Welzig Heating and Air has AGAIN been awarded the
Angie's List Super Service Award for 2012
Welzig Heating and Air has been awarded the prestigious 2012 Angie's List Super Service Award.
This exclusive recognition is given annually to approximately 5% of service companies who achieved and maintained a superior service rating on Angie's List throughout the past year.
This prestigious award recognizes the Welzig Team's dedication to customer service and quality work and is highly esteemed by members of Angie's List.
8/13/12 from Angies List: Welzig’s office staff were quick to answer and schedule an appointment for the next available technician. We received a reminder call the day before the appointment and then again the morning of the appointment.
The morning call was to see if we would be available earlier than the scheduled time. The technician, Chris, arrived on time and was very polite and professional. He performed the maintenance, inspected the evaporator coil and gave us options as well as recommendations.
This experience was consistent with the interactions we’ve had with other Welzig service technicians.
I highly recommend Welzig to any needing heating and/or air conditioning work/service.”
