How to Lengthen an AC’s Lifespan

Your air conditioner provides crucial cooling during the hot and humid summer season. To help your air conditioner run smoothly for many summers to come, be sure to provide it with regular AC maintenance and replace the air filter regularly.

During maintenance, your HVAC system professional will perform a range of tasks to ensure optimal performance and longevity. Cooling system maintenance typically includes the following steps:

Cleaning and Inspecting Coils

The evaporator and condenser coils can accumulate dirt and debris over time, hindering the heat transfer process.

Lubricating Moving Parts

The motor, fan, and other moving parts in your air conditioner require proper lubrication to minimize friction and reduce wear and tear.

Checking and Tightening Electrical Connections

Faulty electrical connections can cause system malfunctions or even damage the system’s internal components.

Inspecting and Cleaning the Condensate Drain Line

The condensate drain line removes moisture from the air conditioner. Over time, it can become clogged with algae, mold, or debris, leading to water leaks or drain pan overflow.

Checking Refrigerant Levels

Improper refrigerant levels can impact the cooling efficiency and overall performance of your air conditioner.

Average AC System Life Expectancy

While there are many factors that determine how long your air conditioning system will last, you can typically count on your AC unit for 15-20 years. Ultimately, how long your air conditioner will last depends on maintenance frequency, how often the system runs, the system’s make and model, and various other factors.

To help your system last for as long as possible, schedule routine maintenance on time. Ideal maintenance frequency depends on the type of system your home uses for cooling. Central air conditioning systems require maintenance once per year.

Heat pumps and ductless AC systems, on the other hand, require maintenance twice per year, as these systems also produce heating, meaning they run all year long.

Warning Signs to Replace Your Air Conditioner

Thankfully, when the time comes to replace your existing system, the air conditioner will likely begin to exhibit some signs before more serious issues develop. Pay close attention to your air conditioner and schedule AC replacement services if you notice any of the following warning signs:

  • Rising AC bills
  • Frequent repairs
  • The system is 15-20 years old
  • Uneven cooling or hot spots in your home
  • Excessive noise while running
  • Reduced indoor air quality
  • Leaks under the unit
