The home is 1,622 sq-ft and is cooled by a central 3.5ton AC unit (Split). The unit is in good working condition and the compressor was replaced about 6 years back.

Heating is by a inline gas furnace. Both the gas furnace and AC coils are ceiling mounted in the garage for easy access (pictured above). I have added a dual temp monitor so that I can view the temp differential when in operation.

Both heating and cooling are controlled by a Nest Thermostat and can be controlled and monitored on-line or where-ever you may be.
