10 Signs Your Air Conditioner Is Failing and Needs Repair
Updated: Aug. 02, 2023
Worried your A/C unit is nearing its final rest? Here are some telltale signs your air conditioner is failing.
Blowing Warm Air
If your air conditioner is suddenly blowing warm air instead of cold, that can indicate a range of issues, including a broken compressor or a refrigerant leak.
Slow to Turn On
It shouldn’t take several minutes for your unit to kick on after your adjust your thermostat. A delayed cooling could mean it’s time to call a repair technician.
Insufficient Air Flow
Much like a unit that takes a long time to start blowing air, it’s a troubling sign if your air conditioner isn’t blowing enough cool air. If you notice a stark difference from your unit’s typical capacity, consider calling a repair specialist.
Water Leaks
Leaks are never a good sign, whether with your plumbing or your A/C unit. Small amounts could be just condensation. A large pool or discoloration could indicate a more serious issue, like a refrigerant leak.
Unusual Odors
A foul smell coming from your unit could mean lots of things, none of them good — things like mold, mildew or a burned out wire. Those issues call for immediate repair.
Frequent Repairs
This one seems obvious, but if you’re making frequent repair calls, your air conditioner probably doesn’t have a lot of life left in it. At a certain point, you’re better off buying a new unit than funding continued repairs.
High Humidity Levels
High humidity in your home can be especially frustrating if you live in a humid climate. Don’t wait to fix the issue — too much humidity can lead to mold or mildew problems.
Frequent Cycling
Another troubling sign for your air conditioning unit is if it is constantly starting and stopping. A properly functioning unit should blow steady air, then turn off once the room reaches the right temperature.
High Electricity Bills
Keep a close eye on your utility bills, especially if you rely on auto draft. A major spike might be attributed to the transition out of winter, but it also might mean your unit is not functioning properly. Check your statement from previous years to compare.
It’s Old
Even the nicest, most expensive unit won’t last forever. Your air conditioner should last 10 to 15 years, depending on the model/brand and proper maintenance. If you’re pushing that timeline, it might be time to buy a new unit soon.
