With 9+ HVAC systems, there's a lot of work to maintenance the property's equipment. He kept me in the loop through out
Upon arrival tech was informed system for office was running continuously and blowing hot air. Inspected system and found the relay on the blower control board was shorted causing the blower to engage which also caused the heat strips to come on. Installed a new relay in air handler and tested heat and cooling operation and system is back operational. System is not cooling the best, it is a R22 Freon. Recommends replacing system due to age and Freon type.
Performed ESA on (1) Mitsubishi Mini Split system. All (3) zones working properly at this time. Cleaned all filters/coils, cleared drain lines, and re-secured line-set covers shown in pictures.
PERFORMED CMA INSPECTION ON 9 SPLIT SYSTEMS AND 1 DEHUMIDIFIER. SPLIT SYSTEM BG-J AIR HANDLER SYSTEMS EVAPORATOR COIL HAS A LARGE AMOUNT OF RUST ON COIL, SYSTEM WAS INSTALLED IN 2003 AND IS 21 YEAR OLD, TECH RECOMMENDS REPLACEMENT OF SYSTEM. SPLIT SYSTEM BG-J CONDENSER UNIT IS NOT LEVEL. RECOMMEND LEVELING SYSTEM TO ENSURE PROPER OPERATION OF SYSTEM, THERE IS AN ESTIMATE PROVIDED FOR LEVELING OF SPLIT SYSTEM BG-J. ALL SYSTEMS ARE PERFORMING PROPERLY AT THIS TIME. TECH CHANGED FILTERS AND FLUSHED ALL DRAIN LINES.
Tech performed esa on one system, system is only 5 months old and in excellent condition, tech did not find any challenges at this time. System is back on and operating properly at this time.
- Customer informed tech that the crawl space has excessive moisture, despite 4 dehumidifiers and 2 pumps. - Customer informed tech that their crawl space encapsulation contractor is scheduled to visit next week. - Tech informed customer of all these issues and recommended course of action. Tech examined crawlspace and discovered the following: 1. Trunk line and numerous flex supply ducts are resting on the ground. The insulation and jackets are saturated and should be replaced. 2. Line sets are not insulated and are contributing to moisture issue. Checked drain lines and flushed/vacuumed both drains. 3. PVC drain outlets discharge water onto a downward slope, pushing the water back into the foundation of the home. 4. Dehumidifiers do not seem to function correctly. Course of action: 1. Hire landscaper to install a perforated drain system to direct drain discharge away from home or re-grading slope away from the home. 2. Hire crawl space contractor to remove current standing water
Spoke with customer over the phone about repair vs. replace. He is going to speak with his wife and contact us back.
Performed ESA, tech found leak in evaporator coil. Coil was also caked up and covered in nicotine. Tech cleaned off coil and informed homeowner of findings. Homeowner stated her uncle is the one that set up today’s visit and to contact him. Field supervisor is to contact the customer to inform him of his options.
UNIT #1 (300 WING)-4 TON TRANE SPLIT HEAT PUMP
UNIT #8 (DINING ROOM)- 3 TON TRANE SPLIT SYSTEM HEAT PUMP
Upon inspection on System #6 tech confirmed leak at evaporator coil on 2 year old system and will need to order new coil. System #7 has 215v coming into unit and 24v coming out of transformer but is not coming back through alarm relay. Alarm company needs to replace relay to get unit back running.
Dropped off reserve tank of nitrogen. Left 01451 filter dryer.
-Installed EZ Trap on Air Handler 3 & 4 per prior approval. Insulated trap with insulating tape, cleared drain lines with compressed nitrogen. -Replaced 7.5 mfd outdoor fan motor capacitor on HP-4 per prior approval. Observed no status light at heat pump control board. Verified no voltage at heat pump by jumping Y and R circuit. Verified air handler disconnect in on position. System is likely in need of demand tech to diagnose. Thermostat is not blank but shows low battery warning.
-Performed CMA Full Service on 9 Split System Heat Pumps and 1 Dehumidifier. -Office Building System: Compressor side of dual run capacitor tested very weak. No room to add additional capacitor, recommend replacement of dual run capacitor. System is over 20 yr old R22 refrigerant. Customer should consider replacing system. -Building H: Dehumidifier run into existing drain line. Vent on wrong side of trap. Recommend adding EZ Trap to properly vent and service drain line. -Building J: Blower motor capacitor tested weak. Recommend replacement of capacitor. Outdoor fan motor hot to the touch. Compressor megged as caution. Windings deteriorating and due for shorting/failure. Signs of heat damage at condenser unit wiring. Temperature difference in cooling not as expected. Air handler approximately 20 yr old. Condenser approximately 30 yr old. R22. Replacement of system is recommended. -Building L: Compresso
Upon arrival tech began inspecting GP #2 and found Circuit 2 contact had 2 burnt wires due to loose connections causing the contactor to fail. Tech replaced 3 phase contactor and Circuit 2 began working. Compressor amps and pressures were within range. System back operating at this time.
