If the condenser doesn’t turn on, then the air conditioner will not work.

This can occur for several different reasons.
This uneven cooling is generally the result of closed or clogged vents.
Check to double-check that the thermostat is set to the right temperature.
If it is too high, then the air conditioner will automatically turn off before properly cooling the home.
Alternately, the evaporator coils may be too dirty.
This can be resolved by cleaning the evaporator coils in most cases.
The issue could also be the result of faulty wiring, dirty condenser coils, or dirty evaporator coils.
Faulty Thermostat
If thethermostatisn’t working right, nothing else with the HVAC system will work right.
The thermostat is the brain of the entire system.
All thermostats need power.Thermostatscan be powered by batteries, by a low voltage wire, or by both.
If power is compromised, thethermostatwill not work.
Additionally, thermostats aren’t always well-placed in the home.
Yours may have been installed where sunlight hits it or next to a cool area with a draft.
If the air conditioner doesn’t seem to have power, check the breaker panel or fuse panel.
If this occurs, the system may have a dirty air filter.
Test the Thermostat
Another common cause of problems for your air conditioner is thethermostat.
Replace the battery or check the low voltage wire connection to restore power to the thermostat.
If the thermostat has power, then the issue may be because the temperature is set too high.
Lowering the temperature should activate the air conditioner.
If this occurs, the temperature reading on the thermostat may not accurately gauge the temperature throughout the home.
During this time, ice can build up on the air conditioner.
The fix for this is easier than most.
This will allow the ice to melt on its own, freeing the air conditioner.
Trimming down any bushes, trees, and other foliage should prevent the compressor from overheating or becoming obstructed.
However, even with clean vents the airflow can be restricted if the ducts are too dirty.
Inspect the air ducts for signs of significant dust, hair, dirt, and debris build-up.
Check your HVAC system to determine if the evaporator coils are accessible.
Turn off the air conditioner, then remove the tape and the screws holding the access plate in position.
Use a stiff-bristle brush and a mild detergent to clean the entire evaporator unit.
you’re able to use a small hand mirror to help see what you are doing.
Reinstall the access plate and tape the insulation back into position.
Clean the Compressor Coils
Dirty compressorcoilscan cause just as many issues as dirty evaporator coils.
Head outside to the compressor and inspect the coils for dirt, dust, and debris.
Use a mild detergent and a soft-bristle brush or microfiber cloth to clean the coils.
Examine the Coolant Lines
Most air conditioning system use a refrigerant known as Freon as a coolant.
If the coolant lines are damaged, then there could be a leak in the system.
Replace any damaged or worn insulation on the coolant lines and check for leaks.
If youspot any leaksor notice the coolant levels are too low, contact an air conditioner repair professional.
Do not attempt to patch the leak or charge the system’s coolant lines.
