5 Signs Your AC Unit Is on Its Last Leg (And What to Do About It)

Increased Home Humidity

A functioning air conditioner should manage humidity levels indoors and keep your living spaces comfortable throughout the warm days. When an AC is near the end of its lifespan, it becomes inefficient and prone to damage, leading to increased humidity levels. Additionally, elevated humidity in your living and working spaces can be a result of dirty evaporator coils and leaky ductwork. The best way to eliminate uncertainty and restore comfort indoors is to schedule a professional inspection. An AC installer can accurately diagnose the problem and determine whether to repair or replace the entire system.

Vents Blowing Hot Air

If your air conditioner barely cools your indoor spaces, check the thermostat to ensure it’s on the right setting. In addition, inspect the outdoor unit for obstructions and replace dirty filters to improve air circulation and lessen the burden on your unit. If you experience hot air blowing from your vents despite your efforts, it may be time to call an HVAC company for help. Licensed technicians understand the intricacies of different systems, helping you make the right decision for your home. Although a professional AC unit replacement is costly, it saves you a lot of money down the line and keeps your home comfortable year-round.

Strange Noises

Another telltale sign your air conditioner is near the end of its lifespan is abnormal noises when running. After a successful air conditioner installation, it is normal to hear subtle vibrations. However, loud squealing or grinding usually indicates a failing condenser fan motor or blower motor, which can be repaired. If the abnormal squealing or grinding sounds become loud whirring, then you may be dealing with a faulty compressor. This requires a full AC unit replacement to prevent further deterioration and restore functionality to your home.

Odd Smells

While the reasons for unpleasant smells indoors are many, the AC may be partially responsible. If a musty odor is flowing through your air vents, it indicates mold in your system. Additionally, burning smells could signify an electrical problem that requires immediate attention. Once you notice unusual smells when the system is running, call a professional HVAC service to diagnose and resolve the problem. Even if the system is functioning as expected, ignoring foul odors can escalate into a major problem.
