In the process of leasing the 3515 space our landlord had the shop A/C's put into working condition.
The work was done on June 8, 2016 by
TD Heating <br>
33 S East River Road<br>
Des Plaines IL. 60016<br>
773-267-7727
They also provided an estimate for an annual service contract as required by our lease. The recipt for the work and the estimate can be found in the PS1 google drive under facilities/HVAC.
This makes some of what is below no longer relevant.

According to Everrett, the AC in the shop froze up sometime between mid june and late april 2014. Eric Stein noted that the switch box on the bottom of the shop AC was open in mid june. That's probably not good. Presumably, nobody read the HVAC wiki page before trying to do things with HVAC. For shame!

Service was provided by "My Guy HVAC" They were on time and professional. The only issue was the technician struggled a little with the unconventional connections in the shop system. The were working on a flat service fee so no extra cost was incurred because of his confusion.

The front room has a thermostat near the safe. This system is independently controlled by the same boiler system in the boiler room. This thermostat ALSO controls radiator pipes upstairs. Setting the thermostat high in the lounge can make the upstairs area very warm, be aware.

==== Shop ====
Around the end of December 2015 the heat in the shop stopped working. the boiler, thermostat and the circulating pump all seemed in working order. Most likely cause was determined to be an 'air lock' preventing circulation. There is a valve at the high point of the piping, it's at the heat exchanger above the kitchen just north of the door to the shop. The boiler was switched off, a hose was run from the valve to the kitchen sink and the valve was opened. Nothing happened. The gauge on the boiler showed 12 psi and it was expected that the automatic makeup water valve would open and add water to the system forcing any trapped air out. This did not happen. Water was added manually until a steady flow was draining into the kitchen sink. The air bleed valve was closed and the system was turned back on. The system was run until all four heat exchangers in the shop came on. Then the process was repeated and more air was purged. It was also noted that prior to starting the process that the expansion tank was empty although the boiler was hot. The system was left running with a boiler pressure of 18psi and the expansion tank about 1/8 full.
* It may be that the automatic make up water valve is defective or set to come on below 12 psi and it also may be that the static pressure at the valve is about 12 psi with another valve open to atmosphere.

In the boiler room the two red pumps that force hot water for radiant heat in the front room and the shop area. These pumps have three ports for oil lubrication. The two ports on either side of the pump get 3 drops of oil each, the covered port over the bearing needs one strong squirt. This needs to be done annually. This was last preformed 2015-04-01.
