Motor City residents — are the original AC units in these apartment blocks reaching the end now?

Short version: a 15-year-old split that needs regassing every summer is past the line — you're paying for a slow refrigerant leak plus the efficiency of a worn, possibly R22, unit, and over two summers that usually costs more than a new, far more efficient replacement. Replace the repeat offenders; keep and service the ones still holding gas and cooling well.

The repair-vs-replace rule I use (same as the general repair-vs-replace thread, applied to a whole community): needs gas yearly + 10+ years old + weak cooling = replace. A unit that just needs a service and a one-off part is worth fixing.

Why Motor City specifically feels this now: the blocks went up together, so the original condensers are all ageing together — you're seeing a community-wide replacement wave, not bad luck. Older units on R22 gas are the clearest replace candidates: R22 is phased down, costs more to top up, and those units are far less efficient than a modern one, so a new unit genuinely shows up on the summer bill.

Tenant or owner? In most UAE tenancies major AC repair/replacement is the owner's responsibility while routine servicing is the tenant's — so document the weak cooling and regas history in writing and put the replacement case to the landlord (a new efficient unit also protects *their* asset and cuts *your* bill). For a proper like-for-like swap, AC installation and replacement across Motor City is a straightforward job once the decision's made. Anyone here replaced and measured the DEWA difference?

Older-block owner and I'd say: if you own, stop nursing a yearly-regas unit — do the maths over two summers (regas + call-outs + the efficiency loss) and a replacement usually wins, plus you stop the annual "will it die in August" gamble. If you rent, the leverage is the written record: a unit that's needed gas three summers running is a documented fault, not a lifestyle issue, and that's the owner's to fix. Same conclusion the Mirdif older-villa crowd reached — communities age in waves.

Renter in an older block elsewhere — when I framed it to the landlord as "the unit needs gas every year and the bill's climbing, a replacement protects your apartment and I'll keep servicing it," they agreed to replace it. The new unit was noticeably quieter and the summer bill did drop. So it's worth the conversation rather than just absorbing the regas cycle. Get the weak-cooling and regas dates on paper first; that's what moved mine.
