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.

BIG disappointment




Review of Supreme Service Today

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.

Unit is operating but we need to return with correct set of 1 &1/4 flanges. The top flange is leaking through the metal itself. The leak is very minimal but needs to be fixed. It is my fault I ordered the wrong set of flanges to begin with. I ordered 1&1/2. It should take me only 1&1/2 hours to complete the repairs. The unit is heating for the time being.

Need to replace a Bell and Gossett circulator Pump and flange. Water is pouring out of the flange and pump body. The boiler is not operating at this time. The pump has been isolated so it’s not currently leaking water. I completed a commercial quote sheet and will submit it to the office to process ASAP. Customer has not received or lost the estimates made by Colin and would like those sent over as well. I took pictures of the pump and recorded the model number.

Upon arrival I found neither unit heating at all, using only electric heat. Found W at thermostat for unit 1, bar area, not connected properly at thermostat. Removed wire, respliced, then reconnected. Heater pack calling now but disconnect wasn’t feeding any voltage. Electrician came and fixed disconnected, once power was sent to heater pack it started operating. Also found blower relay on heat side, low speed, wasn’t phased correctly and running backwards. Corrected and tested all fan speeds. Then went to unit 2, dining area, and found blower running and heater pack contactor pulled in but pulling very low amps. Switched wires for phase by swapping L1 and L3, returned power and heater now pulling 35amps, too high for 20amp breaker. Electrician replaced breaker with 35amp so we can run heater pack at 100%. In summary, bother Heater breakers should be replaced with 40amp, new wires need to be run, unit 1 disconnect should be replaced, and unit 2 needs to add a disconnect.

Upon arrival customer explained that most of church wasn’t getting heat. Found both boilers not feeding water to radiators because of low water pressure. PRV Valve for boiler 1 was stuck, released with manual control and it regulated pressure normally afterwards. Quoting customer to replace PRV on boiler 2 because it is leaking and will not feed unless manually overridden. Found boiler 1 operating normal after bleeding air out. Boiler 2 also has leak on sight glass and gate valves in tank, quoting to replace. Finally I found thermostat for Sunday school not wired properly, corrected, and other thermostat is going bad (leaking mercury, quoting to replace). Both boilers are operating at this time but boiler 2 needs PRV valve replaced, sight glass with gate valves replaced, and thermostat on left side hallway replaced (mercury type).

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.

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
