Wayne was my repairman and was prompt in calling to schedule my furnace service, which ended up being the same day without an emergency or OT fee. He arrived promptly as well and was efficient, friendly, and fixed my furnace issue quickly. They were very reasonably priced. I would recommend this company to anyone in NWI.

Replaced our old furnace, air conditioner and thermostat. Arrived on time, removed the old equipment, installed the new and left the work area neater than when they arrived. All of this in just a few hours. Great service. Highly recommend.
