If you go this route, make sure and inspect them upon arrival so you can refuse delivery if there's any shipping damage. If there's a glitch with the installation, then it's up to the installer to make it right. If there's a defect in the product then it should be covered by the manufacturer's warranty - you'd have to contact them. Even if you buy locally, you'd most likely have to go through the manufacturer for warranty service although some local retailers have factory authorized service departments.

Appliance installations are pretty simple. Usually a handyman can do it. You just need to be prepared before they arrive by reading the installation guides and having everything in place before they get there.

To add to weedmeister's post - check the installation specifications to verify that the gas line or electric outlet is in the proper location for the new appliance.

We just installed a new refrigerator and I knew that the electric line had to be relocated so my installer was aware of that ahead of time.

Thanks for all the input, folks. I'm going to begin looking around for installers. Unfortunately, there is no gas line for the cooktop and I had two plumbers come out. Both quotes were extremely expensive to run a line because of our house's structure and how they would have to run it. So, induction, here we come!
