How Long Do HVAC Systems Typically Last?

HVAC systems do not come cheap. So it is only fair to use those devices until their maximum capacity. Most people don’t understand when is the right time to replace an HVAC system. If used beyond a certain point, top companies of air conditioning repair in Lawrenceville, Atlanta, Duluth, and Roswell GA, say that this could create several problems. 

In general, most HVAC systems will survive 15 to 25 years; however, technicians from the air conditioning service in Marietta say this estimate can be extremely varied depending on the kind of system and other contributing variables. Even with routine maintenance and repairs, even the most advanced boilers, furnaces, heat pumps, and air conditioners will ultimately fail. 


To help you further with the lifespans of different kinds of HVAC systems, here’s a detailed list – 


Some HVAC systems needs less AC repair Lawrenceville, Duluth, and Roswell, GA, while some need more. Their life span may also differ depending on what type of HVAC system it is. Although their necessities might be different, every HVAC device needs regular repair to keep them functioning. 


Air Conditioners   


The average air conditioner will last 15 to 20 years, though some may only last 10 years. The unit’s fit, amount of upkeep, and size should be the right size for the household are all essential aspects that contribute to longevity.

When the compressor fails, or the condenser develops significant corrosion and leaks, both air conditioners and heat pumps are typically replaced by air conditioning repair in Marietta.




Gas furnaces can last even 20 to 30 years or longer with adequate maintenance. Poorly maintained or of dubious quality, systems can last as short as ten years. A furnace is usually changed when the heat exchanger begins to leak. Professionals in this field say it is one of the most important and costly components. 


Heat Pumps 


Heat pumps are generally used more than other units like furnaces. This contributes to a shorter life span of heat pumps. Heat pumps can last somewhere in the range of 10 to 20 years, contingent upon how often they are utilized; in any case, according to air conditioner repair in Suwanee, GA technicians, 15 years is the normal life expectancy. 




Signs that indicate an old boiler is when the heat exchanger begins to leak. Boilers usually last around 20 to 35 years with good servicing and proper care.

These numbers may largely vary depending on how you care for your HVAC systems. Maintenance from air conditioning repair affects the life span of all systems.
