Why Your AC Isn't Working

Air conditioners are complex systems with multiple components that can fail or malfunction. Understanding what might be wrong helps you recognize problems early and avoid more extensive damage.

South Shore Mechanical can help your air conditioner overcome:

• Refrigerant leaks. Low refrigerant levels prevent your system from cooling effectively, causing it to run constantly without reaching your desired temperature while driving up energy costs.
• Frozen evaporator coils. Restricted airflow from dirty filters or blocked vents causes coils to ice over, stopping cooling entirely and potentially damaging the compressor if left unaddressed.
• Faulty compressor. The compressor pumps refrigerant through your system, and when it fails, your AC won't produce any cold air; this is often one of the more serious and costly repairs.
• Electrical issues. Failed capacitors, worn contactors, or tripped breakers prevent your system from starting or cause it to shut off unexpectedly during operation.
• Thermostat problems. Incorrect calibration, dead batteries, or wiring issues can make your system behave erratically or not respond to temperature adjustments.
• Clogged condensate drain. Water backup from blocked drains triggers safety shutoffs, leaving you without cooling until the blockage is cleared.
• Worn fan motors. Blower or condenser fan failures prevent proper air circulation, reducing cooling capacity and putting strain on other components.

While some issues, such as thermostat batteries or dirty filters, are simple fixes, others require a more thorough diagnosis and repair process. Our technicians are trained to identify root causes rather than just addressing symptoms, preventing recurring problems and unnecessary service calls.
