Luis knows his stuff and does great job.
Brian was thorough in his assessment and transparent.
Luis was very knowledgeable. Answered my questions throughly & thoughtfully. Happy to have found this company.
We've been using DiBiase for several years. They've always had competitive prices and are very professional. Brian was out today to perform a checkup. He was here almost an hour, and he appeared to actually do things. He's friendly and kept things clean.
Did a great job and professional.
Performed Six Month Inspection on First Floor Heat Pump/Propane Furnace system. Checked Air Filter and inspected Condensation Pump and filled to test operation. Put system in Heat Pump mode and measured refrigerant charge on system. Turned on Humidifier and tested operation. Adjusted the Water Flow and set Humidifier Control to 35%. Switched system to the Gas Furnace and Measured Gas Pressure and performed Combustion Analysis in both Low and High Stage Heat. Verified Settings Lockout Points on Control Board. System is operating to standards in Heat Pump and Furnace Modes.
Recently install HVAC UNIT not working, found unit locked out on high pressure fault, check low pressure and high pressure switch wiring, found low pressure switch wiring rubbing copper tubing from txv, tape wire using electrical tape and used cable tie to keep away from copper, check operation of entire system ran unit on cool regular heat and back up heat, check all settings and programming ok, check refrigerant pressures super heat and sub cooling ok delta split 18 F 72/54 performed quality assurance during visit overall installation looks good did not performed any changes or modifications regards installation. Set thermostat to cool 72 customer will set up schedule based on their needs.
Removed and replaced existing gas furnace, coil and condenser. Replaced with Amana gas furnace and coil with a heat pump outside on a brand new pad sitting on heat pump feet. Pad is leveled along with heat pump. Converted gas furnace with a LP kit. Replaced disconnect box and installed a new electrical whip from disconnect box to heat pump. Installed EZ trap thatâ€™s ran to a condensate pump and vinyl tubing ran into sewer drain. Installed media filter aprilaire 413 filter. Ran new gas pipe to connect existing gas line and all copper brazes have been pressure tested and put unit on vacuum. Ran tests on unit and ran in heat and cooling. Added charge and adjusted gas pressures.
Cleaned outdoor coil for second floor unit, after cleaning coil check operation of heat pump found system to be low on refrigerant, next step is to find where the refrigerant went, we need to add refrigerant and dye so we can find out where is the refrigerant leaking, manufacture does it cover the cost of refrigerant and dye, customer approved adding refrigerant and dye, we will check for leaks next time we came back for tune up, also check older first floor unit, found unit to be slightly low on refrigerant r22, it is not low to the point where is not cooling, but system is loosing capacity and efficiency, would recommended system replacement we will provided an estimate to replace system
Maintenance Plan 2021-2022 AC Tune ups for 2 AC Systems. Compketed AC Tune Up forms for each system. Amana +attic system) outdoor coil is dirty and I undercharged. Provided estimate to clean OD coil and assess/address charge. Basement unit is undercharged. Provided estimate to charge system. No other issues at this time.
Checked no heat on second floor furnace, found power off to furnace. Turned power on, the blower came on but no heat. Found roll out switch tripped. Reset roll out switch. Started propane furnace, after burners light I see the top chamber of the heat exchanger have flame roll out. Checked venting ok. Blew out condensate trap. Heat exchanger is restricted and must be replaced. Recommend replacing furnace. Furnace needs a heat exchanger furnace is installed in attic between truss and has no room to be removed. Recommend replacing furnace. Will have heat until roll out switch trips again
Perform gas boiler check up check electrical high and check water piping clean heat exchanger burners checked gas pressure check water pressure and temperature test limit ok performed combustion test on boiler ok would recommend having chimney check by chimney professional cycle boiler ok
Performed cooling maintenance, replaced air filters. Cleaned condensate drains. Checked voltage, amperage and electrical connections, measured capacitor values. Started air conditioners, checked refrigerant charge and temperature drop across coils.
Performed Quality Assurance on American Standard AC unit. Only inspected the outdoor unit because no one was home at the time. Corrected any issues that were found. Completed appropriate fields on the Checklist Form. I would not pass this installation. It looked nice from farther away, but the details of it were missing. For an AC and Coil install the minor details I listed on the checklist should have been completed.
Reclaimed and removed old ac and coil. Installed a new American standard coil on top of existing furnace. Adapted all supply ducting as needed , taped and sealed all duct. Installed a new condensate drain with a ez trap wired in.installed a new condensate pump with new vinyl tubing ran outside. Installed a new American standard ac unit on a new plastic pad . New disconnect box and electrical wiring to unit. Brazed all joints and leak checked with nitro and bubbles. Tested unit and it is working great.
Checked no cooling complaint and coil icing up. Checked air filter ok, checked refrigerant charge, found low on charge. Recommend replacing air conditioner vs repairs due to age and condition.
Checked condensate leak, found new furnaces and air conditioners getting installed.
Performed heating maintenance on gas furnace and heat pump, cleaned burners and flame sensor. Inspected heat exchanger, see rust on heat exchanger, and burners. Checked voltage, amperage and electrical connections, measured capacitor values. Started gas furnace, measured fuel pressures, and tested limit and safety switches. Performed combustion test. Serviced humidifier, cleaned and replaced water panel. Started heat pump, tested defrost cycle, measured btu output. Checked operation and temperature rise across coil.
Service call that both the First Floor and Second Floor Systems were not operating. The First Floor Thermostat was calling for Cooling but the Indoor Temperature was at 79 Degrees. The system was not running due to the Safety Interlock Switch on the Condensation Pump being tripped which shut power off to the unit. Found the Vinyl Tubing for the Pump was clogged. Cleared the Vinyl Tubing and System began operating again. Filled Pump multiple times and tested operation. Measured Refrigerant Charge and found System to be slightly low on Charge. System is still Cooling with a 18-19 Degree Temperature Split but the Superheat Levels are higher than normal indicating that the system is below the recommended refrigerant level. System was calling for a 19 Degree Superheat and was running at a 40 Degree Superheat. Second Floor System was running but was not cooling. Measured Refrigerant Charge on system. The Compressor is running but is failing and is not pumping Refrigerant Through the system
Performed Precision AC Tune Up on the First Floor and Second Floor System. Replaced the Air Filter on the Second Floor System. Cleaned EZ Traps on both Systems and Condensation Pump. Inspected Electrical Components on Indoor and Outdoor Units. Measured Refrigerant Charge on both Systems. The First Floor System Refrigerant Levels were slightly off. Superheat Levels were higher at 26 Degrees and the Indoor Coil Temperature was around 33-34 Degrees. This indicates that the system is low on Refrigerant. Also found the Compressor is drawing high Amp readings. It is still within its rating of 19.7 Amps but is higher than normal at 17.1 Amps. This is an indication that the system is not running efficiently and the Compressor is worker harder to operate. While System is running and cooling, due to the Refrigerant levels being lower and the higher Amp readings of the Compressor, it would be recommended to begin planning for replacement of the First Floor System.
