Air conditioning lifespan: how long does it last?
Air conditioning: 12 to 18 years on average, so around 15 years in normal household use. Regular maintenance routinely pushes past the top of that range.
A fixed split air conditioner lasts 12 to 18 years on average. Air-to-air heat pumps, built on the same technology, sit in the same range.
Above a certain output, these systems fall under the periodic inspection required in France by decree 2020-912 of 28 July 2020. The Ministry for Ecological Transition sets out its scope and frequency.
Filter cleaning is decisive: clogged filters cut efficiency, raise consumption and strain the compressor, the most expensive part of the installation.

The maintenance that extends its life
Clean the indoor unit filters
How often: every 1 to 3 months in season
Dust the outdoor unit and clear around it
How often: every 6 months
Professional check (leak test, refrigerant pressure)
How often: every 2 years
Check the condensate drain
How often: once a year
Repair or replace?
A refrigerant recharge or a control-board replacement stays worthwhile on an installation under 12 years old. A compressor failure past 15 years generally justifies replacing the whole system, current models being markedly more efficient.
Having an out-of-warranty air conditioner repaired by a QualiRépar-certified repairer in France entitles you to 25€ taken straight off the invoice. No paperwork, nothing to pay up front: the repairer deducts it from the total.

How long does air conditioning last?
Twelve to eighteen years for a fixed split system, provided you clean the filters regularly and have the installation checked by a professional every two years.
How often should air conditioning filters be cleaned?
Every 1 to 3 months during the season you use it. Clogged filters cut efficiency, raise electricity use and make the compressor work for nothing.
These figures are orders of magnitude, not guarantees. Published studies diverge depending on their method: consumer surveys, repairer data, or declared length of use. Maintenance, usage and water hardness often weigh more than the brand.
