7 Signs Your Air Conditioner Needs Repair

An air conditioner, also known as AC, is a piece of equipment that is designed to keep the temperature inside a building comfortable. This usually happens by moving outside air into the building and then cooling it down before returning it back. Air conditioners are found in buildings, cars, and houses.


Like all motorized equipment, your AC system can wear out and need repair or replacement. Even if your unit is not running, you should have it checked once a year for any potential problems with the system or its components. Many homeowners make the mistake of ignoring noise or other warning signs or symptoms of a failing air conditioner until it’s too late.

To determine if your AC needs repairs, there are several signs. Here are a few of them.

1) Unusual Noises

An air conditioner should run relatively quietly and you should barely be able to hear it. If your unit is constantly humming or you are hearing other unusual sounds, it could be because the bearings in your compressor are starting to wear out. If this occurs, you should contact a professional as soon as possible to fix the problem while it can still be remedied.

If your AC is making a loud noise or it’s producing too much heat and it’s causing rust or mold to grow inside, you should contact a professional for repairs. They can help you determine the specifics of your AC problem. Don’t ignore the problem because eventually, it could cause additional, more costly damage to your entire AC system.

2) Warm Air

The whole point of an air conditioning system is to remove heat from the air. If you find that your home is always warm, even after your AC has been running for hours, then it is most likely a sign that something is wrong with your unit. It could be that there is not enough refrigerant in your system. Your air conditioner might be running too hard, which can also cause this problem. Or it could be because your unit has developed a leak and the refrigerant is leaking out, flooding the inside of your AC unit.

By having a professional repair your air conditioner you’ll ensure that you’re able to keep your house cool and maintain the correct temperature.

3) Smells Bad

If your home is starting to smell bad, then it’s possible that your AC has a leak. If you notice a strange odor coming from your unit, such as burning rubber, it could be that there is too much pressure in the system and the refrigerant is being pushed out of the seals and into the tubing. Another possibility is that there is dirt and debris in your compressor. A professional will be able to tell you what’s wrong with your unit and how to fix it.

4) Freon or Water Leaks Around the Air Conditioning Unit

If your air conditioning unit is leaking Freon or water, you should stop using the system immediately and contact a professional company for repairs. The refrigerant goes through a system that has to be maintained and checked regularly. Any leak can eventually cause damage to your entire AC system which will require repairs by a professional company.

Do not use an AC unit that leaks Freon because of the damage it could cause to the rest of your air conditioning system. Freon is a chemical that could cause harm to your health if it is leaked inside your house.

Contractors are required by law to install and maintain the necessary safety devices so that refrigerant evaporates outside of your home. While Freon can’t get into the air outside, if a leak occurs, it can affect the people living in a home as well as damage other items.

5) A Weak Air current

If you notice that your air conditioner is not blowing very hard, it probably means that your unit has developed a leak. Small leaks might seem like they’re not doing very much damage, but they can cause serious harm to the rest of your AC system.

A faulty capacitor can also create a weak air conditioner because it is responsible for controlling the electricity in your system and without it, you will have weak cooling. If your air conditioning unit is not blowing as hard as you would like, then you should contact a professional to fix the problem.

6) Very Hot or Cold Areas in the House

One of the most common problems in many AC systems is that they are not able to keep up with the temperature of the entire house. In some cases, you will notice that it’s cold in one area and hot in another. If this is happening in your home, then it could be because your air conditioning system isn’t strong enough and can’t supply enough heat or cooling.

Having a professional company inspect your AC unit can help you determine if your system needs to be adjusted or if it just needs repairs.

7) Increase Utility Bills

If you’ve noticed that your utility bills have been increasing over the last few months, then it means there is probably something wrong with your AC system. It could mean that your air conditioner can’t keep up with the temperature of the whole house. It could also be because your air conditioner is starting to fail and isn’t able to cool down the area properly. You should contact a professional company to check your system and see if it needs repairs or servicing.


We cannot stress enough the importance of regular AC maintenance! Failure to address a problem with your air conditioner can lead to major repair costs, even if you don’t have a warranty. Don’t let yourself become a statistic – get your unit checked out regularly for whatever underlying issues you might be experiencing.
