Frequently Asked Questions

How much does it cost to Generator Repair in UAE?

The actual repair cost depends on how big your generator is, the brand, and what parts we need to replace. A simple visiting fee with basic troubleshooting starts from around AED 350 to AED 750. For big jobs like engine rebuilding or alternator rewinding, we will give a detailed quote after checking the machine.

How quickly can your emergency technician arrive at my site?

We have emergency dispatch teams working 24/7. Depending on your exact address in Dubai, Abu Dhabi, or Sharjah, our technician will usually reach your place within 2 to 3 hours after you confirm the call.

Can you provide a temporary backup generator while mine is being repaired?

Yes, absolutely. Since we are a premier generator rental company, we can easily send a rental generator from our own fleet to your site to keep your operations running while we fix your machine.

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

Our standard AMC package includes changing the engine oil and filters, checking the battery, radiator inspections, control panel testing, adjusting loose belts, and running full load tests. We have different packages based on how many hours your generator runs.

Why is my generator cranking but refusing to start?

This is a very common issue that usually happens because of flat starter batteries, air bubbles in the fuel lines, clogged fuel filters, or a stuck fuel solenoid. Our team can quickly find the exact cause and get it started.

Do you offer certified load bank testing services?

Yes, we do. We have our own load bank machines to test generators of all sizes. This test runs your generator at full power to verify that the engine cooling, fuel delivery, and electrical outputs are working perfectly.

How does hot weather affect generator operation in the UAE?

The intense summer heat makes it hard for generators to cool down, which can lead to overheating, low battery life, and lower power outputs. Our maintenance contracts are designed to make your cooling systems ready for the hot summer months.

Do you use genuine spare parts for repairs?

We only use original spare parts and high-quality lubricants. Doing this ensures your machine remains highly reliable, keeps the manufacturer warranty active, and makes your generator last much longer.
