HVAC Repair Plymouth MA | Call Jkm Mechanical

Short cycling is often caused by an oversized unit, a dirty air filter, or a faulty thermostat or flame sensor—common issues in our area that strain your system and spike bills. At JKM Mechanical, our Plymouth-based technicians perform a thorough diagnostic to pinpoint the exact cause. We then provide a precise repair or adjustment, such as cleaning components, recalibrating your thermostat, or advising on proper system sizing, to restore smooth, efficient operation and protect your equipment.

Signs like reduced cooling, hissing sounds, or ice on the coils indicate a potential leak, which is inefficient and harmful to the environment. Don't just add refrigerant—the leak must be found and sealed. JKM Mechanical's experts use advanced leak detection tools to locate the source accurately. We then perform an EPA-compliant repair and recharge your system with the correct refrigerant type and charge, ensuring optimal cooling efficiency and preventing further damage common in our coastal climate.

Prevention starts with professional maintenance. We recommend biannual tune-ups—once before heating season and once before cooling season. Our preventative maintenance includes checking refrigerant levels, cleaning coils and sensors, testing safety controls, and ensuring proper airflow. This proactive service, tailored to local conditions, can catch small issues before they become major repairs, improve efficiency, and extend the life of your system, saving you money and hassle long-term.
