I had called and spoke to Kris; he came out and gave me a estimate that was much better then the 3 others I received. The techs arrived when on schedule and the installation went perfectly and the area was efficiently cleaned, almost as if they hadn't been there. The techs then explained everything from start to finish. I would recommend Olson's to everyone. One of the best decisions I made was having them replace my furnace and air conditioning. Kudos to Kris, Barkley and John.
