System has been off since 3PM yesterday Customer said there was an “acidic smell” When I walked in front door I could smell very similar to a recent “dirty sock syndrome” situation for another HVAC system I experienced not too long ago. Ran furnace for 5 minutes and took off indoor coil panel. It did not smell there at all. Replaced Aprilaire 213 filter provided by homeowner. Removed water panel for humidifier. Homeowner will buy Aprilaire 35 water panel to replace. Also ran the system with the AC coil door off and therefore directly blowing on us and smell was not present. Combustion and heat exchanger tests: Pass Ambient carbon monoxide in ducts 0 ppm. Electronic gas leak detector t at for all gas piping near furnace: Pass 0 gas leaks detected there, While inspecting indoor coil for smells I used UV light and we found points of refrigerant leaks there. Had homeowner use UV light and glasses to see dye as well. Condensate pump is dirty I added treatment tabs. Left estimate

Installed new gas furnace. Adapted return and placed existing coil on the new furnace. Sealed all air penetration on indoor unit. Adapted flue pipe and gas line to new furnace. Adapted high volt and installed new outlet and switch with surge protector. Adapted condensate line and installed new condensate pump. Installed new ecobee thermostat and wired in low volt with safeties. Cleaned up work area and tested out equipment.

Arrived for heat tune up 80,000 BTU Carrier Infinity furnace. Replaced filter, cleaned flame sensor, Considerable rust on primary heat exchanger. Combustion test revealed dangerous levels of carbon monoxide in flue gasses. I called Pierce Phelps West Chester to determine warranty status of heat exchanger. It is covered under parts warranty. I left estimate to replace heat exchanger. The better option is to install new furnace especially considering the high failure rate of this particular heat exchanger. Discussed with Judy. I will email management to be able to provide her quotes/options to upgrade furnace and for full system (AC+ Gas furnace) AC is 2.5 Tons Furnace is 80,000 BTU natural gas high efficiency. The intake was cut and capped (to the outside) and the furnace was drawing from basement as an intake because Judy thought the manure smell was getting into house via intake. I told her it is better to draw from outside. It’s just a small piece of 2” PVC to reconnect. See p

6 month inspection for 3 Ton Bosch Inverter (10KW electric heat) 18x20x1 filter ok Indoor and outdoor coils in good condition. Inspected wiring and controls, incl. fan speeds. Blower motor surge protector and outdoor disconnect surge protector installed. 10KW heat kit amps with blower = 44 Good Measured temperature rise and static pressure heating Measured temperature split and static pressure in cooling Cleared EZ trap; drain ok Sealed a couple gaps in return panning where it meets trunk in basement Heating refrigerant pressures: 135/348 Good System operating well at this time. Homeowners want to become plan members but aren’t sure if they have already paid/signed up. Please follow up.

Recently installed propane gas boiler not heating apartment. Checked boiler operation how water works. Checked all three zones. Found apartment return valve closed (probably when purging during installation). Open valve and test operation. Bleed all three zones to make sure no air was left behind after installation. Ok all zones heating account to outdoor reset curve temperature. Taste temp is 143 F. Outdoor temp 58F. Checked outdoor reset temps 130=68 and 180=40 cycle boiler couple times ok.

estimate created.

Performed QA on Laars Boiler install. Spoke with Karen about the system and install. She asked if I could turn the temperature up on the domestic hot water. Adjusted the mixing valve to increase the temperature from 116 Degrees to about 121/122 Degrees. Inspected piping and checked gas piping for leaks. Reviewed programming and Dipswitch settings on the boiler. Completed checklist form in the system. No follow up is needed.

Quality assurance 3 Ton20 SEER Bosch Inverterwith 10KWelectric Heat Kit: Walked homeowner through replacing 18x20x1 filter Help set up comfort setting (home, Away, Sleep on Ecobee thermostat) Set up dehumidify using cooling equipment at Ecobee thermostat 60%RH. 3° Overcool max, Inspected all aspects of install:ductwork connections, hardware. Lineset penetrations,wiring, etc. outdoor unit and disconnect are level. Penetrations are sealed. Added treatment tabs to evaporator drain pan. Measured temperature split and static pressure. Used manufacturers airflow performance chart to make sure fan speeds are correct. Monitored R410A refrigerant pressures and diagnostics:130/290 12SH 8SC Good System is operating well at this time. Install passes quality assurance.

Removed old oil boiler and oil tank, pumped all the oil out and carried oil tank to scrap pile, installed new boiler, ran flues intake and exhaust all 3 inch to outside penetrations and sealed around, installed new propane gas line from unit to outside meter, installed new outlet with new box, installed outdoor sensor and sealed penetrations, adapted supply and return for boiler with mixing valve, expansion tank, pressure relief valve, added air eliminator and water fill, kept all existing zones, connected condensate pump and vinyl tubing, tested out.
