We recently bought a house with a bad Oil furnace. We didn't really have the money to switch over to a propane system, but the HVAC class came out and installed a new propane furnace at cost, which helped them with learning and training as well as helped us save some much needed money!! The instructors and guys were FANTASTIC!! They did an awesome, complicated job in 2 days and we couldn't have been happier!! Thank you to Dan, Jim and all the guys for everything!! I would HIGHLY reccomend them!!
