He came to my home about 4 years ago and fixed my furnace for 150 dollars and everybody else wanted to charge me for a new furnace for 10,000 dollars, that pretty much sums it up.

Gnoth and Lukowski has serviced our business for years; since back in the Gnoth and Naragon days. Scott really knows his stuff! It's nice to do work with a business where you have direct access to the owner. The service is beyond my expectation. You can trust Gnoth and Lukowski for all of your heating and cooling needs!

They were very friendly and prompt with responding. Scott came out himself to look at my furnace because they were booked for the week and so we wouldn't be cold.
