Why Is My Central AC Running But Not Blowing Air
If you have central air conditioning in your home, you should know how important it is for you to keep the entire house comfortable when it’s blazing hot outside. But sometimes, you can come across some problems that are not only frustrating but also a bit tricky to solve such as the central AC not blowing air. You should leave these problems to air conditioning repair services. If you want to take it on, here are some potential problems along with solutions to help you keep the unit running.
Upon turning on your central air conditioner you notice that it is not blowing air, you should not dive into panic mode. Sometimes, the problem may be pretty simple and require no cost to fix. When the summer season hits, most homeowners tend to crank up their central air conditioning systems to the point where it burdens the power grid.
This is why summer seasons experience power cuts. It might also be that the settings on your thermostat have changed due to a power outage. If that is not the problem, check the circuit breaker and blown fuses. If found, you will need to replace them.
Although thermostat problems rarely contribute to central air conditioners not blowing air you should check just to be sure. Back in the day, thermostats would automatically reset and would need manual adjustment. However, today, thermostats have turned smart but can still lose calibration. If a thermostat is not calibrated, it will not read the temperatures properly and will misguide the central air conditioners.
Therefore, if your thermostat runs on batteries, you will need to replace them. However, if it is tricking the unit into thinking that it is too cold outside, you will need to consult an expert for calibration.
Clogged Air Conditioner Filters
Air filters are one of the most important components of a central air conditioning system. These air filters are made to keep the air clean and free from toxins and pollutants. This means they will need replacement after a while. Every manufacturer recommends a replacement schedule, which should be followed to ensure the unit runs as smoothly as possible.
If neglected, air filters can become choked due to dirt and dust accumulation. Not only that, the interior of the house will be exposed to harmful air. This could be alarming for the elderly or people who suffer from allergies. Therefore, you should regularly take out the air filters and ensure that they are clean. And if the air filters have simply given up, replace them.
Clean The Condenser Unit
A central air conditioner not blowing air could also be due to the condenser unit. The condenser unit is located outside and is exposed to dirt, debris, dust, and grime throughout its lifespan. That said, there is no surprise that it can become covered with dead leaves, shrubs, twigs, etc.
If that is the case, the condenser unit will fail to perform at its optimum and put the entire unit under stress. Therefore, depending on the usage frequency of your central air conditioner, inspect and clean the condenser unit. However, since a condenser unit utilizes high voltage electricity, you should hire an expert for the maintenance.
Check The Ductwork
Apart from the central air conditioning system, the ductwork also plays a crucial role in ensuring cool or hot air is transported indoors. With time, ductwork can develop cracks or minor damage allowing cool or hot air to escape. As a result, the air will escape through the cracks before it reaches your house.
It might also be that the ductwork was done by an inexperienced individual resulting in improper installation. Therefore, if you notice that the air conditioner is working but the air is not entering the house, you will need to consult an expert to check the ductwork.
In the end, troubleshooting a central air conditioning system can sometimes be simple and easy. However, if the above-mentioned tips do not help, it means the issue is relatively more complicated. Therefore, you will need to call in HVAC contractors McLean to help troubleshoot the issue. They will fix the issue more quickly and in a better manner.
