Arrived at customers home to perform quality assurance inspection. Inspected and tested all electrical, mechanical, and safety components. Performed combustion analysis on furnace exhaust. Verified proper gas pressure is set. All wiring is neat and secure. Exhaust flue is connected correctly. System is operating within specifications at this time.
Install new gas furnace in existing location in an auxiliary drain pan with wet switch. Install a new 14x25 Return drop with Filter boot. Install a new 16x25x1 Filter. Install Transition between the Furnace and Coil. Adapt 4" Metal Flue Piping from Furnace to Flue Pipe. Adapt gas piping to furnace and leak test fittings. Install new electrical box with outlet and switch for unit and complete electrical connections. Install an In-Line Blower Motor Surge Protector. Test operation and fill out Install Checklist Form in system, complete invoice summary, provide homeowner instructions, and clean up work area.
Rewired humidistat for 1st floor system. (2) Six Month Inspections. Checked all wiring. Checked all electric motors and components. Measured temp rise. Measured static pressure. Downloaded CoolCloud updates. Combustion/draft test: Good for each furnace. Both furnaces are operating well at the time of six month inspection.
Removed old outdoor unit and indoor txv. Installed new indoor txv. Install new pad for outdoor unit and set new unit on that and leveled it with iso pad too. Tested out and did the form.
Inspected unit size and building characteristics. There is large area of first floor that is open to second floor. Checked inside unit for air leakage and checked air filter and airflow settings. Adjusted airflow +10%. Customer stated unit would only cool to 77 degf on very hot days but humidity is in low 40% range. Informed customer will look into previous system size and quoted size. Indoor coil is 3 ton coil. Ductwork is 8x24.
Indoor Wet Bulb 63. Outdoor Dry Bulb 93. 18F temp split. New filter. Blower speeds ok. Will schedule appointment for Joe to discuss ductwork modification. Adding a system to attic.
Performed Quality Assurance on Two Amana Gas Furnace/AC systems. Completed checklist form in system. Addressed any issues that could be corrected at this time. Homeowner asked about airflow to the laundry room right above the First Floor unit. Closed damper down on Vent and homeowner will monitor. Completed checklist form in system. Need to submit PECO rebates for homeowner. Took picture of PECO account information. This did not pas QA Inspection.
Tore out existing 100k btu furnace and 4 ton A/c, tore out existing 80k btu furnace and 2.5 ton A/c. Leveled and installed two new pads for outdoor units. Installed new disconnects and whips for each outdoor unit, 4 ton outdoor has Surge protector. Installed new 7/8 3/8 line set for 4 ton A/c unit. Installed new 3/4 3/8 line set for 2.5 ton A/c unit.installed new txv for both systems. Installed new supply plenum and adapted to existing return for both units. Installed new condensate pump for each system and made all connections. Installed two new t-10 thermostats and programmed for each system installed one Aprilaire 600m manual bypass humidifier on 100k btu furnace also installed one aprilaire 500m manual bypass humidifier on 80k . Both systems tested and are working properly. Thermostats and system went over with customer.
Performed gas heat check ups on two furnaces, attic and basement unit, check electrical low and high ok replaced filters, cleaned flame sensor check blower motors and capacitor ok performed combustion test cycle both units ok
Performed two ac tune ups under service plan, attic and basement unit, check electrical low and high ok replaced filters, flushed drain attic unit does not have a way to clear drain, flushed drain from coil pan seems to be ok, check temps splits after adding refrigerant ok, blower motors and caps ok, check outdoor units capacitor and contactor both capacitor and just at the 6% tolerance, both units were low on refrigerant quoted for the first two lbs and for any additional pounds, customer ok added total of 5 lbs for both units now both units are running at 10 sub cooling + or - 3 degrees both indoor coils are leaking emailed proposal to replaced coils.
Performed cooling maintenance, checked air filter ok. Inspected cooling coil, cleaned condensate drain and trap. Checked voltage, amperage and electrical connections, measured capacitor values ok. Started air conditioner, checked refrigerant charge and temperature drop across coil.
Performed cooling maintenance on 2 air conditioners, checked air filters. Cleaned condensate drain. Checked voltage, amperage and electrical connections, checked blower motor bearings. Measured capacitor values. Started air conditioners, measured refrigerant charge, checked operation and temperature drop across coils
Found water all around furnace in basement. Found that after opening up coil door that the condensate pipe had clogged. Found water all Down inside blower cabinet also. Blew out drain and condensate line began to drain. Cleaned out blower cabinet as well as possible told homeowner about my concern of water being pulled up into blower moter and board and burning them out. Cleaned as well as possible with towels. Found no saftey on drain line so recommended installing an ez trap to help prevent this issue in the future. Installled ez trap and also replaced dirty 16x25x1 air filter.
Found no evidence of water from second floor furnace at time of service. Hot water heater is past it lifetime expectancy. Keep a eye on hot water heater, and HVAC equipment.
