Why Winter AC Maintenance Matters In London 2025
Many overlook their air conditioning system until summer, not realising that the system may also have the option to provide heating during the winter months. Regular maintenance during winter ensures your air conditioning unit provides healthy, energy efficient comfort all year round with summer cooling and winter heating.
Off-season servicing in particular can offer special benefits of winter servicing, helping prevent surprise breakdowns and maintaining a healthy air conditioning unit through winter.
London’s Winter Climate: What It Means For Your Air-Conditioner
London winters are milder than some, yet prolonged dampness and cold snaps increase strain on air conditioning systems, especially when performing as heat pumps.
Over time, these conditions can contribute to efficiency reducing issues (like clogged filters, leaks or frost build-up) that threaten both performance and longevity. As the capital urbanises and demands for modern air con rise, regular maintenance grows ever more essential—particularly for ageing or overworked AC systems.
Key 2025 F-Gas Regulations Impacting London AC Systems
From January 2025, important F-Gas regulations apply to London air conditioning installations. Notably, single split air con systems with less than 3kg of refrigerant and over 750 Global Warming Potential (GWP)—such as those using R-410A—are banned for new installations. This aims to push households and businesses toward lower-emission, sustainable refrigerants.
Owners of older, high-GWP AC systems should review their compliance and consider upgrades, as further phase-out restrictions and fines loom for non-compliance. For more information, see this regulatory update on global warming important refrigerants.
Refrigerant Options For Sustainability And Compliance
2025’s F-Gas changes are driving a shift to new-generation refrigerants like R32. R32 offers a much lower GWP, is more energy efficient, and helps reduce your carbon footprint in line with Net Zero targets. To better understand the new R32 gas benefits, homeowners and facilities managers should evaluate their current air-conditioning system and discuss replacement or retrofit options with certified engineers.
Cost Savings: How Off-Season Servicing Cuts Your Energy Bills
Booking your air conditioning maintenance during winter is often cheaper and quicker than in the busy summer months. Off-season servicing detects minor issues early, preventing costly repairs, reducing energy consumption, and maximising long-term savings.
Winter inspection also ensures your air conditioning unit switches to heating mode safely and efficiently, so you remain cosy through winter while reducing your air-con running costs.
Integrating Smart Controls & Off-Peak Tariffs
Today’s smart controls and thermostats make it easy to monitor and manage your air conditioning system. By linking your AC to a smart meter and using dynamic or static time-of-use tariffs, you can schedule operation to off-peak electricity hours—helping to cut bills and balance the national grid.
Consider automating your system for optimum efficiency and discover how to control your air-conditioning through your smartphone.
Step-By-Step Winter Maintenance Checklist
Protect your investment with this simple winter AC maintenance routine:
- Schedule professional air conditioning maintenance with certified engineers for optimal system efficiency and to detect hidden faults. Book your AC service now
- Clean or replace filters every 1–2 months for healthy, efficient airflow.
- Inspect and clear the outdoor unit of debris, dirt, leaves or snow; check for proper drainage.
- Check refrigerant levels and thermodynamic operation; low refrigerant can signal leaks or compliance issues.
- Test heating mode and thermostat for reliable comfort.
- Schedule a health check for heat pumps; see heat pump maintenance.
- Review insulation around the unit and consider proper insulation for optimising air-conditioning efficiency.
- Assess indoor air quality—book a test of indoor air quality.
- Keep a maintenance log for warranty records and regulatory needs.
- Arrange for repairs quickly on any unusual noise, odour, or drop in performance; see air-conditioning unit maintenance.
DIY Vs. Professional Service: Weighing Costs And Risks
While you can perform basic filter cleaning and keep the outdoor unit clear, most long term air conditioning maintenance should be carried out by professional, certified engineers to reduce the risk of costly system failures, warranty voids, and breaches of UK law.

Heat Pump Special Considerations For Colder Months
Heat pumps, an increasingly popular modern air choice for energy efficient comfort, need particular care in winter. Key steps include:
- Maintaining clear airflow around the outdoor unit.
- Regularly checking and cleaning filters and fans.
- Monitoring for ice or frost build-up.
- Using smart thermostats to avoid constant temperature changes that increase wear and energy consumption.

When To Repair, Retrofit, Or Replace Your AC In 2025
Wondering if your air conditioning installation needs attention? Consider replacing if:
- It’s using a now-banned refrigerant (e.g., R-22).
- It’s using a high GWP refrigerant (e.g., R407C, R410A)
- You experience regular faults or rising running costs.
- It’s more than 10–15 years old.
Retrofitting to comply with F-Gas and boost efficiency is sometimes an option, but for outdated or non-compliant systems, a complete system replacement is the smart, long term solution.
FAQs
