Is Your AC Unit Showing Signs of Trouble?

Ignoring early warning signs from your air conditioning system can often lead to more extensive and costly repairs down the line. Recognizing these indicators can help you act quickly and prevent further damage. If you notice any of the following issues, it's time to call in the professionals at Stewart Heating Plumbing Air Conditioning.

Your AC Is Not Cooling or Blowing Warm Air

• Symptoms: Air coming from vents is not cold, thermostat setting is ignored, noticeable temperature increase indoors.
• Possible Causes: This could indicate a low refrigerant charge due to a leak, a malfunctioning compressor, a clogged air filter, or issues with the condenser unit.
• How We Diagnose & Fix: Our technicians perform comprehensive diagnostics, checking refrigerant levels, inspecting coils for ice buildup or blockages, testing the compressor, and evaluating airflow to pinpoint the exact cause of the cooling failure. Repairs can range from refrigerant recharge and leak repair to compressor repair or replacement.

Strange Noises Coming From Your AC Unit

• Symptoms: Grinding, squealing, banging, hissing, or buzzing sounds originating from either the indoor or outdoor unit.
• Possible Causes: Squealing often indicates a bad fan motor bearing or belt. Grinding could suggest a failing motor. Hissing might point to a refrigerant leak. Banging could mean a loose or broken part.
• How We Diagnose & Fix: We meticulously inspect all moving parts, including fan motors, blower wheels, and compressor components. Our team identifies worn bearings, loose fan blades, or debris obstructing the unit, providing precise fan motor repair or replacement, or addressing other mechanical failures.

Water or Refrigerant Leaks Around Your AC Unit

• Symptoms: Puddles of water around the indoor unit, wet spots on the ceiling or walls near the unit, or a visible residue or ice on refrigerant lines.
• Possible Causes: Water leaks typically result from a clogged condensate drain line, a cracked drain pan, or a frozen evaporator coil. Refrigerant leaks are more serious, indicating a breach in the refrigerant lines.
• How We Diagnose & Fix: We use specialized tools to detect refrigerant leaks, repair damaged lines, and recharge the system. For water issues, we clear clogged drain lines, repair or replace damaged pans, and address any underlying issues causing excessive condensation or coil freezing.

Your AC Is Short Cycling or Running Constantly

• Symptoms: The AC unit runs for very short periods, turns off, and then turns on again quickly; or it never seems to shut off, leading to high energy bills.
• Possible Causes: Short cycling can be due to an oversized unit, a dirty air filter, low refrigerant, or an electrical issue. Constant running might stem from a thermostat malfunction, a dirty coil, or insufficient insulation.
• How We Diagnose & Fix: Our technicians assess the system's size relative to your home, clean dirty components, inspect refrigerant levels, and conduct thorough electrical diagnostics to resolve short cycling or continuous operation issues. This often involves thermostat repair or calibration, or addressing electrical component repair.

Weak Airflow From Vents

• Symptoms: Some rooms are colder than others, weak air coming from vents, or a feeling of stuffiness even when the AC is on.
• Possible Causes: This can be caused by a dirty air filter, blocked return vents, issues with the blower motor, or problems with your ductwork.
• How We Diagnose & Fix: We start by checking air filters and then move on to inspecting the blower motor for proper function. We also assess your home's ductwork for leaks, blockages, or disconnections, providing solutions ranging from blower repair to ductwork inspection and sealing.
