A problematic air conditioner can cause significant discomfort during the hottest days of the year. The unit has to blow cool air, but it can be challenging for the entire household if it fails to function. If that’s the case, an air conditioning repair technician can diagnose the issue and offer a solution. Here are a few reasons why your unit may not be working properly.

Why Has Your HVAC System Stopped Working?

1. Clogged Air Filter

The air filter is designed to trap harmful particulates, such as dust mites, mold spores, and pet dander that would otherwise circulate throughout your home. Over time, those contaminants clog the filter and prevent air from flowing through it efficiently. As a result, the system works harder to cool your home, leaving it vulnerable to potential air conditioning repairs resulting from premature wear and tear. Replacing the filter every three months is best, or more regularly if you’re a pet owner.

2. Dirty Outdoor Unit

The outdoor unit houses the compressor, the condenser coil, and the fan. The refrigerant that flows through the compressor coils absorbs heat from inside the home and disperses it outside. This process ultimately cools your home down. 

However, when those components are contaminated with general outdoor grime, such as dirt, dust, leaves, and twigs, they become less functional over time. Clean the unit at least twice a year to prevent this problem by using a garden hose and a soft brush to rinse and sweep away debris gently. Otherwise, you may need to reach out to professionals for air conditioning repairs.

3. Low Refrigerant Levels

Without adequate refrigerant levels, the system won’t cool your home. The chemical absorbs heat and delivers cool air back to the home as it travels through the compressor coils and evaporator. However, refrigerant doesn’t just run out over time; the only way you may experience low levels is if there’s a leak. This concern is serious, as it indicates there is damage somewhere on the coils. An air conditioning repair contractor can resolve the problem, then recharge the refrigerant.
