Why Is My Air Con Cooling But Not Heating?
Your reverse cycle air conditioning may be cooling your home but your air conditioner heating function may not be working correctly. When the air conditioning unit cools but does not heat the home then there can be multiple errors with the system. Often these issues can be easily fixed or avoided and at times an Air Conditioning Repair service is needed. Logicool Air offers reliable repairs with reverse cycle air conditioners where we will resolve any air conditioner heating problems professionally and efficiently!
The main causes of air conditioner heating problems with reverse cycle systems are:
- Ice building up
- Clogged air conditioner filters and coils
- Circuit breaker and fuse malfunctions
- Incorrect settings
- Defrost Cycle
Why Does the Air Conditioner Cool But Not Heat?
A reverse cycle aircon offers both heating and cooling functions but at times the system might only produce cool air. The heat output may be minimal or none when the system has been set to heat mode. This issue of the system not heating can occur with all types of aircons, from split system air conditioners, ducted systems to portable air conditioners.
The main reasons why the reverse cycle split or ducted air conditioner not heating include the following:
Ice Build Up
Ice building up inside the unit occurs when the outdoor system becomes too cold when in winter months. As the indoor unit warms the air the outdoor unit remains cold to help with the heat energy efficiency. The outdoor unit will automatically warm itself up due to this but at times the system may not heat itself enough. This may be because of the outdoor system not having enough ventilation or it is old and has not been serviced.
Ice build up can expand and parts of the air conditioner can become damaged causing them the break. Motors can malfunction and the ability for the system to heat can be greatly impacted. e bits can also break and affect other areas of the aircon which can lead to other problems, such as refrigerant leaks.
Clogged Air Filters and Coils
A problem that can lead to many difficulties, including no heating, are clogged coils and filters. When these are blocked the compressor and other parts of the system can fail prematurely and stop the aircon heating. The filters of an air conditioner should be replaced at least once a year to ensure the air flowing through the system is filtered. The evaporator and condenser coils should also be cleaned at least once a year to prevent heating problems.
Circuit Breaker and Fuse Problems
When the circuit breaker and fuses of the aircon system have been broken or are defected then this can lead to poor heating performance. Switching them back to the on position after they have been tripped or undergoing an aircon repair for major issues may be needed. When these do not work then the overall system is negatively affected, including the ability for the aircon to reach the desired temperature.
Incorrect Temperature and Aircon Settings
At times the settings of the air conditioner may be in the wrong settings which may be why the air conditioner heating is affected. For example, the system may be blowing out cool air due to the aircon being set to the ‘cooling’ mode. Checking that the system is running at the desired temperature and in the correct mode is important. An Air Conditioning Service may be needed for a technician to look over the settings if they are more complicated to alter.
Defrost Cycle
The defrost cycle is when the indoor unit will blow out cool air so the outdoor unit can warm up. This is to ensure the system does not freeze and to reduce the chance of ice building up during winter. There could be an error with the settings of the system that causes the aircon to not switch back into the correct settings. This is when a fully qualified air conditioning technician is needed as they will be able to resolve the glitch.
Why Does My Daikin Unit Cool But Not Heat?
As with all air conditioning systems they can express the issue with only cooling and not heating. Daikin air conditioners may experience this issue of the unit not heating but only cooling. The best ways to resolve this air conditioner heating issue with Daikin systems are to:
- Wait 10 minutes as the defrost cycle might be occurring so the system remains warm and efficient
- Inspect to see if the power has gone out for the system, if the circuit breaker has tripped or if the system has been accidentally turned off
- Have a professional ac technician inspect the Daikin unit to ensure they can properly resolve the error
