Williamson Heating & Cooling - Sun Prairie's Experienced HVAC Services

First, check your thermostat settings and ensure the power switch near the furnace is on. If those are fine, it's often a sign of a faulty ignition system, flame sensor, or gas valve issue—common problems during our Wisconsin winters. For safety and to prevent further damage, it's best to call a professional. Williamson Heating & Cooling can diagnose and repair the ignition failure quickly to restore heat to your home.

In our area, poor indoor air quality often stems from accumulated dust, pollen, pet dander, and stale air trapped inside during extreme weather. Your HVAC system is central to air circulation and filtration. We help by servicing your system, installing high-efficiency air filters, recommending air purifiers or UV lights to combat allergens and microbes, and ensuring proper ventilation to introduce fresh air and reduce contaminants.

We recommend a professional HVAC tune-up twice a year—ideally in the fall for your heating system and in the spring for your cooling system. This proactive maintenance is crucial in our climate to catch minor issues, like a weakening ignition component or a dirty flame sensor, before they lead to a full furnace failure during a cold snap. Regular service ensures efficiency, safety, and reliability.
