Air Conditioning Service & Maintenance in Bristol & the South West

Regular air conditioning servicing keeps systems operating efficiently, safely and reliably throughout the year. Clean coils, balanced refrigerant levels and clear drainage help prevent breakdowns, reduce running costs and maintain healthier indoor air quality. Whether your system supports a home, commercial environment or specialist space, structured maintenance protects both performance and equipment lifespan.

Controlled Climate provides professional AC servicing across Bristol, Bath, Weston-super-Mare, North Somerset, South Gloucestershire, Gloucestershire and surrounding South West locations. All work is completed by REFCOM-accredited engineers with more than 30 years of HVAC experience. We offer one-off servicing and planned maintenance programmes tailored to usage and equipment type, delivered in line with UK regulations and manufacturer guidance.

What does an AC service include?

Each service visit follows a detailed checklist to restore efficiency, identify developing issues and confirm safe operation. Our engineers carry out:

  • Filter cleaning or replacement
  • Coil cleaning for improved heat transfer
  • Refrigerant level checks and leak detection
  • Fan, motor and moving-part inspection
  • Electrical testing and control verification
  • Thermostat calibration and settings review
  • Condensate drain and pump inspection
  • Performance testing with a documented service record

Benefits of regular AC maintenance

Air conditioning units work continuously during warm and cold seasons, so gradual loss of performance is expected without routine servicing. Regular maintenance helps:

  • Reduce energy consumption and lower running costs
  • Extend equipment lifespan
  • Minimise unexpected failures and downtime
  • Improve indoor air quality
  • Maintain consistent temperature control year-round

For everyday care tips, our air conditioning maintenance guide provides simple, practical advice.
