The maintenance on your Weil-McLain Gold series oil fired boiler went great. The relief valve needs to be replaced due to a small dribble. The expansion tank is still good! I noticed that the humidifier on the central air portion of your system does not work. I recommend replacing it due to the current humidifiers’s age and condition. I attached an estimate to replace that with the same model. I also attached an estimate to replace the master bedroom shower valve. Thank you!

Installation of a three-zone mini-split system to provide heating and cooling for the main living area, master bedroom, and spare bedroom. Indoor heads are strategically placed to help create proper airflow. A form of electric backup heat may need to be introduced into the master bathroom for frigid temperature days. Existing oil tank and heating system will be removed. Heating system removed only - ducting and venting for system will be responsibility of client to remove.

I let some pressure out of the expansion tank and the vibrating noise disappeared. I’d recommend installing a pressure reducing valve on your water main into your home. Your current water pressure is 68-70psi. State water heaters recommends 60psi. I think that adding the PRV would eliminate the noise further.

Replaced the outlet dip tube nipple on the State hybrid HeatPump water heater with a brass nipple as it is an OEM part I do not stock on my van. The threads on the original nipple had been corroded away which was the cause of the leak. I cleaned up the water on the floor. I’d recommend leaving the door open until everything is dry. I will send a price to install the OEM replacement part.
