Having a functional HVAC unit is vital for your family's health and comfort. That's why you should not overlook common HVAC problems. If you ignore the early tell-tale signs, you risk your AC breaking down when it's needed the most. But how can you tell that your air conditioner needs repairs soon? Here are the common signs that you should watch out for.

1. There's warm air blowing through your AC vents

If you observe that there is warm air blowing through your AC vents, it is likely a sign that your compressor has a problem. It could also be an indication that your air conditioner refrigerant level is low. There's also a possibility your ductwork is letting in air from outside and from the attic instead of from the compressor. Therefore, when you note that there's warm air blowing through the AC vents, you should reach out to a knowledgeable air conditioning repair expert. They'll troubleshoot your unit to pinpoint the root issue and fix it.

2. Strange noises from your HVAC unit

A properly functioning air conditioning unit should run quietly. So, if you suddenly note a change from the almost unnoticeable hum to an unusual noise, you may need repairs soon. A grinding or screeching noise usually signifies that your fan motor bearing is wearing out and needs replacement. 

It's also important to pay close attention to high-pitched screaming or hissing sounds. Such noise could be an indication that your system has high-pressure build-up. In such a case, the best cause of action is to shut your system and wait for a repair expert to inspect it.  Other noises that should warrant the services of an HVAC system repair expert include banging and clanging sounds from your outside unit and squealing noise from your indoor unit.

3. A strange smell when you turn on your AC

Your air conditioning unit should never smell awful. A foul or metallic smell could indicate an issue with your AC wire insulation. On the other hand, a musty odor is a sign of mold within your HVAC system. It will help if you contact an air conditioning repair expert the moment you notice any unusual smell. Your HVAC repair expert will identify the possible cause and proceed to clean the air ducts and make any necessary repairs to prevent the same problem from arising. 

If you have noticed any of the signs mentioned above, you need to start engaging with an AC repair professional. Timely HVAC repairs will ensure that you enjoy a better home climate for a long time.
