West Brandywine Township, PA

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.

Upon arrival I cycled system in cooling and proceeded to outdoor unit. Inspected outdoor coil and condenser fan. Checked electrical connections and components on outdoor unit. Checked refrigerant pressures and temperatures. I then proceeded to indoor unit. Changed air filter. Inspected evaporator coil and drain pan. Cleared and tested drain line. Inspected blower assembly and electrical connections. Checked static pressure and temperature differentials. System is operating appropriately at this time. Gave homeowner estimate to install a ducted E100 dehumidifier and a model 600 M humidifier. Collected deposit on estimate and informed him we will schedule once we get all material in stock.

Found no surge protection on blower motor , installed Ecm surge protector. Also performed precision a/c tune up on Bosch heat pump system. Replaced 18x30x1 air filter. Checked all electrical connections and components. Checked temperature split. Brushed out ez trap. Checked readings at outdoor unit control board. Checked refrigerant pressures and temperatures at indoor and outdoor units. Heat pump system is working properly at time of service.

Fully assessed no cooling situation. Found that the a/c is freezing up. Went up in attic and found blower running at air handler but r-22 pressures are low. 232/57. System is from 2004 and overall is just shot. Explained to tennet that this system needs to be replaced. Landlord is Amish. Explained to Gregory is the next step is to get someone from our office out to give a replacement quote. System is in the attic.

Upon arrival, I performed maintenance on AC system. Changed homeowner provided 14x30x1 air filter. Inspected evaporator coil and drain pan. Cleared and tested drain line. Inspected blower assembly and electrical connections. Cycled system in cooling and checked static pressure and temperature differentials. Proceeded to outdoor unit. Inspected outdoor coil and condenser fan. Checked electrical connections and components on outdoor unit. Checked refrigerant pressures and temperatures. System is operating appropriately at this time.

Upon arrival I found system was running with a 19° temperature drop. Replaced 413 spaceguard air filter and was able to get the system to run at a 29° temperature drop. System is operating appropriately at this time.
