaces. If the heat exchanger begins to leak, it is frequently replaced.
  • Depending on usage frequency, heat pumps can last between 10 and 20 years, with 15 years being the norm.
  • Heat pumps function similarly to air conditioners, but because they can also offer heat, they are often utilized for a more extended period each year. In coastal areas, heat pumps with a lifespan of seven to twelve years are also subject to premature failure.
  • Except for coastal regions, ductless mini-splits may supply heating and cooling and have a typical lifespan of 10 to 30 years.
  • Even though these are the most common life cycles for HVAC systems, many homeowners opt to upgrade their systems sooner. As the computer ages, its stability and functionality may decline, increasing maintenance and electricity costs.
  • Once a system is between 10 and 15 years old, the monthly energy savings from upgrading to a newer, more efficient model will cover the initial investment, especially if the existing system is inefficient or has significant problems.

Measures to Extend the Life of An HVAC System:

Frequent Filter Replacement:

Even though your HVAC technician should inspect your filters during the twice-yearly inspections or AC installation in Pearland, TX, the homeowner is ultimately accountable for this task. The average fiberglass or pleated filter used in houses has a 30-day lifespan and should be inspected regularly.

Utilize the "Auto" Setting on the Fan:

Most Dayton air conditioners have two fan settings: “auto” and “on” Some kinds of dual-speed fans offer a slower, more energy-efficient fan speed between heating and cooling cycles.

Cleanse the Ducts:

The ducts are an integral component of any HVAC system. They carry air from the outdoor unit to the indoor unit. Over time, many forms of debris accumulate in the ducts. This restricts the free movement of air.

Utilize Insulation:

Insulating your home effectively allows you to retain the heated or conditioned air. Your HVAC system can maintain the optimum temperature with less effort. Properly placed insulation can reduce your annual heating and cooling costs by up to 20 per cent. The ductwork of your HVAC system can also be insulated.
