Your Condensing Gas Furnace and Key Installation Considerations

Your Condensing Gas Furnace and Key Installation ConsiderationsReplacing your old furnace with a modern condensing gas furnace is a wise choice. Your next step, after selection but before the unit is installed in your home, is to educate yourself about installation in your Peachtree City area home.

Your Contractor

Use a contractor whose technicians are NATE certified. North American Technician Excellence (NATE) certification should assure you the technicians for your condensing gas furnace installation have been tested to the highest standards.

Talk to your contractor about previous installations of the same model as yours. Ask to see pictures of these installations, because a neat, professional job will look like the manufacturer’s brochure pictures – no odd wires, strange attachments or irregular piping.

Talk to your contractor about the calculations determining your new condensing gas furnace’s size. An oversized furnace will frequently cycle on and off, wasting energy, stressing parts, and not providing even heating through your home. Too small a furnace, of course, will struggle to heat your home during cold weather.

Your Furnace

A good condensing gas furnace installation begins with a bed of concrete block or bricks elevating the furnace out of water in the event of a minor basement flood. Water damage can lead to corrosion and rust. The pad should allow the furnace to sit level or, better, to tip slightly toward the drain into which condensate will run. The hose running from your furnace to the drain must be free of sharp bends and kinks.

All pipes and tubing should be adequately supported. All electrical work should be grounded.

Two critical pipes leave your condensing gas furnace – the air intake and the exhaust. Both should angle down toward the furnace. Both should lead to the outdoors, ending side by side at the same height. Equal height means equal air pressure, preventing back draft. Fresh air is vital for your furnace (indoor air can contain corrosive volatile gases). The exhaust pipe must rise away from the furnace so condensate will drip back into the furnace, rather than pool in a pipe.
