On a hot, humid day, one of the worst things that can occur is a malfunctioning air conditioning unit. But how do you know for sure if the system needs repaired? Besides spotting a few red flags, an inspection by a professional air conditioning contractor is your best solution. Pointon Heating & Air Conditioning in Baraboo and Portage, WI, specializes in providing fast, affordable, and emergency services to get your home or business back in the cool air zone.

If you’re wondering if your HVAC unit needs repaired, look for the following signs:

• Thermostat Issues: Your air conditioning system’s thermostat may be the culprit if some rooms in the home are receiving air while others aren’t. The thermostat might need repair or replacement to resume producing consistent temperatures.
• Unusual Smells: If a musty smell is emanating from the HVAC unit or vents, mold may be present in or around the components. A pungent odor could also be a sign of burnt wiring. An experienced air conditioning contractor can pinpoint the source of any unusual smells.
• Lack of Airflow: Obstructed ductwork or a faulty compressor are among the reasons why an AC system may not be producing airflow. You can instantly tell this is the case by checking if the temperature is different in each room.
• Leaks: If you notice leaks or moisture anywhere around the HVAC unit, the problem can stem from either a refrigerant leak or a blocked drain tube. In either case, call a licensed air conditioning contractor immediately to prevent bigger problems such as mold growth.
• Weird Noises: Pay attention to the sounds when you turn your AC system on. Grinding or squealing noises could indicate broken belts or motor bearings. Squealing might be a sign lubrication is needed on some of the metal components.
