Fully assessed no heating situation. Found system calling for heat when I arrived and running on heat pump. System is a hybrid system from 2015. ( homeowner mentioned to me the system is still under parts warranty. Went outside to check 410a refrigerant pressures they were 300/67. Switched  system to emergency heat and found inducer motor sounds terrible.  This is a 2 speed inducer motor. Our office to check part warranty on this inducer motor and provide estimate to replace motor. System is at the point would consider replacement. System is working at this time but don’t know how long.

Completed heat tune up for natural gas furnace.

Replaced 16x20x1 filter; they are using MERV 13. I recommend using MERV 8. If you use MERV 13, replace monthly
Inspected heat exchanger, burners, flue pipe, inducer assembly and hoses
Inspected hot surface ignitor and verified resistance with meter
Cleaned flame sensor and verified flame rectification circuit
Measured temperature rise and static pressure
Checked wiring, controls, electric motors and components; there are no surge protectors; left estimate for a surge protector for each of the 2 main circuits of system.
There is 18/5 wire between thermostat and furnace. The yellow conductor is not being used. I determined by testing that there must be a break in the yellow conductor somewhere which is why the green conductor is used for the Y1 contact. Therefore they do not have control of use of fan. Provided email estimate for Honeywell S1200 Elite Pro thermostat with EIM (equipment interface module) which will allow for control of fan

I have used another company for the last 30+ years and when I needed this HVAC servicing quickly was told it would be sometime in September (now July). I asked a friend who they used that was reliable and they said "Barry with DiBoise" was their preferred technician and company by far. I called got an appointment quickly. Barry was not only extremely good technically but also was excellent at explaining to me why and how the service steps would help improve the operation of my HVAC as he performed the Service. I heartily recommend DiBoise and hope you are lucky enough also to get Barry!
