Ensuring Optimal Comfort & Operational Efficiency: Our Comprehensive AC & Refrigeration PPM Services at ACL London
At ACL London, we understand that modern life, whether at home, in the office, or within commercial establishments, relies heavily on the unyielding performance of air conditioning and refrigeration systems. These sophisticated pieces of equipment are the silent workhorses that maintain comfortable indoor climates, preserve perishable goods, and ensure smooth business operations across the capital. From keeping your server rooms cool to maintaining the freshness of produce in supermarkets, their role is nothing short of critical.
However, like any intricate machinery, AC and refrigeration units are subject to wear and tear. Over time, dust, grime, and continuous operation can degrade their performance, leading to inefficiencies, costly breakdowns, and even health hazards. This is precisely why Planned Preventative Maintenance (PPM) isn’t just a recommendation; it’s an absolute necessity. At ACL London, we specialise in delivering tailored, comprehensive PPM and general maintenance services for all types of air conditioning and refrigeration systems, ensuring your units run at peak efficiency, extend their lifespan, and provide you with unwavering peace of mind.
In this article, we’ll delve into the profound importance of PPM, outline the meticulous process we follow, and shed light on the specialised chemicals we responsibly utilise to keep your systems in impeccable condition.
The Undeniable Importance of Planned Preventative Maintenance (PPM)
Many of our clients initially view maintenance as an optional extra, but we consistently demonstrate that PPM is, in fact, an essential investment that yields significant returns. For us at ACL London, it’s about shifting from a reactive “fix-it-when-it-breaks” mentality to a proactive, cost-effective, and strategic approach. Here’s why we consider PPM to be indispensable:

The Role of Specialised Chemicals in Our Maintenance
The effectiveness of our maintenance services often relies on the judicious and responsible use of specialised chemicals. These compounds are specifically formulated to address common issues in AC and refrigeration systems, ensuring a deeper clean and more lasting solution than mechanical cleaning alone. At ACL London, we prioritise the use of environmentally responsible and safe products, applied by trained professionals.
Here are the primary types of chemicals we employ:
- Coil Cleaners: These are perhaps the most frequently used chemicals. Over time, evaporator and condenser coils accumulate a stubborn layer of dirt, grease, biofilm, and oxidation.
- Alkaline Cleaners: Excellent for breaking down organic matter, grease, and dirt. They are generally safer for coils but require thorough rinsing.
- Acidic Cleaners: Used for tougher scale build-up and oxidation on coils, particularly on those exposed to hard water or corrosive environments. We use these with extreme caution due to their corrosive nature, ensuring proper dilution and neutralisation where necessary.
- No-Rinse Cleaners: Designed to evaporate without residue, often used for lighter cleaning or in situations where rinsing is impractical. We carefully select the appropriate coil cleaner based on the type of coil, the extent of contamination, and the material of the fins to prevent damage.
- Drain Pan Treatments: These typically come in tablet or liquid form and are designed to prevent the growth of algae, slime, and bacteria in the condensate drain pan. This inhibits blockages, foul odours, and potential water damage.
- Disinfectants and Sanitisers: For AC systems, especially those in sensitive environments, we may use specialist disinfectants to kill mould, mildew, and bacteria that can grow within the system, ensuring superior indoor air quality and preventing the spread of airborne pathogens.
- Leak Detection Fluids: While not cleaning chemicals, these specialised dyes or soap solutions are crucial for precisely locating refrigerant leaks, allowing our technicians to pinpoint the source and repair it effectively, ensuring F-Gas compliance and system efficiency.
- Refrigerants (Gases): While not a “chemical” in the cleaning sense, refrigerants are the lifeblood of cold systems. Our F-Gas certified engineers are trained to handle, recover, and recharge refrigerants responsibly, ensuring correct levels and compliance with environmental regulations.
We ensure that all chemicals are applied safely, handled according to manufacturer guidelines, and disposed of responsibly, always prioritising the health of your occupants and the environment.

Frequently Asked Questions (FAQs)
Q1: What exactly is PPM in the context of AC and Refrigeration? A1: PPM stands for Planned Preventive Maintenance. It’s a proactive approach to servicing air conditioning and refrigeration systems on a regular, scheduled basis to prevent breakdowns, optimise performance, extend equipment life, and reduce energy consumption, rather than waiting for a fault to occur.
Q2: How often should my AC or refrigeration units be serviced? A2: The optimal frequency depends on several factors, including the type of system, its age, usage intensity, and the operating environment. Generally, we recommend at least an annual service for residential AC units and often quarterly or bi-annual services for commercial AC and refrigeration units, particularly those critical to business operations or handling perishable goods. We’ll provide a tailored recommendation after an initial assessment.
Q3: Can I perform basic maintenance tasks myself, or do I always need a professional? A3: While basic tasks like cleaning external coils (if safely accessible) or regularly changing filters can be done by facility personnel or homeowners, comprehensive PPM requires trained and certified professionals. Our technicians have the specialised tools, knowledge of complex components, and F-Gas certification needed to handle refrigerants, diagnose intricate issues, and ensure compliance with safety and environmental regulations. Attempting complex repairs yourself can be dangerous and void warranties.
Q4: What are the common signs that my AC or refrigeration unit urgently needs maintenance? A4: Look out for: reduced cooling/heating efficiency, unusual noises (grinding, banging, hissing), strange odours (musty, burning), water leaks around the unit, increased energy bills, or the system frequently cycling on and off. For refrigeration, visible ice build-up or inconsistent temperatures are also clear indicators. If you notice any of these, contact us promptly.
Q5: What are F-Gas regulations, and how does ACL London comply with them? A5: F-Gas regulations are European Union laws that aim to reduce emissions of certain fluorinated greenhouse gases (F-gases) commonly used as refrigerants. These regulations mandate specific requirements for leak testing, record-keeping, and the qualifications of personnel handling these gases. At ACL London, all our engineers are fully F-Gas certified, ensuring that all our maintenance, repair, and installation work complies strictly with these crucial environmental and safety regulations.
Some customers require a more in depth service for such systems as AHU’s and hvac equipment, with requirements of changing fan belts, micro filters and deep coil cleansing.
