This company is a total joke. I'm not sure the installer was even certified. He made repeated phone calls to ask the person on the end of the line how to do the installation. He said he confirmed that the "gas company" was coming to do the hook up, but at the end of the day, they left me with no heat for 4 days. The A/C coil was not properly braced, or supported, and it flooded the furnace, and completely soaked the electronics. They patched a water intake line into a pipe feeding my inground sprinkler system, turned on the valve for that pipe and flooded my sprinkler system, which then froze and wrecked it.
Things they :broke, or improperly installed are still not fixed.
