Overview of the GCS16

Lennoxís discontinued GCS16 air conditioner, first introduced in 1989, is a combination packaged gas heat/dx cool unit for residential and light commercial use. It is available in sizes ranging from 2 to 5 tons for residential applications or 6 to 25 tons for commercial use. The unit can be installed on rooftops or on the side of buildings, with discharge air directed from beneath or horizontally. The GCS16 has an AFUE of up to 80 percent and a SEER of up to 12.70. The unit uses R-22 refrigerant.

Lennox manufactures cabinets from heavy gauge galvanized steel and coats them with an electrostatically bonded powder enamel paint. The internal components are accessed via removable cabinet panels. The control boxís placement and removable aluminized steel burners were designed to be serviced easily.

The GCS16ís heat exchanger is made with aluminized steel, providing resistance to corrosion and rusting. The curved, rounded shape of the heating surface was designed for improved heat transfer, and direct spark ignition improves efficiency by sparking intermittently.

The Lennox GCS16 is equipped with fan guards made with corrosion-resistant PVC coated steel wire. GCS16 models have either one or two fans, and each unitís motor is permanently lubricated and protected from overload.

Both the residential and commercial models of the GCS16 can accept various thermostat control systems. Several accessories are available, including the economizer, warm-up kit and Honeywell control products. The cabinet has a low voltage terminal strip enabling field wiring.

"Never Again!"
The unit was new when I had my house built in 2007. Compressor is locked up and full of R22. Of course, I called should have been under warranty right no my unit was built 2004 and sat on the shelf till my home builder purchased it and install. But Lennox says warranty starts on the date of unit manufacture not when consumer purchased it! I had my unit gutted and switched to 410. I'm out of pocket $3,600.00 in my subdivision the HVAC repair trucks are here more than the residents. They are dying at the same time. 2 neighbors next to me locked up compressors and massive coolant leaks, all are switching to 410. R22 is too expensive and getting hard to find!

"Piece of Junk!"
This is the ac that came with the house. The whole neighborhood has them and they are all junk. a/c repair guys love our neighborhood though. They are making a fortune off the repairs and replacements. We have two units and each year, one of them breaks, guaranteed. Dont buy a Lennox, it will cost you thousands in repair bills!

"You can blame the equipment or the guy who put it in."
Most homeowners who have a problem will blame the brand name not the cheap hack who put it in. If you have a cheap contractor install your equipment expect it to run poorly.
