While Carrier prides itself on reliability and offers a warranty with its air conditioners, you may encounter problems that prevent the unit from properly working. You can save time by performing some troubleshooting steps, such as resolving power issues or cleaning filters. However, it's important to be able to identify issues that require a professional service call, such as the indoor unit fan emitting warm air or the system struggling to keep up, so your unit is repaired before serious damage occurs.
Power Up
If your Carrier air conditioning unit won’t turn on, there likely is an issue with its power source. Check the outdoor cooling or condensing unit to see if it’s running. Make sure the main power switch for the outdoor unit is in the "on" position; the switch usually is a few feet from the unit inside a box mounted to your home’s exterior. If the switch is in the "on" position but the outdoor unit isn’t operating, check your home’s circuit breaker or fuse box. Reset the circuit or replace a blown fuse as necessary.

Filter Out
Your Carrier air conditioning unit may fail to operate properly if its filter is dirty. Buildup on the filters blocks airflow and causes the air conditioner to shut down. Examine the filter to see if there is excess buildup that might be preventing it from properly cooling. If you use 1-inch-thick filters, they should be changed once a month. With 2-inch or other high-capacity pleated filters, you usually can change them every other month unless you notice they fill up quickly because of poor air conditions; eplace them monthly if necessary.
Clear the Air
Your air conditioner may fail to cool your home effectively if its return-air grilles are blocked. The return-air grilles are large and usually located on the wall or ceiling in a new home. If your home is older, your return-air grilles may be on the floor. Make sure the grilles aren’t blocked by furniture, vases, picture frames or other items that can impede airflow. Dust the grilles every other week so debris doesn’t collect along the openings and restrict the airflow.
Out of Service
If you’ve checked your Carrier air conditioning unit’s power, filters and return-air grilles and it still is not cooling your home properly, call a Carrier service technician for assistance. For example, if your air conditioner continually turns itself on and off or your home’s indoor humidity levels seem extremely high, arrange a service call. You should call your Carrier service provider if you can hear your indoor unit fan turning on but the air that it emits isn’t cool, or the fan regularly turns off and on.
