Great job!

My system went on the fritz. Called just after lunchtime, a couple hours later Barry was at my door. He found my issue quickly and fixed me right up. I really appreciated the level of professionalism and courtesy that Barry demonstrated. He explained what my issue was with language I could understand. Great job!

No heat for 80K BTU natural gas furnace. Found severely worn hot surface ignitor reading high ohms. As I took top combustion plate off hot surface ignitor broke. Replaced hot surface ignitor. Found open pressure switch error code. Set pressure switch to close at -.75”. Trial for ignition was stopping after gas valve opened because Glowfly universal hot surface ignitor does not properly align. Installed Goodman OEM hot surface ignitior. Trial for ignition did complete but cut out at various lengths of time after trial for ignition was comolete. Determined that pressure switch is randomly opening. Jumped pressure switch to be able to run furnace for combustion test. 71 ppm CO. Checked flues and draft. Draft is good as is pressure at pressure switch (-1,45” WC)

Found after investigating situation that the Oil furnace with heat pump located in closet area had several issues. 1st issue coil is only 3 inches from the plastic pan to the heat exchanger. Also found that inside supply plenum to feed main trunk is only a 6” or 7” hole cut into trunk. Entire supply plenum would need re-done. Also found sensing bulb to txv just hanging in the cabinet. Also found what looks like refrigerant oil dripping from mechanical fitting for equalizer line of txv. Told homeowner that I would discuss the details with the office and go from there.
