Well as a time nut I have a 5061B in standby, a Kvarz Maser in standby, as well as two rack mount OCXOs two HP5065A, an Hp 53131A, two GPS Disciplined oscillators, and a DMTD system with laptop running continuously.
I am blessed with living in Lompoc CA. Our house is aligned with the prevailing on shore wind and cracking the garage door a bit and opening the rear patio door provides free AC for most of the year! Right now outside it's 55 Deg F and a high of 74 Deg F is forecast. Not like most of the rest of the country which is suffering a heat wave! So cooling power is not a driver but all the running stuff is!
Cheers,
Corby
