FAQ

• What maintenance should I do on my air conditioner?

  The most important maintenance you can do is to change your filters regularly. Ground mounted outdoor units need to be kept clear of debris, clutter; weeds or landscaping that can grow too close and reduce the airflow to the unit. Also, keep pets away from the unit because pet urine can cause expensive damage. Use caution with a weed trimmer around the unit to prevent damaging control wiring. Any additional maintenance should only be performed by qualified personnel.
  

• What size is my filter and how often should I replace?

  There's no one-size-fits-all answer. The frequency of filter changes is driven by how much your heating and air conditioning system operates, which is also driven by your individual climate. Start by checking the system's filters at least once a month. Hold the used filter up to the light and compare it to a clean "spare". When light is obscured by captured dust and dirt particles, the old filter should be changed. Keep a record for one year and then replace the filter on that basis. At a minimum, it is always a good idea to change filters at the start of the heating and cooling seasons and then in between according to your need. Also, it is a good idea to have your heating and air system checked at the beginning of heating and cooling season to insure proper operation.
  

• What is meant by a 'ton' of refrigeration?

  Confusingly, the unit has little to do with weight, as used in everyday language. One ton of refrigeration is the term used to refer to 12,000 B.T.U.s/hour (British Thermal Units/Hour) of cooling effect. Thus, a condensing unit with a cooling capacity of 60,000 B.T.U.s/hour is said to have a capacity of 5 tons.
  

• What temperature of the air should my AC produce?

  The temperature of the air that your system produces depends on the temperature of the air going in. The air produced should be 18 to 20 degrees lower than what enters the system. Thus, if the air entering the system is 70°, the air exiting should be about 50°-52°. This only works if the system has been on and running for at least 15 minutes. On a mild day, the air coming out could be 15°-17° cooler than what enters.
