• Refrigerant Lines: These copper tubes connect the outdoor and indoor units and carry the refrigerant, which absorbs and releases heat.
• Thermostat: This device controls the temperature of your home by signaling the AC unit to turn on or off.
• Ductwork: This system of ducts distributes cooled air throughout your home.

   • Check the Circuit Breaker:
     • Go to your electrical panel and check the circuit breaker for the AC unit. If it has tripped, reset it.
     • If the breaker trips repeatedly, there may be a more serious electrical problem, and you should call a qualified technician.
   • Check the Power Switch:
     • Many AC units have a power switch located near the outdoor unit. Make sure it is turned on.
   • Inspect the Outdoor Unit:
     • Look for any obvious signs of damage, such as a blown fuse or a disconnected wire.

2. AC Blowing Warm Air: Commercial Air Conditioner Repair Ac Repair Company Near Me 24 Hour Air Conditioning Service Near Me Same Day Air Conditioning Service

   • Check the Air Filter:
     • A dirty air filter restricts airflow and can cause the AC to blow warm air. Replace the filter regularly (typically every 1-3 months).
   • Check the Condenser Coil:
     • The condenser coil is located in the outdoor unit and can become clogged with dirt, leaves, and debris. Clean the coil with a coil cleaner and a garden hose.
     • Make sure there is adequate airflow around the outdoor unit. Trim any bushes or plants that are blocking the airflow.
   • Check the Blower Fan:
     • Make sure the blower fan in the indoor unit is running. If it’s not, check the motor and capacitor (see below).
   • Refrigerant Leak:
     • If the refrigerant level is low, the AC will not cool properly. This is a complex issue that requires the expertise of a qualified HVAC technician.

3. AC Not Cooling Enough: Commercial Ac Companies Air Conditioning Repair Companies Near Me Commercial Ac Service Near Me Air Conditioning Service Companies Near Me

   • Check the Air Filter:
     • As mentioned above, a dirty air filter restricts airflow and reduces cooling efficiency.
   • Check the Ductwork:
     • Inspect the ductwork for leaks or blockages. Seal any leaks with duct tape or mastic sealant.
   • Check the Refrigerant Level:
     • Low refrigerant can cause insufficient cooling. This is a job for a professional.
   • Check for Frozen Evaporator Coil:
     • If the evaporator coil is frozen, it will reduce cooling. This can be caused by restricted airflow, low refrigerant, or a dirty filter. Turn off the AC and allow the coil to thaw. Then, check the filter and airflow. If the problem persists, call a technician.

   • Check the Drain Pan:
     • The drain pan collects condensation. If it’s cracked or damaged, it can leak.
