AC Spare Parts in Saudi Arabia: Every Part Explained

Introduction

It’s August in Riyadh, 3 pm, and the split AC in the bedroom is blowing lukewarm air. The outdoor unit hums but the fan won’t spin. The technician opens the cover and says one of two things: “the capacitor is gone” or “the compressor is finished.” The difference between those two sentences can be fifty riyals or several thousand.

This guide covers AC spare parts in Saudi Arabia part by part. For each one you get:

• What it does
• What it’s called at the counter: Arabic shop names like kabastir, dinamo and board are given in brackets, because that is what you will hear
• How to tell it has failed
• What you must match so you don’t make a second trip

It works for split, window and central systems, and for homeowners, HVAC technicians and facility managers alike.

Why Buying AC Parts in Saudi Arabia Is Harder Than It Looks

• The heat is relentless. In Riyadh or Al-Ahsa an AC runs for months without a break. With outdoor temperatures near 50 °C the outdoor unit works at full load. That cooks the capacitor (كباستر), pits the contactor (كونتاكتر) and wears out the bearings of the fan motor (دينمو).
• Dust is constant. After a sandstorm the condenser coil clogs, head pressure climbs, and the compressor trips on its overload. Owners often think the AC is “finished” when it isn’t.
• Too many brands. LG, Gree, Samsung, Midea, Zamil, Trane, Carrier… each has its own motor sizes, boards and remotes. A 10-year-old model often has no OEM parts left and needs a spec-matched replacement.
• The technology moved on. Inverter units and R410A/R32 refrigerant are now standard under energy-efficiency rules. The board is now the second most expensive part after the compressor, and the wrong refrigerant or oil can’t be undone.
• Counterfeits are common. A capacitor labelled 45 µF that measures far less, or a refrigerant cylinder that is underweight. You only find out after installation.

AC Spare Parts by System Type

Split AC Spare Parts: What Each one Does and How its Fails

Part (Saudi shop name)	What it does	Failure signs	Match before buying
Compressor (كمبروسر)	Pumps refrigerant; no compressor, no cooling	Hums but won’t start, trips after minutes, breaker trips	Capacity (12/18/24k BTU…), refrigerant, voltage and phase, rotary/scroll/reciprocating
Capacitor (كباستر)	Gives the compressor and fan their starting kick	Swollen top, oil leak, fan only turns when pushed	Exact µF, voltage (370/450V), single or dual (35+5)
Fan motor (دينمو)	Cools the condenser / blows air indoors	Fan stopped while compressor runs, bearing noise, burnt smell	Watts/HP, RPM, rotation, shaft size, 60 Hz
Contactor (كونتاكتر)	Switches the outdoor unit on and off	Outdoor unit never starts or never stops, black pitted contacts	Amps (25–30A for splits), coil voltage (24/220V)
Thermostat & sensors (ثرموستات)	Decides when the AC cycles	Never cuts off, or cuts off too early, error code	Sensor resistance (e.g. 10K), plug type, wiring for wall units
PCB / control board (بوردة)	Runs fans and compressor from remote commands	No response to a working remote, blinking LED, burn marks	Printed part number; universal boards suit most non-inverter splits
Remote (ريموت)	User control	No response	OEM-style or universal; test first with new batteries and a phone camera
Refrigerant (فريون)	The cooling medium	Weak cooling, ice on the suction line, low gauge pressure	Type on the outdoor label (R22, R410A, R32). Never mix
Install materials (نحاس، عازل، تيب)	Copper pipe, insulation, tape, drain hose	Sweating pipes, leaks, water dripping indoors	Pipe sizes 1/4, 3/8, 1/2, 5/8

Technician’s rule: never condemn a compressor until you have checked the capacitor and contactor. A large share of “dead compressors” are a weak capacitor.

Split AC Spare Parts

• Outdoor unit:
  • Dual capacitor
  • Contactor
  • Fan motor and blade
  • Rotary compressor
  • Reversing valve on heat-pump models
• Indoor unit:
  • Blower motor
  • Control board and sensors
  • Louver (swing) motor
  • Drain tray and hose
• Inverter units: an outdoor inverter board and an electronic expansion valve. Match these by part number only, because universal parts rarely work.

The split brands we see most are LG, Gree, Samsung, Midea and Zamil.

Window AC Spare Parts

Window units are still everywhere in annexes, istirahas and staff housing. Common replacements:

• The double-shaft fan motor
• Selector switch
• Mechanical thermostat
• Capacitor
• Plastic blades

Older models have no OEM parts left. A spec-matched replacement works if voltage, 60 Hz and shaft size match. A 50 Hz motor runs slower, overheats and fails early.

Central AC Spare Parts (Ducted and Package Units)

• Belt or direct-drive blower motors
• Condenser fan motors
• Filter drier and sight glass
• Solenoid and service valves
• High/low pressure switches
• Wall thermostats
• Scroll or reciprocating compressors

A central compressor is never matched “by eye”. Match tonnage, refrigerant, and voltage and phase (usually 380–400V, 3-phase). Always replace the filter drier after a compressor change.

Refrigerant-Side Parts and SASO Requirements

• R22 is being phased out. New units run R410A or R32.
• Refrigerant-side parts are not interchangeable between gases. Pressures and oils differ for the compressor, expansion valve, filter drier and oil.
• Buy from a registered supplier. Electrical products sold in Saudi Arabia must meet the requirements of the Saudi Standards, Metrology and Quality Organization (SASO). Buy from a registered supplier who issues a VAT invoice and can tell you where the part comes from.
• Poor parts cost more than the part. They fail early and raise the power bill, because the AC runs longer to reach the same temperature.

AC Spare Parts by City: What Changes Regionally

Region	What stresses the AC	Most-needed parts
Riyadh & Qassim	Extreme heat, dust and sandstorms	Capacitors, contactors, outdoor fan motors, coil cleaner
Jeddah & Makkah	Year-round humidity	Drain hoses and pumps, coil cleaners and disinfectants
Dammam, Khobar, Jubail	Humidity and salt air	Contactors (pitting), coil coatings, fan motors
Khamis Mushait & Abha	Milder climate, heating and cooling use	Same core parts plus reversing valves

Cool.sa has branches in Riyadh (Ghirnata, Baalbeck St and Yarmuk) and in Khamis Mushait (Atud), and delivers across the Kingdom.

How to identify the Right Part Without OEM Manual

Part	Where the data is	What to photograph or note
Capacitor	Printed on the can	µF (e.g. 35+5) and voltage
Fan motor	Metal nameplate	Watts, RPM, voltage, 60 Hz, shaft size
Control board	Sticker or printed number	Part number plus photos of both sides
Compressor	Data plate	Model, refrigerant, voltage and phase
Whole unit	Outdoor unit label	Brand, model, capacity

For technicians: don’t guess on a TXV or EXV. The wrong valve floods the compressor with liquid or starves it. Measure superheat and subcooling before and after.

AC Down? Don’t Lose Days Haunting For a Part

Common Problems Technicians and Contractors Face Sourcing AC Parts in Saudia Arabia

• Wrong voltage or frequency: 50 Hz parts that last a few weeks.
• Dealer lead times: commercial parts can take weeks while the building has no cooling.
• Counterfeits: fake capacitors or refrigerant mean a second visit and a lost customer.

Cool.sa sells AC and refrigeration spare parts, wholesale and retail, with clear part numbers and a VAT invoice on every order. Buy online or at the branch.

For Maintenance Companies: Keep Stock Instead of Buying Per Call-Out

A van stocked with common capacitor sizes, contactors and a refrigerant cylinder closes most calls on the first visit. Send us your monthly usage list and we’ll quote for quantity. Request a wholesale quote →

FAQ

Q1. Which AC spare parts fail most in Saudi Arabia?

Capacitors first, then contactors and outdoor fan motors, then boards and thermostats. Heat and dust are the main causes.

Q2. Where can I find an AC spare parts shop in Riyadh?

(Baalbeck St) and Yarmuk, plus Khamis Mushait (Atud). You can also order online with delivery.

Q3. Can I buy AC spare parts online in Saudi Arabia with delivery?

Yes, at cool.sa, with delivery to all cities in the Kingdom.

Q4. Do you sell AC and refrigeration parts wholesale?

Yes, wholesale and retail. Technicians and maintenance companies can send a parts list on WhatsApp for a quote.

Q5. Are aftermarket (non-OEM) AC parts reliable?

Yes, if they match the specs exactly (µF, watts, voltage, 60 Hz) and come from a known source. Counterfeits are the problem, not aftermarket parts.
