    Expert Heating and Cooling Services in New London, WI

    Every house is different once you get past the front door. Some basements are tight, others wide open, and ductwork can run in strange directions. We work on gas and electric furnaces, boilers, heat pump, and geothermal systems that need adjustments. We also check airflow and indoor air quality because dust buildup and humidity problems show up fast around here. When you call us for HVAC repair in New London, we slow down, look things over, and explain what we’re seeing.

    Signs you may need professional HVAC help:
    • Burning or dusty smells near vents
    • Cold rooms at the end of hallways
    • Thermostat settings not matching room temperatures
    • Weak airflow from certain registers
    • System fails to start at all

    Air Conditioning Services

    We usually hear about AC problems after a rough night of sleep. Our AC repair in New London often starts with checking refrigerant levels, electrical connections, and drain lines that may be backing up. Sometimes the fix is simple, sometimes the unit is past its prime. When replacement makes sense, we handle AC installation in New London and ensure the condenser pad is level and the lines are properly insulated. We also test the airflow room by room before leaving.

    • Air feels humid even while running
    • Ice forming on copper lines
    • Water dripping near the furnace base
    • Breaker tripping during startup

    Furnace Installation & Replacement

    There are times when furnace repair in New London just isn’t enough anymore. We see cracked heat exchangers, rusted burners, and control boards that fail repeatedly. When that happens, we walk you through options for furnace installation in New London without pressure. We measure gas pressure, inspect venting, and size the unit correctly so it heats evenly. A proper install avoids noisy starts and uneven warmth.

    Some benefits of a new heating unit:
    • Steadier temperatures across rooms
    • Shorter cycles during cold mornings
    • Reduced fuel usage each month
    • Fewer emergency calls during winter
    • Noticeably quieter operation indoors

Maintenance is where we catch small things early. Maintenance supports systems tied to AC installation in New London and helps prevent sudden shutdowns. We explain what we adjusted and what may need attention later, so you’re never guessing.

    • Lower strain on motors and fans

    Frequently Asked Questions

    Heating and cooling problems can feel overwhelming. We answer questions every day while standing next to the equipment, flashlight in hand.

    We suggest a spring visit for cooling and a fall visit for heating. That timing lets us catch issues before heavy usage begins.
