Signs That Homeowners Need AC Repairs

Spring is in full force, and that means hot summers are just around the corner! With this in mind, homeowners must make sure they adequately prepare their AC systems – after all, it is probably fair to assume that most homeowners would not want to come back to a stiflingly hot house after spending time outside in the sun.

Several different signs may indicate homeowners need to seek help for AC repairs. By knowing what to look out for, homeowners can address these issues and get their units fixed to ensure properly functioning AC systems before summer hits.

Warm Air and Limited Airflow

Warm air or poor airflow may signal that homeowners need to repair their AC units. If the unit blows warm air, there may be problems with the compressor since this regulates heat exchange through coils in the home AC units and pumps refrigerant to cool the air.

Restricted airflow often results from blockages in the home ductwork, which limits circulation. Homeowners should regularly change the air filters to prevent blockages, and professional help may be necessary if the limited airflow is related to a broken motor or other structural issues.  

Leakages

Leaks in home AC units often derive from water but can also derive from the refrigerant. Water leaks are common if there are clogged / unattached drain lines or drip pan issues. The most common signs of water-related leaks include:

• Visibly dripping water
• Water damage in or around the unit
• Full drip pans that require frequent emptying
• Moldy odors

Refrigerant leaks may lead to poisoning if not addressed early enough. Common signs of refrigerant leaks include:

• Abnormally high electric bills
• Humidity indoors
• Poor cooling capacity
• Ice present on the copper lines or evaporator coils

Homeowners should seek professional help immediately if they notice any signs of potential AC unit leaks.

Abnormal Sounds

• Banging, buzzing, or rattling– these may indicate leaks, electrical problems, loose infrastructure, or broken parts
• Clicking – this may indicate issues with the thermostat or control
• Hissing – this may signal a valve leak or excess pressure on the compressor
• Humming – this may signal loose infrastructure, a malfunctioning compressor, or issues with the motor
• Squealing – this may signal issues with the motor bearings or with the fan belt, which pushes the air from the compressor to the vents   

Given the complexity of AC systems, different sounds may indicate any number of related issues, making the diagnosis process quite difficult. If homeowners notice any of these signs, they should stop using their AC system and call for help as soon as possible.
