Tim was very professional and explained everything very well. I researched and found the A+ BBB rating and that they have been in business for over 25 years. I did not feel pressured or sold to, and I even cancelled another company as I found better service and professionalism with Wolff. He even gave me a sheet that compared systems in columns and broke down the cost. It helped me make my decision and not feel taken advantage of and helped me compare. In the end, I felt like I was making a more educated decision. They install tomorrow. I will update then.
Update:
They came as scheduled this morning. Three men all very nice, professional amd efficient. I am pleased with the heating system. It blows much better than what I had. It is quiet. Also, because it blows well, I think I will be able to have the heat set to lower temp (and hopefully in summer the AC set higher temp). They explained how to use my new thermostat. They used booties when in the house and then put canvas down to cover the carper foe hauling stuff in and out. They even vacuumed up afterwards.
Great experience.
