Air Conditioning

Regional leadership academy installs multi-unit air conditioning solution ahead of the summer

Because demand for air conditioning tends to be much higher in the summer, you’re better off booking an installation or maintenance service during periods in which cooling is less likely to required.

Choosing to upgrade your system during the winter eliminates the risk of impulse purchases and inadvertently selecting equipment that may not be right for your business or application.

It’s quite common for customers to contact us in January or February, with this approach ensuring that they are well prepared long before summer arrives. read more

Is your air conditioning system ready for operation?

With summer fast approaching, now is the time to ensure your air conditioning is fully prepared for the changing seasons. If you only need your air conditioning for summer cooling then it has probably not been used for several months. During this period of inactivity condensation and dust may have accumulated on fans, filters and heat exchanger coils. This can often become a breeding ground for bacteria which creates sludge and unpleasant odours.

If you also use your air conditioning to provide winter heating, it has probably collected lots of dirt and grime during that period. The colder conditions, even in relatively mild winters, encourage us to keep windows and other ventilation tightly closed. This reduces the amount of fresh air entering your building, leading to higher concentrations of dust and other airborne pollutants. Air conditioning works by recirculating air within the internal space, progressively cooling or heating it in accordance with user-controlled settings. Therefore, any fine particles being carried by the air will naturally end up in the filters, fans and fins of your air conditioning. read more

Is Planning Permission Required for New Air Conditioning?

The UK Planning Permission System operates to ensure that building plans contribute to the delivery of sustainable development so that new homes, businesses, shops, offices and public buildings are built in such a way as to protect and improve the environment.

Typically, planning permission applications from businesses relate to the building of new premises, alterations or extensions to existing premises, or the change of use of premises. To extend shops or offices you will always need planning permission. If you are altering or extending a listed building or a building in a conservation area you may also require conservation area and listed building consent before you proceed. read more

Heat pumps play vital role in emissions reduction targets

In a new report suggesting the UK will fail to meet its carbon emissions target, the Government Committee on Climate Change criticised inadequate investment in heat pumps, described as an important option for meeting carbon budgets.

Heat Pump Technology makes great sense

Heat Pump Technology makes great sense

According to the Committee on Climate Change, the UK is not on track to meet carbon budgets and suggests it will be necessary for Government to develop and implement further policy measures over the next two years to meet its commitments. Calling on the government to extend the Renewable Heat Incentive to the residential sector and ensure funding beyond 2015, it suggests allowing the Green Deal finance scheme to cover up-front costs of purchasing heat pumps. Current incentives are described as weak. read more

Air Conditioning Is Not To Be Sneezed At!

This year’s long cool spring, followed by a hot summer period has resulted in a particularly miserable time for hay fever sufferers as airborne pollen concentrations have hit unusually high levels.

Many of us will simply put up with the discomfort, whilst others will resort to antihistamine sprays and tablets. But there is another option. In this extreme hay fever season, many people are discovering the air purification benefits provided by air conditioning.

As Martin Willis, National Sales Manager of Andrews Air Conditioning Services, explains, ‘‘Modern air conditioning, in addition to delivering a steady stream of refreshing, cool air, is also fitted with high efficiency particulate air (HEPA) filtration systems. Capable of removing 99.97% of particles down to 0.3 micrometres in diameter, this technology purifies the indoor environment by removing a vast range of pollen, dust, mould spores and other pollutants. The advantages provided by air conditioning of effective summer comfort cooling and highly energy-efficient winter heating are well established, but they’re not the whole story.’’
So, to discover more about the environmental benefits of air conditioning, call Andrews Air Conditioning on 0800 731 8833. It’s not to be sneezed at! read more

Taking the Con Out of Air Conditioning

The issue of inferior products being passed off as quality brands is worryingly common in consumer market sectors. However, on the basis of recent evidence, it is now becoming a problem for buyers of air conditioning systems too.

Even Up Close, sometimes it's difficult to distinguish fake from genuine equipment

Even ‘Up Close’, sometimes it’s difficult to distinguish fake from genuine equipment

Most major air conditioning brands have experienced the issue and recently Toshiba, one of the world’s largest manufacturers of quality air conditioning, warned of its increasing prevalence. Toshiba first identified the issue around three years ago following an unusually large number of calls from users whose equipment had failed or was not performing as expected. read more

Why Does Air Conditioning Sometimes Smell?

During normal operation, air conditioning units tend to accumulate a wide variety of dirt, fibres, dust & pollen. If the unit is not properly and regularly maintained, this accumulation will combine with moisture in the environment, providing the perfect home for bacteria and mould. These organisms can emit nasty odours, spoiling the pleasant indoor environment the air conditioning is intended to create.

Regular Maintenance, Service & Repair Makes Good Business Sense
Saving Money and Energy and Preventing Disruption

Avoid air conditioning smells with the following tips :

• The air filters in both the indoor and outdoor units must be kept clean and clear of debris. If filters become blocked, the equipment will not only deliver reduced performance and consume more energy than necessary, it is much more likely to emit unpleasant odours. Inspect air filters regularly, particularly if the system operates in damp or dusty conditions.
• Ensure the condensate water drains and collection trays are not blocked and any condensate drain pumps and float switches are working properly. Drain lines on infrequently used systems, or those which are not flushed through frequently, can block leaving behind stagnant water.
• Clean heat exchanger coils and fins regularly. Dirt and grime may accumulate on the coils of the air conditioner which will also harbour odour-producing bacteria.
• Most important of all, have air conditioning professionally serviced on a regular basis to maintain performance, reliability and energy efficiency (generally at least twice per year). A Planned Maintenance Programme gives peace of mind and avoids the hassle of remembering to maintain and service equipment properly. read more

Daikin Announce Introduction of environment friendly ‘mildly flammable’ Refrigerant

As worldwide regulations curb the use of environmentally damaging chemicals, the air conditioning industry continues to innovate in the field of refrigerants. One example is the refrigerant Difluoromethane, also known as R32.

Replacement of Refrigerant should always be undertaken by a Specialist Contractor

Leading air conditioning manufacturer Daikin has announced that it intends to introduce R32 refrigerant in new air conditioning units manufactured for the Japanese market, with a planned roll-out into other regions, including Europe.

R32 is a single-component refrigerant, and although it is listed as “mildly flammable”, it has zero Ozone-depleting potential (ODP) and a much lower global warming potential (GWP) than R410A, one of the most commonly used air conditioning refrigerants throughout Europe and North America. R410A’s GWP is at 2088, whilst R32’s is significantly lower at 675. read more

Andrews Sykes Air Conditioning Services – Good Practice Notes: Legionnaires’ Disease

One year on from  outbreaks in Edinburgh and Stoke-On-Trent, Legionnaires’ disease, whilst increasingly less common, remains a potential issue for building owners, facilities managers and occupiers – especially in commercial and public buildings

Legionellosis is an infection caused by a bacterium named Legionella Pneumophila. Legionella are natural inhabitants of water and can be detected in rivers, lakes and streams.

Legionella

Patients with Legionnaires disease usually have fever, chills and a cough. Some patients have muscle aches, headache, tiredness and loss of appetite. Chest x-rays will often look like pneumonia, even to the trained eye, therefore it is difficult to distinguish Legionnaires disease from other types of pneumonia by symptoms alone. read more
