How Can You Optimise HVAC Systems for Greater Efficiency?
Does your business have a combined HVAC system with heating, ventilation, and air conditioning? If so, optimising its energy efficiency is essential. HVAC systems play a crucial role in ensuring year-round comfort and indoor air quality. Still, they also use a large amount of energy. The Energy Saving Trust reports that space heating accounts for 49% of energy use in a non-domestic building.
An inefficient HVAC system can lead to:
- Rising energy bills
- Increased maintenance costs
- Discomfort for staff or customers
Optimising your HVAC system saves energy, reduces costs, and helps achieve sustainability goals. It also boosts comfort. This guide provides easy steps to boost your system’s performance and keep it effective over time.

How to Maximise Efficiency in Your Combined HVAC System
1. Schedule Regular Professional Maintenance
Regular maintenance is the foundation of an efficient HVAC system. Scheduling regular maintenance keeps your system efficient, helps avoid costly breakdowns, and lowers energy use.
Key tasks during maintenance include:
- Checking air filters: Clean filters ensure smooth airflow and optimal system performance.
- Cleaning coils: Prevents buildup that can reduce heat transfer and efficiency.
- Inspecting fan belts: Helps prevent unnecessary strain on your system.
A properly maintained HVAC system not only saves energy but also lasts longer, which can help your business save money. Dirty filters, for example, can block airflow, forcing the system to work harder. This leads to higher energy consumption and increased utility bills. Regular maintenance helps prevent sudden breakdowns. So you can keep your business operating smoothly and safe from any expensive interruptions.
The UK Government’s Energy Efficiency Advice emphasises the importance of regular maintenance checks. These checks are crucial for maintaining system compliance with energy efficiency regulations.
2. Upgrade to Smart Controls
Upgrading to smart thermostats and automated controls is an excellent way to enhance HVAC efficiency. These systems adjust the temperature based on the presence of people in the room, saving energy when spaces are not in use. It also means your business only heats or cools spaces when necessary. By doing this, you reduce energy waste and save on costs.
Smart controls enable businesses, including hotels, care homes, and offices, to manage fluctuating foot traffic effectively. These places often have different occupancy patterns during the day. These systems adjust to changes, ensuring comfort while reducing energy use. According to the Carbon Trust, businesses that install energy-efficient smart thermostats can cut fuel consumption by 8%.
3. Check & Replace Filters Regularly
Regularly replacing or cleaning your HVAC filters is one of the most cost-effective ways to improve efficiency. Clogged filters block airflow, forcing the system to work harder to maintain the desired temperature. This leads to increased energy consumption and higher utility costs.
To keep your system running efficiently:
- Check filters monthly: Inspect filters regularly to spot dirt or debris early.
- Replace filters every three months: For optimal performance, replace filters every 3 months.
- Increase replacements: Filters in schools, hotels, and factories may need to be changed more often. This helps maintain high air quality and efficiency.
Clean filters allow the system to operate smoothly, improving airflow and reducing strain. This saves energy and helps create a healthier indoor environment, reducing the risk of health issues associated with poor air quality.
4. Seal & Insulate Ductwork
Gaps in ducts cause heated or cooled air to escape, forcing the system to work harder to maintain the desired temperature. This leads to higher energy consumption and increased wear on equipment.
Sealing and insulating your ductwork helps air flow where it needs to go. This reduces strain on your HVAC system and enhances comfort. Sealing ducts can save businesses in large commercial spaces or multi-story buildings a significant amount of money over time. Investing in professional duct sealing stops energy waste. It also boosts HVAC efficiency and makes buildings more comfortable.
5. Monitor Energy Use
To optimise HVAC system efficiency, it’s essential to track your system’s energy consumption. Installing smart meters or a Building Management System (BMS) enables you to monitor energy use in real-time. This enables you to spot inefficiencies or energy spikes early. So you’re in a better position for quick corrective action before unnecessary waste occurs.
By using real-time data, you can ensure energy is used only when needed, optimising your system’s performance. A BMS offers detailed reports on energy consumption. This information helps you decide how to operate and maintain your HVAC system effectively. This ongoing monitoring ensures your system stays efficient, saving energy and reducing costs in the long run.
6. Consider System Upgrades or Retrofits
If your HVAC system is old or inefficient, upgrading to a new, energy-efficient model can save you a lot of money in the long run. Older systems consume more energy, break down frequently, and are less eco-friendly compared to newer, high-efficiency models. Upgrading your system reduces energy consumption, improves performance, and helps meet sustainability goals.
Upgrading to high-efficiency heat pumps or variable-speed fans can:
- Reduce energy costs
- Lower your carbon footprint
- Aid your environmental targets
UK businesses can benefit from incentives like the (now defunct) Enhanced Capital Allowance (ECA). When it was live, this scheme offered tax relief for energy-efficient systems.
