Have you ever found yourself wondering, “why is my air conditioner blowing warm air?” After all, a fully functional air conditioner is a must-have for every home in and around Chattanooga. Generally, air conditioners play a significant role in circulating and filtering the air we breathe in. Just a few other benefits of good air conditioning systems include preventing heat-related illness, filtering allergens out of the air, and preventing electronic devices from overheating.
On the other hand, having a faulty AC unit can be quite frustrating. Especially with summer just around the corner. Temperatures are usually unbearable during this season and you need comfortable, cool air more than ever. An air conditioner that blows warm air can give you sleepless nights unless you take immediate action.
Why Is My Air Conditioner Blowing Warm Air?
Well, your air conditioner can start blowing warm air due to various reasons. Let’s look at a few of them.
1. Clogged Filter
When your air conditioner has a good filter, contaminants such as dust and pet hair are filtered out of the air. When the filter becomes clogged by foreign substances, it prevents air from flowing through the system effectively. Your air conditioner may start blowing warm air if not enough air is passing over the condenser coils.
2. Thermostat Problems
The first thing that you should consider doing when your AC system starts blowing warm air is to check the thermostat. From time to time, thermostat components may break. Or, you may have changed the temperature accidentally. Is the thermostat set at the correct temperature and the air is still warm? Just call a professional to diagnose and repair the problem for you.
3. Disconnected or Damaged Wiring
If the wiring isn’t connected properly, your air conditioner will have a hard time functioning as it should. Whether the wires are damaged or simply disconnected, they need repair. Check for exposed or damaged wires. If you spot any, call a professional.
4. Low Refrigerant
Refrigerant is the substance that turns warm air into comfortable cool air. If it’s low, whether from a leak or otherwise, you’ll experience warm air coming from your vents. Your AC repairman will let you know if this is the problem.
Other Common Causes of AC Blowing Warm Air Include:
- Tripped condenser breakers
- Blocked return vent opening
- Blocked/dirty condenser coils
- Power loss to the system’s outdoor unit
