Had taken my vehicle here for a few years now first my Honda pilot which they replaced my motor and later a alternator. Most recently my Ford superduty for power steering and had the AC repaired. They are one of the most honest and reasonable price mechanics around. Big plus is even through they tend to be booked 10 days or do out when I drop vehicle 99% of the time it done that day the 1% was the motor replacement which they took 2 days to complete which quite fast turn around

We had our vehicle break down on our road trip. He was able to get and replace a water pump in little time and at a very reasonable price. Highly recommended.

I had a great experience here. I was told by another party I needed a new fuel pump, based on the error codes. I called Merfeld Brothers and made an appointment to get the fuel pump replaced. Turns out the fuel pump was not the issue, but the mass airflow sensor was messed up. They found the correct problem and had it taken care of quickly. The price for the diagnosis and repair was really good. I will return for future repairs.
