Response from DiBiase Heating and Cooling Company:
Thank you, Taylor!
Problem under control. No complaints.
Performed cooling maintenance, checked air filter. Found condensate trap clogged. Blew out condensate trap and drain. Flushed condensate pump. Checked voltage, amperage and electrical connections, measured capacitor values. Started air conditioner, checked refrigerant charge and temperature drop across coil.
Maintenance Plan Renewal 2021-2022 AC Tune Up 3 Ton Ducane R22 system with piston. Replaced filter. Ran system to find TD of 13F. Verified that neither high airflow nor dirty condenser were problems. Low superheat low TD indicates system is undercharged. Relative humidity 57.5% Considering that system is PSC with one Cooling blower speed and it is undercharged system will underperform. Searched for leaks in lineset using bubbles; no leaks present. Options are to charge system using superheat method with R-22 informing Mrs. Higgins that a leak is present and it is costly to replace either coil of an R-22 system or to replace the system. The Lavertys decided to renew plan.
AC tune tune up for 3 ton Norodyne AC system. 19 F temp split. Filter ok. Tested condensate pump. Tstat ok. All electric motors and components ok. Both coils are in good condition. Refrigerant pressures/subcooling/superheat ok. Outdoor voltage/compressor amps/indoor amps ok.
Performed cooling maintenance, replaced electronic filter with standard disposable filter. Cleaned condensate drain. Checked voltage, amperage and electrical connections, measured capacitor values, found dual run capacitor reading low. Replaced dual run capacitor. Checked refrigerant charge and temperature drop across coil. Checked balancing issues, replaced blocked filter and all lower level supplies open. Recommend closing some near the thermostat.
Mrs Smith pâ€™s existing thermostat had a bad base (was not responding to touches). She approved estimate to replace with a Pro T6 stat. Walked Mrs. Smith through use of new thermostat. Made a call for cooling. 19F temperature split. Replaced 14x25x1 filter. Cleaned EZ trap and drain. All electric motors and components ok. Both coils are in good condition. Outdoor voltage/indoor amps/compressor amps ok. Refrigerant pressures/subcooling/superheat ok. System is operating well at the time of this tune up.
Performed Precision Heating Tune Up on Gas Fired Furnace. The 16x20x1 Air Filter was clean and in good condition. Cleaned Furnace Drain Lines and tubing. Cleaned pump and tested operation. Due to having the basement area finished off, Recommend having Condensation Pump wired into the Furnace control board so that if the pump fails to pump out it will shut the system down. Homeowner wants to wait until next visit to have this completed. Inspected electrical components on furnace. Visually inspected Heat Exchanger and Burner Assembly. Put system into operation and performed a Combustion Analysis on Furnace while measuring Supply/Return Air Temperatures.
Performed Precision Heating Tune Up on Ducane Gas Furnace system. Replaced 16x20x1 Air Filter. Tested electrical components on unit. Cleaned Furnace Tubing Hoses and Orifices for Inducer Motor. Inspected Burners and cleaned Flame Sensor. Put system in operation and measured Air Temperatures and performed a combustion Analysis. Air Temperature rise was within manufacturer rating for furnace. Combustion readings were within standards. Measured inducer motor Amperage which was within rating. System is about 15 Years old. While the system is operating, due to the age of the equipment would recommend begin planning for replacement of the Gas Furnace/AC system before any major component failure occurs.
Performed Precision Heating Tune Up on Lennox Gas Furnace. Replaced 14x25x1 Air Filter. Inspected Electrical Components on unit. Cleaned all Furnace Tubing and removed and cleaned Flame Sensor. Noted debris dust in Furnace from the Metal Flue Piping. This could be due to moisture inside the Flue piping creating some corrosion. Vacuumed Furnace cabinets and put system in operation. Performed Combustion Analysis on Furnace and measured Air Temperature readings. System operating within manufacturer specifications at this time.
Install a new 40/5 Mfd Capacitor on outdoor unit. Install a new 10 Mfd Blower Motor Capacitor. Test operation of system upon completion. 9/3/20. Installed both 10 mf blowe capacitor and 40/5 mf outdoor capacitor and tested system. Also performed heat tune up on gas furnace. Replaced 14x25x1 air filter. Checked all electrical conections and components. Checked gas pressure and performed combustion test. Also blew out condensate drain and tested condensation pump. Gas furnace is working fine at time of inspection. Also found natural gas atmospheric water heater to be over 9 years old recommended replacement due to age of water heater.
Returned to site to test refrigerant charge. Found indoor temperature set to 75 and temperature was at 75 in the home. Turned system on and measured refrigerant charge. Subcooling was at 8.5 Degrees and refrigerant levels were to standards. Took air temperature readings which measured 53 Supply and a 74 Return. System is operating to standards at this time. Will continue to monitor the system as we perform Tune Ups in the future.
Service call that the thermostat was blank and the system was not cooling. Upon arrival found the Condensation Pump running but was not pumping out. Cleaned Condensation Pump, Vinyl Tubing, and EZ Trap. Put system back in operation. Filled pump multiple times to ensure it was pumping properly. Vinyl Tubing appears to be in poor condition where it discharges into the Drain behind the Washer area. Vinyl Tubing appears to run up into the attic space and back down into the drain. Would recommend replacement of the Condensation Pump and Vinyl Tubing to avoid any further issues. While testing system found refrigerant charge to be slightly off. Adjusted refrigerant charge, charging by Subcooling. We will schedule a follow up visit to recheck the refrigerant charge. If charge is low again, this would indicate that there is another leak(s) in the system. System is running to standards at this time.
Installation of new Indoor Coil under Parts Warranty Only. Pump down and recover refrigerant in system. Disconnect and remove existing Coil. Disconnect any venting and/or additional components to access the Coil. Install new Indoor Coil and Braze in connections with Nitrogen flowing through system. Pressure test system up to 300 PSI of Nitrogen and test all connections to ensure there are no leaks. Hold Pressure for 10 Minutes to ensure system is holding pressure. Evacuate system to below 500 Microns. Weigh in complete charge of 410-A Refrigerant. Test operation of system and charge system to correct Subcooling levels. 6/15/20. Replaced indoor coil. Re- connected condensate drain line and re- connected refrigerant lines and furnace exahaust. Pressure tested seem with 280 psi nitrogen and soap checked. Vacuumed down system to 400 microns and added in factory charge. Checked temperature spli at indoor coil. Temperature split was 18 degrees. Pressures were 220/105 with 7 degrees of subcoo
Performed Precision AC Tune Up while onsite completing the Indoor Coil Replacement. Inspected 14x25x1 Air Filter. Filter was clean and in good condition. Cleaned EZ Trap and Condensation Pump. Filled Pump and tested operation. Inspected Electrical Components on Indoor and Outdoor Units. Outdoor Capacitor is starting to rust along the top but is still in good condition and is testing within rating. After indoor coil repair is completed, we will put system in operation and verify the refrigerant charge to complete the AC Tune and Refrigeration Repair.
Checked condensate leak, found large amount of water running from under the furnace. Checked condensate pan and drains all are ok. Removed coil access, found dirty coil. Cleaned cooling coil top and bottom. Joe will check on it next time it gets warm outside.
Service call that there was water leaking from the AC unit. Upon arrival found water along the floor around the Furnace and in the blower cabinet. Inspected drain line from the Clean-Out and found some buildup inside the Piping. Poured water into the Evaporator Drain Pan. Water was draining but was draining slowly. Blew through the Condensation Pipe and cleaned out accessible areas of the Pan. Poured water through the pan to ensure it was draining. Also cut 1â€ off the bottom of the drain pipe in the Pump to allow for better pitch of the entire drain line. Installed a new fitting connection at the Drain Pan outlet. Poured water into the drain pan multiple times to ensure it was draining and not leaking.
