The average lifespan of an AC unit is about 15 years. But, over time, your AC unit will start to show signs of wear and tear. If you don’t keep up with regular maintenance, your AC unit could fail much sooner than 15 years.
There are a number of reasons why AC units fail. In this blog post, we’ll discuss 8 common causes of AC unit failures.
1. Lack of Maintenance
One of the most common causes of AC unit failures is lack of maintenance. Just like any other appliance in your home, your AC unit needs to be regularly maintained in order to function properly. Neglecting to do so can cause a number of problems, including
- Reduced efficiency
- Shortened lifespan
- Decreased cooling capacity
Schedule AC services in Cartersville, GA at least once a year to clean the coils and clear the drain line. This will help your AC unit run more efficiently and prolong its lifespan.
2. Dirty Air Filters
Another common cause of AC unit failures is dirty air filters. Your AC unit’s air filter catches dust, dirt, and other airborne particles. Over time, the filter can become clogged, which can restrict airflow and cause your AC unit to work harder than it needs to. As a result, your AC unit could overheat and fail.
3. Frozen Evaporator Coils
Another common problem that can cause AC unit failures is frozen evaporator coils. This usually happens when there’s a problem with the airflow in your AC unit. If the airflow is restricted, the evaporator coils can ice over, which can reduce the cooling capacity of your AC unit.
4. Leaking Refrigerant
If your AC unit is leaking refrigerant, it could be a sign of a serious problem. Refrigerant is what makes your AC unit cool, so if it’s leaking, your AC unit won’t be able to do its job properly. In some cases, a leak can be fixed by simply recharging the refrigerant levels. But in other cases, the leak may be due to a more serious problem, such as a hole in the refrigerant line. If you suspect that your AC unit is leaking refrigerant, call an HVAC technician right away.
5. Electrical Problems
Another common cause of AC unit failures is electrical problems. Over time, the wiring in your AC unit can become loose or damaged. This can cause a number of problems, including
- Reduced cooling capacity
- Shortened lifespan
- Fires (in extreme cases)
If you suspect that there’s an electrical problem with your AC unit, schedule AC repair in Cartersville, GA right away. They’ll be able to diagnose the problem and make the necessary repairs.
6. Thermostat Issues
Another common cause of AC unit failures is thermostat issues. If your thermostat isn’t working properly, it can cause a number of problems, including:
- Reduced cooling capacity
- Inaccurate temperature readings
- Wasted energy
If you suspect that your thermostat may be to blame for your AC unit’s failure, it’s important to have it checked and replaced by a professional as soon as possible.
7. Dirty Coils
Dirty coils are another common cause of AC unit failures. When the coils in your AC unit become clogged with dirt and dust, they can’t effectively transfer heat, which can lead to a number of problems, including
- Poor air quality
- Wasted energy
If you think dirty coils may be the cause of your AC unit’s failure, it’s important to have them cleaned by a professional as soon as possible.
8. Broken Fan Blades
The fan blades in your air conditioner can break for a variety of reasons. Sometimes, the blades can become bent or damaged by debris. Other times, the blades can simply wear out over time and need to be replaced. If your fan blades are broken, it can cause your air conditioner to make strange noises or not work properly. Some of the signs that you have broken fan blades include:
- AC unit making strange noises
- Unit not cooling properly
- Unit not blowing air correctly
