Most Common AC Problems You Could Face

For every homeowner, frequent air conditioner repairs or a replacement can be costly. And as we approach the hot months, you don't want to find yourself indoors without a fully functional AC system. To enjoy optimal AC performance during the hot season and prevent breakdowns, you'll need to know the common AC problems.

Being aware of the common AC problems can help you take better care of your AC for extended trouble-free service life. Also, if you know the signals when your AC needs repair or tune-up, you'll take timely action to prevent small problems from turning into expensive repairs, AC failure, or whole system replacement. Here are the common AC issues to watch out for.

Refrigerant Leaks

Refrigerant is a chemical compound that runs through the evaporators and compressors of your AC to remove heat and humidity in a room.



If the AC system develops leaks and the refrigerant levels fall below a certain level, your AC may operate less efficiently. Your AC will have to overwork to cool your home effectively, increasing your utility bills. If you continue using your AC with low refrigerant levels, serious damage may result to the compressor motor warranting an expensive replacement.

Some common signs of AC refrigerant leaks include poor cooling, humid indoor air, frozen coils, long cooling cycles, and hissing or bubbling sounds. If you notice these signs, contact an HVAC repair expert who will inspect your unit for leaks and carry out the necessary repairs

Blowing Warm or Hot Air

When you turn on your AC, you expect the air around your home to cool down. However, due to clogged air filters, dirty evaporator coils, a faulty compressor, leaks, or thermostat settings, your AC may blow out hot air and make your indoors inhabitable.

If your AC blows hot air, the unit might only need a minor fix, but make sure to work with a professional HVAC repair service. If you ignore the problem, you may incur costly repairs down the line. Also, even when your unit is operating properly, schedule regular AC inspections to replace air filters, check for leaks, and clean the unit to prevent hot air from blowing out.

AC Not Turning On

If you switch on your AC, but it won't work, confirm the unit is plugged in and check if the thermostat batteries are dead. If the batteries are working properly, ensure the thermostat settings are correct. If the unit won't turn on, a tripped circuit breaker could be the culprit.

If none of these simple solutions remedy the problem, seek help from a reliable HVAC technician. These experts will troubleshoot your unit to determine why the system won't turn on. Soon enough, your unit will be back up humming to cool your living space.

Weird Noises

When working properly, your AC produces a faint, constant blowing sound and may click slightly when you turn it on or off. But if you hear any other strange noises, something is off. Take note of banging, screeching, buzzing, rattling, clanking, hissing, or bubbling noises. Each sound signals a unique problem, and an HVAC expert will help diagnose and solve the root cause.

Your AC may produce noises due to loose components, faulty electrical parts, faulty compressor, leaks, or debris stuck inside the unit.

Water Leaks

If you see water dripping down your AC, your unit might need a fix. AC leaking may indicate dirty air filter, blocked drain pipe, improper installation, faulty condensate pipe, or low coolant levels. If you suspect your AC is leaking, contact an expert to check if the water leak is normal or not.
