What Is Included In Repair and Servicing?

AHU Repair and Servicing

Every ventilation system has an AHU or Air Handling Unit. These units collect external air and room air, remove dust and other particles from the collected air, adjust the temperature and then supply comfortable and fresh air-conditioned air into the rooms through ducts. AHU servicing is essential to ensuring that heavy dirt build-up is removed.

AHU Repair & Servicing includes:

  • Carrying out checks to fan motors.
  • Fan belt replacement.
  • Cleaning coils.
  • Motor bearings checks.
  • And more.

We have vast knowledge and experience in supplying and maintaining air conditioning systems for schools, colleges, universities, city and local-based offices, retail stores, IT server rooms, restaurants and homes of all shapes and sizes.

Questions about AC installation

How much does an AC repair cost?
It depends on the fault and the parts required. We offer a fixed call-out fee and always provide a quote before any work begins.
Can you fix my AC on the first visit?
In many cases, yes. We carry common spare parts and aim to complete repairs during our first visit whenever possible.
What areas do you cover?
We operate across London, Kent, Surrey, Essex, Sussex and surrounding areas.
Is it worth repairing or should I replace?
We’ll give you honest advice. If a replacement is more cost-effective long-term, we’ll let you know — but we’ll always try to repair first where practical.
