Common Air Conditioner Problems You May Face This Summer

Here are several of the most common air conditioning issues:

Air Conditioner Is Not Turning On

The air conditioner might be completely unresponsive if its circuit breaker tripped. It needs to be reset before you try to turn on our system again. Check if it has a loose plug, and re-plug as needed. Change the batteries in the thermostat if the current ones are dead. Call an HVAC professional for proper diagnosis and repair if the AC problem persists.

It is normal to hear a constant hum from your air conditioner. However, be wary of strange noises. Listen carefully to the sound as each kind points to a specific problem. For example, rattling sounds may be because of the motor assembly, while clicking noises are due to relay issues. Buzzing can be traced to electrical faults while hissing sounds point to a leak. HVAC technicians will know the problem as soon as they hear the noises from your air conditioner.

Air Conditioner Not Blowing Cold Air

A central air conditioning system fills your home with cooler air. If it fails to do its job, check if the air filter is clogged with dirt. This can block the airflow throughout your unit. As a result, the condenser may freeze, reducing the cooling ability of your AC. Prevent this problem by regularly replacing your air conditioner’s filters.

AC Refrigerant Leak

The refrigerant is the cooling system’s lifeblood. A leak means the air conditioner will experience issues with its efficiency and performance. There will also be an increase in energy consumption and uneven cooling around your home. The coils may also freeze, and the compressor may be damaged. Regular upkeep lets you know of possible refrigerant leaks so they can be resolved early.

Continuous airflow is needed so your evaporator coil doesn’t freeze. If this problem occurs, you must check the entire coil for clogs. The blockage may be because of dirty filters, a broken fan, or clogged vents. Avoid this problem through periodic cleaning and maintenance.

Electric Control Failure

Air conditioners operate best when running at a steady state. Its parts, especially the compressor, will experience faster wear and tear if it cycles frequently. Other components that can be affected are the fan motor and blower motor controls. These issues can cause the electric control to fail, preventing the affected parts from responding.

Air Conditioner Leaking Water Outside

Humid days can cause condensation in the coils. The moisture typically escapes out of the air conditioner through a specially designed drain duct. However, leaks can happen if the duct becomes clogged or damaged. Leakage can also happen if there are blocked drain pipes, improperly installed ducts, or a broken condensate pan, among other causes. Ensure that the inside is clean to prevent and resolve this issue.

Drainage Problem

Poor drainage results in the air conditioner having stagnant water inside it. This encourages fungi and bacteria to grow, eventually leading to foul smells spreading throughout your house. It is unpleasant and unhealthy to stay in a home with such a situation. Have a professional inspect and maintain your air conditioner to keep bad odors from developing.

Sensor Problem

Thermostat sensors detect the current temperature. Air conditioners will switch on if the room is too warm and switch off when it gets too cold. If the sensor is placed incorrectly, you may get faulty readings. An experienced HVAC technician can properly resolve their placement problems and calibrate them to ensure optimum function.

Easy Steps To Prevent Air Conditioner Problems

Here are four easy steps you can take to keep AC problems at bay:

  1. Inspect the HVAC filter: Many problems emerge from having dirty AC filters. Take the manufacturers’ advice and conduct regular air filter replacements. This is one of the best ways to prevent problems with your cooling unit. The recommended replacements are once a month or every three months. Let your filter’s condition guide you. Change it if the filter surface is clogged even before the scheduled replacement date.
  2. Clean the condensing unit: The outdoor unit is constantly exposed to dust and dirt. Dirty coils cannot effectively transfer heat outside. Cleaning the surfaces periodically is an easy way to fix this. Remove any objects on it as well, such as trash, leaves, and branches.
  3. Make sure that nothing is blocking the vents: Air can flow freely if the vents are open, so they should always remain that way. However, there may be times when objects are blocking the vents, resulting in poor airflow. Ensure no furniture, curtains, plants, or other objects are blocking them. Keep a watchful eye on these sensitive areas so you can immediately remove or reposition objects that are blocking them if needed.
  4. Install a programmable thermostat: Consider replacing old thermostats with new models. This way, you get better calibration and performance. Switch to a programmable thermostat if possible. You can set the timers per your preferred temperature and schedule. This helps in improving the unit’s precision while lowering your energy usage.
