Can’t wait for this to be done. It’s too hot for me. 5/29/19 today and it won’t be done until 6/3/19. Please hurry. The portable air just isn’t enough or they aren’t working right.

HAd Supreme Air install a brand new furnace at the residence in Nov. for a total cost of $3,600 in OCt. 2018. Thought that they would be a reasonable resource when the air conditioner needed service. I suggested that the tenant call them, when she noticed that there was so much water in the dish that took the condensate from the air unit. Was shocked to get a bill for $373.00 for such a simple job. Will go elsewhere for future service calls.

When I arrived, I inspect the indoor unit and the outdoor unit I noticed that the Freon was low on the outdoor condenser 410A Freon I recommend that the unit be filled to the right pressure for satisfactory I also recommended a membership plan. Fill unit with Freon mr. John signed up for membership as well. Unit is running well delta T is 55
Space is a church, needs to be billed commercial. Upon arrival found indoor unit running, supply air temp 82 degrees. Inspected outdoor unit and found compressor and condenser fan not running. Supply voltage good, capacitor completely failed. Replaced capacitor and system operational. Amp draws within range on outdoor unit and indoor unit operating with 17 degree temp split on return and supply air (82 return and 65 supply). Parts used: 1 x 45/5 dual run capacitor. Customer interested in commercial service agreement, return visit needed to gather unit information.
Service call on 07/18/19 On arrival set the unit call for cooling measured supply and return air temp no DT checked electrical connections checked voltage and amps checked blower motor checked air filter running normal checked condenser unit outdoor checked electrical connections checked voltage and amps checked compressor capacitor checked coil the blower is running but the compressor is not checked pressure and temp is 0 psi both gauge low side and high side checked compressor is good checked compressor wires checked pressure switchâ€™s is good I gave quote for customer to nitrogen leak search and repair customer he is not repair bc he insurance company they going to replace it for him turn off the outdoor unit from disconnect box outdoor unit is not running at this time.collected $89 dispatch fee and $124 diagnostic fee total $213 C.C on file

On arrival found thermostat needs batteries .customer used his batteries.unit is back on normal
On arrival set unit to call for cooling.found system pressures low .possibilty of refrigerant leak .unit is operating slightly above freezing.could freeze again anytime.
Replace voltage absorption system and remove excess refrigerant charge and install valve stem caps. Upon my arrival suction and discharge pressures were very high and unit had 23 degrees subcooling designed for 10 degrees. The dual run capacitor was also extremely hot because both sides values were way below specification, the fan motor side was rated for 5uf and at 1.2uf. I also noticed that there were no valve stem caps on either line. I called the customer and they approved the repair. Voltage absorption system was replaced with 35/5uf dual run capacitor. I pulled 8oz r410a refrigerant our of the unit which brought the operating pressures to normal range with 10 degrees subcooling and 20 degree delta temperatures across the evaporator coil. Unit operating normal.
Upon arrival I found thermostat off. Called for ac and checked refrigerant charge, suction pressure dropping. Unit has negative subcool and normal Superheat, system not rejecting heat. Shut off ac and removed blower panels. Found blower running backwards. Rewired phase at disconnect for blower. Returned power to unit and tested blower. Now running in normal direction so I checked refrigerant charge. 4 degree subcool, normal Superheat. Installation manual asking for 9-13 degree subcool. Added 10oz to system to bring subcool to 11 degrees, Superheat 13. Unit operating normal and indoor temp lowering. Customer then approached me about the other system that needs condenser coil cleaning. He asked that we do not clean coil because they are looking to replace that system too. Informed office.
On arrival found transformer tripped .found a short at g and c wire .corrected wires .also found bad thermostat.replaced thermostat.unit is operating normal at this
Checked AHU wiring and found a signal to the condenser. Found electrical components hanging on the outside of the AHU. Need to be put into a box, see photo. Found the condenser tripped on high head pressure. The way the unit is designed, the expelled air does not go up but sideways. The hot air is going right back into the condenser coil. If you leave the door open it helps but more on just the one side. Recommend putting in a chain link fence instead of the solid fence. The right side fan motor went out on internal overload because of the heat buildup. The motor did reset but the windings get weaker ever time this happens. Recommend changing out the motor also.
The main ballrooms condenser unit had tripped on high pressure. I applied my refrigerant gauges and reset the pressure switch and had normal operating pressures for r22 refrigerant as well as normal superheat. One of the outdoor fan motors voltage absorption system was not reading any value. I replaced the voltage absorption system and properly dressed the electrical wires within the unit and restored power. I also tightened and secured all cabinet doors on the exterior of the unit. Unit operating normal. Materials: 1) round 5uf run capacitor
Suck out sump pump and fix small leak on clean out
Unit has a bad compressor. Unit uses R22 refrigerate which by 2020 will be no longer available. Suggest putting in a 410A unit.
