A working air conditioner will cool down your home, even on the hottest days of the summer. However, you may start to notice that the air conditioner is blowing hot air from your vents and making your home not feel so comfortable. Here are some reasons why that could be happening.
One common reason for warm air is a leak in the refrigerant lines. The air conditioner constantly moves refrigerant as it turns from a liquid to a gas, and having proper refrigerant levels in a pressurized line is key to the entire system running. If there is a leak somewhere within that line, it is going to lower the pressure and cause the air conditioner to not work nearly as efficiently as it could, resulting in warm is being pushed through your home.
You'll need to have an HVAC technician come to your home and try to find the leak. They will put a special dye into the system to identify where the refrigerant is coming out. The leak will be repaired, and then more refrigerant will be put into the until it has been properly pressurized again.
It may seem strange that frozen evaporator coils can actually cause the air conditioner to blow hot air, but it is true. This is because the evaporator coils actually works by removing the heat from the air before it is blown throughout your home. If the coil is frozen, it cannot absorb heat and do its job properly.
You can try turning off your air conditioner to let the coil thaw on its own, which may be enough to do the trick. However, if the coil continues to freeze, then you'll need to contact an HVAC technician to further investigate the problem.
Sometimes the problem is not with your HVAC system malfunctioning, but due to user error. It is always worth double checking the setting on your thermostat to make sure it is operating correctly. You would be surprised at how easy it is to enter the wrong temperature in a schedule through your thermostat smart phone app, or accidentally set the thermostat to heating instead of cooling.
There are also modes that will either heat or cool your home, depending on the temperature, and on a cool fall day the heat may be triggered without you knowing. You can also lock the keypad on a smart thermostat so that kids cannot change the settings. Contact a service, like Boyers R S Heating & Air Conditioning Inc, for more help.Share
