3 Common Culprits of Air Conditioner Failure, La Crosse, Wisconsin

If your HVAC system breaks down in the dead of summer, prompt air conditioner repair will restore your family’s comfort. It’s crucial to know some common causes of HVAC failure so you can take steps to prevent such issues altogether. 

What Might Cause an AC to Malfunction?

1. Dirty Coils

air conditioner repairWhen a unit’s condenser coils get coated in dust, oil, or grime, the system has to work a lot harder to dispel heat. The dirty coating essentially insulates the coils, thereby inhibiting them from eliminating hot air effectively.

If left unchecked, the unit will eventually overwork itself to the point of total system failure, and it will take more than just cleaning the coils to restore functionality—you’ll need comprehensive air conditioner repair. 

2. Leaky Ducts

Central AC systems rely on ducts to transport cool air throughout the structure. When duct systems are first installed, they’re entirely sealed to ensure optimal efficiency.

Over time, however, small leaks or gaps can develop between the metal panels, causing the cool air to escape before it’s reached its destination. When this happens, the AC has to work even harder to maintain a consistent temperature, which can speed up its wear and tear. 

3. Low Refrigerant 

Low refrigerant is a common cause of HVAC issues, as it’s responsible for eliminating heat and moisture from the air. If a leak develops in one of the refrigerant lines, the unit will no longer be able to produce cool air until the damage is repaired and the refrigerant is topped off.
