Air conditioning systems have become an essential part of our lives, providing comfort and convenience in hot and cold weather conditions. However, when an air conditioner fails to heat up, it can be frustrating and uncomfortable, leaving you shivering in the cold. If your air conditioner is failing to heat up, there could be several underlying issues. Fortunately, these can usually be fixed or avoided with ease.
The primary reasons why your reverse cycle split or ducted air conditioner isn’t heating include:
- Clogged air filters and coils
- Incorrect settings
- Defrost cycle malfunction
- Ice build up
- Circuit breaker or fuse problems
Circuit Breaker & Fuse Problems
Circuit breakers and fuses can be broken or defective, affecting the aircon’s heating performance. Switching them back to the on position after they’ve been tripped or undergoing an air conditioner repair can help, but if this doesn’t work, the system’s overall performance will be impacted negatively.
Clogged Air Filters & Coils
Clogged air filters and coils can also lead to various issues, including an inability to heat. The filters should be replaced at least once a year to ensure the air flowing through the system is filtered, and the evaporator and condenser coils should be cleaned at least once a year.
Incorrect Settings
Incorrect temperature and aircon settings can be another reason why the air conditioner isn’t heating. For example, the system may be blowing out cool air due to the aircon being set to the ‘cooling’ mode. It’s important to check that the system is running at the desired temperature and in the correct mode.
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 prevent freezing and ice build up during winter, but there may be an error with the settings of the system that stops it from switching back. A qualified air conditioner technician may be required to resolve the issue.
Ice Build Up
Ice build up inside the unit is a common issue in the winter months when the outdoor system becomes too cold. The outdoor unit should warm itself up to help conserve energy, however, it can often lack the necessary ventilation or be too old and not serviced, resulting in ice build up. This can expand and damage parts of the aircon, causing motors to malfunction and reducing the ability to heat.
