DCM1: AC complete, replaced 20x20x1 filter. System is operating at this time. System appears 1lb low on R410A however due to the amount of build up on blower wheel won’t be able to tell exact refrigerant pressures. Indoor coils are above 35* so they should not freeze but as the blower wheel gets more build up airflow will drop and could potentially freeze the coils. System is under warranty at this time, warranty expires 2026-05-09. Photos and maintenance checklist attached.
Confirmed roof leak isnt from heating and air unit. Identified roof is leaking into the lower corrugated metal roof below the actual roof. That corrugated metal is cut at the HVAC unit. The water is dripping from the corrugated roof onto the ducting and then running under the duct and dripping onto the floor. Couldn’t identify leak point, somewhere water is leaking onto that corrugated roof and then flowing the length of the roof until it leaks onto the ductwork Photo and video attached Removed insulation under duct that had been ruined by water to help identify the leak.
DCM1: Heat complete, replaced 20x20x1 filter. System is fully functional and operating within manufacturer specifications at this time. Found extra filter in return grill, removed filter. Using two filters can cause restrictions in air flow not allowing system to operate to its full potential.
Open return, no return duct work. Offered to clean closet because that is the “return duct” homeowner declined. Blower wheel is clean and coils are starting to rust but overall clean.
Replaced OEM indoor blower motor. Disconnected high and low voltage wiring from control board and fan housing Removed existing blower motor and fan housing from furnace cabinet. Separated motor, fan and housing. Installed and secured new motor into housing and secured fan to motor shaft. Installed and secured motor, fan and housing into furnace cabinet Connected high and low voltage wiring to control board and fan housing Tested system in Fan, Cool and Heat modes. System functions as designed Homeowner was present for all testing
Arrived to No Cool Identified failed indoor blower motor, open windings from common to run Spoke with analyst team for approval at (469) 991-7976. Make: GOODMAN Model #: GMS80804BNBD Serial #: 1607007962 Work Order# RRK068706 Authorization Code : 2177
Checked unit for any possible leak points. Identified possible leak point under burner compartment. Sealed metal seams. Photo attached
Arrived to water and lack of cooling Crawled around for an hour checking roof seams with a water sprayer, Identified leak in roof, video attached Checked system, diagnostics photo attached. RTU #1 is slightly low on refrigerant ( 2-3 lbs ) not to the point where it is effecting the ability of the system to cool. Thermostats in building are reporting a desired AC temp of 73. Both systems are maintaining 73* with duct temps reporting 69 and 71.
DCM2: AC complete, replaced (8) F20x20x2, checked (2) AX49, both systems are fully functional and operating within manufacturer specifications at this time. Leak still undetected; Had helper spray water inside and outside of the unit, while I searched for leaks for an hour. TXV could possibly be malfunction causing the coil to freeze but no signs while performing test, also possible blower motor failing causing evaporator to freeze but blower motor amp draw had no indication of failure and belt was tight. Subcool and super heat are within designed parameters, TXV and blower motor don’t seem to be malfunctioning.
Arrived to conduct inspection of HVAC equipment and performance System is a 2013 Carrier, Furnace and A/C split system that is designed to produce 3.5 tons of cooling capacity and 88,000 BTUs of heating capacity. Ductwork is properly installed utilizing distribution boxes. System would benefit from a second filter and return plenum mounted opposite the current plenum. Blower wheel has a moderate level of dust due to the air velocity, causing filter offload, moving through the single filter. Photo attached Cooling : System is fully functional. Refrigerant pressures and temperatures are appropriate for both indoor and outdoor conditions. 19* temperature splits between return and supply. Diagnostics photos are attached Heating : System is fully functional. Removed blower housing and visually inspected heat exchanger. All components are operating as designed. Temperature rise of 59* is within manufacture specifications ( 30-60* ). System is on the high side of acceptable. Diagnostics an
DCM2 complete; Heat; (8) F20202 and (2) AX49 replaced. Systems are fully functional. All components are operating within manufacturer specifications. Gas pressures and temperature rises are within design tolerances. Heat checklist attached.
DCM1 complete; AC; (1) F20201 replaced. System is cooling with a 9* temperature split from return to supply, should be 61-20*. Superheat is elevated at 30* with no Subcool present. System is low on refrigerant. Identified leak in evaporator coil. Video attached
Arrived to No Cool on Upstairs system Identified weak capacitor. Replaced capacitor and tested system. System functioned for 10 minutes and seized drawing 38amp which was LRA for the compressor. Compressor was extremely hot, cooled down with water and tested system. System functions as designed. System does have a high amp draw ; 6.9 for a RLA of 7.7. If system seizes / fails again, compressor replacement is likely. System is still under warranty. Possible cause of early compressor failure, identified improperly mounted and insulated TXV sensing bulb. SH was initially 2-4*, once repositioned and insulted SH increased to 11-13*. Low SH can causing liquid slugging not the rotary compressor System is operational, refrigerant pressures and temperatures indicate the system may be slightly low of R410
