Imagine – you’ve been outside working in your yard all afternoon and when you walk into your Greenville, SC home waiting for the cold air to cool you down, the house is warm. The air coming from your vents isn’t cold but warm. For some reason, your air conditioner is blowing hot air into your home. Unfortunately, this happens more frequently than we’d like and the Eastergard HVAC team is here to help. Below, we will discuss some of the top possible reasons as to why your air conditioner is blowing warm air and what you can do about it. Refrigerant is Low Refrigerant is responsible for absorbing heat from your Greenville, SC home’s air. If it leaks, your air conditioner will struggle to cool the air in your home. You’ll know you have a refrigerant leak if your indoor and outdoor AC units have ice forming on them. If you suspect that your cooling system is low on refrigerant, it’s important to call in HVAC professionals for help. Faulty Thermostat Believe it or not, you may be getting warm air from your AC unit because your thermostat is set to “heat” instead of “cool”. Double check it and ensure it’s set to “cool”. In addition to the proper cooling setting, your fan needs to also be in the correct setting. Make sure it’s set to “auto”, not “on”. When it’s set to “on”, it will blow warm air through your home when your air conditioner is in between cooling cycles. Dirty Air Filters While this might seem too simple to cause warm air coming from your AC unit, it happens more than you’d think. Dirty air filters clog the airflow throughout your HVAC system which can hinder the performance of your air conditioner. Make sure your air filters are clean and that they are changed out every 1-3 months to ensure proper airflow and maximum comfort in your Greenville, SC home this summer. Loss of Power Finally, your cooling system might be blowing warm air because the outdoor unit has lost power. If the air handler is working fine, the fan will still blow air into your home. However without the outdoor unit working properly, there will be no cooling. Your outdoor unit might have lost power due to a blown fuse or a tripped circuit breaker.
