Warranty. Found lose connection at blower capacitor from pm prior Friday.
Completed heat check and filter change. Estimate provided for weak capacitor replacement 3 separate units. Systems all heating as designed.
I found unit heater two with a dirty flame sensor. I cleaned the flame sensor and reset the unit. The system is operating at this time. Original flame sensor reading .4, after cleaning the reading 5.1.
All 6 Carrier units had low temperature splits. This is due to the location of the units and the dirty nature of the environment. They will require a deep cleaning using a portable sprayer as well as chemical condenser cleaner. Customer will need to move items on pallets near the units to prevent water damage.
Cleaned out all condenser coils of all Carrier Units. Verified all Carrier Units are cooling at this time.
I recommend replacing the (2) compressor contactors for units 3 and 4 SN: 1608G20183, and 1608G2018. They are both worn and pitted. This quote includes all parts and labor required to replace the 2 contactors. This quote is valid for 30 days. 08/30/2021 Installed new compressor contactors on both units, after contactors been replaced I checked operation of cooling mode at this time everything is working ok
Performed full cooling maintenance. We checked mechanical and electrical components. Changed filters and performed a basic condenser cleaning. We also checked temperature splits. Temperature splits are out of the proper range. Units will require a deep cleaning with water and chemical. Quotes have been sent for repairs
Assisted kellan with scheduled maintenance.
Drain clean out that customer wants replaced is to close to very large and very heavy equipment. We will only dig if equipment is moved. It is to dangerous to excavate this close to that much weight. Ink has dried and turned into a rubber substance tat cannot be removed with jetting or cabling.
Upon arrival 3†cleanout for floor drain line was holding water. Attempted to auger line but hit a significant blockage 5’ in. LBA tech had the same issue on the previous visit. Each floor drain held water at different levels so attempts were made to clear them. It’s determined that line is full of ink sludge. Water and plunging moved the blockage down the line, but drains still hold water. Recommend repairing of cleanout line so that a sewer machine or jetter can properly clear the line.
I preformed a scheduled maintenance and safety inspection on six package units for heating operation. All systems are operating properly and within factory specifications at this time and all filters have been changed.
