Why is the air conditioner not blowing air when heating?

[OAshlyn]

There are many reasons why the air conditioner may not blow air when heating, such as a clogged filter, insufficient refrigerant, or unstable voltage. Different issues require different solutions. The specific troubleshooting steps are as follows: Wait for the outdoor unit to operate: When the air conditioner is heating, the indoor unit does not blow air immediately. It takes about 3-5 minutes for the outdoor unit to start working before air is blown out. Cleaning: If there is no air flow for a long time, it may be due to a clogged filter caused by accumulated dust. In this case, the filter of the indoor unit and the condenser of the outdoor unit need to be cleaned. Contact after-sales service: If the air conditioner still does not blow air, it may be due to insufficient refrigerant or the outdoor unit not working. You can contact the manufacturer's after-sales service for an on-site inspection. Circuit inspection: Unstable voltage may also cause the air conditioner not to blow air when heating. In this case, you need to contact the property management to inspect the home's electrical circuit.
