Choosing heating, cooling and ventilation systems that are kinder to the planet is now a priority for many homes and businesses. We’re more aware than ever of how our energy use impacts the environment, and air conditioning has historically had a poor reputation when it comes to efficiency and refrigerants. The good news is that modern systems – when chosen, installed and used correctly – can be far more sustainable.
At Controlled Climate, we design and install energy-efficient air conditioning and heat pump systems across Bristol and the South West. Below, we share practical ways to make your air conditioner as environmentally friendly as possible.
1. Choose the Right Size and Type of System
One of the biggest factors in how much energy your air conditioner uses is whether it’s correctly sized for your space. An undersized unit has to work overtime to try to reach the set temperature, while an oversized unit will keep cycling on and off, wasting electricity and causing unnecessary wear on components.
If you’re unsure what capacity you need, our guide What size air con unit do I need? Explains BTUs, room measurements and other key considerations to help you choose an efficient system.
2. Use Smart, Fully Programmable Controls
Modern systems come with sophisticated controls that allow you to avoid running the unit unnecessarily. A fully programmable or smart thermostat lets you:
- Set comfortable temperatures for different times of day
- Create schedules for weekdays and weekends
- Ensure the system isn’t cooling or heating empty rooms
- Fine-tune settings remotely via an app (on compatible systems)
Using scheduling and zoning features properly can have a real impact on your overall energy consumption and running costs.
3. Consider High-Efficiency Heat Pumps and Systems
If you’re planning a new installation, it’s worth exploring technologies designed with efficiency in mind. Options include:
- Air source heat pumps that provide both heating and cooling with excellent seasonal efficiencies
- Advanced inverter-driven systems that precisely match output to demand
- Multi-room or zoned systems that only condition areas that are actually in use
Working with an experienced designer will help you choose the right setup for your building and usage patterns, reducing wasted energy.
4. Keep on Top of Servicing and Maintenance
Even the most efficient system will struggle to perform if it isn’t looked after. Dirty filters, blocked coils and low refrigerant levels all force your air conditioner to use more electricity to achieve the same result – and that means higher bills and a bigger carbon footprint.
We generally recommend an annual service for domestic units, and at least twice-yearly maintenance for heavily used commercial systems. Our dedicated air conditioning service and maintenance packages are designed to keep your system running efficiently for longer.
5. Use Your System in an Eco-Conscious Way
How you use your air conditioner day-to-day is just as important as the technology itself. Small changes can make a meaningful difference:
- Set realistic temperatures rather than the lowest possible setting
- Close doors and windows while the unit is operating
- Use blinds or curtains to reduce solar gain on very hot days
- Combine air conditioning with good insulation and draught-proofing
If you’re unsure whether air conditioning is right for your property or how it will affect energy use, a specialist survey can help you understand the likely running costs and efficiency.
6. Stay Up to Date with Regulations and Inspections
There are specific rules around the inspection and efficiency of certain commercial systems. Keeping on top of these not only helps you stay compliant but also encourages better performance and reduced environmental impact. Regular checks can highlight opportunities to upgrade older, less efficient equipment.
Work with an Expert, Eco-Focused Installer
Choosing an experienced, REFCOM-accredited installer is one of the easiest ways to ensure your system is specified and set up with efficiency in mind from day one. From single-room residential units to complex commercial installations, the right design will help you minimise energy use without sacrificing comfort.
If you’d like tailored advice or a detailed assessment of your property, you can request a free air conditioning survey, and we’ll recommend the most energy-efficient options for your space.
