Electrical Issues and Your AC’s Performance

Your HVAC system relies on electrical components to operate properly. If your air conditioner keeps turning off and on, it could be short cycling due to an electrical issue. Common culprits include a faulty capacitor, loose wiring, a malfunctioning thermostat, or a tripped breaker. If your system won’t start at all, check your breaker panel—resetting the breaker might restore power. But if the problem keeps coming back, it’s best to call a professional. Atlanta HVAC 911 offers expert HVAC repair in McDonough, GA. We’ll inspect your system, identify the source of the electrical issue, and fix it before it causes further damage or poses a fire risk.

Why Running an AC with a Frozen Evaporator Coil Is a Bad Idea

If your AC suddenly stops cooling, check to see if ice has formed on the evaporator coil. This typically happens due to restricted airflow or low refrigerant levels. Running your air conditioner while the coil is frozen can lead to major damage, including compressor failure. Turn off your system and allow the coil to thaw before restarting it. However, melting the ice won’t solve the underlying issue. A frozen coil is often a symptom of a bigger problem, such as a clogged filter, blocked air ducts, or a malfunctioning blower motor. Atlanta HVAC 911 can diagnose the cause and provide air conditioning repair in McDonough to prevent future damage and avoid premature system replacement.

How Dirty Air Filters Can Lead to Major AC Problems

Clogged air filters restrict airflow and force your HVAC system to work harder than it should. This can result in higher energy bills, poor indoor air quality, and eventually a breakdown. If you notice weak airflow or hot spots in your home, your air filter might be the problem. Filters should be replaced every 1 to 3 months to keep your system running smoothly. If changing the filter doesn’t help, the issue may be deeper in your system. Atlanta HVAC 911 provides thorough AC repair services in McDonough to handle airflow issues and get your system back on track fast.
