I arrived for a heat pump not keeping up with temperature. I started downstairs at the air handler. I had a 64 return and a 92 supply heat pump was running only but auxiliary was not running. I opened up the air handler. The board had a (E0) code. Which is a EEPROM malfunction. I checked all my connections and reset the system for 10 min . I turned the system on and the thermostat read heat 2 which is the auxiliary heat kicking in with the heat pump now my temperature went from 92° supply to 119° system is back up and running again. I did put a call into carrier for them to call me back . so I collected for my time and diagnosis for today.

Replaced 70/7.5 uF dual capacitor at outdoor unit. Origin capacitor was very weak. Reading 28uF. Afterwards tested system. Measured amp draw of start winding to capacitor 8.6A Good. Measured temperature rise @ air handler. 66-86=20° Good Outdoor dry bulb temperature 16°F System operating well at this time. Collected balance

I arrived for a thermostat not working. I found condensation pump was running nonstop. I traced out my 3/8 tubing and it ran outside with the line set. It had about 6 foot a line outside the wall, it was frozen, I cut the line out, sealed up the access. Then I rerouted the 3/8 tubing to the basement sink and used PVC to guide water into the sink for the 3/8 tubing. No charge . The system is back up and running.

Neighbor came over and told me she can smell oil. Duplex house. She lives on the other side. Robert doesn’t come down to basement often Found copious oil in equipment pan, blower compartment and filter rack. Cleaned as much as possible and left paper towels to absorb oil that is under furnace where I cannot get to it. Replaced failed wet switch. Used (2) burner gaskets folded in half and placed under bottom half of burner so that burner is pitched in such a way that oil will spray into combustion chamber. Changed post purge time from 0:00 to 1 min. Completed oil Heat tune up. Replaced Aprilaire 413 filter. Heat exchanger and flues are clean. Replaced RF1 oil filter, replaced .60 80A nozzle and arranged electrodes. Combustion smoke and draft test: Pass Set new humidifier to 35%. Pad is new. Tested operations and water leaks. We will have to make a return visit to pick up the towels that are used to wick up any oil left in pan and assess the oil leak situation further. After my fi

Luis 1-9-26 perform heat tuneup on a one year-old trane fully communicating heat pump system. Went to the indoor air handler and outside heat pump check checked refrigerant charge through thermostat no error it’s showing. I also tested 10 KW back up heat ok. Replacement of 413 filter. Refrigerant levels and Oreos. I corrected low voltage wiring on outside and used different anchor for thermostat base. Cycle heat pump ok. We also lock out electric heat at 35° per customer request.

Performed precision a/c tune up on amana a/c system. Replaced 18x24x1 filter. Checked all electrical connections and components. Cleaned ez trap. Checked temperature split. Found no surge protection on Ecm blower motor, provided estimate. Also found dirty outside coil, provided estimate to clean outside coil. Checked refrigerant pressures and temperatures at indoor and outdoor units. A/c is working properly at time of service.

Upon arrival, I performed maintenance on mini split system. Washed indoor air filters. Inspected evaporator coils and blower assemblies. Cycled all mini split heads in cooling. Ensured all mini splits head had proper drainage. proceeded to outdoor unit. Check refrigerant pressure and temperature. Inspected outdoor coil and condenser fan. Inspected electrical connections and components on outdoor unit. Mini split system is operating appropriately at this time with all heads supplying appropriate temperature drops.

Upon arrival I found capacitor terminal and wire melted. This was due to a faulty capacitor. Replace capacitor under warranty and replaced wire. Cycled system to ensure proper operation and checked amp draw. System is operating appropriately at this time. No charge due to recent part failure.

Luis 7-1-25 customer called in for no cooling on bedroom Mitsubishi mini split (two indoor match to one outdoor heat pump ). Other zone is working fine. Found unit going off on thermistor open for more than 8 seconds. Water sensor is in series with thermistor. Found some condensation issues n sensor pins tripping the sensor. Dry pins and check drain ok. Test operation of system did not find any blockage on drain line. I did notice lot of bacteria and dust on wheel. Provided estimate to clean both indoor heads. And also installation of uv light for both indoor heads.

Installed new humidifier on the return duct, installed new humidistat, installed now copper water line for humidifier, installed new drain to condensate pump. Installed new dehumidifier in a new drain pan with a float switch in it, ducted into supply and return duct work. Installed new drain to condensate pump. Tested humidifier and dehumidifier.
