Ignoring air conditioning issues, no matter how small,  can lead to bigger and more expensive problems down the line. Strange sounds or weak airflow, can be early warning signs of larger problems. Neglecting these signs can cause your AC unit to break down completely, which can be a costly repair or even require a full replacement. It’s important to address AC issues as soon as possible to prevent further damage and save yourself money in the long run.

Strange Smells

However, smelling mold, a musty smell, or smelling a burning odor is never normal. Moldy smells tend to indicate that there is bacterial growth within your air conditioning system while burning can be a sign of an electrical problem. Turn off your air conditioner if you smell something odd and don’t use it again until the issues have been addressed by an HVAC technician. 

Loud Noises

It’s normal for your AC system to make a humming noise that’s low while it’s running, or even a humming noise while it’s thawing itself. However, loud noises that resemble a clanking sound are not normal and could indicate loose or broken parts within your unit. 

Inconsistent Cooling

Damaged ducts, drafty windows, and clogged air filters are common causes of hot and cold spots around your home. Try changing your air filter to see if that helps improve airflow coming from your vents. If it doesn’t, a technician will be able to troubleshoot the issue further. 

Blowing Out Hot Air

Your air conditioning is supposed to blow out cool air.  If you notice your unit is blowing out hot air instead,  check your thermostat to make sure it’s in “cool” mode. If it is in the proper mode and blows hot air, it’s often a sign that your AC unit is in need of refrigerant.

Short Cycling

If you notice your AC unit constantly shuts on and off, this is known as short cycling. Short cycling can be caused by anything from clogged filters, to an improperly fitted unit, or even indicate the unit is at the end of its life cycle. Short cycling not only makes your home uncomfortable, but it can cause high energy bills and extensive damage to your system if it is ignored for too long. 

Rising Energy Costs

Does it seem like your air conditioner is constantly running? This is a sign that there is something wrong with your system and you will notice when you get your monthly energy bill. Talk to an HVAC professional if you notice that your air conditioner is running constantly or if you notice sudden spikes in your cooling bills. 

Before you start counting your pennies to pay for a new air conditioning unit, there’s a good chance that an affordable repair will solve your problem. Even issues like no cool air in your home can have simple solutions. However, there will come a time when your air conditioner will stop working, and upgrading your unit will be the best solution for your home comfort needs.

There are several signs that indicate it may be time to replace your air conditioner. If your AC is over 10-15 years old and requires frequent repairs, it may be more cost-effective to invest in a new unit. Additionally, if your energy bills have significantly increased despite regular maintenance a new system will save you money on cooling costs.
