During the scorching summer months, we all rely on our central air conditioning systems to help keep our homes cool and cozy. However, if you see water pooling around your AC unit, it could be a sign of a problem. Central AC units are designed to remove moisture from the air, but when something goes wrong, the unit can start to leak water. This can be a frustrating and potentially expensive problem to deal with, but the good news is that the causes are often easily identifiable and fixable. In this blog, we'll explore the 7 common causes of why your central AC unit leaks water and what you can do to prevent it.
  1. Clogged drain line: Over time, dirt, debris, and other particles can accumulate in your AC system's drain line, causing it to become clogged. Water can back up and leak out of the unit when this happens.
  2. Dirty air filter: When an air filter becomes clogged with dirt and debris, it causes your air conditioning system to freeze, potentially resulting in water leakage.
  3. Low refrigerant levels: If your AC is low on refrigerant, it causes the evaporator coil to freeze, eventually leading to water leakage.
  4. Damaged drain pan: If the drain pan under your AC is damaged, cracked, or rusted, it causes water to leak out of the unit.
  5. Improper installation: If your AC is not installed properly, it can lead to water leakage. A variety of factors, including incorrect placement of the unit or improper installation of the drain line, can cause this.
  6. Broken condensate pump: If your air conditioner has a condensate pump that's not working correctly, be aware that it could result in water flowing out of the system.
  7. High humidity levels: In areas with high humidity, it is common for AC units to produce more condensation, which can lead to water leakage.
Suppose you spot any water leaking from your air conditioning unit. In that case, it is critical to address the problem quickly in order to avoid additional harm to both the appliance and your house. To ensure that the difficulty gets resolved correctly, don't hesitate to get in touch with an experienced technician for AC repair services.

7 Maintenance Tips To Increase The Performance Of Your AC Unit

Maintaining your AC unit can optimize its performance, efficiency, and longevity - helping you save money on energy bills and potentially avoiding pricey repairs. Whether you own or rent a place, follow these tips to get the most out of your air conditioner!
  1. Change or clean air filters regularly: If you're not changing them often, they may become clogged with dust and debris. This blocks airflow to the AC, causing it to work harder than necessary in order to cool a room. To ensure that your AC is running efficiently, be sure to clean or replace the air filter regularly - this helps improve its performance significantly!
  2. Check refrigerant levels: Having your refrigerant levels regularly inspected by a professional is essential for keeping your air conditioning unit running at peak performance. Low refrigerant can cause the AC to strain and work inefficiently, so be sure to replenish the level of coolant if needed.
  3. Clean evaporator coils: It's essential to clean the evaporator coils of dirt and debris routinely. If left unclean, the system will be forced to work harder than necessary, leading to reduced efficiency. Therefore, take a few moments each month to tidy up those dirty coils!
  4. Inspect electrical connections: It is imperative to frequently examine its electrical connections for any signs of damage or looseness. If necessary, have them repaired or replaced immediately to avoid permanent breakdowns.
  5. Clean condenser unit: Accruing dirt and debris on your AC unit's condenser can significantly impede its performance; therefore, it is essential that you routinely clean the condenser of any accumulated particulates. Doing so will ensure maximum efficiency and long-term success!
  6. Check drain line: Regularly check and clear the drain line of all clogs or blockages. If left unchecked, a blocked drain causes water to back into the machine, resulting in costly damage.
  7. Schedule regular maintenance: Schedule regular AC maintenance service appointments with a reputable HVAC specialist. This will help them spot any potential problems at the earliest stages and perform preventive measures to ensure your air conditioning system operates optimally for years.
With these maintenance tips, you can improve the performance and efficacy of your air conditioner while saving on energy bills. Moreover, it'll help you stay away from expensive air conditioning repairs in the long run!
