From Our Website

We've gathered information on a variety of makes and models, including Lennox, Rheem, Carrier, Bryant, Goodman, and Amana.

My name is Joseph R. Lewis. I am an HVAC repair technician specializing in furnace repair. And also, I'm a writer and an author of a dozen books for kids and teenagers, which I wrote for my grandchildren. You may be surprised by this "technician and children's writer" combination. For me, it has been a perfectly natural duo, though! Since I was a boy, there were two things I loved most in my life (after chocolate cakes, of course): listening to the stories my mom read to me and working with my dad in his workshop (he was a car mechanic).
