Best Energy Efficient Heating Systems in Denver CO

Called Horizon out after our furnace died on us, they were able to diagnose, repair, and get our system back up and running. They even took the time to help us understand and set up a thermostat schedule based on when we are home. Outstanding service and very knowledgeable crew!

Very, very detailed in explaining what was found, the options to fix, and continuous updates throughout the process. Bryan is a star.
