Warm air coming from your vents can quickly become a serious comfort problem during a Panama City summer. While an incorrect thermostat setting or dirty filter may sometimes be responsible, an AC system that runs constantly without cooling can also have refrigerant, electrical, airflow, or mechanical problems. Continuing to operate a struggling system may increase energy use and place added strain on expensive components. <\/p>\n\n\n\n\n\n\n\n

Start With Simple Thermostat and Airflow Checks<\/strong><\/h3>\n\n\n\n

Before assuming the AC has suffered a major failure, confirm that the thermostat is set to \u201ccool\u201d and the selected temperature is lower than the current indoor temperature. The fan should generally be set to \u201cauto.\u201d When the fan is set to \u201con,\u201d it may circulate room-temperature air between cooling cycles, making the air from the vents feel warmer.<\/p>\n\n\n\n

Next, inspect the air filter. A clogged, bent, or heavily coated filter can restrict airflow through the system. Without enough airflow, the evaporator coil may become too cold and begin to freeze. This can weaken cooling performance and eventually stop conditioned air from reaching the rooms.<\/p>\n\n\n\n

Homeowners should also make sure supply vents and return grilles are open and clear of furniture, curtains, rugs, and storage items. If replacing the filter and clearing the vents does not improve cooling, our Peaden Pros can inspect the system for a deeper airflow problem.<\/p>\n\n\n\n

Refrigerant Leaks Can Cause Weak Cooling<\/strong><\/h3>\n\n\n\n

Refrigerant allows the AC system to absorb heat from inside the home and release it outdoors. When refrigerant escapes through a leak, the system may continue running while producing little or no cool air.<\/p>\n\n\n\n
