How Often Should You Service Your Air Conditioner?

Air conditioning in London needs regular check‑ups to stay efficient, reliable, and safe. With busy lives and rising energy costs, knowing when to service your aircon helps avoid breakdowns and high bills. This guide explains best service intervals, what to expect during maintenance, and when to contact an AC technician in London.

 


Why Regular Service Matters for Air Conditioning in London

Regular maintenance of your air conditioning in London is not just a recommendation—it’s essential for the long-term efficiency, comfort, and safety of your system. Many London homeowners rely on aircon systems to maintain a comfortable indoor climate during warmer months, and even year-round for homes that use reverse-cycle air conditioning for heating. Without routine servicing, minor issues can go undetected and evolve into major, costly problems.

One of the biggest benefits of regular service is energy efficiency. When filters are clogged or coils are dirty, the system has to work harder to cool the air, leading to higher electricity bills and added wear on internal components. Servicing keeps the unit running optimally, saving both energy and money.

Health is another factor. Air conditioning units circulate air throughout your home. Dirty filters can distribute dust, pollen, mould spores, and other allergens. Regular cleaning helps maintain indoor air quality, which is especially important for households with children, the elderly, or anyone with respiratory conditions.

Finally, regular service preserves the lifespan of your investment. Well-maintained systems tend to last significantly longer. A qualified AC technician in London will not only clean the system but also identify parts at risk of failure, keeping you cool and stress-free. Many manufacturers also require routine maintenance to keep warranties valid.

 

 


How Often to Service Your Air Conditioning

Determining how often to service your air conditioning in London depends on several factors, including the system type, frequency of use, and the local environment. However, the general rule of thumb is to have your system professionally serviced at least once a year.

For most domestic units—particularly split systems used for summer cooling—a single annual service is usually sufficient. This visit should include filter cleaning or replacement, coil inspection, electrical safety checks, refrigerant level tests, and thermostat calibration. Spring is typically the best time for this, as it prepares your aircon for the summer heat before demand peaks for servicing appointments.

Homes using reverse-cycle systems for both heating and cooling should consider twice-a-year servicing: once in the spring, and again before winter. This ensures year-round reliability and performance. If your home is in a dusty area or near construction, more frequent maintenance may be required to keep filters and components clean.

It’s also important to handle simple tasks yourself, such as cleaning filters every 1–3 months and checking for visible blockages around the outdoor unit. However, more technical tasks should always be carried out by a qualified AC technician in London.

For commercial buildings or systems over 12 kW, TM44 inspections are legally required every five years. These reviews assess energy efficiency and compliance, helping property owners avoid fines and improve system performance.


 


 Signs You May Need Servicing Sooner

Watch out for these warning signs, which may require more immediate attention:

  • Reduced cooling performance
  • Rising energy bills
  • Unusual noises or odours
  • Water leaks near the unit
  • Frequent on/off cycles

If any of these occur, call an AC technician in London promptly to prevent further damage.

 


What Happens During a Professional Service

When you book with a reputable company like Arcas Air Conditioning, expect:

  1. Visual inspection of all components
  2. Filter replacement or washing
  3. Cleaning of indoor and outdoor coils
  4. Drain pipe clearing
  5. Refrigerant level measurement and adjustment
  6. Electrical testing of fuses, contacts, and wiring
  7. Thermostat and sensor calibration
  8. Performance check: airflow, temperatures, and noise levels
  9. Maintenance report with advice for future care

A professional service takes about 1–2 hours for split systems and longer for ducted installations. The result is fresher air, quieter operation, and reliable efficiency.

 

 


Tips to Maximise Your Air Conditioning Service

To keep your aircon in London running smoothly:

  • Set calendar reminders for filter cleaning every 1–3 months
  • Clear vegetation and debris near the outdoor unit
  • Use recommended refrigerants and maintain airflow
  • Book annual services ahead of summer to avoid delays
  • Choose a certified AC technician in London for all servicing

These habits reduce strain and help your system cool efficiently year after year.


Maintaining your air conditioning in London matters. Clean filters and annual professional check‑ups by a trained AC technician in London ensure efficiency, reliability, and longevity. Whether you service monthly, quarterly, yearly, or follow TM44 regulations, consistent care delivers comfort, lower bills, and peace of mind.
