How long do AC condensers last?

Like other household appliances, the lifespan of an air conditioner condenser is not fixed, but daily usage habits and maintenance determine how long it can last. Here are the key points:

I. Key Factors Affecting Lifespan

▸Basic Quality Sets the Course

Ordinary Home Models: Typically last around 10 years
Commercial/High-End Models: Solidly built models can last 15 years or more

▸Environment is Like a "Survival Test"

Coastal Areas: Salt spray corrodes metal parts → lifespan reduced by 70%
Near Dusty Construction Sites: Heat sinks become clogged with dust within six months → compressor overloaded

▸Usage Intensity is a Hidden Killer

Running 24/7 → like making someone work overtime without rest

II. Bad Habits that Accelerate Aging

▸Using the Outdoor Unit as a Storage Shelf

Flower pots and clutter blocking the air vents = "covering" the machine

▸Not Cleaning the Heat Sink for Three Years

Dust clumps up like a "cotton coat" → cold air can't escape and heat can't dissipate

▸ Running the Unit Despite Refrigerant Leaks

Compressor lacking refrigerant lubrication → like an engine running dry

▸Installing it in front of a west-facing cement wall

The unit gets extremely hot in summer → Accelerated Part Aging

III. Extending Lifespan

▸ Cleaning Techniques

Before Summer Each Year: After powering off, use a water gun to spray the heatsink at an angle (avoiding the circuit board).
Restaurants and Shops: Clean outdoor unit oil stains monthly → Installing a dust filter makes things easier.

▸ Lightening the Machine's Load

On hot days, turn on the fan for circulation before starting the air conditioner → Avoid hard-starting the compressor.
Temperature Setting: Maintaining 26℃ is better for the machine than frequent temperature adjustments.

▸ Early Handling of Abnormalities

Excessive outdoor unit vibration → Check if the fan screws are loose.
Slower cooling and dripping water → Most likely needs refrigerant top-up.

IV. Signals It's Time to Replace Your Machine

Frequent repairs: Three repairs in two years could buy half a new machine. Soaring electricity bills and poor cooling: Old machines consume electricity like water, new machines save on electricity costs and pay for themselves in three years. Rust-through casing and exposed wiring: Safety hazards outweigh usability. Still using R22 refrigerant: Discontinued for many years, repairs are exorbitantly expensive.
