Plumb London Air-Conditioning Services

For offices, meeting rooms, retail units and managed buildings, air-conditioning is not a luxury, it affects staff comfort, air quality and, in the case of server and comms rooms, the reliability of equipment. The cost of a reactive emergency repair after a full failure almost always exceeds the cost of planned, preventative maintenance. We work with businesses and managing agents to keep systems serviced, document their condition, and schedule any disruptive works around occupancy so your team is affected as little as possible.

When a system is noisy, underperforming or has failed, we investigate before we recommend. Where a fault is hard to trace, or a unit is installed somewhere that prevents proper inspection, we take a methodical, phased approach: diagnose accurately, report, and give you an evidenced choice between repair and replacement rather than guesswork.

  • A commercial air-conditioning service and diagnostic investigation in De Beauvoir, where we serviced a four-unit Mitsubishi Electric system and ran a controlled, F-Gas-compliant condenser diagnostic across two phases.
  • A full commercial air-conditioning replacement for Sunnamusk London in Whitechapel, delivered with full RAMS and TAPS documentation and minimal disruption to a working retail premises.
  • A residential air-conditioning leak repair in Battersea, tracing and permanently resolving a condensate fault that a previous installer had left unfixed.
  • A split system installation and condensate repair in Chiswick, combining a new Worcester Bosch kitchen system with a high-level fault repair on an existing Samsung unit, attended by our head commercial air-conditioning engineer.

Air-conditioning refrigerants are regulated under F-Gas legislation, and only suitably certified engineers may handle them. All refrigerant recovery, pressure testing, evacuation and recharging is carried out to those requirements, using certified recovery equipment and the correct refrigerant type and quantity for the system. This protects you legally, protects the equipment, and protects the environment.

For most systems, an annual service is the minimum we recommend; higher-occupancy or continuously running systems often benefit from twice-yearly servicing. A service typically covers cleaning of filters and accessible components, inspection of coils and condensate drains, checks of refrigerant pipework and electrical connections, and testing of overall performance and operating temperatures, with every observation reported to you in writing.

We work with leading air-conditioning manufacturers, including Mitsubishi Electric, Daikin, Toshiba and Worcester Bosch, and maintain established manufacturer relationships across our heating and climate-control work. All refrigerant work is carried out by fully certified engineers, and our team brings the same diagnose-first approach to air-conditioning that we apply across every trade.

Manufacturer warranties on new systems vary by brand:

  • Daikin, 3 years, applied automatically with no paperwork required
  • Worcester Bosch, 5 years

We’ll confirm the exact warranty terms for your specific system at quotation stage.

Regular maintenance extends equipment life, protects efficiency, and catches small faults before they become expensive failures. A properly serviced and documented system:

  • Reduces the risk of costly emergency repairs and unplanned downtime
  • Maintains manufacturer warranty validity
  • Improves air quality and occupant comfort
  • Protects the reliability of server and comms room equipment where applicable

We understand that most air-conditioning work takes place in occupied homes or working commercial premises. We coordinate disruptive works, such as refrigerant recovery, around your operations or household routine, and communicate clearly in advance about what to expect on the day.

  • A trusted property specialist, family-run in London for over 35 years
  • Honest, transparent advice. We communicate the full scope of any works, including anything found beyond the original brief
  • A phased approach to complex works. You are never committed beyond what has been diagnosed and agreed
  • Clear quotations and written reports. You always understand what you are paying for, and why
  • Coordinated, considerate scheduling. We work around your operations to minimise disruption
  • Regulatory compliance. Refrigerant handled to F-Gas requirements, with documentation you can rely on

Frequently Asked Questions

An annual service is the minimum we recommend for most systems. Commercial systems in higher-occupancy or continuously running environments often benefit from twice-yearly servicing. Regular maintenance maintains efficiency, extends equipment life and prevents avoidable failures.

Cleaning of filters and accessible internal components, inspection of coils and condensate drains, checks of refrigerant pipework and electrical connections, and testing of overall performance and operating temperatures, with all observations reported to you in writing.

Air-conditioning refrigerants are controlled under F-Gas regulations, which require that only certified engineers, using certified equipment, recover and handle them. This keeps the work legal, safe and environmentally compliant.

Yes. We carry out methodical fault diagnosis, locating the underlying cause before recommending works. Where a unit cannot be properly assessed in place, we will advise on what is needed for an accurate diagnosis rather than guessing.
