L & O Mechanical Contractors | Experienced HVAC Repair in Rochester, NY

Common signs include reduced cooling, ice on the refrigerant lines, and a hissing sound. For Rochester homeowners, these leaks are not just an efficiency issue—they can lead to costly compressor failure. Our technicians use electronic leak detectors to pinpoint the exact source. We then perform a permanent, EPA-compliant repair and recharge the system with the correct refrigerant, ensuring it runs efficiently through our hot summers and is ready for the next season.

The best prevention is annual professional maintenance. We perform a comprehensive safety check that includes inspecting the heat exchanger for cracks, testing for CO in the flue gases, and ensuring proper ventilation—all critical in our colder months when furnaces run constantly. We also recommend and can install UL-listed carbon monoxide detectors on every level of your home. This proactive approach is key to protecting your family from this silent, odorless danger common in older Rochester homes.

Yes, warm air is a primary symptom of a refrigerant leak. While not always an immediate safety hazard like a gas leak, it is an operational emergency for your AC. Running a system low on refrigerant causes the compressor to overwork, which can lead to a complete and very expensive breakdown. For Rochester residents facing a heat wave, this means losing your cooling. We offer prompt diagnostic and repair services to address leaks quickly, restore your comfort, and prevent further damage to your unit.
