Air Conditioner Blowing Warm Air
There are several reasons your AC could be blowing warm air. First, check that the thermostat is set to cold and functioning properly. Another common reason for warm AC air is a dirty filter, which can clog up your unit and possibly freeze the condenser. Check your air filter, and consider calling the HVAC Heroes for a total AC tune-up. This affordable maintenance visit can save you hundreds in AC repair down the road.
Ac Freezing Up
AC Freezing up outside of the unit is a common problem with many causes, such as insufficient airflow, low outside temperature, low coolant levels, or a problem with the air controller. Whatever the reason, if you notice that your AC is freezing up it is best to get a professional out to maintain it ASAP.
Ac Not Turning On
You go to turn your AC on, but nothing happens. There is no need to panic yet– there are a lot of easy, fixable reasons your AC may not be turning on. First, check that your thermostat has fresh batteries. If the batteries are in working condition, check the settings. Be sure that the thermostat is set to cold, at least a few degrees colder than ambient air. If it is still not working, check that the circuit breaker isn’t tripped.
Refrigerant Leak
The coolant is the component of your AC that cools the incoming air. If your coolant has begun to leak, your AC will not function properly. If you notice higher power bills but less cold air or uneven cooling, check your AC unit for refrigerant leaks. Refrigerants can be dangerous, so if you notice a leak it is best to call a professional to check it out.
Water Leak
If you are using your AC on a hot day, it is normal to see a small amount of water leaking, caused by condensation on the coil. However, if you notice a large amount of water, it is a sign that something is wrong with your AC unit. It could be a backup from dirty air filters, low coolant levels or a broken condensate pan. If your AC was recently installed, pooling water could indicate improper installation. Pooled water can cause mold, mildew and severe property damage if left untreated, so treat pooling water seriously.
Drainage Issues
The drainage system of your AC removes condensation and prevents pooling water. Sometimes that drainage pipeline can become clogged with algae, dirt or dust. This backup of water can allow smelly mold and fungus to take hold near the air intake, and fill your air with a musty, stinky smell. To prevent this, make sure that your drainage system is regularly maintained and cleaned.
Sensor Issues
In order to monitor the air temperature, all AC’s have a thermostat sensor that is located near the evaporator coil. This sensor is used to measure air temperature in the evaporating coil and adjust cooling accordingly. If this sensor malfunctions, it could cause your AC to randomly turn off and on, or not emit the correct temperature of air.
Strange Noises
AC’s are generally fairly quiet, or emit a steady hum. If you notice a strange new sound, it could be a malfunction with your machine. Different sounds indicate different issues– a hissing sound could be a refrigerant leak. If you turn off and on your AC and hear a clicking sound, it is likely a relay issue. Any screeching noises are likely from an off-balance fan in the fan motor or compressor, and faulty electrical components make a buzzing sound. Any other thumping, rattling, or metal-on-metal sounds could indicate something loose in the blower or motor assembly.
