10 Energy Efficient AC Tips to Lower Your Bills and Stay Cool in London

Introduction

Running your air conditioner in London’s warmer months doesn’t have to mean sky-high electricity bills. With energy prices climbing and environmental concerns growing, energy-efficient AC use has never been more important. The good news? A few simple adjustments can drastically improve your cooling performance while cutting costs.

Here are 10 practical energy efficient AC tips to keep your home or business cool without wasting energy—or money.

Tip 1: Choose the Right-Sized AC Unit

Size matters when it comes to efficiency.

• Oversized units cool too quickly, cycle on and off often, and waste energy.
• Undersized units run constantly, struggling to maintain the temperature.

A professional assessment from MK Air Conditioning ensures your system is perfectly matched to your space.

Tip 2: Schedule Regular Maintenance

A well-maintained system runs smoother and uses less energy.

• Annual or bi-annual servicing can improve efficiency by up to 15%.
• Our £49 AC Health Check spots inefficiencies before they cost you.

Tip 3: Clean or Replace Filters Regularly

Dirty filters restrict airflow, forcing your AC to work harder.

• Check filters every 1–3 months.
• Replace or clean them as recommended by the manufacturer.

Tip 4: Keep Outdoor Units Clear

Your outdoor condenser needs good airflow to operate efficiently.

• Remove leaves, dirt, and debris from around the unit.
• Keep at least 2 feet of clearance around it.

Tip 5: Use a Programmable Thermostat

Set it and forget it.

• Adjust temperatures for different times of day.
• Avoid cooling empty rooms unnecessarily.
• Smart thermostats can reduce energy use by 10–15%.

Tip 6: Seal Your Home Against Air Leaks

Cool air escaping = money wasted.

• Seal gaps around windows and doors.
• Check ductwork for leaks and have them repaired.

Tip 7: Use Fans to Support Cooling

Ceiling and portable fans can make you feel cooler without lowering the thermostat.

• Fans use far less electricity than air conditioners.
• They help circulate cool air more evenly.

Tip 8: Close Curtains and Blinds on Hot Days

Direct sunlight can heat up a room quickly.

• Use blackout curtains during peak sunlight hours.
• This reduces the workload on your AC.

Tip 9: Upgrade to an Energy-Efficient AC Model

If your system is more than 10–12 years old, you could save up to 40% on cooling costs with a modern, high-SEER model.

• MK Air Conditioning installs energy-efficient AC systems tailored to London properties.

Tip 10: Use AC Economically

Small changes in behaviour make a big difference:

• Set thermostat to 24–25°C instead of 20°C.
• Turn AC off when leaving for extended periods.
• Use “Eco” or “Energy Saver” modes.
