Performed 3 system pma cooling maintenance replaced filters checked electrical components and refrigerant charge all systems are operating properly at this time
I performed a one system maintenance gas furnace in the attic in the garage. I looked over all the low-voltage checked in compaciter blower motor and treated and blew out the drain line. I’ll check the charge on the capacitor on the outdoor unit and wash the system off. The system is running an operating like I supposed to at this time.
New 2 system CCM- Checked operations of the air conditioning systems. Replaced filters, checked amp drawls and capacitor outputs, checked delta T, cleared drain lines, checked refrigerant levels and cleaned outdoor condensing coils.

Replace reversing valve for Lennox heat pump Plus refrigerant Replaced reversing valve and filter dryer. Pressure tested system and pulled a deep vacuum. Charged system up with six and a half pounds of 410a to correct factory requirements. System is currently cooling at manufacturers specifications.
2018 Lennox heat pump low on refrigerant. Customer decided to approve the BETTER option with adding refrigerant and preforming a electronic leak search to pinpoint leak. I did find leak on reversing valve in heat pump. I added 4.5lbs of refrigerant to get the system cooling until repairs. I will be calling Lennox Monday morning for part availability and work up quotes for customer. Pics uploaded, 14x20x1. No warranty on refrigerant
Customers now maintenance agreement customer no diagnostic fee Technician inspected upstairs system, and during time of visit the upstairs system is operating and maintaining the set temperature. There may have possibly been an electrical storm or possibly thermostat issue. However, at this time the system is operating normally with a good refrigerant level. Customer would like to start maintenance contract with us and we will schedule for system cooling maintenance in the near future. Upstairs filter is 16 x 25 x 1 Mid-level filter is 16 x 25 x 1 The basement system filter is a 16 x 20 x 1 And his upstairs office above garage uses a 14 x 20 x 1 filter
Both in-line drain safety switches are faulty. Gave estimate to replace both with a SS1 safety switch. Customer said he will think about it. Have them both bypassed for now and customer is aware that water damage could occur if drain backs up.
Arrived and discussed issue with customer. Customer stated aim floor systems outdoor unit was make a metal on metal sound. I tested system indoor and outdoor units. I checked refrigerant charge and amp draws on outdoor unit. At this time I could not duplicate the noise the customer reported. Everything sound currently is normal operation. I did notice possible low refrigerant charge and also dirty outdoor coils. I recommend getting a maintenance plan and discussed option with customer. If noise comes back we will warranty our diagnostic fee and only charge for repairs.
Performed 2 system cooling tune up. Checked both 16x25x4 Honeywell media filters, both are in good condition. Cleared drain lines. Cleaned outdoor units and checked refrigerant charge. Both systems are clean and operating properly.
