Air conditioning servicing & repair in Sutton, Surrey and South London

If your air conditioning isn’t cooling properly, has started making unusual noises, or simply hasn’t been serviced for a while, RCB Plumbing can help.

Our air conditioning servicing & repair service

Our service is designed for customers who want a practical, straightforward approach. We work on domestic and light commercial air conditioning systems, carrying out servicing, fault-finding and repairs with care.

For servicing, we inspect the system, clean key areas where needed, check airflow, test operation and look for signs of wear or poor performance. For repairs, we start by diagnosing the problem properly rather than guessing. Once we know what’s wrong, we explain the issue clearly and talk you through the next step.

Some customers call us because their bedroom air conditioning isn’t cooling properly during summer. Others need help with a unit in a home office, shop, clinic or workspace. We’re used to working across a range of properties, from houses and flats in Sutton and Carshalton to business premises in Croydon, Epsom, Mitcham and the wider South London area.

Frequently Asked Question

How often should air conditioning be serviced?

For most domestic systems, annual servicing is a sensible option. Commercial systems or heavily used units may need servicing more regularly.

Can you repair air conditioning that is not cooling?

Yes. Poor cooling can be caused by several issues, including dirty filters, airflow problems, refrigerant faults, blocked drains or component failure. We’ll inspect the system and advise properly.

Why is my air conditioning leaking water?

Water leaks are often caused by blocked condensate drains, poor installation, dirty filters or drainage issues. It’s worth getting this checked before it causes damage.
