When the summer heat is at its peak, a malfunctioning air conditioner can quickly turn your home into an uncomfortable space. As a trusted provider of HVAC services in Asheville, NC, we often hear from customers experiencing issues with their AC units not turning on. Let’s explore some of the most common reasons why this might happen and what steps you can take to address these problems.

Tripped Circuit Breaker

This one may seem obvious, but one of the most common reasons your AC won’t turn on is a tripped circuit breaker. Your AC unit requires a significant amount of power, and if there’s an electrical surge or overload, the breaker might trip to prevent damage. To check, locate your electrical panel and see if the switch labeled for your AC is in the “off” position. Simply flip it back to “on” and see if this resolves the issue.

Thermostat Issues

Sometimes, the problem lies with the thermostat rather than the AC unit itself. Ensure that your thermostat is set to “cool” and the temperature is set lower than the current room temperature. Additionally, check if the batteries need replacing. A malfunctioning thermostat can easily prevent your AC from turning on.

Clogged Air Filter

Air filters play a crucial role in maintaining your AC unit’s efficiency. Over time, these filters can become clogged with dust and debris, restricting airflow and causing your AC to shut down. Regularly replacing or cleaning your air filters can help maintain proper airflow and prevent your AC from failing to turn on.

Dirty Condenser Coils

The condenser coils in your outdoor unit can accumulate dirt and debris, which can hinder the cooling process. If the coils are too dirty, the unit may overheat and shut down as a safety measure. Regular maintenance, including cleaning the condenser coils, can prevent this issue and keep your AC running smoothly. You can sign up for our annual maintenance plan to prevent these types of issues and keep your home cool year round.

Faulty Capacitor

The capacitor in your AC unit provides the necessary power to start the motor and keep it running. If the capacitor is faulty, your AC may struggle to turn on or stay running. This is a technical issue that requires a professional technician to diagnose and replace the capacitor if needed. If this is the case, we are happy to help with all of your AC repair needs.

Refrigerant Leaks

Refrigerant is essential for your AC to cool the air effectively. If there’s a leak, the refrigerant levels can drop, causing your AC to malfunction or not turn on at all. Signs of a refrigerant leak include hissing sounds, ice buildup on the unit, or decreased cooling efficiency. Addressing refrigerant leaks requires professional attention, as handling refrigerants can be hazardous.

Compressor Problems

The compressor is the heart of your AC system, and if it fails, your AC won’t be able to cool your home. Compressor issues can arise from electrical problems, refrigerant issues, or general wear and tear. Repairing or replacing a compressor is a complex task that should be handled by a qualified technician.
