HVAC systems are designed to last for a decade or more, but as with any piece of hardware, problems can arise. Big problems may warrant full replacement of the unit, but others may simply require repair of the specific HVAC components that are malfunctioning. Here’s a quick rundown of a few potential issues:
Blowing Warm or Hot Air
If your air conditioner is blowing air with no real temperature or just slightly warm, this is often an indication of low refrigerant levels, which would need to be topped off by a professional technician. When the air is hot, however, the compressor has probably become damaged.
Odd Noises from the System
A slight rattle from inside the system most likely means that a component has become loose and needs to be tightened. If you hear a harsher sound, such as grinding or screeching, this is a big indication that any number of components could have worn out, so you definitely want to get this checked out.
The smell of burning dust or a moldy stench most likely doesn’t indicate a problem with a component. Instead, this could mean that the equipment or your ductwork needs to be cleaned. If the odor is something worse, especially if it seems electrical in nature, then shut off the system and call a professional immediately.
Low or Diminished Airflow
Most of the time, low or diminished airflow means that your filter is clogged up and needs to be either cleaned or replaced. However, if the air filter is fine, this most likely means there’s a problem with the compressor.
Turning Off for No Reason
If your equipment is turning on and off on a consistent basis without any obvious cause, this could be something as simple as a blown fuse or a failure of a variety of components. Getting it checked by a professional is the only way to be sure.
