Is it worth replacing an AC condenser?

Whether to replace the air conditioner condenser (outdoor unit) depends on the actual investment and long-term return. Here are some easy-to-understand criteria:

I. Prioritizing Repair

● Minor Issues, Major Impact

Fan not turning/capacitor failure → Repair for a few hundred yuan vs. replacing with a new unit costing tens of thousands
Slight leak in copper pipes → Repair by welding and adding refrigerant for under a thousand yuan

● The Machine is Still Young

Machines used for <6 years → Core components haven't aged
Original compressor is working normally → Repairing is more cost-effective than replacing
Example: Outdoor unit dented by hail but indoor unit intact → Replace the casing and continue using

II. Signals for Replacing

● Repairing a Car is More Expensive Than Buying One

Compressor failure → Replacement cost ≈ 60% of a new unit
Three repairs a year → Cumulative repair costs are enough to buy half a new unit

● Older Machines are Inefficient

Condensers >10 years old → Consume 40% more electricity than a new unit
Still using R22 refrigerant → Adding refrigerant once is equivalent to half a month's salary for a regular air conditioner

● Significant Safety Hazards

Outer casing rusted through, exposed wiring → Rainy days may cause electrical leakage.
Aging wiring may cause sparks, posing a fire risk.

III. Calculate the economics:

IV. Hidden benefits of the new machine:

Noise upgrade: The new condenser is half the noise of the old machine.
Smart control: Remotely turn on via mobile phone; enjoy coolness as soon as you enter the house.
Warranty guarantee: Mainstream brands offer 6-10 years of warranty.
