It can be really frustrating when it is so hot in your home and you just can’t seem to cool down. It is even more frustrating when you are hot and your air conditioner is on. Even though you can hear that your air conditioner is on and everything sounds normal, all you feel from the vents is hot air. You check the temperature on your thermostat only to find it really is as hot in your home as you think it is.
There are many reasons your air conditioner is blowing hot air, and a few of the problems that make this happen are easily fixed. Some can be fixed without needing to call your HVAC company. Total Care Heating and Air, your AC service in San Bernardino, offers you the reasons your air conditioner is blowing out hot hair.
Issues with the Thermostat
The first thing you need to check when your air conditioning unit is blowing hot air is the thermostat. It could be something as silly as not being properly set or a dead battery.
Believe it or not, people other than yourself do mess with the thermostat. Kids might think it is too hot in the house and think they are doing everyone in the home a favor by tinkering with the thermostat.
The thermostat could also be bumped and that is the cause of your problems.
Check the Filter
One of the most common problems that impedes cooling operations is reduced air flow. If you notice your air conditioner is blowing hot air, check the filters.
Your air conditioning unit is designed to remove first and dust in the air as it flows through the system. But when the air filter gets too dirty, it clogs up and impedes airflow through the system. When this happens, the coils cannot remove heat, so you are stuck with hot air flowing through your HVAC system and through your home.
Blocked Return Vents
This is another airflow issue that can result in your air conditioning unit to blow hot air. There is always the possibility that someone either closed the return vents in your home or some have been blocked. Either way, this could be the cause of your problems.
Before calling your HVAC professionals, take a look around the house and make sure all of the vents or unblocked and open.
It is also a possibility that you have ducts that are leaking or disconnected. If this is the case, return air might not be getting back to the air conditioning unit and the result will be a stream of hot air coming from the vents.
If your ducts are accessible, you might want to take the time to look them over to see if there are issues that you can easily fix. If not, then you will need to call in the experts.
Outdoor unit Loses Power
Many HVAC systems have indoor air units and outdoor condensing units. If your air conditioner is blowing hot air, it could be because the condenser is not properly working or it somehow got shut off. A blown fuse or a tripped circuit breaker could be the problem, which is easily fixed.
It might be some other electrical issue as well. If this is the case, don’t try to fix it yourself, this can be too dangerous, Instead, call in a professional who knows what they are doing.
Dirty Condenser Coils
Your condenser coils are a critical part of your air conditioning unit as they are responsible for releasing heat to the outside of your home. But because they are outdoors and exposed to the elements, it is not uncommon that they get dirty. And when this happens, it could cause them to not properly work.
If this is the case, the condenser coils need to be cleaned.
The refrigerant is the stuff that flows through your air conditioning unit and makes everything cool. It is in a sealed loop so there should never be the need to add it to your unit. If you are in need of more refrigerant, it is because you have a leak that needs to be repaired.
If this is the case, call Total Care Heating and Air right away.
