The Grenz folks came, carefully looked at the unit, and said, "If it were my furnace, I wouldn't do anything. It is running the way it's supposed to." This second opinion cost me something, naturally, but it also saved me between $5,500 and $19,500 (two quotes from the other two companies). Jim seems like a straight shooter. I'd recommend you give these folks a try.

He also took the time to discuss with me of something that needed to be done in the future regarding our unit. Omer was extremely trustworthy and honest! Also the price was extremely reasonable!!!

Kyle and Gregg Heating are honest, fair and full of Integrity.
