Air conditioning is no longer just a luxury in the UK — it’s rapidly becoming a standard feature in both homes and workplaces, especially as summers become hotter and more unpredictable. Whether you’ve just had a unit installed or want to make sure your system is running efficiently, there are plenty of ways to improve performance and cut down on unnecessary energy use.
At Controlled Climate, we work with homeowners, landlords, and businesses across Bristol and the South West to provide expert air conditioning installation and service maintenance. In this blog post, we’ve compiled our top 7 tips to help you get the most out of your air conditioner, whether it’s for residential comfort or commercial cooling.
1. Replace Outdated Air Conditioning Units
Air conditioning technology has advanced significantly over the past decade. If your system is more than 10 to 15 years old, chances are it’s not running as efficiently as it could be. Older models often use outdated refrigerants, lack inverter technology, operate at lower energy efficiency ratings (SEER), and require more frequent repairs.
Newer systems are quieter, more powerful, and more environmentally friendly. They adapt their output based on demand, resulting in lower energy usage and more consistent comfort. If your unit is starting to struggle or you’ve noticed higher electricity bills, it may be time to consider a replacement or upgrade.
2. Match Your Unit to the Size of the Space
Not all air conditioners are built the same ,and choosing the right one depends on your room size, insulation, ceiling height, and heat load. Units that are too small will struggle to cool the space, while oversized units may short-cycle and waste energy.
Your air conditioner’s cooling power is measured in BTUs (British Thermal Units).
Other factors like direct sunlight, kitchens, or multiple occupants can increase the demand, so it’s worth getting professional input before buying.
3. Clean the Condenser Unit Regularly
Your outdoor condenser unit is crucial to the cooling process, as it releases the heat collected from inside. If this unit becomes clogged with dirt, leaves, or debris, it won’t function properly, putting strain on the compressor and reducing efficiency.
Check the unit monthly during warmer seasons. Use a garden hose to rinse off dirt and keep the surrounding area clear gently. Always turn off the power supply before cleaning. If in doubt, speak to us about our maintenance plans for homes and offices.
4. Replace or Clean Your Air Filters
Air filters trap dust, pollen, and other particles, keeping your air clean and your system running efficiently. Blocked filters restrict airflow, causing higher energy use and possible freezing of the evaporator coil.
Residential systems should have filters changed every 1–3 months. For businesses or homes with pets or allergy sufferers, change monthly. Not sure which filter you need? Contact your installer or our team.
5. Use Natural Cooling When Possible
In the UK, evening and early morning temperatures tend to drop. Rather than relying entirely on air conditioning, take advantage of natural ventilation when possible.
Open windows overnight, use cross-ventilation, and only switch to AC during peak heat. This approach saves energy and helps extend your system’s lifespan.
6. Use Blinds and Curtains to Reduce Heat Gain
A large proportion of indoor heat gain comes from direct sunlight. While daylight is excellent, it can quickly overheat rooms, causing your AC to work harder.
Use blackout blinds or thermal curtains during peak sun hours, particularly in offices or conservatories. Solar-reflective film can also help in commercial environments. This passive heat control strategy supports both comfort and energy efficiency.
7. Book Regular Air Conditioning Servicing
Just like your car, air conditioning systems need regular servicing to stay in peak condition. Preventive maintenance identifies small issues early and ensures your unit is working efficiently.
Benefits include improved cooling, reduced energy use, fewer breakdowns, and a longer system lifespan. Our certified engineers deliver expert routine servicing and maintenance across Bristol, Weston-super-Mare, and nearby locations.
FAQs: Making the Most of Your Air Conditioner
Is it bad to leave my air conditioner on all day? Not necessarily. Modern inverter systems are efficient and designed for extended use. For long absences, use eco mode or switch off.
How can I cool a room faster? Keep windows and doors closed while using the AC. Assist circulation with fans and keep vents unblocked.
Can I reduce humidity with my air conditioner? Yes — most systems naturally dehumidify. Some units have a dedicated setting, which is useful for the UK’s often damp climate.
