Domestic & Commercial Air Conditioning Maintenance Services Chester

It is generally recommended that air conditioning systems be serviced at least once a year for domestic properties, and twice a year for commercial premises. However, the ideal frequency depends on how often the system is used, the environment it operates in, and the specific type of unit installed. For example, a home unit used only in summer months might need just one annual service, while a commercial system operating year-round may benefit from quarterly check-ups. Regular servicing ensures optimal performance, better energy efficiency, and early detection of issues that could become costly if left untreated. At TDC, we tailor our service schedules to your property’s needs and usage patterns. Our engineers can advise on the best maintenance frequency after your first inspection. Keeping up with servicing also ensures your warranty remains valid and, in commercial environments, that you stay compliant with F-Gas regulations. If you're unsure when your system was last serviced, it's wise to book a maintenance check as soon as possible to avoid breakdowns or health risks related to poor air quality.

A standard maintenance visit from TDC is a thorough and professional service designed to ensure your system runs efficiently and reliably. During the visit, our qualified engineer will carry out a full inspection of the unit’s internal and external components. This includes cleaning or replacing air filters, inspecting the evaporator and condenser coils, checking refrigerant levels, and ensuring there are no leaks. We test all system controls, thermostats, and safety devices, as well as inspect electrical connections. For commercial systems, we also conduct compliance checks to meet F-Gas or TM44 requirements where applicable. Drain lines are flushed to prevent blockages or water overflow, and any obstructions in airflow are cleared. At the end of the visit, you'll receive a detailed maintenance report outlining the work completed, system condition, and any recommended repairs or efficiency upgrades. This proactive approach helps you avoid surprise failures and ensures your unit operates effectively, keeping energy costs down and indoor environments comfortable year-round.
