Best Flame Sensor Repair in Madison WI

As a renter at an apt complex whenever there seems to be a furnace or water heater issue my landlord always calls Cardinal.  Cardinal Heating has always been prompt in coming out to address the issues and the workmen are always friendly and are great at their jobs and clean up after themselves before they are ready to leave after the job is completed.  I know If i ever own my own house i will call these guys out for heating and cooling issues

After convincing us to switch our service to this summer, with the promise that any call, 24/7/365 would all receive the same rate, they came last week to fix a furnace mid-week. Clearly, they didn't fix it, because we have returned from our weekend away and the house is freezing. I called the tech and the rate is more than double. That is the opposite of everything they have promised. I'm extremely disappointed in this company.
