HVAC systems can freeze up due to restricted airflow, low refrigerant levels, or a malfunctioning thermostat. When airflow is restricted, the system may not be able to properly circulate air, leading to ice buildup. Low refrigerant levels can also cause the system to freeze as it affects the system's ability to absorb heat. A malfunctioning thermostat can cause the system to run continuously, leading to excessive cooling and potential freezing.
It's unusual for PTAC HVAC units to freeze up in AC mode however it can occur typically due simply due to not enough cool air circulation through the coils within the unit. Hope this helps! Valley Of The Sun. http://ptacunits.com/about-us
An air conditioner can freeze up due to low refrigerant levels, restricted airflow, or a malfunctioning thermostat.
A heat pump can freeze up due to low refrigerant levels, restricted airflow, or extremely cold temperatures.
Normally "HVAC" refers to "Heating, Ventilation and Air Conditioning". An HVAC engineer designs heating and cooling systems for homes and commercial buildings. He or she uses knowledge of mechanical engineering and refrigeration to design HVAC systems - drawing up blueprints for HVAC installers and general contractors. The HVAC engineer is responsible to design systems that keep building occupants comfortable in all types of climates and seasons. He or she also makes sure the building will be well-ventilated to protect the health of occupants. The HVAC engineer must also work with whoever is designing the building (if it is a new building) or the building manager (if it is an existing building) to design the system to maximize energy efficiency and minimize the operating and maintenance costs.

If you mean freeze as in ice up it is probably low on freon.
HVAC is short for heating, ventilation and air conditioning. So an HVAC job would be any job to help with climate control, such as an AC repairman.If you have any other questions, look up Reynolds Air & Heat and check out our blog posts.
Central air conditioning units can freeze up due to restricted airflow, low refrigerant levels, or issues with the unit's components such as the coils or filters.
Your AC may freeze up due to low refrigerant levels, restricted airflow, or a malfunctioning thermostat. To prevent it from happening in the future, make sure to regularly change the air filters, keep the coils clean, and have your system inspected and maintained by a professional HVAC technician.
Low airflow, low refrigerant or restriction
There are typically three main categories of on-the-job events in HVAC: installation, maintenance, and repair. Installation involves setting up new HVAC systems, maintenance includes routine checks and servicing to ensure efficient operation, and repair addresses issues that arise during the system's lifecycle. Each category requires specific skills and knowledge to ensure safe and effective HVAC operation.
The suction point of an air conditioning compressor can freeze up due to restricted airflow, low refrigerant levels, or an issue with the evaporator coil. This can cause the refrigerant to expand rapidly, leading to freezing at the suction point. It's best to have a professional HVAC technician diagnose and resolve the issue to prevent further damage to the system.
