1. Can low refrigerant levels cause my ac system to freeze? R-22 or 407c is designed to operate with suction pressures of 68.8 PSIG. If your HVAC equipment uses R-22, freezing will occur when the pressure drops to a low 57.6 PSIG. 2. What is causing my HVAC unit to get frozen? The easiest thing a Houston Homeowner can do before they call in for an emergency ac repair is checking your air filter.
If your air cleaner is clogged, it will block the airflow traveling across your HVAC cooling coils. Your filters protect your air condition from getting dirty. Not changing your purifier will cause your air conditioner to trap filth. Cleaning a dirty HVAC unit can be expensive & difficult to perform.
