Is your air conditioner just not keeping the house as cool as it used to? When was the last time you changed your air filter? A dirty air filter can restrict air flow and cause a number of problems, one of them being the inability to cool your house properly. Check your filter regularly.
Another possible cause is low refrigerant levels. Units do require refrigerant top ups occasionally as there may be a slow leak in your system. This leak can be detected and repaired by a qualified technician.
