Domestic & Commercial Air Conditioning
Maintenance Services Leeds, Yorkshire

It is generally recommended that air conditioning units be serviced at least once every 12 months, but in commercial settings or areas of high usage, servicing every six months may be more appropriate. Leeds experiences a variety of weather conditions throughout the year, including hot summers and colder winters, which can put strain on your air conditioning system. Regular servicing helps identify wear and tear, detect any drop in performance, and prevent problems from escalating. In domestic homes, annual maintenance will help keep running costs down and ensure healthy air circulation, particularly during the warmer months when AC usage increases. In commercial buildings where air conditioning is used daily—such as offices, restaurants, retail outlets, and gyms—more frequent servicing ensures comfort, health, and legal compliance. Failing to carry out timely maintenance may invalidate manufacturer warranties, result in reduced energy efficiency, and lead to sudden breakdowns that disrupt your home or business. TDC can assess your system’s specific usage and environment and recommend an ideal maintenance schedule that ensures long-term reliability, safety, and cost-effectiveness. Booking regular maintenance with a qualified provider like TDC gives you peace of mind that your system will perform efficiently all year round.

A standard maintenance visit from TDC includes a thorough inspection and full servicing of your air conditioning system to ensure it is working at peak performance. Our engineers will begin by cleaning filters, coils, and other components to remove dust and debris that can reduce efficiency and airflow. We then check refrigerant levels and pressure, which is essential for effective cooling and system longevity. Electrical components and wiring are inspected to ensure there are no faults or safety risks. The condensate drain lines are flushed to prevent blockages that could lead to water leaks or mould growth. The airflow is tested and thermostat settings are checked and calibrated for accuracy. We also examine the overall system for signs of wear or potential future issues and provide a written report summarising the health of the unit. Any parts requiring replacement or repair will be flagged and recommendations provided. Our service includes both visual and technical assessments using advanced diagnostic tools. This level of care ensures your air conditioning unit is safe, energy efficient, and compliant with manufacturer requirements. Whether it’s a one-off visit or part of a planned contract, our service is designed to minimise downtime and maximise comfort and performance.

Our team understands the critical role air conditioning plays in business operations, and our contract clients enjoy peace of mind knowing their systems are always in expert hands.

There are several indicators that suggest your air conditioning unit may require servicing. Reduced airflow or uneven temperature distribution is often the first sign of clogged filters or blocked ducts. Unusual noises, such as grinding, hissing, or rattling, may point to loose components, motor issues, or internal damage. A spike in your energy bills can indicate the system is struggling to work efficiently, often due to low refrigerant levels, dirty coils, or general wear and tear. Foul or musty smells may be a result of mould or bacterial buildup in the system, which can affect indoor air quality and cause health issues. Visible leaks, excessive condensation, or water pooling around the unit are red flags that the drainage system may be blocked or malfunctioning. In some cases, the thermostat may stop responding correctly or fail to maintain the desired temperature. If the system short cycles (frequently turns on and off), it could be due to a faulty sensor or overworked compressor. These issues not only compromise comfort but can also cause further damage if not addressed. Regular maintenance helps catch these problems early, keeping your system reliable and reducing long-term repair costs.

Absolutely. At TDC, we frequently maintain air conditioning systems installed by other providers. Whether the original installer is no longer in business, you’ve moved into a property with an existing unit, or you're simply looking for better service, we’re happy to help. Our engineers begin with a detailed assessment of your current system to understand its age, make, condition, and any previous maintenance history. Once assessed, we tailor our maintenance approach to suit the system’s specific requirements. We are experienced in working with all major manufacturers including Daikin, Mitsubishi Electric, Fujitsu, LG, Toshiba, Panasonic, and more. Our servicing includes everything from diagnostics, cleaning, and component checks, to safety inspections and performance optimisation. If the system has been neglected or has a history of faults, we can recommend any remedial work required to restore full functionality. For businesses or landlords, we can offer ongoing maintenance contracts even if we weren’t the original installer. You don’t need to worry about paperwork from the initial installation — we base our service plans on the current condition and future needs of your unit.
