To deliver the most professional heating and cooling service available by way of an unmatched client experience, resulting in the highest levels of respect from our community and a rewarding environment for our employees to succeed.

I finally had enough. I simply could not deal with this any longer. In 2002 I finally decided to do what I should have done years before, I started my own heating and cooling company. D&L Mechanical named after myself Darren Billington and my beautiful wife Leisa was created to be the company I always wanted to work for, one with honesty, integrity and real professionalism. Running my company in Fredericksburg Virginia has been amazing. We love our customers and treat them like family. I wouldn’t give this up for anything. The problem is, I can really only service people in my general area. The distaste I have for the business practices I experienced at the other HVAC companies I worked for still bothers me. I’m disgusted by it because it still goes on to this day! I always wished for a way to help homeowners not get screwed over. There was simply nobody out there telling the truth, so I decided to do it myself. I wrote a book to help you, the homeowner, that needs work on their HVAC system or is in the market for a new system. I wrote this book to cut through all the mis-leading out there and give you the tools to make certain you have a good experience with a contractor. I’ll tell you how to make sure you select a reputable company (and no, its not Angie’s list), how to keep from getting scammed, and finally how to understand HVAC systems so you can make educated choices.
