Indoor AC leaks are a common problem, and homeowners may face expensive repairs if the issue goes unaddressed or delayed. Leaky AC causes mold growth that can spread to other areas and may pollute indoor air. Moreover, your AC may experience reduced efficiency or break down due to water accumulation. Fixing a leak using a DIY method is possible with knowledge and expertise. However, most homeowners require expert help from an air conditioner service in Sacramento. Professionals have the technical expertise to suggest the best solutions for the problem. 

  • Cracked Drainage Pan:

Old ACs may have damaged drain pans prone to corrosion. Rust can damage the pan and leave holes for water leaks. You can temporarily use water adhesive to fix cracks and holes until the experts arrive. Consulting with an expert in cooling and heating repair in Sacramento can suggest the best solution to prevent damage in the future. Annual inspection and service can go a long way in protecting our AC units. 

  • Blocked Drain Pipes:

Drain pipes connected to the drain pan take extra water from the air conditioning system and push it outside. However, pipe clogs may occur due to sediment, mold, dirt, and other debris preventing the water flow. Consequently, the water from your system will overflow from the drain pan affecting the AC functioning.

  • Dirty Air Filter:

Air filters are important for smooth functioning. Dirty air filters reduce optimal airflow or adequate ventilation resulting in frozen evaporator coils. Consequently, excess water starts pooling in the drain pan leading to an overflow. It is best to replace your air filter because a clogged air filter takes an extra load to function, potentially leading to water leaks. Scheduled maintenance and inspection can help prevent expensive repairs arising from such problems.

  • Damaged Condensate Pump

Condensate pumps are necessary for some air conditioners to discharge water outside. A house’s drainage system installed above the air conditioner requires these pumps. However, a damaged pump can cause water accumulation in the drain pan leading to leaks. Also, old condensate pumps develop holes and cracks for water to pool in the drainage pan. An overflowing drainage pan can damage your drywall and ceiling. 

Also, setting your AC temperature as low as possible can be tempting. However, it puts stress on your AC unit in the long run. It is best to stop AC from overworking to prevent high utility bills and expensive repairs. 


Detecting AC leaks and employing the best solution on time is necessary to prevent expensive damage. Maintenance and inspection are required for the longevity of your appliance, increasing its peak performance. Right diagnosis saves you time, money, and hassle, ensuring indoor comfort all year round. Before it’s too late, call an expert and schedule your routine AC inspection to prevent costly repairs in the long run.
