Certified HVAC Services in Staten Island, NY 10304 - DeGroat Air

Yes, frozen AC lines are very common here, often due to dirty filters, low refrigerant, or airflow problems. First, turn your system off to let the ice melt completely. Then, check and replace your air filter if it's dirty. If the problem persists, call us. We'll diagnose the root cause—like a refrigerant leak or failing component—and fix it to prevent further damage and restore efficient cooling.

Signs of a refrigerant leak include your AC blowing warm air, hissing sounds, ice on the coils, and higher energy bills. It's a serious issue because low refrigerant makes your system work harder, increasing wear and tear and energy costs. It can also freeze and damage internal components. As licensed professionals, we use specialized tools to locate and seal the leak, then recharge your system with the correct amount of refrigerant to restore performance and efficiency.

Preventive maintenance is key. We recommend a professional tune-up twice a year—in spring for your AC and fall for your heater. This includes cleaning coils, checking refrigerant levels, inspecting for leaks, ensuring proper airflow, and calibrating your thermostat. For homeowners, regularly changing your air filter (every 1-3 months) is the single most important task to prevent frozen coils and system strain. Our maintenance plans are designed specifically for our local climate to keep your system running smoothly year-round.
