Imagine coming home after a tiring day at work on a scorching summer day, looking forward to relaxing in the cool comfort of your home, only to realize that your AC isn’t blowing cold air. That would certainly be frustrating and annoying. What causes this air conditioner problem and how can you prevent this issue in the first place? Keep reading to learn more!
Reasons Why AC Is Not Blowing Cold Air
When your AC is not blowing cold air, the first step is to check the thermostat. It’s possible there could have been be a mistake when setting up your thermostat. If that’s the case, then it’s an easy fix. Simply change the settings to your desired temperature and ensure it’s set to “cool.”
If all the right settings are in place, then a malfunctioning thermostat might be the issue. This can indicate there might be an internal problem with the thermostat. In this case, call your local professional for help!
Another reason why your AC may not be blowing cold air is blockages. Any blockage in the system can hinder the effectiveness of the air conditioner. Blockages can happen in many AC components, particularly in the condenser coil and the air filter.
Always make sure to check the air filter for any debris, such as dirt, that has accumulated and caused a blockage. Regularly cleaning and replacing your air filter ensures it remains clean and clear, allowing air to flow smoothly.
The condenser coil, located in the outdoor part of the AC, is the other component that can easily clog. Any debris in the coil can force your air conditioner to work harder and disrupt the airflow, leading to reduced efficiency.
Remember that clogged systems not only cause the airflow but also result in the system working harder and, therefore, using more energy which will cause you more in the end.
An ineffective air conditioner can indicate many problems within the system, ranging from minor or major issues, including when your AC is not blowing cold air like it is supposed to. Like any other system, ACs will experience wear and tear over time. This is typically when things can start to go south, especially if not well-maintained.
It’s not uncommon for equipment to become damaged in an older system, so if you have an aging unit and notice dwindling performance, it’s advisable to have a professional check the entire system.
Regular maintenance can extend the lifespan of your AC and help you save money in the long run. However, this isn’t limited to old systems only. Even newer air conditioners also require regular check-ups to ensure it runs smoothly and prevent significant damage.
A refrigerant is a substance that can absorb heat from the inside and release it outside, thus cooling down the indoor air. Leaky refrigerants make the system unable to absorb heat effectively, which results in a loss of cool air.
Some tell-tale signs may indicate a refrigerant leak, such as a hissing noise from the system and a longer duration than usual for the air conditioner to cool the room. If you notice any of these signs, contact your trusted HVAC specialists.
Evaporator Coil is Frozen
The last item you should check when your AC is not blowing cold air is the evaporator coil. The evaporator coil is one component that can freeze due to lack of airflow, which can cause the coil to become too cold and freeze over. When this occurs, it can damage the compressor, reduce cooling effectiveness, and result in higher energy bills due to the system working harder than usual. Additionally, ice build-up on the coil is also an obvious sign of a frozen evaporator coil.
