11 Signs Your AC Is Going Out: What to Watch Out For


When your AC suddenly shuts down, it can seriously inconvenience your comfort. While temperature control systems should function for 15 to 20 years without issue, problems can arise that cause premature expiration. Although it may seem like a sudden shut down, signs your AC is going out usually begin long before it dies.

Knowing the symptoms of a failing AC unit helps you avoid inconvenient breakdowns. Many of these issues may only require simple repairs that professionals can perform well before your unit fails.

Call Westerville’s trusted air conditioning repair company when you notice any of the signs your AC is going out. Expert repair technicians from World Class Services can provide efficient repairs to prevent inconvenient HVAC breakdowns.

11 Signs Your AC is Going Out

Call professionals from World Class Services if you notice any of these 11 signs your AC is going out.

1. Increased Electricity or Utility Expense

Rising bills provide an early indication that your AC unit is on its last legs. When your energy bill increases, it signifies that your unit has to work harder and use more electricity to achieve the same temperature control results. 

Keep track of your bill. Increases can indicate potential breakdowns or signify minor issues. Professionals can diagnose the cause of your energy expense increase.

2. Only Humid or Warm Air Blows

Healthy air conditioning units can provide cool air at any hour of the day without issue. However, if you turn on your HVAC cooling function and notice increasing humidity levels or warm air flow, it might indicate significant decline in HVAC functioning. 

Warm air and humidity can signify issues ranging from minor problems like refrigerant leaks to major issues like an expired outdoor unit. Professionals should inspect your system to diagnose the problem.

3. Strange Sounds During Operation

Strange noises during HVAC operation can suggest various problems. From broken mechanisms to an upcoming breakdown, clanking, hissing, or sputtering while using your AC should motivate you to call professionals.

4. Thermostat Malfunctions or Unresponsiveness

Your thermostat should immediately trigger HVAC functioning and provide proper temperature control. If your thermostat fails to efficiently start up your unit or is completely unresponsive, it might signal an upcoming breakdown.

5. Limited Air Flowing from Vents

Obstructed airflow makes it harder for your system to achieve your desired temperature in a reasonable timeframe. Many issues can cause limited air flow from your vents. Ductwork issues and dirty filters can decrease the consistency of air flowing and divert cool air into home spaces like attics or roofing structures.

6. Strange Odors During Operation

Another warning sign of HVAC breakdown is strange odors during operation. Rotten or rusty smells can begin long before an AC unit reaches its last successful operation. Capitalize on this early warning sign by calling professionals to service your unit.

7. Inconsistent Cycling

Consistent and frequent cycling of your unit is essential for effective temperature regulation. While healthy units maintain a routine on and off cycle, declining HVAC systems might turn on and off sporadically. Not only does this limit effective temperature control but it could lead to a complete breakdown.

8. Frequent Breakdowns and Repairs

It’s normal for HVAC units to experience issues occasionally. However, if the frequency that you have to call technicians for repair significantly increases, it might indicate problems beyond normal standards. Consider replacing your unit if you’re getting repairs too frequently. 

9. Delayed Start

When you try to start your unit, does it have a significant delay before powering up? Delayed starting can signal issues with electrical wiring, circuit breakers, or your blower motor. Even worse, this is one of the primary signs your AC is going out.

10. AC Unit is Over 15 Years Old

The typical lifespan of an HVAC unit is 15 to 20 years of operation. If your unit is above 15 years old and becomes increasingly inconsistent, it might be reaching the end of its lifespan. At this point, you should have professionals replace your system.

11. Refrigerant or Water Leaks

Refrigerant and water leaks not only damage your HVAC unit but also your home. Leaking refrigerant can freeze your air conditioner, and leaking water can cause major water damage to your home. If you notice liquids coming from your HVAC unit, call professionals immediately.
