Some of the signs are fairly obvious, while others are more subtle. Knowing the warning signs will help you search for professional service before the problems gets out of control.
1. No Cool Air
At some point, you may find that your air conditioning system simply isn’t doing its job. Even at full blast, the air coming from your vents just isn’t as cold as it used to be – or isn’t cold at all. This could be a sign that your system is need of serious repair. For instance, lack of cool air could mean that your system’s compressor has failed. It could also mean that you’re your system’s Freon levels are too low. When that time comes, you might have to to replace the unit.
2. Poor Air Flow
If you are noticing weak or little air flow through your AC vents, the unit’s compressor may be failing. In case your areas or rooms in your home are getting cold air while others are not, then the trouble might be with your duct work and it’s a sign that your AC system needs urgent repair.
Over time, debris can get stuck in your air conditioning vents. Not only this obstructs airflow, but it also presents a health risk to you and your family. Having your air conditioner’s ducts cleaned is a great way to restore airflow and ensure that your AC system is working well when you need it most.
3. Thermostat Problems
At times the trouble is not with the air conditioning unit, but with the thermostat itself. One way to tell if your thermostat is a problem is if one part of your house is very cold while another part remains at the same temperature.
4. Moisture Where It Shouldn’t Be
Moisture or leakage around or near your system can be an indication of problems. When you see leaks from your air conditioning system, it can mainly because of two reasons.
In the most serious cases, the leak could be refrigerant. Refrigerant leaks can cause serious health risks to you and your family and need to be repaired at once. You must call an air conditioning repair expert right away.
Water pools adjacent to your air conditioner might show that the drain tube which disposes of the air conditioner condensation is either blocked or broken. This is not as serious an issue, but should be tackled quickly to avoid less important problems like mold growth.
5. Strange Sounds
Squealing, grating, grinding sounds from your air conditioner might be a sign that you need a replacement unit. These noises imply that something is wrong inside the unit. Failure to service the unit could result in a pricey breakdown.
A squealing noise means that the belt has slipped out of place. It may also indicate that a metal component in your air conditioner requires more lubrication. A grinding sound may mean that your motor’s bearings are broken.
6. Strange Odors
Pungent or foul smells from your air conditioning vents normally means that your conditioner’s wire insulation has burned out. Musty smells generally indicates that there is mold inside your unit or ductwork which must be taken care of without delay.
