Signs When You Need to Repair Your Air Conditioner

Warm Air

The most obvious sign of an air conditioner malfunction is the temperature of the air entering your home. Check the thermostat if warm air is coming out of the vents. Make sure it's in cooling mode and set below the current indoor temperature. If the vents continue to blow warm air, the issue could be restricted airflow or a compressor problem.

If you notice that warm air is coming instead of cool, strange noises, or increased electricity bills — these could be signs of an air conditioner malfunction. To restore comfort, consider professional servicing and repair assistance.

Water Leaks

Your air conditioner uses refrigerant to cool your home, which can cause condensation. However, these substances should not accumulate in the house or leak inside. The most dangerous leak is a refrigerant leak.

Since refrigerants are toxic, any leak requires immediate attention. If you have condensation leakage, the drain line may be clogged or damaged. These are also symptoms indicating that your air conditioner needs repair and the issue must be fixed immediately.

A puddle of water or active leak near your air conditioner indicates that the cooling system is not functioning correctly. Contact HVAC specialists as soon as possible. Leaks can quickly cause serious damage to your home.

Thermostat Problems

The thermostat is the control panel for your air conditioner, managing component operations and regulating their runtime. It constantly evaluates instructions and adjusts accordingly. If your air conditioner doesn't turn on or only runs briefly, the issue may be with the thermostat.

One clear sign that your air conditioner needs repair is a faulty thermostat. You may need to replace the thermostat for the system to function properly again.

Loud Noises

An air conditioner can make various sounds, and any of them may signal the need for repair. While most noises come from the outdoor unit during operation, it's best to consult a specialist if unusual sounds occur while your AC is running.

Examples of unusual air conditioner noises: clicking from the outdoor unit, metal scraping sounds, high-frequency tones.

Bad Odor

Another obvious sign of air conditioner malfunction is unpleasant odors. If you notice strange smells and believe they are coming from your HVAC system, it's important to address the issue before it worsens. Fortunately, quick diagnostics can reveal whether your air conditioner needs cleaning and maintenance or requires more complex repairs.

UV lights can help eliminate microbial growth in your air conditioner. Cleaning the ducts will also remove odors that have built up in the system.
