What Our Customers Are
Saying

We’re very happy we called Koch & White for a furnace estimate! Jeremy S. was so thorough when assessing and explaining our replacement options.

I heard an ad for Koch & White on W4 Country one morning. I called them and someone was here that afternoon! Amazing service! A part needed to be ordered but in less than a week it was installed. I highly recommend Koch & White. They are my new go to company for heating/cooling/generator service.

Jan G.

From scheduling, and constant communication, all the way to the tech and their quality work, we were very happy with the experience. Highly recommend.
