Your Honeywell AC won’t blow cold air because of one of these five issues:
Airflow issue – Either due to a dirty filter, dirty or frozen evaporator coils, blocked or leaky exhaust vent, or insufficient clearance around the unit.
Thermostat issue – It could be due to a wrong thermostat setting, failed thermostat powering, or thermostat wiring fault
Compressor issue – The compressor might be on a 5-minute delay start, lacking power, or just defective.
Furnace issue – The furnace might not work due to an unlatched door or power failure.
Refrigerant issue – Possibly a leakage.
Let’s now discuss these issues in detail:
5 Reasons Your Honeywell Air Conditioner Is Not Cooling
Discussed are the five likely issues to explain why your Honeywell air conditioner won’t cool and what to do about them:
1. There Might Be a Problem with The Airflow
Unless there is proper airflow, where hot air vents out or cold air circulation is unobstructed, your Honeywell air conditioner won’t cool. In that case, watch out for any of these issues:
Dirty air filter – Once the air filter accumulates dirt and clogs, the clog obstructs the airflow, which means your air conditioner cannot block cold air.
Dirty or frozen evaporator coils – The evaporator coils can also prevent your AC from blowing cold if they are either filthy or frozen.
Blocked or leaky exhaust vent – If the exhaust vent is blocked, it will prevent hot air from exiting the unit, and if it’s leaky, then hot air will leak and interfere with the room’s cool air.
Insufficient clearance – There should be sufficient clearance around the air conditioner to encourage good air circulation. However, if there are obstructions around the unit, the unit will fail to circulate cold air properly.
Fix
Clean the air filter and the evaporator coils if any of them is filthy. And for the latter, unplug the Ac to allow it to defrost naturally if the coils are frosty.
Straighten out the vent or clean it if it’s clogged to improve the emission of hot air, and if the duct is leaky, replace it. Meanwhile, ensure there is enough clearance around your Honeywell air conditioner.
2. The Thermostat Might Not Be Working
The thermostat plays a critical role in the running of your AC. If it doesn’t run for whatever reason, the AC won’t blow cold, and that brings us to these issues:
Wrong thermostat setting – The thermostat will only let the AC start cooling if it’s on Cool Mode. Its temperature setting should be lower than that of the room. Sometimes, it may take up to 5 minutes before the AC starts cooling.
Lack of power – If the thermostat is battery-powered, consider that the batteries might be dead. That’s often the case when you use them for over a year.
Wiring fault – You must correctly connect the YG wires to their respective terminals. If you still have doubts, consult your Honeywell AC manual, as any wrong configuration could prevent the AC from working.
Fix
Ensure you set the thermostat on ‘Cool’ Mode and wait for a few minutes to bypass the delay phase (about 5 minutes). If the thermostat has no power, replace its batteries, and in the meantime, check the YG connectors to ensure that the wiring is correct.
Consider using your Honeywell Ac manual to connect the thermostat wiring properly.
3. The Compressor Might Not Be Running
Your AC won’t do anything even cool if the compressor is not running and here are the things to check out:
Start Delay – The compressor typically takes up to 5 minutes before starting once you hit the power button. That doesn’t mean the compressor is bad, but it is intended to protect the Ac from temperature variations.
Lack of power – If your Honeywell air conditioner doesn’t turn on, perhaps due to lack of power, then the compressor won’t kick in, and as a result, the AC won’t cool the space.
Defective compressor – If you can’t hear the compressor kick in when you power the AC on and it has taken more than 5 minutes, the compressor could be dead.
Fix
Wait at least 5 minutes for the delay start time to end and then check the AC’s power. If the AC has power, consider replacing the compressor, as it is likely defective.
4. The Furnace Might Not Be Working
The furnace must work for the Honeywell air conditioner to cool your space. The AC will have difficulty keeping your room cool if it doesn’t. Here’s what might be wrong:
An unlatched door – The furnace won’t run if the furnace door is not closed firmly. So, you’ve to inspect it. And if the furnace doesn’t run, it’ll be hard for your AC to cool or heat your indoor space.
Failed power – If the furnace’s power button is off, the furnace won’t run; the same goes for the circuit breaker. If the breaker is off, the furnace won’t switch on.
Fix
Check the furnace door and securely latch it if that’s not the case. Then check the furnace power button and the circuit breaker to ensure they are both ON. If not, turn them ON.
5. Low Refrigerant
Lastly, if the refrigerant level is lower, most likely due to a leakage, what remains won’t be enough to absorb heat from the room. And as a result, the room will feel hotter despite the AC running.
As the unit runs, you can tell if your AC’s refrigerant leaks if there’s a hissing/bubbling sound.
Fix
If you notice a hissing or bubbling sound from your AC, the refrigerant is likely leaking. And if so, you should call an expert. Refrigerant leakages require expert skill to fix.
Honeywell Portable Air Conditioner Not Cooling
Consider these issues if your Honeywell portable AC won’t blow cold air:
The air filter could be filthy
The evaporator coils could either be frosty or dirty
Wrong setting (the thermostat is not on Cool Mode)
Fan problem – The fan is faulty or running on a low-speed setting
Inadequate clearance around the portable unit
Blocked exhaust vent, which won’t vent out hot air
Leaky refrigerant
Non-running compressor
Honeywell Central Air Conditioner Not Cooling
If your Honeywell Central AC won’t blow cold air, it’s most likely due to one of these reasons:
Poor airflow, which is associated with lack of clearance and the AC, dirty filter, frozen or filthy evaporator coils, or blocked exhaust vent
Wrong thermostat setting – Especially the thermostat not on Cool Mode
Non-working thermostat, either due to dead batteries or defectiveness
Non-working furnace either due to an unlatched door or failed power
Failing compressor
