Air conditioning can be a problem for some people because of the condition the apparatus is in. Even for internal and portable units, the filters need to be checked. This should be done once a year if the system is a conventional unit. But you should check it every six months if it has a heat pump.
The other thing that should be done is to clean the drain of the indoor unit. This keeps bad odors away and prevents the drain from clogging.
The exterior component of the air conditioner, the compressor, needs to be cleaned with pressurized air or with a brush. The condenser should also be checked and cleaned at the end of every season, four times a year. An air conditioner should be seen by a technician at least once a year.
Problems with air conditioning can be expensive to fix, but frequent air conditioning problems are easy to identify. On occasion, the air conditioner does not blow cold air in. This can be caused by a dirty filter which can also block the condenser and make the AC unit and AC system air quality not work. It is a good idea to change the air filter once a month.
Another problem to look out for is the air conditioner freezing up on the external components. This might be because of restricted airflow, low levels of coolant in the unit, or low temperatures outside. A problem with the blower motor could be the cause of this, too.
Loss of refrigerant in the unit can make it work erratically.
A frequent problem is a leaky AC. Usually, you can expect leaks from an air conditioner on hot days when the unit is operating.
