To protect business-critical equipment from data storage problems or system crashes, it is essential to ensure that the temperature in server rooms or data centres stays within certain limits. With many housing large amounts of equipment, the heat generated can potentially cause computers and networking equipment to fail as they are designed to work within a fairly narrow temperature range.     What temperature is right? Air conditioning should be considered crucial for any server room.   Technology experts recommend a server room temperature of between 18ºC to 27ºC and not less than 10°C or above 28°C.   Relative humidity should be between 45-50% to stop damaging static electricity building up.   Even a few degrees too hot can blow a server chip or cause permanent damage to hard drives.   The cost of a serious server failure can be considerable – not only the cost of replacement, but lost online business, lost customer details, wasted staff t...

Companies who service air conditioning units containing F Gas (fluorinated greenhouse gas) must, under a 2014 EU regulation, be certified to handle the F Gases. London Cool is registered with REFCOM (Register of Companies Competent to Manage Refrigerants), to show that we are certified to service stationary air conditioning and heat pump systems containing F Gas.   Servicing includes installing, repairing, maintaining, leak testing, commissioning and decommissioning.   Our engineers also have to be qualified as individuals if they handle F Gas. REFCOM has been appointed by the Secretary of State for Environment, Food and Rural Affairs (DEFRA) to operate as a certification body under the EU fluorinated greenhouse gas (F gas) regulation. In addition, all our air conditioning units containing F Gas must be labelled as part of the written procedures for handling F Gases and the equipment used.   We have developed a comprehensive set of labels to ensure we a...

Regular air conditioner servicing has many benefits Increased efficiency of operation Reduced chance of a costly, major breakdown at the worst time Longer lifespan of the unit Increased comfort Lower operating costs Improved air quality Priority call-out Adherence to manufacturer’s extended parts warranty Energy Efficiency Regular air conditioner servicing can improve your air conditioner's efficiency. A clogged air filter in your air conditioning system can affect its efficiency as it will obstruct the air flow and increase the energy consumption.   A clean air filter in your room air conditioner, whether it is a ceiling recessed cassette system, or a ceiling suspended system, saves 15 percent energy compared with a dirty one.   Dirty condenser coils will make the air compressor run harder which increases the energy consumption and your electricity bill.   Lower Repair Costs If regular maintenance is not carried out, your air conditioner co...
