"Next day installation, nobody else could do that. The water heater I wanted was in their inventory, nobody else had it because of COVID shortages. Best installation techs I've ever had for service. Neat, clean, attention to all details, courteous, friendly. No extra charges for extra materials, like some do. This was perfect."

"The 2 workers were on time and performed the required work to install and remove the old water heater. They seemed in a big hurry ti finish and did not ( in my opinion) check the gas lines. 2 days after the installation there were 2 gas leaks and I had to call MGE to fix."

"Great job. Aaron knew what to do and was able to complete the job in short time with the proper tools,and gave some tips on the process."

"Kip did a great job installing a high-quality water heater! He was very respectful and professional!"

"I called at 10am, the owner of the company arrived shortly after 11 and was done by noon! I could not be happier. He explained the typical cause of kitchen blockages (dying garbage disposals), and scheduled me for a replacement 4 days later. When I suggested going with a more expensive/ powerful model, he declined the opportunity to upsell. He also took time to clean up the dirty water splashes under the sink, even when I told him not to bother. Also, my dogs liked him."
