I was just blown away by the politeness of their service tech. They came out to my house to repair my furnace and the service tech showed me how to clean my filters and use my thermostat (which has alluded me since the day it was installed by another company). If the other company would have taken the time to show me, like Walberts did, I could have saved alot of money on my electric bill. I'm sold on Walberts, they know how to treat a customer right.

Extrodinary service, a live person answers there phone, you don't "hear" that often in today's automated world. Furnace Cleaners were very knowlegable. I would definitely use them again.
