If you’re looking for a new air conditioning unit in Warwick or the wider Warwickshire area you may be wondering how much electricity they use and if it’s an affordable solution for your home or business. Let’s take a look.

The energy consumption of air conditioners depends on several factors, including the size and efficiency of the unit, the climate, the temperature settings, and usage patterns. While air conditioners can contribute to significant energy usage, especially during hot summer months, there are ways to minimise energy consumption and lower your electricity bills. Here’s what you need to know about the energy usage of air conditioners and how to make them more energy-efficient:

SEER Rating

The Seasonal Energy Efficiency Ratio (SEER) is a measure of an air conditioner’s energy efficiency, calculated by dividing the cooling output during a typical cooling season by the total electric energy input during the same period. The higher the SEER rating, the more energy-efficient the air conditioner is. When purchasing a new air conditioning unit, look for models with higher SEER ratings to maximise energy savings and reduce electricity consumption.

Proper Sizing and Installation

Proper sizing and installation are crucial for ensuring the energy efficiency of an air conditioning system. An oversized unit may cycle on and off frequently, leading to inefficient operation and higher energy consumption, while an undersized unit may struggle to cool the space adequately. Work with a qualified HVAC technician to size and install the air conditioning unit correctly, considering factors such as the size and layout of the space, insulation levels, and climate.

Regular Maintenance and Cleaning

Regular maintenance and cleaning are essential for keeping air conditioners operating efficiently and minimising energy consumption. Change or clean the air filters regularly to ensure proper airflow and reduce strain on the system. Keep the outdoor unit clear of debris, such as leaves, dirt, and vegetation, to maintain optimal airflow and heat exchange. Schedule annual maintenance inspections with a professional HVAC technician to identify and address any issues that may affect the efficiency of the system.

Programmable Thermostat

Installing a programmable thermostat allows you to set temperature schedules based on your daily routine and preferences, reducing energy consumption when the space is unoccupied or during nighttime hours. Program the thermostat to automatically adjust the temperature settings to save energy while maintaining comfort when you’re home. Consider upgrading to a smart thermostat for additional features, such as remote access and energy usage monitoring, to further optimise energy efficiency.

Energy-Saving Tips

In addition to using energy-efficient air conditioning equipment and maintaining proper installation and maintenance practices, there are several energy-saving tips you can implement to reduce the energy consumption of your air conditioner:

  • Close curtains or blinds during the hottest part of the day to block out sunlight and reduce heat gain.
  • Use ceiling fans in conjunction with air conditioning to help distribute cool air more evenly and reduce the workload on the air conditioner.
  • Seal gaps and cracks around windows and doors to prevent cool air from escaping and warm air from entering the space.


While air conditioners can use a significant amount of electricity, there are several ways to minimise energy consumption and lower your electricity bills. Choose energy-efficient air conditioning equipment with high SEER ratings, properly size and install the unit, schedule regular maintenance and cleaning, use a programmable thermostat, and implement energy-saving tips to maximise energy efficiency and reduce your environmental impact.
