HVAC Repair Madison WI | Call Culex Home Repair

Yes, a loud humming or screeching noise is often a sign of a failing blower motor, a common issue in Madison homes. Culex Home Repair's technicians will diagnose the exact cause—whether it's a worn bearing, a failing capacitor, or motor itself. We'll provide a clear explanation and a fair quote for the repair, using quality parts to restore quiet, efficient operation and prevent a complete system shutdown.

Our comprehensive maintenance service is your first line of defense. We thoroughly inspect your furnace's heat exchanger for cracks, check the flue for proper ventilation, and test for gas leaks—all critical steps in preventing dangerous carbon monoxide buildup. This proactive care, tailored to Wisconsin's harsh winters, ensures your system burns fuel cleanly and vents exhaust safely outside your home.

For Madison's cold winters and humid summers, we recommend high-efficiency furnaces with AFUE ratings of 95% or higher paired with a properly sized air conditioner or heat pump. We'll assess your home's layout and insulation to install a system that provides consistent comfort, reduces energy bills, and includes modern safety features to mitigate risks like carbon monoxide. We handle the entire process, including proper disposal of your old unit.
