There’s nothing worse than having a failing air conditioner, especially with summer right around the corner. There are many reasons why an air conditioner can fail. That’s why it’s important to know what to keep an eye out for, whether it’s frozen evaporator coils or lingering debris. Here is the ultimate guide to preventing air conditioner failure.
Routinely Replace the Air Filter
The air filter in your system may seem too simple to cause any damage. However, you’d be surprised at how many problems a dirty air filter can cause. Without changing the air filter on a routine basis, it can increase your energy bills, strain your system and even lead to total breakdowns.
Clear Out Debris From the Outdoor Unit
Leaves, twigs, and other outdoor debris can clog your outdoor condenser, leading to system strain and eventual failure. Keep the area within two feet of your outdoor unit clear of debris, and keep the nearby grass trimmed.
Check for Frozen Evaporator Coils
The evaporator coils help cool the air that comes into your home, but they can become frozen due to poor airflow. Issues like a clogged air filter, faulty blower fan and blocked vents make it harder for your system to push air through the ducts, which leads to excess condensation that freezes your evaporator coils.
If you think your coils are frozen, you can shut off the AC and allow them to thaw on their own. However, it’s important to get to the bottom of the issue, which is why you should call a professional HVAC technician to inspect your system.
Keep Vents Open
Closed vents can reduce HVAC efficiency by restricting ventilation and depressing airflow. Make sure the vents aren’t obstructed by furniture, curtains or rugs. While closing vents may be beneficial in some aspects, it’s usually best to keep them open so air can circulate freely throughout your home.
Subtle Warning Signs of AC Failure
Now that you know the possible causes of AC failure, here are some of the red flags to watch out for. Even if some of them seem like minor problems, they’re clear indications that your AC needs care.
- Strange noises coming from the vents or units
- Weak airflow
- Insufficient cooling
- Foul odors
- High humidity levels
- Short-cycling (system goes on and off rapidly without reaching the desired temperature)
Any of these issues is a sign you should call a professional technician to take a look at your air conditioner. It’s always better to reach out early and take preventive measures before your AC shuts down completely.
