Service maintenance contracts are not always considered at the time of installation or when a warranty period comes to an end. Once a new piece of air conditioning, heating and ventilation system or refrigeration system is installed it requires regular servicing to maintain optimum performance.. Dirt and neglect are the number one causes of heating and cooling system failures. Over 50% of emergency call outs to air conditioning, ventilation and heating systems could have been avoided if proactively serviced and maintained.
