3 Signs Your Air Conditioner Needs to be Repaired

If you’re like most residents of O’Fallon, IL, you take your AC unit for granted until and unless something happens that makes it malfunction. Unfortunately, the majority of AC repair calls happen during heatwaves — often during the first major heatwave of the season after the unit has been out of operation for a period of months. This often results in customers having to wait because AC repair companies are dealing with backlogs of clients needing assistance.

One of the best ways to circumvent a scenario where you’ll be left to swelter during a heatwave while waiting for service is to learn to recognize common signs that your HVAC system needs attention. This will allow you to schedule an appointment with an air conditioning repair service before the unit completely breaks down. Here’s what you need to know:

Your System is Producing Warm Air

Failure to produce cool air has several possible causes. It could be that the thermostat needs to be reset or replaced, which is a relatively simple fix. On the other hand, it could signify something as serious as a refrigerant leak or an issue with the unit’s electrical system. No matter what the cause, the last thing anyone in O’Fallon, IL needs is an AC unit that blows warm air on warm, humid summer days. If the problem persists even after resetting the thermostat or making certain it hasn’t accidentally been put on the furnace setting, it’s time to call our professionals at Morrison Plumbing.

Your System Produces an Unfamiliar Odor When Turned On

Unfamiliar odors are another red flag that indicates that something is wrong with your AC unit. If the smell is musty, it could be that mold colonies have become established in the inside of the system. Although the presence of mold doesn’t necessarily mean that a mechanical issue is part of the picture, your system nonetheless should be inspected by a professional, like ours at Morrison Plumbing so the mold infestation can be properly removed.

If the odd smell is electrical, though, it could very well indicate a mechanical problem with your system. You should never run a unit that’s producing an electrical odor — doing so may result in a fire.

Your System is Making Loud Noises

Unexplained loud noises of any type should be investigated immediately. The good news is that this doesn’t necessarily mean that the unit has experienced major damage requiring costly repairs. Most of the time, loud noises are caused by something as simple as a belt or a bolt that’s come loose.

Regular AC maintenance is an essential component of preventing major issues. AC systems generally age out at around 10 years and need to be replaced, so don’t hesitate to contact us for your AC installation needs.
