Keep downtime to a minimum with our maintenance plans
Planned preventative maintenance by D & J Air Conditioning Services Ltd helps keep commercial and industrial systems operating efficiently, reducing disruption to offices, retail spaces, warehouses, and other workplaces across Manchester, Stockport, Warrington and throughout the North West.
We offer services through ongoing maintenance contracts or one-off visits, with plans tailored to suit your operational requirements and budgets. Since 1971, our maintenance support has focused on helping businesses maintain reliable heating and cooling performance throughout the year.

Tailored support for every environment
D & J Air Conditioning Services Ltd understands that regular maintenance is crucial for identifying issues like blocked filters, reduced airflow, refrigerant faults, and component wear before they lead to larger system failures. Our services encompass diagnostics, repairs, gas reclaim services, safe disposal of old units, and maintenance for both new and existing systems.
We also offer equipment relocation and practical advice tailored to your needs. In case of urgent issues, we provide a 24-hour emergency callout service, ensuring that our maintenance contract clients receive priority breakdown cover, reduced labour rates, and access to emergency engineer support. Engineers certified by Refcom and F-Gas carry out all our work.


Supporting system efficiency and workplace comfort
Many air conditioning systems require annual servicing to meet legal obligations, while some environments may require two or three maintenance visits each year depending on equipment use and conditions. Routine maintenance can help improve energy efficiency, reduce breakdown costs, extend equipment lifespan, and maintain comfortable working environments. Planned servicing also supports system reliability, helping businesses reduce unexpected downtime and maintain effective climate control.
