Check your thermostat to make sure it’s set properly to heat or cool, and the setting is set higher or lower than the temperature it’s reading.

Check to make sure the circuit breakers are not tripped. Reset them by turning the breaker off then on (some older homes have fuses that might
need to be replaced if blown).

Check your filter or filters, if they get clogged this will make the evaporator ice up. If this happens the system will need to defrost, this can take a
few minutes to several hours (to help it along put the fan to the on position until the system is defrosted then return the fan to the auto position.

Replace your filter once a month or as stated on the filter (some may be good for 90 days some for 180 days). Dirty filters can lead to a dirty
evaporator coil that might need cleaning.

Check to make sure your thermostat has good batteries.

Make sure your system is not off due to the float switch (this is a switch that shuts the unit off because the main drain is stopped up). In horizontal
applications you will need to remove the water from the pan & clear the main drain. In vertical applications this switch is next to the main drain &
has two wires connected to it (clear the main drain & remove any water from the auxiliary drain line).

Make sure the outside unit is free of plants & bushes that might restrict the air flow. Also make sure it isn’t covered with dirt. If it is covered with dirt
shut off the power to the outside unit & flush the coil with clean water making sure not to bend or damage these coils.
