There are several reasons why your AC may be blowing sizzling air.
The control unit is a enjoyable locale to start looking for the culprit.
It sounds too self-explanatory. This is a usual reason why your cooling system might be doing the opposite of what it should. Low refrigerant can cause your cooling system to only blow sizzling air. Do not attempt to repair this yourself. Coolants, also known as refrigerants, can be legitimately dangerous. To purchase and handle this substance, you must be a licensed HVAC specialist. Your HVAC system’s air filters may seem unimportant, but they are essential; HVAC filters remove dust, dander, and other airborne contaminants from the air reentering your home from the system! Over time, the debris that’s caught will clog up your air filters, when this happens, your cooling system will struggle to push air past the filter into the system. This strain can lessen air flow and even cause your plan to blow warm air instead of cool. Take a peek at your filters, and if they’re dirty, upgrade them to see if it makes a difference in airflow and temperature, then frozen evaporator coils can cause your plan to blow sizzling air as well. Some things which can be preventing airflow to the evaporator coil include jammed ductworks, a dirty coil, or low refrigerant. If you find your plan frozen over, turn off your cooling system and supply your local HVAC corporation a call right away. Your specialist will be able to inspect the problem and have your plan respectfully thawed out.
