They installed a new tankless water heater for the same price as a standard water heater, taking into account the government credits. They worked quickly, did an excellent job, and were highly professional in all regards.

The customer service was good, they arrived on time, and the pricing was great. Jacob, the technician, was a pleasant person and knew what he was doing.

Luis provided an excellent service. We had a malfunctioning water heater that needed replacement. He thoughtfully presented ideas we hadn't considered and carefully explained the available options. He spent several hours taking measurements. He is a knowledgeable professional, and we are very satisfied. The installation team will arrive tomorrow.

Both Louis and Andrew came to address our issues today. One handled a plumbing problem with our bathtub, while the other addressed an electrical issue with our bathroom vent. They were highly professional and friendly. I would certainly recommend this company. We've had three different technicians visit us in the past week or so, and the company has communicated well and seems to offer fair pricing. I appreciate that the diagnostic fee can be applied towards the cost of the work.

Monkeywrench is the number one choice, with a skilled, efficient, and friendly staff. Andy came to perform an AC maintenance check; he was highly professional, thoroughly tested all areas, and also advised us of potential issues as the system ages. I would strongly recommend this company, as I have also used them for my plumbing needs.
