Frequently Asked Questions

How much does it cost to Generator Repair in Dubai?

The price to fix a generator depends on its size, the brand, and what part is broken. Small things like changing a sensor, a starter motor, or setting up the screen usually cost from AED 800 to AED 3,500. Medium jobs like fixing fuel pumps or radiator cleaning can cost between AED 4,000 to AED 9,500.

For very big work like rebuilding the engine or rewinding the alternator, it can go above AED 15,000. We always tell you the exact price first so you can decide comfortably.

How fast can a rental generator be delivered during emergency repairs?

We can bring and connect a temporary generator to your site within 2 to 4 hours after you call us. Since we have a very large stock of generators from 10 kVA up to 1250 kVA, we always have a machine ready for you. This backup unit will keep your business running while our team is busy fixing your main generator.

What size generator do I need for my commercial or industrial project?

Choosing the right size depends on the total power your machines need to start and run. Our experienced engineering team can visit your site to calculate this for you.

We look at your ACs, machines, lights, and computers to find the perfect size, usually between 20 kVA to 1500 kVA. Getting the right size is important so you do not waste fuel or overload the engine.

What are the main causes of generator failure in Dubai’s climate?

Most generators in Dubai fail because the high summer heat weakens the batteries, humidity spoils the fuel, and sand blocks the radiator. The extreme summer heat makes the engine too hot very quickly if you do not clean the radiator coolant regularly.

Also, fine desert dust blocks the air filters, which stops the engine from breathing clean air and causes quick wear and tear.

How often should a commercial standby generator be tested and serviced?

You should start and run your generator for 10 to 15 minutes once every week without any load just to keep the engine parts oiled. For a proper service, a professional team should change the filters and oil at least once every three months or after every 250 running hours. This regular care makes sure your generator works perfectly when the main power actually fails.

Do you provide genuine spare parts for all major generator brands?

Yes, we only buy and use 100 percent original spare parts from major brands like Perkins, Cummins, Caterpillar, and FG Wilson. Using original parts makes your machine run better, keeps your engine warranty safe, and helps your generator live a much longer life.

Can you handle synchronization for multiple generators at a single facility?

Yes, we can. Our electrical engineers are very good at designing and installing special panels so multiple generators can run together. This helps save diesel because the generators only turn on when you need more power, and it also means you always have a backup if one generator stops.

What is included in your Annual Maintenance Contract (AMC) for generators?

Our standard generator AMC includes four scheduled visits a year, changing engine oil and filters, checking batteries, tightening loose wires, testing safety switches, and giving you top priority when you call for emergency repairs. We also give you a complete check-up report after every visit, so you know your machine’s condition.
