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.

Thank you very much for your kind words! We really appreciate you taking the time to share your experience with Supreme. We look forward to working with you again in the future!
The Trane unit that had the shredded belt the other day is not heating because pieces of the belt somehow caused the heating coil to break. I had voltage everywhere but no amp draw. I tried switching the phase but that didnâ€™t do anything. Unfortunately the heater package was damaged and needs to be replaced. I made a commercial estimate that the office will need to finalize as well as check into warranty status for parts and labor. The unit is less than 1 year old. I worked a little past 2 hours but only billed for 2 because after 2 hours I was working on the newly installed Daikon unit. Only one side of the auxiliary heat strips were energizing. I ran a wire from the control voltage coil of the working side to the control voltage coil of the other side and cycled the heat. Now all elements are operating. I believe it was a thermostat wiring issue and number of wires.
Large dinner party taking place. I arrived without calling because it is a commercial call. Maurice the manager would like to reschedule. I called Darlene.
Up on arrival for no heat call on 01/15/2020 . Found blower motor belt A50 ripped in pieces. Replaced belt , made adjustments to the motor.tested sustem for operation. System operating normal at this time.
Complaint of loud noises and excessive noises coming from the radiators when heating. The steam boiler was 1 month ago by Supreme Service. The first thing I checked was the pressure control and found that it had been set higher than is necessary. I lowered the control to .5 - .75psi which is normal residential steam boiler operating pressures. I ran the unit and observed normal sounds coming from the radiators. While in front of the boiler I noticed a very small amount of water leaking from around the sight glass. It was a very small leak but I fixed it nonetheless. I took pictures of the leaking area and of the pressure control. All other aspects of the installation looked very clean and top notch. I checked the automatic water feeder while there. Customer said the thermostat would lower the temperature drastically during the night. I disabled the programming function and explained to the tenant everything I was doing. I also set the thermostat to heat only because the other optio
Up on arrival for no heat call on 12/23/2019. Found faulty gas valve. System is 2005 . Recommend to replace system. Customer requests estimate for new system central air and heating next Monday 12/30/2019 9 to 12
Upon arrival I found system off at thermostat, customer running heaters. Called for heat and indoor fan started running. Went to outdoor unit and only compressor running. Shut off HeatPump and checked capacitor, in spec, all wiring looks good too. Restored power and reversing valve switched over and fan started running. Unit was cycled on defrost, customer was concerned fan wasnâ€™t running so they shut it off. Once system came back on it exited defrost and started running normally. Showed customer how defrost works so they know what to look out for. Unit is running without fault and didnâ€™t have a problem.
Up on arrival on no heat call on 12/19/2019 system was not working. Found extremely clogged air filter 16x25x1 . Removed air filter, cycled the power. Unit fired up right away. Checked all the electrical components, took delta T . System operating normal at this time. Told customer to get air filter ASAP. Calle Property owner multiple times . No response. Changed card the one we have on file for advanced diagnostics .
Upon arrival I replaced flange for pump that was replaced on Friday. Removed flange and nipple from current piping and replaced both flange and nipple with new. Used pipe dope to seal threads. Opened up valves and checked for leaks, none found. Then shut off all water to boiler and replaced PRV valve. Also used pipe dope to seal threads. Checked for leaks and none found. Opened up valves and set PRV for about 28psi. Then went to Sunday school classroom and replaced failed mercury thermostat with Honeywell single stage thermostat, tested. Finally I went to replace sight glass kit and found it is the wrong size, need 10 inch kit instead of 12 inch kit. Sight glass was leaking during initial diagnosis but currently isnâ€™t leaking anymore and customer said he would like to hold off on replacing for the time being. Office adjusted invoice accordingly since sight glass wasnâ€™t replaced.
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.
On arrival found system not operating found feeder valve wired incorrectly and boiler was empty .i then corrected wiring mistake and replaced thermostat.also opened the sight glass valves to monitor water level .unit is operating normal at this time
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 itâ€™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 wasnâ€™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, wasnâ€™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.
Up on arrival on no heat call found inducer fan motor is very loud and sounds like itâ€™s grounding, board is giving out deferent codes every time I cycle power. Board and inducer fan motor needs to be replaced.
Up on arrival on no heat call found unit 2. Had missed wired at unit and thermostat. On unit number 1 found disconnected that is bad for electric heater.

Recommended Drain pipe repair also ez trap installation & Evaporator coil needs to be cleaned and DUCT Cleaning and and blower wheel cleaning to run the unit on Ac mode normal. I explained the customer what I found and what
Upon arrival customer explained that most of church wasnâ€™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).
On arrival found system not operating normal,found bad thermostat,also found bad gas valve .unit is about 30 years old , recommended replacement vs repair .customer is scheduled for an estimate on Friday

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.

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.
