We lost 2+ weeks on the HVAC project due to the holidays (short weeks) and the nasty cold spell we had at that time. Vick’s spent all of its time repairing other systems that shut down due to the extreme weather. After the weather subsided, they spent another week doing emergency installs for furnaces that had completely quit.
Even with these setbacks, the work is progressing. All head units in the Sanctuary, hallways, offices, library, nursery, bathrooms, and Sacristy have been hung and connected. Later this week, Vick's will pressurize the system to check for leaks. Once that test is completed successfully, representatives from LG will be on site to energize the system with Freon. At that time, the heat pumps can be turned on, and the gas furnaces turned off!
The wooden plenum behind the organ, which covers the VRF lines as they enter the building, is installed. The organ will now be uncovered as all dust-producing jobs are done. The remaining holes from the old registers in the Sanctuary will be covered with flush, color-matched plates.
The auxiliary electric backup heater for the Sanctuary will be installed next. This includes a 15 kW resistive heater, a blower motor sufficient for the size of the space, an air purifying system that includes a MERV filter, a carbon filter, a UV light to kill bacteria, and finally, a steam/mist humidifier. This unit will eliminate the need for the small humidifier and dehumidifier now used to help stabilize the environment for the organ. It will be on an automatically controlled thermostat/humidistat/timer system.
We plan to replace the suspended ceiling in the hallways and entry area when all HVAC systems are installed. We hope to have the heat pump phase of the project completed by mid-February.
The final phase: French drain, permeable paver courtyard, pergola, and solar canopy (27 kW), will begin in the spring after the ground thaws.
