Barry fixed the thermostat and carefully explained what had gone wrong with the outdoor temperature sensor.
Our Spring service was today with Brian and it was another great experience with DiBiase Heating and Cooling. I really appreciate Brian showing up just as scheduled, explaining the service, and being respectful of our home. We are now set for the summer!
Kurt was professional and thorough.
Kurt did a great job servicing the HVAC unit. No issues. ALl done very well.
Another great experience
Really know how to fix things.
I met Mike at the house to talk about some changes to our ductwork in the attic and he was great talking it through with me as we tried to figure out a better way. After some exchange of ideas we finally figured out a nice solution to get the proper airflow we need through the system but also position the ductwork in the attic so it rests as high as we could get it in the enclosure room up there and looks neat and professional. Overall it was a great brainstorming session and I also appreciated Mike’s patience with me as I asked different questions to try and figure it out. Which we did. It’s nice when two minds come together to solve a unique challenge which is what we did! Thanks Mike!
Bill was excellent . No high pressure reviewed options. Gave great educational review of what to have in a HVAC system. Switched my service agreement to his co.
Barry did an excellent job servicing our system, he was honest about pricing, respectful and a pleasure to work with.
Luis is a pro and knows his stuff...

Tested system operation. 17.5 degree temperature split. High subcooling and low superheat indicate a restricted metering device. System is operating but not at desirable efficiency. Recommend replacing system.
1st floor system thermostat was blank at arrival. Found dirty 16x25x1 Filter and blown 3A fuse. Found loose 24V conductor causing short. Reconnected 24V connections at Contactor coil.

Strongly recommend AC Heat Pump Plan membership.
Found Error Code L2 (Hi pressure cut off 3 trips) at outdoor control board. Reset both indoor and outdoor breakers and ran system in cooling. Found slightly high R410A suction pressure. Recovered refrigerant and made small TXV adjustment (clockwise at stem). Final refrigerant data: 110LO/235HI 10.5 SH; 7 SC. Final temperature split: 20F.
Replacement of indoor txv, removed refrigerant, change txv, pressure test unit, triple evacuation, and re charge unit. After new txv started unit and ran for 45 mins check performance and found an issue with evaporator coil, itâ€™s an N coil bottom portion of coil is not getting any airflow, system was installed last summer, looking at the installation manual some brackets needed to be added for proper coil location, as right now unit unit is cooling with 15 degrees delta, I will talk to manager to see what we can do for customer. Pan needs to be placed in the right position.
Installed new Amana air handler in attic. Installed new support bracket for unit. Installed new unit on leveled swing, plywood and aux drain pan. Installed unit on snow legs. Installed new Aprilaire 3310 filter. Adpated to existing return and supply plenum. Sealed all duct connections. Installed new flex duct for each supply run and installed new 16in return flex with collars. Installed new lineset and linehide. Pressure tested past 300 psi and evacuated below 500 microns. Installed new reme halo for attic system. Installed new supply plenum and reme halo for basement system. Installed new disconnect for attic unit and installed new ez trap and condensate line. Installed new wet switch and wired all safetyâ€™s. Installed new heat pump on leveled stone and pad. Installed new disconnect and whip. Tested system in heating and cooling, system working properly. Work area cleaned.
Outdoor temp was reading 59F at ComfortNet thermostat. Searched for linked wireless outdoor sensor in installer options. No wireless outdoor sensor. Found outdoor sensor is hard wired (k-type) at outdoor equipment. Checked connections. OK Sensor itself may have had dirt in between metal and jacket causing inaccurate measurement. Outdoor sensor is reading accurately now. 74F
Had to first locate outdoor unit, located outdoor unit by turning off power to indoor disconnect and checking for 24 v to r&c at roof top heat pumps. Located outdoor heat pump and found thermostat calling but unit flat on charge. Wayne wanted to just charge the unit for now to see how it works. Addded 8lbs 6 ozs of r-410a (they provided). Pressures were 256/112. System is working fine at time of service. No further work on this system at this time.
Performed cooling maintenance, checked air filter ok. Cleaned eztrap and drain. Checked voltage, amperage and electrical connections, measured capacitor values. Started air conditioner, checked refrigerant charge. Checked operation and temperature drop across coil.
Removed old air handler and out door condenser, removed old disconnect and wipe. Removed old 36 inch lentils that the outdoor unit was sitting on along with the old pan.Removed old drain pan,wet switch, disconnect the supply and return. Blew out drain line with nitrogen, flushed out line set. Installed new air handler and outdoor unit in the same spot. Installed New Stone and pan underneath the unit made sure everything was level, installed new disconnect box also seal around any holes, installed new with going to your outdoor unit.
