Jacob, with Holley Heating & Air Conditioning Company, came out and replaced a water heater for me and the water heater is working very nicely. Jacob really impressed me with his knowledge and his friendliness. I will be requesting Jacob the next time I call Holley Heating & Air Conditioning Company to do some work for me. They have been doing a great job for us for over twelve years, I would recommend them to anyone. They have been keeping my HVAC system running smoothly for these last twelve years. I will definitely use them again.
