If your thermostat settings are correct, there are a couple components you can check that may be causing your unit to blow out warm instead of cold air. First, find your indoor unit which is referred to as an “air handler” or “furnace.” This unit is usually where you change your filter and may be in the attic, basement, or closet. Check the filter to ensure that it’s clean; if clogged or dirty replace it immediately as this can cause a unit to stop operating properly. Next, look for signs of water either in the safety drain pan under the unit or in the drain pump near the unit. These two items are usually equipped with safety overflow switches and if water has backed up it will cause your unit to shut down before overflowing. Finally, listen to the indoor unit, do you hear the fan running? If not then there may be an electrical problem preventing your unit from operating and if this is the case call Bardi to find out the exact source and remedy options.
Another way to investigate why your air conditioner is blowing hot air is checking your outdoor unit or “condenser,” which works to reject heat gathered from your home using refrigerant during the air conditioning process. If the condenser is unable to effectively reject this heat, it can cause the refrigerant pump (also known as a “compressor”) to overheat and shutdown. Look to see if the fan on the condenser is running. This fan pulls heat away from the condenser and if it stops working it’ll need repairing or replacing. Also look at the silver or black fins that wrap around the unit known as the “condenser coil,” which may be protected by a louvered hail guard. If this coil becomes impacted with dirt, grass clippings, lint, or animal hair it acts as a blanket and results in the removal of heat. This coil should be cleaned seasonally and never have a visual buildup of debris on it. Another strategy is to find the two copper refrigerant lines that connect to your outdoor unit — one will be larger and covered in black foam. Gently slide the foam back and feel the larger line (it should be cold to the touch). If you find that this line is either warm or iced over, then there is a problem and you should schedule a Bardi solution expert to resolve it.
