2 air conditioners & 2 furnaces??

[Kickapoo Joie Juice]

Actually our A/C is only 2.5 tons (we could have used a 2 ton but decided to increase it to 2.5 tons). We build an extremely energy efficient home and the A/C is a ground source heat pump. The heater is baseboard hot water. We heat and cool to 70 degrees.

We have dampers, thermostats and valves to control where the heat or cooling goes.

In the summer it gets in the high 90s here for weeks on end. Our system is not running all the time. It cycles on and off.

Over insulation in the walls and roof and high end windows really make a big difference.

Honey, I'm jealous, that's one schweet house you must have!
