Arrived onsite for maintenance for one gas fired boiler. Requested the customer turn on the thermostats up to heat and confirm operation of the boiler and each zone valve. Turned the boiler m and cleaned all burners. Performed a visual inspection of all electrical and inspected all external water components such as the exp tank, fill valve, backflow preventer and the circulator pump. Observed noise from gas valve coil; may be reaching end of functionality but operating now. Also observed noise from Aquastat coil but went away. System heating as it should. Customer had issue with thermostat. Had difficulty setting time and had a flashing clock constantly.. Looking at thermostat and found it was the schedule function that flashing. Set the correct time and recommend using the hold function for that thermostat.
Upon arrival turned Unit on Heating to ensure it's normal functionality, and it was okay. Turned off the power to the unit and the gas to operate on the unit safely. Remove the gas valve screws to check the pressure of gas on the gas valve from the intake and the manifold side. Inserted temperature probes and static pressure probes. Took the pressures of the unit and everything of the unit was fine. Remove the flame Rod Center and cleaned it thoroughly and placed it back where it belongs. Check for the appropriate voltage on the power coming inside to the unit, everything was fine. Check the voltage between the power of the board and transformer, everything was fine. I have to removing all of the troubleshooting and maintenance equipment off of the unit insured proper functionality of the unit by turning it back on, unit ran fine.
Arrived onsite for issues with AC system. Customer explained it is constantly switching on and off. Performed Diagnostic.
Arrived on site for maintenance. Customer led me to a thermostat and the air handlers one being a mini split and the other being a regular air handler in the Attic. Remove removed the filters of the mini split and wash it down with a hose. Inserted the filter back into the unit the unit temperature split was 30°. Notified the customer that the mini split has a big amount of bacterial growth inside the blower. Went to the attic for the air handler that controls the first floors temperature. Look at the evaporator coil, metering device inside is a piston, everything look clean. Inserted a condensation pan pill inside the pan of the air handler. Customers stated that a while ago their air handler had an issue where it would flood but another company took care of that prior to this. Change the filter of the air handler that is in the hallway inside a register. Went outside to the condenser and pulled the disconnect of the condenser to thoroughly maintenance it.

Arrived onsite for no cooling. Checked refrigerant levels and they were zero. System flat out of r410a. Customer agreed to nitrogen leak test. Added nitrogen to refrigerant lines and found significant leak from what appears to be the outside coil. However this is a slight chance the leak is coming from the compressor refrigerant lines which is repairable. Will come back during daylight to observe inside the condenser to determine if leak is repairable. If not, customer will need a replacement condenser.
