The position of a DOMElement is relative to their parent node in the DOM. It is recommended that the DOM Object be added to a div that also contains the canvas so that they share the same position on the page. DOMElement is useful for positioning HTML elements over top of canvas content, and for elements that you want to display outside the bounds of the canvas.
Jeff got three bids for the HVAC project, ranging from $3,500 to trade the old HVAC unit for a comparable model to $12,000 for a state-of-the-art system. (These price estimates are from the time of installation in 2005.)
HVAC System Average Costs. 1  For a 1,000 square foot home, the cost of an HVAC system is $6,000 to $12,000, including a new furnace, air conditioning unit, and ductwork. For larger homes and more complex setups, however, the price could be significantly higher. For central air-conditioning, you'll pay $3,000 to $5,000 and up for a 2,000 square foot home.
