    24 Hour HVAC Servicein Nassau County

    Furnaces quit at 1am. AC dies the Saturday of a heat advisory. That's when most shops send you to voicemail. We keep a dispatcher and an on-call tech running out of Jericho every night of the year, so you get a straight answer about who's coming and when.

    Why Long Island Homeowners Choose Us

    A person answers

    No answering service taking a message for the morning. Our dispatcher picks up and tells you the actual ETA.

    Same diagnostic fee at 2am

    The visit fee doesn't change because it's late. Repairs are quoted flat-rate before we start, not billed by the hour.

    Trucks stocked for no-heat calls

    Igniters, thermocouples, capacitors, blower motors, transformers, refrigerant. Most calls end in one visit.

    One number for the whole house

    Boilers, furnaces, central AC, heat pumps, water heaters, oil burners — all handled by the same crew.

    Dispatched from Jericho

    Local techs who know Levitt ranches, Garden City steam systems and Syosset new construction. Not a call center out of state.

    We handle the paperwork

    If an overnight repair turns into a replacement, we pull the permits and coordinate the Nassau inspection.
