Honda Ridgeline A/C blowing hot air intermittently on Honda Ridgeline

Some Honda Ridgeline owners report experiencing intermittent hot air from the air conditioning system due to various issues. One common cause is low or overcharged refrigerant, which can significantly affect the system's cooling capacity. Additionally, a malfunctioning compressor may lead to inconsistent cooling performance, while dirty condenser or evaporator coils can hinder the heat exchange process. Some owners have also reported problems with a faulty blend door actuator, which impacts air flow and temperature control. A defective evaporator temperature sensor can disrupt the system's ability to regulate temperature effectively, and a bad AC pressure sensor may cause irregular operation of the AC system. Less frequently, clogged expansion valves or orifice tubes, as well as blower motor issues, can also contribute to the problem. It is advisable for owners experiencing these issues to consult a professional mechanic for proper diagnosis and maintenance to ensure effective resolution.
