In 2015, the average cost to install a residential wall oven is about $161, based on 2000 quotes from Red Beacon. Installing a replacement wall oven in an established area is a straightforward process that starts as low as $116, but certain factors push the cost as high as $227.
There are multiple factors that increase the cost of wall oven installation. These factors include the amount of work needed to prepare the area, such as converting to a different fuel source or enlarging the location for a wider unit. The ability of the installer to run gas or electrical lines also affects the cost. More access to the fuel lines and closer proximity to the electrical panel or the gas supply makes the installation job easier, which makes the job less expensive.
