As summer temperatures rise across St. Louis, your air conditioning system becomes more than just a comfort—it’s a necessity. June marks the start of the busy cooling season, which also makes it the ideal time to ensure your AC lines are in top condition.
Many homeowners may not realize that refrigerant lines and condensate drain lines play a critical role in keeping their system efficient and their home comfortable. By taking action early in the season, you can prevent mid-summer breakdowns, lower energy costs, and extend the life of your air conditioning system.

Understanding the Role of AC Lines
Your air conditioner relies on two key types of lines to function properly: refrigerant lines and drain lines. The refrigerant lines transport coolant between the indoor and outdoor units of your system, allowing it to absorb and release heat. If these lines become damaged, develop leaks, or lose insulation, the entire system can struggle to cool your home, leading to poor performance or even complete failure.
The condensate drain line is responsible for carrying away moisture that your AC removes from the air. When this line becomes clogged with dirt, mold, or algae, it can lead to water backing up into your system or your home—causing water damage, musty odors, and potential health risks from mold growth.
Why June Is the Best Time to Act
In St. Louis, summer heat and humidity can arrive quickly—and once July and August hit, HVAC service providers are often overwhelmed with emergency calls. Scheduling a preventive inspection in June allows you to beat the rush and address any hidden issues before your AC is working overtime.
Temperatures in June are already warm enough to detect performance issues, but not so high that a malfunction would leave your home unbearably hot. It’s a window of opportunity to act proactively—especially if your AC hasn’t been serviced in a year or more.
Warning Signs of AC Line Issues
While routine maintenance is always a smart move, there are also a few symptoms homeowners can watch for that suggest your AC lines may already need attention:
- Reduced cooling performance: If your home isn’t getting as cool as it should, refrigerant loss or insulation deterioration could be to blame.
- Higher energy bills: Struggling systems use more energy, often due to refrigerant line inefficiencies.
- Water pooling near the unit: A clogged drain line can cause condensate overflow, leading to water damage.
- Unusual noises: Hissing sounds may indicate a refrigerant leak, while gurgling could point to a drain issue.
