Prompt Service!

Dibiase has given us excellent service and great advice. I initially called them after another company installed a new air conditioner that left us with so much moisture and condensation, in our basement, that we had to replace the dry wall in the ceilings. On each occasion Joe or Chris have gotten back to me immediately and been able to give me an appointment on the same day. Their advice takes into account my budget and an excellent knowledge base.

Performed Quality Assurance inspection on Amana Heat Pump/Air Handler. Reviewed installation with tenant. Tested system in Heat Pump and Emergency Heat modes. Measured Temperature splits and Static Pressure. Reviewed air flow blower speed and all settings on thermostat. Poured water through drain line and tested EZ Trap safety. Replaced the 16x20x1 Air Filter with a filter that was onsite. Recommended to tenant that the Air Filter be checked every 1-2 months and changed as necessary. Filter should be checked in June and changed if needed.

Performed QA on Amana Heat Pump system. Reviewed installation with homeowner. Spoke with her about her concerns for the Upstairs and First Floor areas. After testing system and increasing blower circulate to 60% Speed recommended that she sees how the system operates in the AC season before closing and adjusting dampers. Explained the system characteristics and that we modified ductwork and added a return vent which will affect how the new system operates. Let her know that after the system has been running in full season we will come back in the summer for the Six Month inspection and we will see how the system has been performing and if anything needs to be adjusted then. Completed checklist form in system. This install passed the QA Inspection. 1 yellow mark for wiring: found loose wires at board terminal in AHU and also cleaned up wiring at the thermostat. Installation looked very nice. No additional follow up needed.

Compressor of 2.5 Ton Air temp heat pump shorted to ground. Megaohmeter confirms windings are shorted to ground. Emailed estimate for compressor replacement (repair). There is one return on second floor but it is not connected to return trunk. We need to assess ductwork add return as appropriate. There are supply trunk dampers on two of the supply branch ducts. We recommend replacing equipment, adding return(s), and installing smart thermostat with room sensors. Comfort consultant appointment scheduled for 12-2. Heat pump is down until compressor replacement or full system replacement occurs.

2/17/22 No heat call for Heat Pump system unit #2B. Found mechanically failed PSC blower motor. 1.5 Ton Heat Pump with 5KW strip heater. See notes for dimensions/details. Building manager wants us to think through best location for Outdoor equipment I.e. if there is a better location for outdoor equipment. All of the equipment in this building will need to be replaced in near future. Sales apply. schedule for tomorrow 10AM at this location.

Heat Tune Up for 140KBTU natural gas furnace. Inspection of heat exchanger, burners and ignitor: Good. Cleaned flame sensor; verified flame sense/rectification circuit. Replaced 16x25x1 filter. Checked gas pressure. Checked all controls, wiring, electric motors and components. Verified thermostat operation. Measured temperature rise and static pressure. Combustion/draft test: Good Homeowner renewed plan membership. Furnace is operating well at the time of this maintenance.

Performed Precision AC Tune Up on Trane Gas Furnace/Heat Pump system. Replaced 16x25x1 Air Filter. Cleaned AC Drain Line and EZ Trap. Cleaned Condensation Pump and filled to ensure it was pumping out properly. Inspected electrical components on system. On outdoor unit found the Dual Capacitor was testing below rating. Also found Contactor was very worn and had Arcing present. Installed a new 45/5 Mfd Dual Capacitor and a new Single Pole 24V Coil Contactor for unit. Complete all wiring and put system into operation. Measured refrigerant charge with system in cooling mode. Homeowner had noted on previous visit that the Heat Pump was not working. Turned system to Heat Mode and measured Refrigerant charge and air temperatures in Heat Pump mode. Heat Pump appears to be running with no issues. System is a Natural Gas Furnace as the Emergency Heat with a Heat Pump as the Primary Heat. Explained how system operates and due to system being natural gas, would recommend keeping unit running in Em

Performed Quality Assurance Inspection on system. Spoke with contractor about issue with outdoor unit leveling. Unit was level, but due to the ground behind the building slopping dramatically their is a considerable amount of run-off present. Leveled the outdoor unit and dug further down into the ground. Laid more stone down and built up stone around outdoor unit pad. Also built a makeshift runoff ditch in an attempt to divert the water flow past the outdoor unit. Spoke with contractor about filling in the entire ground behind the building, and/or creating a more natural run-off. While onsite attempted to connect Honeywell Wifi Controller to indoor unit. The system was not responding to the controller. Moved controller to multiple locations to ensure it had a clear path to the unit. Called Resideo Tech Support and they said this Indoor Unit is not compatible with the Controller. Reconnected Daikin Remote control to unit and tested. Will follow up with John Borden about other options. N

Installed new mini split system in newly converted yoga studio. Mounted head on wall close to the ceiling and centered in the shed. Ran our communication wire and line set and drain to indoor head and connected it all together. Ran the other side to the out door unit and ran it partially through line hide. Set outdoor unit on stones and leveled it out. Connectrd everything to the out door unit and did a pressure test with nitro, then vacuum down to 164 MG. Tested out and went over install with customer.
