Thanks Heather and Larry

L&L fixed our furnace during a cold spell last Winter. They came out the next day and installed the furnace in a couple hours. It has worked great and our utility bill actually went down!

What can I say other than thank you! Phil and his team had our new furnace installed within 24hrs. The installation guys were very clean and knowledgeable. Thanks so much for keeping our family warm this winter.
