Air conditions seem complicated, but they’re rather simple machines. An air conditioner (AC) unit compresses cold air and then transfers it throughout your home through ducts.

Over time, AC units are prone to critical malfunctions that immediately need repair. From making loud sounds to generating warm air, every AC unit will eventually encounter a problem.

The quicker you recognize these problems, the faster you can either deal with them or contact a licensed HVAC specialist. The good news is that diagnosing key AC unit issues isn’t difficult. In this article, you’ll learn how to tell when your AC unit will need repair.

Your AC Unit is Too Loud

Of course, AC units are supposed to make noise. They are composed of a motor, compressor, coils, and other components that generate a humming noise when powered on. However, if your AC unit is making a loud, rattling sound, you may need to investigate the cause.

Usually, a loud AC unit is indicative of a motor issue. Basically, when a unit’s motor is malfunctioning, it will work harder to stay on. The issue could also point to a bad compressor or debris caught in the unit’s compressor fan. The best thing to do in such a case is to contact someone who can perform air conditioning repair in Red Oak, IA to provide better assistance.

Your AC Unit is Producing Warm Air

AC units rely on using refrigerant canisters to keep your home or business cool when you turn them on. The compressor of your unit turns the liquid in the canister into a cool gas. With that said, there could be an issue with your compressor if your unit starts to blow warm air.

Your compressor could be faulty, which means you should hire an HVAC specialist to repair the issue. Refrigerant doesn’t have to be regularly changed unless you have a leak in your system. If a leak is present, call a professional to find and repair the issue immediately.

Finally, recharge your unit with more refrigerant to add more cold air into your property.

Your AC Unit isn’t Blowing Properly

Poor air flow is another issue that can plague your AC unit. There are several reasons why this problem may persist, such as:

  • Your coils may be frozen.
  • Your AC blower fan may not be working properly.
  • Your vents or air filter may be dirty.

If you notice any of these issues, it may be best to contact a licensed HVAC specialist to open your unit and determine what the underlying problem is.

Your AC Unit isn’t Coming On

If your AC unit doesn’t come on, then you are clearly experiencing a power issue. At a very basic level, an AC should power on and make a humming noise, even if the motor or compressor isn’t working properly. If you notice this problem, contact an HVAC company immediately to diagnose the issue.
