"Excellent experience during a bad situation. We discovered our well head was leaking on a Sunday afternoon. Joe, the owner, came out the same day to assess the problem and told us how to avoid burning out the water pump. Joe and his crew came out the next day. Repaired the problem, with no surprises. He took the time to explain what was wrong and what he needed to do. Very professional, courteous, and knowledgeable. Everyone at Old Faithful Pump Co is friendly and it was pleasure doing business with them. We recommend Old Faithful Pump Company to everyone."

"Harmond helped me over video link to test the components in my broken refrigerator. The testing confirmed that it was the compressor that had failed. I purchased a new refrigerator because I decided it was not worth the cost to replace the compressor."

"We installed a new sump pump and a back-up pump in our home. The whole experience from start to finish was excellent. The estimate and price was fair and the work was accomplished in a timely manner. The installer arrived on time, did a great job, tested both pumps, cleaned up the work area and left the place spotless. Can't ask for more. Tony & Joan CT."
