1. Visual Inspection: Commercial Air Conditioning Repair Near Me Ac Repair Company Near Me Local Ac Repair Near Me Heating Cooling Repair

• Check the Air Filter: Remove the air filter and inspect it for dirt and debris. A clogged filter restricts airflow and reduces cooling efficiency. Replace the filter if it’s dirty.
• Inspect the Condenser Unit: Check the outdoor condenser unit for debris, such as leaves, grass, and dirt. Clean the unit with a garden hose, being careful not to damage the fins.
• Examine the Evaporator Coil: Inspect the evaporator coil (usually located inside the air handler) for ice buildup. If ice is present, it could indicate a refrigerant leak or airflow problem.
• Look for Leaks: Check for signs of refrigerant leaks, such as oily residue on the refrigerant lines or fittings.
• Inspect Ductwork: Check for any visible leaks or damage to the ductwork.

2. Electrical Checks: Commercial Aircon Servicing Air Conditioning Repair Companies Near Me Ac Repair And Installation Near Me Emergency Hvac Service Near Me

• Test the Capacitor: Use a multimeter to test the capacitor. A faulty capacitor can prevent the unit from starting or cause it to shut off prematurely.
• Check the Blower Motor: Use a multimeter to check the blower motor for continuity. A faulty blower motor can cause weak or no airflow.
• Inspect Wiring: Check all electrical connections for loose or corroded wires.

3. Refrigerant Pressure Testing: Commercial Air Conditioning Servicing Near Ac Service 24 Hour Ac Service Near Me Air Conditioner Repair Man
