DIBIASE HVAC

Serviced my central AC unit. Everything was done to my satisfaction. Was able to schedule my appointment quickly. Received photo of Tech that was coming out and reminder of appointment. Brian and Zach were friendly and very professional. Spoke with Chris on the phone and he gave me some very useful information about my system. Would very definitely recommend DIBIASE. The best I've run across in many years as a homeowner.

Customer stated they furnace was not working this morning, upon arrival found thermostat satisfied at temperature test furnace for over 30 mins twin system, both furnaces come on with no issues, both units come on and off based on thermostat demand, both heaters are working could not find any issues, would recommend setting thermostat at fixed setting to see if problem was about thermostat scheduling,

Performed precision heat tune up on trane gas furnace. Homeowner to replace Honeywell rp2200 air filter. Checked all electrical conections and components. Found inducer motor bearings sounding rough when starting. Also found transition piece leaking water behind inducer motor. Recommend for the price to replace these parts entire furnace should be replaced and a/c. Cleaned flame sensor and blew out condensate drain. Checked gas pressure and performed combustion test. Set up appointment with office to look at replacement.

found inducer motor running, and pressure switch proving but igniter not glowing. Had 124v going to igniter but not coming on. Found break in igniter. Had a replacement igniter on truck. Replaced white Rodgers igniter and performed combustion test. Also had a 45 degree temperature rise. Recommend due to age to start thinking about replacement of entire system, at this point homeowner is thinking more closer to spring time.

Tested temperature rise it was high, furnace was cutting off on high limit, so we then checked filter and realized it was clogged up. So we Replaced Aprilaire 413 filter. Verified new zone panel wiring. Adjusted dip switch and thermostat settings and rechecked temp rise. 50 degree split. Customer will advise us on any comfort issues.

Homeowner had the codes written down that he had recorded. Looked them up and the cof code which is constant air flow beacause of thermostat being in fan on. Then the tp5 is fan speed code. Checked over gas fitting for gas leaks, no leaks found. Ran furnace several times an could no get it to simulate the sound. Found supply plenum when you flexted it made a loud thud sound, this could have been the sound so added some bracing with s-cleat to brace supply plenum and added two pieces on return plenum to help brace duct. Also found 16x25x1 air filter pretty dirty, this does not help with the duct noise. System is working fine at time of inspection.
