Review of Supreme Service Today

We received service from a very nice, helpful, and knowledgeable service representative. Our only comment to improve service was when we called in in the middle of the night due to odd and loud noise from heating unit, it would have been helpful to have someone on the line who could tell us what to do, was it important to shutdown the equipment, if so, how, or could we leave it running until a service representative arrived.

I checked the air filter and it is good for 6 more months. Coil and blower wheel are clean. I operated the unit on #12 heating mode. I fine tuned the blower speeds from 2,6,10,11 to 2,3,11,12. I confirmed proper flow rate and heat of extraction. Loop pressures are at recommended psi. I checked the electrical wiring and electrical systems, all are within specification. I checked auxiliary heat strips. Unit operating normal. Customer has all recommended accessories like WHSP, wet switch and bypass humidifier. Customer is set for winter.

Both geo units share the same ground loop, which had lost all pressure. The split system was going out on high pressure lock out. I pressurized the ground loop to 65 psi and cleared faults from the unit. I bled a small amount of air from the pump. I opened the valves all the way to not restrict the flow of water. I slowed the 7 Series vs pump to 25 & 75. I let both units run at the same time to make sure that each unit had the correct pressure drop and that this problem cannot happen again. I checked cooling across the coil and had 20 degrees delta temperatures. I also had normal loop temperatures and heat of rejection. Unit operating normal. I reminded the customer that service memberships check these issues out twice a year.

I found the blower cabinets door insulation completely pulled against the blower cutting air flow. I secured with some spray glue and tape and then operated the unit on second stage cooling mode and checked everything, refrigerant pressures, pressure drop, heat of rejection, capacitor, fault status, and most importantly checked cooling across the coil, 81.2 return, 60.1 supply. Unit operating normal.

Found unit with contactor humming . It was pitted and allowing voltage to go to L1 to t1 . Gave costumer quote and replaced it . Unit was operating when I got here but was previously in a lockout for FP1 . Suction pressure 112 and head pressure 380 . Water loop 45 psi in and 40 psi out , 49 degrees in and 45 degrees out . Supply air 98 degrees and return air 70 degrees . Ohmed out resister and it was at 24,000 ohms and my temperature was reading 47 degrees on my aid tool so it was in the range . I believe it could be faulty due to the rest of my numbers being in -line . Also gave costumer quote to replace his hot water heater . Costumer has heat and system is working properly at this time Replace contactor
