Certified HVAC Repair in Viroqua, WI 54665.0 - A & A Heating & Air Conditioning

First, check your thermostat settings and ensure the gas valve is on. If it's still not igniting, it's best to call a professional like A & A. A failure to ignite can be caused by a faulty igniter, flame sensor, or gas valve—issues that require expert diagnosis and repair for your safety and to restore heat promptly during our Wisconsin winters.

Listen for unusual screeching or grinding noises, feel for weak airflow from your vents, or notice that the system is cycling on and off frequently. These are common signs in Viroqua homes. A failing blower motor strains your entire system. We recommend calling for service right away to prevent a complete breakdown and potential damage to other components.

Scheduling an annual furnace tune-up before winter is the best defense. Our Viroqua technicians will clean critical components, check safety controls, test the ignition system, and lubricate the blower motor. This proactive maintenance catches small issues before they leave you without heat and helps your system run efficiently, saving you money on energy bills.
