Ice buildup is a common sign of a refrigerant leak or airflow problem in our area. First, turn the system off at the thermostat to prevent further damage. Do not try to chip the ice off, as this can harm the coils. Call us for a professional diagnosis. We'll safely thaw the unit, locate the source of the issue—often a leak or a failing component—and make the necessary repairs to restore efficient cooling and prevent future ice problems.

Look for signs like reduced cooling power, hissing sounds from the outdoor unit, ice on refrigerant lines or the evaporator coil, and unexpectedly high energy bills. Refrigerant leaks are a frequent local issue that worsen over time. Our technicians use specialized electronic detectors and soap-bubble tests to pinpoint even small leaks. We then repair the leak, recharge the system to the manufacturer's exact specification, and test it to ensure optimal performance and efficiency for your home.

Preventative maintenance is key. We recommend a professional tune-up before each cooling season. Our service includes checking refrigerant levels and pressure, cleaning coils to ensure proper airflow, inspecting for wear on components that could lead to leaks, and calibrating your thermostat. This proactive approach, tailored to our local climate challenges, helps catch small issues early, improves efficiency, and extends the life of your system, saving you from inconvenient breakdowns and costly repairs.
