When relaxing in your home, your comfort revolves around the efficiency of your AC appliance. However, when your unit suddenly begins to malfunction during a hot day, it may cause discomfort and inconvenience your daily routines. Moreover, it may strain to cool your house, causing the energy bills to skyrocket. 

Since these issues may escalate into system failure, it is vital you engage an AC appliance repairer. They will examine your unit for defects and remedy them to restore your indoor comfort. Read the signs below to find out if your AC appliance is defective.

Odd Smells

When you notice unpleasant smells when you turn your unit on, it could be defective. For instance, a burning smell indicates electrical components smoldering, while a rotten egg smell points to a gas leak. Additionally, your AC will emit a musty smell when biological growth infiltrates the system's drainage.

Weak Airflow From The Vents

When there is weak airflow from the vents, you will notice insufficient air circulation to cool your house. This is due to clogged or overly restrictive filters or even debris buildup in your ducts that impede airflow to and from the unit. In addition, if the ductwork develops holes or cracks, cool air will escape into unconditioned spaces, resulting in poor airflow. Thus, it is wise to hire an AC professional to clean or replace your filters regularly and seal the ducts to prevent energy loss.

Loud Noises

Your HVAC appliance should make a relatively low sound when in operation. However, when these sounds translate into loud noises, they could indicate a malfunction. For example, you will hear rattling noises when a loose part dislodges in the blower assembly. 

Furthermore, your unit will produce a hissing sound when a duct leaks, while clicking noises indicate a defective electrical control. Since these noises point to underlying issues, it is imperative to engage a technician. They will fix the source of the noise and ensure the unit's operation is not disruptive.

Water Pooling Around The Unit

If you notice puddles of water beneath your AC unit, it could be leaking. This is due to the condensate line breaking from the pan and leaking water. Moreover, the drip pan may deteriorate and crack over time, spilling the condensate on the floor. On the other hand, if mold, fungus, and sludge clog the condensate line, water will overflow in the pipe and drain onto the floor beneath. Therefore, you should engage an AC appliance expert to clean your system's drains to prevent water damage from condensation build-up.
