    Nassau County homeowners and businesses depend on reliable heating and cooling systems year-round. From sub-zero winter nights that push furnaces and boilers to their limits, to humid Long Island summers that demand peak AC performance, your HVAC system is the backbone of comfort. At Home+ Air & Heat, we provide residential service plus scoped light-commercial air-conditioning service, light-commercial rooftop HVAC repair, RTU maintenance planning, and rooftop-unit replacement planning—backed by written options before approved work begins.

    Whether you need a routine furnace tune-up before winter, a complete central AC installation, or a 24/7 emergency heating repair, our team diagnoses the system and provides written options before approved work begins. We service many common brands—call to confirm support for the model at the property—publish current financing terms on the financing page, and document any applicable workmanship warranty. Appointment windows and emergency ETAs are confirmed by phone; timing depends on technician availability, location, traffic, and weather.

    When to Call an HVAC Professional

    Recognizing these warning signs early can prevent costly breakdowns and keep your family safe.

    Uneven Temperatures

    Hot and cold spots throughout your home indicate airflow issues, ductwork problems, or an undersized system.

    Strange Noises

    Banging, squealing, or rattling from your furnace or AC signals worn bearings, loose parts, or a failing blower motor.

    Rising Energy Bills

    A sudden spike in heating or cooling costs—without usage changes—often means your system is losing efficiency.

    AC Blowing Warm Air

    Warm air from your AC could mean low refrigerant, a failed compressor, or a frozen evaporator coil.

    Frequent Cycling

    Your system turning on and off repeatedly (short cycling) stresses components and signals a thermostat or sizing issue.

    Poor Indoor Air Quality

    Excess dust, humidity, or musty smells indicate your HVAC system isn't filtering or ventilating properly.

    Transparent Pricing

    Review the included scope and price before authorizing the work.
