Great Service




Review of Supreme Service Today

Tech dispatched promptly. Nikolai was courteous and extremely helpful in explaining the issue and options without pressing for sales. We ended up getting HVAC replacement since our unit was 31 years old.

Performed pm on all 3 geos. This was first pm service for customer since install and they wanted efficiency checked, didn’t feel they were running efficiently. Found water flow rate for all 3 were too high, adjusted down to get better heat extraction rate. Changed fan speeds on units 1 and 2. Measured amp draw of compressors, blowers, loop pumps, aux heaters. Tested Dhw operation. Measured delta air temps, delta loop pressure and temps. Checked filter, blower, and coil cleanliness. Flushed out drains with hot water and brush. Electrical inspector was here during service. Only issue was a knockout in a disconnect was open, once I covered it with knockout plug he passed customer. Put sticker on 7 series.

Upon arrival customer explained that top floor split system still had water leaking. Found unused drain taps, red caps, were not sealed and were loose, letting water come out and onto filter. Removed caps, used tephlon to seal, then tightened. Tested drain and found it is clearing normally. Drain pipes all pitched correctly. Then customer explained that AWL for 7 series wasn’t working. Helped them set it up and connect to router, awl now working. Finally customer showed me 5series packaged unit that is leaking as well, drain pan filling up. Found pvc pipe behind unit wasn’t pitched properly. When system needed to drain quickly it was backing up and dripping. Corrected pitch and tested. Also found float switch not working, had to replace with new. Condensate pump safety wasn’t wired to system, connected to low pressure wire and tested. All units operating normal. Warranty per Alex.

Customer recently replaced the air filters. I went around and pressurized the various ground loops first. I then went around and checked the electrical wiring and electrical systems for all units, all are within specification. Next I ran each unit in high stage heating mode and then auxiliary heat mode. I confirmed proper flow rate and heat of extraction for each unit and temperature rise across the air coil. All heat strips energized in auxiliary heat and the safety overheat devices are all operational. All units are operating normal. The only issue I noticed is that none of the 3 separate main electrical panels have any form of surge protection device installed. I recommend adding a whole house surge protector to each one of the 3 panels. The 2 for the main house and the 1 for the guest house.

Thermostat had no power. Located the unit on the roof and turned the power back on. The blower came on but the compressor and od fan didn’t come on. I found the refrigerant had 0 psi pressure. The unit is older and uses r22 refrigerant. A leak search would need to be performed to find the leak. If the leak is in a coil then the coil would need to be replaced. I recommend replacing the unit but wrote up an estimate for the office to finalize.

Upon arrival I was told front unit wasn’t cooling. Went to roof and found system not running, started to remove panels when unit cycled on then off again. Connected gauges to system and found unit was tripping high pressure switch. Switch is rated for 400psi open and 300psi close, this seems a little too low for 410a System. When unit starts it pushes 400psi then drops back down to 350psi. Need to replace switch with higher rated one.

Upon arrival I found upstairs unit not running. Went to AHU and blower off, thermostat calling for ac. Went to Cube in basement and found condensate lockout code 6. Recalled all previous faults and found board only flashing 6 time repeatedly, condensate fault. Went back to AHU and found condensate Line/pan empty. Restarted unit and checked operation of ac. Found no problems with unit. Shut off system after 20 minutes of run time and inspected drain cabinet. Found drain sensor in pan had shifted and a lot of condensation was dripping right on top of drain sensor. Sensor interrupts ground so any contact with water will shut off unit. Covered top of sensor so condensation doesn’t drip on it and moved back into place. Drain was just cleaned last month and is still clear, tested with water. Unit operating normal at this time.

Upon arrival I found nobody on site. Called office and they asked me to take a look and see what I can find. During diagnostics I ran both systems and checked operation. The only vibration I could hear was coming from Daikin rooftop blower cabinet (rear system). Opened up panel to find blower wheel is rocking a little. Tried to adjust tension of belt and it made no difference. Spare cogged belt was inside of system so I tested blower with cogged belt and vibration stopped. Left AX52 belt on blower assembly instead of A52 because of vibration it was causing. Can not confirm exact noise customer is hearing because nobody is on site but I don’t hear anymore vibration from system on the roof. Unit operating normal.

Set both climate master units to call for cooling. Both units were not coming on. I tried my best to figured it out but Problem was not up to my level of experience. Customer stated that there was a different company working on both units about three days ago. I was not able to get both units to run. Our lead tech is coming on Sunday morning. Customer is having friends and family in the evening due to a loss of a family member.

I cleaned the condensate pan and drain lines and ran hot water to flush the debris and make sure it drained properly without leaks. I checked the electrical wiring and electrical systems, all are within specification. The washable filter was very clean. I operated the unit on second stage cooling mode and while I had 20 degree delta temperature across the coil, it was slow to reach it so I put my gauges on the system. While putting my gauges on I noticed refrigerant oils around the true suction valve stem. I tried tightening but I was picking up refrigerant using leak detector. I called the customer and proceeded to replace all 3 valve stems, leak check those and the braze joints and confirmed no leaks. I added 2lv 8oz of r410a refrigerant which increased my suction pressure to well above freezing, when converted to temperature. I charged until I had 13 degrees subcooling, normal Superheat and still maintaining 20+ degree delta temperatures across the coil. Unit operating normal.

Turned system on and checked operations . Took a video of the blower while running to show costumer. There was no noise and everything working . Can hear rattling from unit in conference area . Unit is right above and the disconnect and doors rattle when unit is running from vibrations. I put foam behind disconnect and I screwed cabinet doors tight to limit sound . Unit is directly above so costumer will hear some noise from unit .
