Match energy efficiency with complete flexibility of design and control

Modern Air Conditioning

Innovative and pioneering

Today’s commercial buildings are increasingly air tight and filled with heat generating office equipment and lighting, which presents a problem for anyone trying to maintain a stable and comfortable internal environment. With buildings accounting for around half of all UK greenhouse emissions, legislation is demanding higher standards of air quality and increased energy efficiency.

To reduce the impact of the built environment the challenge is to find cooling, heating and ventilation solutions that match energy efficiency with complete flexibility of design and control.

Innovative and pioneering air conditioning systems offer more than double the efficiency levels of 10-15 year old systems and can also be far more efficient than traditional methods of cooling and heating buildings, resulting in reduced running costs and lower carbon emissions.

Today’s systems can simultaneously heat and cool different spaces to balance energy use across a building.

AES are business solution partners with Mitsubishi. Mitsubishi is synonymous with excellence, and we pride ourselves in working alongside a company with such high standards and values.

R22 Refrigerant Legislation

Review, Replace or Recycle

R22 refrigerant is now banned

R22 refrigerant is now a banned substance.  Until 1 January 2015, it was used to complete most repairs and servicing of the majority air conditioning systems.

To comply companies are being encouraged to adopt new, low carbon technologies to improve efficiency.  The need to reduce CO2 emissions is further driving the demand for improved energy efficiency in every commercial building, whatever the application.

It should also be remembered that a more energy efficient system will enable building owners to achieve improved energy ratings under the Energy Performance of Building Directive.

Benefit from the ECA Scheme

You could make considerable savings on your running costs by simply putting an action plan in place. The government have put in place the Enhanced Capital Allowance (ECA) scheme which allows any company replacing an existing air conditioning system with a more energy efficient installation to offset the entire cost of the project against its taxable profits in the year the new system is installed.

If you are a building owner or occupier who is concerned about meeting your responsibilities, please do not hesitate in contacting AES for further information. Preparation and planning is key so be pro-active and make savings now.


Air Conditioning Servicing

A cost effective way to ensure smooth, reliable and energy efficient operation

Pre-Planned Maintenance

As with most electronic equipment it is recommended servicing is carried out regularly in order to ensure the system maintains is its optimal running efficiency in terms of reliability and operation.

In a productive office, it is understandable that the servicing of your air conditioning system does not always take priority. We all have busy working agendas. We recommend however, that taking the decision to act sooner can save you both hundreds of pounds in downtime and call out fees.

Our bespoke pre-planned preventative maintenance visits which are available on a yearly basis would substantially help reduce the chance of a breakdown occurring and maintain your system manufacturer’s warranty*.

You wouldn’t run your car without a service or an oil change and nor should you with your air conditioning.

*Assuming your system is within the manufacturer’s warranty period.

7 Year Comprehensive Insurance

Abel Environmental is proud to be affiliated with Mitsubishi Electric as a Business Solution Partner. This qualification status enables us to offer up to a 7 year fully comprehensive parts and labour warranty on Mitsubishi Electric air conditioning products we install and subsequently maintain.

Common Air Conditioning Problems

The main symptons

Many of the day-to-day air conditioning problems we encounter are caused by a lack of regular maintenance. We have listed below what we believe to be some of the main symptoms.

If you experience any of these issues please do not hesitate in contacting us to arrange an inspection, repair or service.

The two most common causes of your air conditioning system leaking is blocked drains or failed condensing pumps. Our expertly trained engineers will be able to quickly diagnose the cause of your issue and generally fix it in a very short period of time. We generally carry stock of the most common pumps in the market thus reducing your downtime.

Request Maintenance

Air conditioning system under performance is usually associated with dirty coils on indoor and outdoor units or a lack of refrigerant. Having a maintenance contract in place can significantly reduce call outs associated with this type of air conditioning problem as filters will be cleaned and in certain circumstances a refrigerant leak check is also carried out as part of our bespoke maintenance packages designed to prolong the life of your equipment.

Request Maintenance

As above the two most likely causes of condenser coils freezing is down to dirty coils or lack of refrigerant. As part of our maintenance package we will clean the outdoor condensing coil with industry standard condenser cleaner to ensure your system runs at optimum efficiency throughout the year.

Request Maintenance

If your AC unit is emitting unpleasant odours this is usually down to a lack of maintenance and or untreated / infrequently cleaned coils. In some circumstances this can also be due to a lack of ventilation within the room. It is important to remember that cassette and wall mounted air conditioning units only warm or cool the existing air and do not provide ventilation, so a lack of air changes in a room could contribute to bad odours.

Request Maintenance

Reduced airflow can be associated with something as simple as incorrect controls, louver failure or faulty fan motors. Its important to check that your controller is in the correct mode and the louver on the unit has opened the airways for the cool or warm air to escape. Our qualified engineers will be able to check the operation of the system and if necessary electrically test the function of the air conditioning unit.

Request Maintenance

The most common cause for rising energy bills is incorrectly set controls where the settings are set too high or two low. It is a common misconception that setting the controller down to 16 degrees will decrease the amount of time it takes to cool the room. Our air conditioning experts can discuss with you the most efficient way to control your air conditioning system. As part of our installation service we always ensure we provide a detailed handover to our clients to ensure they get the most out of their energy efficient air conditioning products.
