"Needed a leaking water heater replaced. Todd was great at providing a quote for the job, and working me into his schedule for the next day. Punctual and efficient...and within an hour or so I had a new water heater with hot water! Would highly recommend for a job well done."

"Randy Lane has skilled plumbers and a well-organized office staff. The plumber arrived at the pre-arranged day & time and fixed the two sinks. The plumber looked at the corroded sections of pipe that I pointed out and stated that his opinion was that replacing those would not significantly increase water pressure in the house. I appreciate the honest opinion.

"Went very well. Installers were very courteous, knowledgeable, and everything went smoothly. They had the new gas valve that was needed to bring the connection up to current code, had the city of MInneapolis permit all completed. Both men were very personable. They were much better than the office people I talked to prior...to set up appt. But all turned out great."

"The upfront scoping of the project was excellent. Joe spent the right amount of time getting the details right so when his crew arrived to do the work, they already knew what they had to do. The pricing was competitive as well, plus they offered me an extended warranty for the water heater over and above the standard warranty."

"The hot water stopped working all of a sudden a couple of months ago. The dryer started making a clinking and sometimes a thudding noise that could be heard throughout the house.

The clinking noise in the dryer was a loose screw that was holding one of the paddles secure (thudding noise), both were easily repaired.

The hot water on the washing machine stopped several months back, turned out the switch to command hot water was dirty. The technician was able to get hot water working very quickly.

I was thinking that I would probably have to replace them both and was a little scared of getting them repaired so $200 is a more acceptable alternative."

"They arrived on time and did the work in the amount of time they said they would. Our particular installer was very professional, despite his extreme allergy to our cats. It was so bad that if I were him, I honestly may not have been able to complete the work. He trudged through, did an amazing job with quality work, despite his circumstances. We've had the system installed for ten months now with only one small issue, which the company quickly and professionally resolved it for free. I would absolutely recommend them and not hesitate for a second to call them for future needs. Having the whole house humidifier through last winter has made ALL the difference in the world and we're kicking ourselves for having waited so long."
