Why do ACs break down so often in Saihat and Qatif?
In the Eastern Province an air conditioner runs for long hours through summer heat above 45 °C, high coastal humidity and recurring dust. That combination strains the compressor, clogs filters and coils, and speeds up corrosion on outdoor units and copper lines.
That is why we recommend a check-up before summer, regular cleaning, and acting on early warning signs such as weak cooling or a noisier outdoor unit — a small fault today can become a failed compressor tomorrow.
What determines the cost of an AC repair?
The price depends on the cause of the fault, the AC type and capacity (for example 18,000 or 24,000 BTU), the refrigerant (R-22, R-410A or R-32), any part that needs replacing, and how easy the outdoor unit is to reach.
At Mousa Workshop we diagnose first and quote before starting, and we never replace a part without your approval. For typical market prices, see our AC service price guide on the blog.

Frequently asked questions
Why does my AC run but not cool?
The most common causes are a filter or coil clogged with dust, low refrigerant due to a leak, a failed run capacitor that stops the compressor, or a dead outdoor fan. Measuring pressure and current pinpoints the cause within minutes.
Do you repair the AC at home or take it to the workshop?
Most split and window AC faults are fixed on site. We only take a unit to the workshop for major repairs, and only after explaining why and getting your approval.
How long does an AC repair usually take?
Replacing a capacitor or clearing a drain usually takes under an hour. Leak repairs with a refrigerant recharge, or a compressor replacement, take longer depending on the case and part availability.
Do you work on all AC brands?
Yes — all the brands common in Saudi Arabia, including Gree, Zamil, LG, Samsung, Carrier, Midea, Haier, Toshiba and Daikin, both fixed-speed and inverter models.
Which areas do you cover?
