Chattanooga AC blowing hot air

Why Are My Vents Blowing Hot Air?

One of the most frustrating, and common things you have to deal with as a homeowner is problems with your air conditioning system. When you turn that air conditioning system on, and all you feel is warm air, what is the cause of this problem?  There is no one singular issue that you are likely going to be able to point to right away. Warm air coming out of an HVAC  could be caused by a variety of things. It could be something incredibly simple, but it could also be something very complex, a major repair that needs to take place. Having knowledge of some of the possible causes can help you as a homeowner in knowing what to do, what to try, and what could be where the issues are stemming from.

Check the Thermostat

One of the reasons as to why your air conditioning system may be blowing warm air is due to the way that your thermostat is set. This may sound quite ridiculous, but you could not believe how many times we have seen customers think their system was broken, only to find the thermometer was set wrong. Make sure that you have your thermostat set to “cool” instead of “heat.” In the event, it is on “heat,” that is why you have warm air.

Check the setting of “auto” and “on” as well. When you have it set to “on” the blower is just going to continue to go, and what is going to come out of it is likely going just to be warm air that is pushed around. “Auto” is when the system will kick on with cold air to get you to your desired temperature.

Electrical Issues

The outdoor and indoor units needs to be working together. When the outdoor unit is not functioning, it could be a result of a blown a fuse or a circuit breaker that has tripped. When this occurs, the unit outside is not going to run. Reach out to us in this case so that we can help you fix this electrical issue in a safe and efficient manner.

Out of Refrigerant

An air conditioning system needs refrigerant to cool the air that you have coming out of it. When the refrigerant is low or has run out entirely, the air that is coming out of the system is not going to be cold, simple as that. The refrigerant levels can be recharged, but you are also going to want us to make sure there is no leak.
