Not sure if the range or…read moreinstallation is faulty but two of the five burners have no temp control and burn at highest temp. They also did not measure the underside of the range and the range they ordered was too small for the receptacle, they fabricated a fitted retainer of extremely low quality with sharp edges and gaps. Forget that it took them over a month from when contacted to arrive and then and additional two days to install. We contacted 7M four times within that month and only returned a call when at the door for installation. During the two days it took for installation they decided to leave all their tools in our kitchen and left exposed live wires in the work area. $800 for the installation, for a grand total of $1,407 after tax and a disclaimer on the bill that states: "Any expenses of andy unforeseen issues found after the initial repair or installation of the original quote will be added as additional work upon the customers approval." I feel like I've been robbed

They came out immediately and during an extremely busy time of the summer. We are also in a rural area outside the city limits, so it isn't always easy to get 'ANY COMPANIES' to come this far out. I was so pleased with the service that I had them come to my place of business, (a County Facility) to repair a/c and heating problems that I have had in our building..(It is an extremely old building). I felt very comfortable with the techs that came out and one thing I will say, they were clean, fast and explained what they were doing including the cost before they did anything.
