High Head Pressure Causes and Solutions Dirty Coils. Dirty condenser coils are a primary culprit behind high head pressure in HVAC systems. Dirt acts as an insulator, trapping heat inside the unit. This hinders heat transfer, causing the system to work harder to cool the space. The result is increased pressure within the system. High head pressure for 410A is an indication of a system that has lost its ability to evaporate refrigerant correctly. This can be caused by many things including low charge, clogged air filters, restricted airflow, or dirty coils. High head pressure creates higher discharge temperatures and forces the compressor to work harder than necessary.
