1. AC Not Functioning at All

One of the most common and frustrating problems homeowners encounter is when the AC unit fails to work altogether. This issue can be attributed to various factors. These include power-related issues such as tripped circuit breakers or blown fuses. Faulty wiring or loose connections can also be behind it. Another probable cause could be a malfunctioning thermostat. When it fails to send the proper signals to the AC unit, it can cause a complete shutdown of the entire unit. Additionally, a defective capacitor, responsible for initiating the compressor and fan motors, can also be behind your AC not working. These can prevent the unit from getting the necessary power to start up. Lastly, a malfunctioning blower motor due to a faulty motor, broken belt, or control board issue can cut airflow. To address this problem effectively, it is advisable to seek the help of a professional HVAC technician. They can fix the underlying issue, ensuring a proper restoration of functionality.

2. AC Is Giving Warm or Hot Air

Your air conditioning system can blow warm or hot air due to several factors. One possibility is a refrigerant leak. It hinders the AC unit’s ability to cool the air efficiently. Inadequate refrigerant levels reduce cooling capacity and the circulation of warm air. Another cause could be a malfunctioning compressor. It functions to compress the refrigerant and facilitate heat transfer. If it is faulty, it may not cool the air properly, causing the circulation of warm air. Besides this, if the air filter is clogged, it restricts airflow. It hinders the cooling process and causes warmer air to come out of the vents. Lastly, a wrong-sized AC unit will also be unable to effectively cool the space. It results in inadequate cooling and warm air supply. 

3. Your Unit Is Leaking

AC unit leaks can occur for various reasons. A major culprit is a blocked or clogged condensate drain line. Over time, dirt, debris, and algae can collect in the drain line. They obstruct proper drainage and cause water to overflow and leak. Another possibility is a damaged or cracked condensate pan. This pan collects the condensation produced by the AC unit. If it is compromised, water can escape and result in leakage. Besides the above, a refrigerant leak can cause water to form around the AC unit. It is crucial to address refrigerant leaks promptly, as they can pose environmental risks. Moreover, they can impair the AC unit’s performance. Another reason can be Frozen Evaporator Coils. These can cause water to leak when they melt. It can be caused due to restricted airflow, Dirty Air Filters, or low refrigerant levels. If you notice water leakage from your AC unit, contact a professional HVAC technician to assess the situation. They can perform the necessary repairs, such as unclogging the drain line, replacing the condensate pan, fixing refrigerant leaks, or addressing frozen evaporator coils. Timely action will help prevent further damage and ensure the good functioning of your unit

4. Uneven Temperature Distribution

Inconsistent temperature levels throughout your home can be caused by improper or inadequate insulation in some regions. Insufficient insulation lets cold or hot air escape. It, in turn, causes Uneven Temperature Distribution. Another reason is poorly sealed air ducts. Leaks in the ductwork can result in conditioned air escaping before it reaches specific rooms. It results in temperature discrepancies. If your HVAC system is of incorrect size, it can also contribute to uneven cooling or heating. An undersized unit struggles to adequately cool or heat the entire space. It results in uneven temperature distribution. On the other hand, an oversized unit may cycle on and off too quickly. It fails to distribute air evenly throughout the home. Other factors leading to temperature imbalances include blocked or closed vents in certain rooms. Besides them, improper airflow due to dirty air filters and malfunctioning thermostats can also result in this problem.
