Why regular air conditioning maintenance is essential

Ensure optimum performance

Regular servicing and maintenance are essential for all air conditioning and ventilation units to ensure they operate efficiently and effectively, whether for heating or cooling. For most air conditioning systems, we recommend maintenance every six months, but we are flexible to meet your individual needs and budget.

Maximise energy efficiency

A well-maintained AC unit uses less energy than a neglected one. Clean filters, proper refrigerant levels, and optimised airflow mean safe air quality, lower running costs and reduced carbon footprint. These are important considerations for property owners in Sussex and Surrey looking to cut energy bills and save money.

Prevent costly breakdowns

Regular maintenance catches small issues before they become expensive repairs. A simple filter clean or refrigerant top-up during routine servicing can prevent compressor failure, which can be costly to fix. Our preventive programmes eliminate concerns about system functionality, and we offer free advice on system care.

Extend system lifespan

Air conditioning units that receive regular professional maintenance typically last 15-20 years, compared to just 10-12 years for unmaintained systems. Protect your investment with scheduled servicing.

Legal requirements

If your air con system contains 3kg or more of refrigerant (most commercial systems and many larger residential units), UK regulations require annual leak testing by qualified F-Gas engineers. Mechcool’s certified team ensures your AC unit remains compliant.
