WF Hann was very accommodating and responded to my call same day. No heat in the winter is stressful in and of itself but Keith, Dennis & team helped ease our worries faster than I could’ve imagined!A few days later, our furnace officially needed to be replaced (and we replaced our AC too while we were at it) and Tom and his team were phenomenal. They arrived right on the scheduled time and were very communicative throughout.
Though my furnace is still not working, I have great confidence that they will be back today as they said with the part needed to complete repairs. Thankful for a company with staff always available for service, even 3:00 on New Years Day when it is 21F degrees with 8 inches of fresh drifting snow. My Carrier system has maintained 64 degrees with just lights and my stove running in this house for 24 hours and counting.
Ian and Chris arrived promptly at 8:00am to install the new furnace. They were courteous and professional. They completed the job before the house got cold. Ian explained the Ecobee thermostat and got me going online. I am very pleased.
