Carrier air conditioning unit not cooling. Condensing unit not turning on at all. If it is not possible to clean the air filter replace it. Air conditioning systems are more than just the condenser unit the ac unit or heat pump sitting outside your home. To remove debris from the air filter try cleaning the filter.

If the switch was accidentally set to fan however the unit will blow air through the duct system but no cooling will take place. Porator coils will frost over. Then yank the disconnect block photo 1 and clean the condenser coils photo 2. This greatly reduces the cooling capacity of the air conditioner.

The first areas that should be checked and cleared can be completed easily and quickly. If your air conditioner will turn on and your thermostat is set properly but your system is not cooling you may have a dirty or blocked air condenser. As was the case with evaporator coil issues a condensing unit might have an excessively dirty coil or refrigerant leakage. Check the air filter and change it if it looks like the filter on the right.

If your carrier air conditioning unit won t turn on there likely is an issue with its power source. These are fixes which should be accessible to any home owner. The air conditioner s inside unit called an evaporator absorbs heat from your air and then transfers that heat to the outside unit called the condenser. Check and reset the switch to automatic if necessary.

Additional issues with the outdoor condensing unit might include a faulty compressor a failing condenser fan motor or a faulty run capacitor. As it reduces the temperature your air conditioning system also provides another important comfort benefit pulling humidity from the air in your home. Your first step is to check the outside unit. Typical split system air conditioners have a lot of moving parts including an indoor air handler unit furnace or fan coil an evaporator coil air filter thermostat and copper tubing refrigerant lines that connect the.

Next turn off the power switch right at the furnace or air handler. Make sure the main power. If the air filter is clogged air cannot flow properly through the air conditioner. Check the outdoor cooling or condensing unit to see if it s running.

When you have a running compressor but your air conditioning unit is not producing cool air there are potentially a number of things that could be causing this problem.
