“Fast Water Heater did an outstanding job from start to finish. Very punctual and professional. Their technician was terrific. He pointed out to me that my old unit was still under warranty and I should probably get a prorated refund on it. I took his advice and wound up getting over $400 from the manufacturer. Granted, I had to haul it back to the retailer but it was well worth it. I’d use these guys again in a heartbeat.”
